The Basics About RV Solar Panels
What is an RV solar panel?
Most of us who aren’t living under a rock know roughly what a solar panel is as well as what it does. A solar panel will consist of many solar cells, these solar cells are made of a few more ingredients which helps it to absorb photons from sunlight, with which it generates electricity.
The formal definition of a solar panel isn’t very far from this, since what it is and does isn’t nearly as important as how it functions under the hood and the principles that govern it. A solar panel typically has these layers (from top to bottom): aluminium frame, tempered glass, Encapsulant, Solar cells, 2nd Encapsulant, Back sheet, Junction box.
There are three main types of solar panels: Monocrystalline, Polycrystalline, and Thin-film. Depending on the amount of state-of-the-art technology and materials involved, you can expect to pay more on a thin-film solar panel than a Monocrystalline, for instance.
How does it work?
I have to admit that the solar panel (like many other technologies) that we use so conveniently today is a technological marvel that came from the overlapping of several fields of chemistry and physics.
I used to come across semiconducting materials and solar panels in my high school’s coursework but putting such a “simple” concept into practice in such sophisticated ways and developing such a product is just unbelievable.
As we already said, solar cells are one of the building blocks of the solar panel, and also its strongest link. Solar panels convert the energy from the photons (particles of light) into direct current (DC), which charges an RV battery and the electricity is stored inside.
As sunlight passes through solar panels, photons should knock electrons away from atoms which produce electricity. With the right number and quality of solar panels, the RV battery will constantly power most of your RV’s appliances, provided the right setup.
Not all the sunlight that touches the solar panels would generate electricity though. The conversion rate of standard solar panels for RV trailer range from 10% to 15% but it gets as high as 21% on premium models.
So solar panels make electricity, but if that’s the only benefit, what makes them stand out from other alternatives? You will see below that many times the solar panels prove to be a worthwhile investment.
Are RV solar panels worth the investment?
You have probably heard that solar panels are expensive, and considering the looks and state-of-the-art technologies accumulated in a single solar panel, the price is justified. Since money doesn’t fall from trees, it is best to inspect and make informed choices when it comes to these accessories to know whether or not you truly need them.
The best thing that everyone can see about installing solar panels is their ability to provide almost free electricity. Why am I saying almost? Since as with any kind of machine, solar panels deteriorate the more they are used, therefore you are effectively losing some money, but this process is subtle.
I might be nitpicking a little bit there. However, once you buy solar panels, it is going to last around 25 to 30 years. You get this many years of electricity service (almost) free of charge! Who wouldn’t want that.
Best For Your Batteries
If you have the budget, I suggest you buy solar batteries, as these batteries together with solar panels will make a great couple. That is not to say regular batteries aren’t any good. In fact, using solar panels is a great way to charge your batteries.
Silence is always key to a nice and zen trip with your family. Solar panels produce no sound at all, so you can enjoy yourself without ever having to hear constant loud thuds that can even make the floor of your RV rumble, the kind of sound that power generators make.
Sure, you can always turn off the power generator, but when summer comes around the corner, the heat is going to drive everyone crazy, and an air conditioner will be absolutely indispensable if you want to take a nap without sweating profusely.
The solar panels are the way to go, they are silent yet powerful (enough for some small ACs) and won’t take away your peaceful time in bed.
If you have ever used a power generator before, then you know the hazards that come with it. In my country, there have been quite a few cases of unwanted deaths involving the power generators. A quick web browsing session can give you all you need to know about safety precautions regarding the use of power generators.
Power generators (especially gas generators) can make the carbon monoxide levels shoot through the roofs whenever it is used. Propane generators are preferred to gas and diesel generators in this respect. High levels of carbon monoxide are guaranteed to kill you swiftly (though painlessly).
It is one of the prominent ingredients of a cigarette, but in the generator’s case, we are talking thousands of times the amount. A reasonable alternative would be, you guessed it, a solar power system.
Here we talk about the characteristics of solar energy. Along with wind, biomass and hydroelectric energy, solar energy is renewable and very clean. It is clean in the sense that electricity is being generated from sunlight alone, and gives off absolutely no substance that can potentially pollute the environment.
Generators emit burnt hydrocarbons, oxides of nitrogen and sometimes, unburnt hydrocarbons are released into the environment as well, packing even more of a punch as a pollutant.
Better for the Environment
Like we have stated above, solar panels are generally the better choice in many categories compared to power generators, except maybe price. Yet another advantage of the solar system that puts it above generators is the environmentally friendliness.
Solar cells transform sunlight into electricity, very straightforward, while generators require fuels that aren’t renewable, and also produce harmful chemicals along with the electricity.
More Neighbor Friendly
When you are in an RV park, things should be quiet and contained inside each household (as expected of well-mannered individuals), so your neighbors shouldn’t bother you and you shouldn’t annoy them either.
That includes keeping noise levels to a minimum. Power generators aren’t up to the challenge. They will just bombard the surroundings with noise.
It is obvious that solar panels should be fully automatic, since they are the ones responsible for generating the electricity in the first place. RV power generators are automatic as well, but you have to manually feed them their respective fuels, normally: gas, diesel or propane.
However, you don’t necessarily have to watch over these generators all the time. Power generators can run for weeks on end without refueling.
For RVs with built-in generators, the generator only functions when you turn it on, but you can totally configure it so that it turns on automatically. In the end, solar panels win. When you don’t need them, you just have to cover the panels with a special type of blanket, called the solar blanket. This will cost you anywhere from $75 to $225.
Solar panels are trustworthy devices, and constantly give you energy whenever there is sunlight. What about the maintenance requirements? After all, maintenance is one of the things that owners dread the most when dealing with electronics.
Fortunately for everyone, solar panels need minimal checkup and maintenance, and you don’t even have to clean them very often.
It is suggested that you keep to the plan of: 1 inspection per year (hire a professional), clean your panels twice a year (you can even skip one if you live in a rainy region), and finally, schedule maintenance when needed.
There are signs that show when your solar panels need maintenance, however, mainly there is one major indicator: when you notice a reduction in output energy or that your electricity bills have increased. This rarely happens, most of the time, a little bit of cleaning will simply do the trick.
Note: Generally speaking, solar panels deliver an assortment of benefits to RV owners. Nonetheless, to ensure that you don’t get caught off guard as you use solar systems, you must keep in mind the following issues:
- Price of components is steep
- Assembly is necessary
- Occasional fluctuations in the power output
- Space restrictions for arrays and battery banks
How many RV solar panels do you need?
In order to know how many solar panels or more importantly, how much power you will be providing your RV, we have several things to consider.
In particular, you will need to find out the answers to these questions: how many watt-hours do you use each day? How much energy do your solar panels provide your batteries? In other words, you will have to try and figure out the amount of energy used and energy stored.
If you can find out the answers to these questions, it will undoubtedly mean that your system is optimized (given that you can install enough solar panels on your RV).
Surely, we can’t all be electricians, so it is advisable that you search for an entire article on how to calculate these figures. With that said, there is a method that can help you roughly balance these two sides of the scale, the load and the generation.
First, you have to calculate how much energy you use everyday. Using a little bit of elementary math, particularly addition and multiplication, we can easily (in terms of calculation) arrive at the estimate for this number.
Just try to learn how much watts each one of your appliances consume and multiply that by the respective hours of consumption, finally add all the numbers together.
Since this is a pretty easy method, I won’t be giving examples. However, calculating by hand can lead to errors, but a rough estimate is invaluable if you don’t have an RV yet.
From finding out the number of watt hours you need when boondocking, you can estimate the number of solar panels for your RV.
Another way to achieve the desired results, is to install a battery monitor. From the name alone, you can make out what it does. It will do the job of measuring the amount of energy that your battery will be using. I highly recommend buying the Victron BMV-712 battery monitor.
After installing this, charge the batteries fully and turn the charger off. After that, run your RV and keep track of the time it takes for the battery power level to reach 50% for lead-acid or 20% for lithium. Take the AmpHours (Ah) reading on the battery monitor and multiply it by the system’s nominal voltage, the result will be in Watts (for example, 1000Ah x 12.6V=12600 Watts).
That will be directly proportional with the amount of time you use your RV. Using the amount of time I asked you to keep track of, multiply it up to find the amount you need for 24h.
Finding out the energy need for your RV is tough enough, but estimating the number of solar panels you will be using might be even harder.
A method to roughly estimate this is that a 100 watt solar panel will produce from 280 to 450 Wh per day. Using the number that you got above, divide it by 280 to find the upper bound and 450 to find the lower bound for the number of solar panels you will need. This is, again, a very brief estimate
Types of Solar Panel for RV
There are 4 common types of solar panels for RV, namely monocrystalline, polycrystalline, amorphous (thin-film) and CIGS. The relative usefulness of each of these 4 compared to one another is akin to that of diesel and gasoline fuels.
Monocrystalline solar panels
Designed with the purest of silicon, monocrystalline panels are the most efficient, in that they generate the most energy from the same amount of sunlight at a time that the others. In other words, this type of solar panel has the highest conversion rate at the moment. This is, however, the most expensive type of solar panel you can buy.
Polycrystalline solar panels
Polycrystalline solar panels are less efficient in comparison, but it is a good choice considering its durability and reliability.
Packing blue rectangular cells made from raw silicon, polycrystalline solar panels reach the market at reasonable prices. Because of that, models of the type prove popular among cost-conscious RVers.
Also, with mediocre temperature tolerance, solar panels that integrate polycrystalline cannot handle extreme heat.
Thin-film solar panels
After that, we have a very interesting type of solar panels called the amorphous panels. What makes this newer type of solar panels stand out is its bending capabilities, which makes installing them much easier than before.
It is the cheapest in terms of dollars per watts, but isn’t up there with its counterparts in efficiency.
CIGS Solar Panels
While they have some of the characteristics of thin-film solar panels, CIGS (Copper Indium Gallium Selenide) solar panels have superior conversion rates.
Thus, with models of the type, it’s possible to save money as well as space at the same time. In addition to that, CIGS solar panels contain less cadmium than other types of solar panels on the market. If you care about your health, you should add these solar panels to your shortlist.

Have used product for 3 years now, camping in a motorhome off the grid. I camp 60 days/year, in Nevada, where the sun is powerful year around. I no longer use the generator. System charges 4 deep cycle batteries (two are 6=volt) easily during the day, and I use (waste) plenty of electricity at night (stereo/computer/flat screen/chargers/ lights) because the unit has now paid for itself, solar power is absolutely free. The different batteries (gel/hybrid/ dual purpose) charge at their designated rate, as keyed into the system or automatically sensed. I rave about this portable system because it is simple, efficient, and does the job, with no errors or breakdowns. Please know I am rough on camping gear, that’s a fact. I have one complaint: I noticed right off that the extension cable connectors and the battery clamp connectors were weak (where the wire meets the connector) and the wires fray and eventually break off. I’m replacing them right now with stronger battery clamp connectors and also bought heavy duty home dryer (110V) plug-ins (polarity correct) that should last my lifetime. Note: I often leave the system plugged in overnight to batteries, and it does not drain them at all. I totally recommend this system, it is a marriage made in heaven, perfect, for RV use. That’s about it.Shared by Freedom Rich

We live full-time in a travel trailer and while in Florida (we’re Canadians) we sometimes dry camp at free sites. Our first attempt was miserable as our battery didn’t last long enough to support the fridge so we had to keep running the truck about every 10 hours to replenish the battery and we didn’t use any lights, etc.
Now with the solar panel life is good. Our battery charges up completely in a few hours when it’s sunny. We have our water pump on all day, run the water heater and use all the lights we need in the evening. We even can run the furnace in the morning to warm up the rig. We LOVE our panel and it is sufficient for our needs. If we had a second battery, it would be able to charge it too,Shared by J Phillips

We have a Roadtrek class B motorhome with a single house battery. Class B’s are easy enough to drive and park that we use it as a sight-seeing vehicle, as well as camping in it. All that driving keeps the battery nicely charged. When we do stop for extended periods we can get as much as 3 days out of the batter. Any longer and we need a charge. That led me to looking into solar. Permanent roof top was an option, but was overkill for out application and more money than I’m willing to spend. Space is at a premium in our little motorhome, so I looked at the “suitcase” models. I like that this one has metal legs and a 5M(eter) cord. Our battery is tucked away behind a panel, so I made another connector using ring terminals. I’ve bolted it directly to the battery. The connector hangs down and is easily accessible.
We used it for the first time last week for 5 days. It did a great job of keeping our house battery fully charged and allowed us to use the roof mounted fan on “high” during very hot weather. It kept the lights burning bright and we were everybody’s favorite neighbors for charging phones and Kindles. We had charging voltage when ever we aimed it at the sun, even when the sky was overcast.
All of the hardware is high quality. Corner protectors all the way around, stout aluminum legs, automotive grade connectors, and a very nice carrying case. I bring the battery clamp connector with, just in case we need to charge a chassis batter. The Acopower 100 Watt folding panel fits our needs perfectly.Shared PhillG

What to Consider When Buying RV Solar Panels
If your solar panel kit has an inverter with it, that would be very nice. Most likely what you will receive in a solar panel kit is the solar inverter dedicated to the use of that particular solar panel. There are actually 3 types of inverters: micro-inverters (grid-tie), string inverters (grid-tie), and hybrid inverters (off-grid).
Micro-inverters are, as the name suggests, tiny. One micro-inverter can monitor at least one solar panel. This kind of inverter is beneficial in that it minimizes energy loss from shading, and maximizes the solar energy output of the solar panels. Due to its nature, you can easily add another solar panel to your system. For these reasons, micro-inverters are solely recommended for solar energy production in homes and RVs.
String inverters are less durable, but easier to install and cheaper. Another advantage of string inverters lies in their superiority in converting DC to AC, which is more efficient.
Hybrid off-grid inverters are basically string inverters, but are more versatile and have some more features, such as a battery charger and smart energy management systems. Like string inverters, this one is easy to set up.
Even better, aside from consuming directly (via plugging), solar electricity can be dispatched to the utility grid any time. This one is more expensive than regular string inverters, but less expensive than micro-inverters.
As I mentioned above, there are three types of solar panels which differ from one another in terms of efficiency. Monocrystalline is definitely on the top, while polycrystalline ranks in the middle, and amorphous solar panels take the last spot.
Definitely go for the monocrystalline panels if you have enough money in hand. In the long run, it just beats out the others in terms of giving the best bang for one’s buck.
If you are planning to install solar panels on the roof, you and your electrician will have to discuss the positions on which individual panels go. It is best that you have rough calculations ready before you buy the RV solar kit (or even consider buying one at all).
Make sure you have space for at least 4 or 5 solar panels. Most people install 100 Watt or 200 Watt solar panels on their roofs. Dimensions for a Renogy 100 Watt 12 volts Monocrystalline solar panel is the following: 42.2 x 19.6 x 1.38 inches.
Expandability refers to the possibility of adding solar panels to your RV system when you need it. For this, I will again recommend Renogy for their expandability. There are several solar panels of other brands that allow for an expansion when you need it.
Mounting is crucial in that it will affect the solar panel’s efficiency in different seasons. There are three types of mounting: on the roof, on the ground, and there are also pole mounts. Of course, roof mounting is the most popular, since there is no frequently used space that is taken. Since they are mostly flat (unless you use a tilter), it should be able to take in most of the sunlight in all seasons. They are really affordable, too.
Ground mounting is obviously not the choice for RVs since they must be fixed on the ground. The final type of mounting is pole mounting, this is also a rigid type of mounting, so you won’t be moving them anywhere. With that said, you can only have either portable solar panels, or roof mounted systems. Depending on different seasons, you can purchase a tilter for better exposure to sunlight.
You can definitely go with your available RV battery, buy solar batteries which come with solar kits are the way to go. If you want to change your battery banks, I would recommend Renogy Deep Cycle charger 12V or Interstate 12V Deep Cycle rechargeable batteries.
Just make sure you pick the deep cycle battery chargers, it will keep the energy much longer than regular battery charger.
Charge Controller Type
There are two types of charge controller most common with solar systems: pulse width modulation and maximum power point tracking (MPPT).
The idea is to effectively control the energy output by the solar panels in order to keep the battery charge levels at the maximum without overcharging them, while also keeping the batteries’ temperature in check.
Deciding between these two types involves considering these factors: temperature conditions, array to load ratio, size of the system, type of solar module, cost.
The best RV solar kits aren’t necessarily affordable. I must say, in any circumstances, installing solar systems is quite the investment. A 100 Watt 12 Volt RV solar kit for beginners is already upwards of $200. Large rig owners will need to buy at least a 400 Watt kit, which can be almost $800 for a fully featured product.
In exchange for buying from a renowned brand, your RV will be equipped with the most sustainable electricity-generating system for year-round usage, and you virtually don’t need to buy anything else. No need for any more hookups, you and your family can live off-grid for as long as you need to.
The best solar panels for RV roof (full kits) for me are the following:
- ECO-WORTHY 200 Watt Monocrystalline solar panel complete RV kit
- KOMAES Polycrystalline Solar panels for RV complete kit
- Renogy 400W Monocrystalline kit
Best RV Solar Panel Brands
With so many brands making solar panels for campers, RVers don’t have to worry about running out of options. That being said, if you care about reputability, you should keep an eye out for models from the following names.
Regarded by various RV solar panels reviews as one of the leading brands of solar panels, Zamp is a popular choice among modern camper owners. With the emphasis on innovation, Zamp is capable of producing solid solar panels that hold together over time.
Additionally, it’s worth pointing out that Zamp releases its models in all shapes and sizes as well. Thus, no matter what type of vehicle you own, you could find a number of Zamp solar panels that fit it.
Being a long-established brand with plenty of experience, Renogy knows what RVers expect from solar panels in the outdoors. As a result, Renogy models receive a lot of compliments from those who desire no-nonsense solar systems.
Aside from that, Renogy releases solar panels across the price points which is advantageous. If you plan to build a big solar system, you won’t go wrong with Renogy.
Thanks to the user-oriented approach, WindyNation as well as its models achieve high scores in terms of convenience. On average, it takes RVing enthusiasts mere moments to get solar panels of WindyNation up and running.
Moreover, the maintenance of WindyNation models is a straightforward affair that involves minimal time and effort. Therefore, if you don’t have the patience to look after maintenance-intensive stuff, you would come to like solar panels from WindyNation.
By investing heavily in optimization, HQST could put together robust solar panels that operate well in challenging conditions. Assuming that the RVers nail the setup process, HQST models should be able to handle everything that the outdoors throws at them.
Despite the lack of fancy features, solar panels made by Eco-Worthy still give a good account of themselves for most of the time.
Models from Eco-Worthy reach the market at reasonable prices too, hence, they match the shipping budget of typical camper owners.
Unlike many of its competitors, ACOPower dedicates its attention to making space-saving solar panels with good handling characteristics.
Needless to say, models from ACOPower not only conserve space on the top of RV but also require little work to set up.
Don’t want to spend all day positioning unwieldy and cumbersome solar panels on the crowded roof of your rig? Then it’s strongly recommended that you opt for ACOPower.
Able to generate electricity even in less than ideal weather, solar panels from RICH SOLAR could charge batteries consistently on the road.
Furthermore, owing to the the affordable nature of RICH SOLAR models, squeezing them to the spending plan is a piece of cake.
RV Solar System Components
In order to get the energy all the way from the sun into your RV and powering all your electrical appliances, you will need more than just solar panels. An RV solar system is not very hard to install, but you have to make sure you have all the components.
The good news is, for beginners, there are solar panel products that come with some or all of these components. You should definitely opt for these products if it is your first time buying.
A battery bank stores the energy that is generated from the RV solar panels. When you buy a solar kit for your RV, they always come with a solar battery. It is best that you use these solar batteries, since they are much more efficient than the average batteries.
These batteries have deep cycle recharge, which guarantees that the energy will be retained for a longer period of time. This is particularly useful since regular batteries will deplete their energy really quickly when used.
RV Solar Panels
Throughout the majority of this article, we have been talking about solar panels, and this is no doubt the most valuable player (MVP) of this system. It is the component that gives the system the name “solar”. Without its ability to harness the power of the sun, there would be no appeal at all in buying a solar system.
You can use residential solar panels on your RVs, but it is normally too enormous to fit on the roof. If it can fit though, then you have saved yourself some big money.
RV solar charge controller is a very important part of any RV solar kit. Like a surge protector, a charge controller will protect the system from overcharging. Unlike smartphone batteries which can’t be overcharged, solar batteries and other car batteries can be overcharged, and believe me, it won’t end well for your battery.
Overcharging can lead to the battery bank getting overheated and an explosion might occur. You will have no choice but to replace the battery once it is damaged by overcharging. If your charge controller is damaged, then stop the solar panels from charging immediately.
An RV inverter will invert the electrical current and transform the DC current output from the solar panels into AC current. Most of the time, you can easily use an RV inverter by connecting it to the battery bank and just plug in your AC devices directly into the inverter. After that, just sit back and enjoy fresh energy coming straight from the sun.
How To Install An RV Solar Panel
Note: Once it comes to the installation of RV solar panels, “safety first” is the rule of thumb that you must keep in mind at all times.
- Before doing anything, look for safety instructions included with the solar kit
- Never touch electrically active components if the panel is exposed to light, indoor as well as outdoor.
- Only install the panels in good weather.
- Cover the panels during installation to prevent them becoming charged
- Don’t sit or step on the panels.
When you have gathered all the components of a solar system, it should be no surprise that you should go about installing it to your rig immediately.
There have been entire articles on this matter, but here we will once again recommend that if you aren’t a certified electrician, it is best that you get your rig to the professionals to install your solar panel.
If you follow the instructions on your solar kit, and only if you manage to read and understand everything that is instructed by the manufacturer, can you go DIY.
There are several steps that are taken when installing RV solar panels. I will walk you through this, and you should take this as a very brief introduction to installing solar panels for your RV.
Step 1: Mount your solar panels
First things first, you have to mount your solar panels, in RV’s case, on the roof. Note the shape and type of roof that you have. If your roof is curved, then flexible thin-film or amorphous panels are the better choice for aesthetics and ease of installation. A tip before installing is to place the solar blanket over the panels to prevent them from charging while you work with it.
Okay, on to the mounting. Rigid panels must be fixed to the roof using screws while flexible RV solar panels can be mounted using adhesives. The roof membrane material will determine what kind of adhesive you will have to buy. Make sure you know where the solar panels are positioned after you put them in place.
If the kit comes with mounting hardware, follow the instructions to secure the panel in place. After mounting, apply a sealant (the type of sealant depends on the roof materials) to make a water-tight seal. Screw the panels to the roof.
Step 2: Run your wiring
The most common way to run your wiring is through the refrigerator vent. With this method, you don’t have to poke holes in your RV. You will only need to run the wires from the solar panel down to the charge controller, and step 2 is done.
Step 3: Connect the charge controller
The next step involves connecting the charge controller. First thing to do is to test your wire polarity, and then mount the charge controller onto the wall as close as possible to your battery bank.
Connect the controller and the battery bank, and also connect the controller and the drop down line from step 2. It is absolutely essential that you follow the manufacturer’s recommendations by reading the instructions carefully.
Step 4: Install the inverter
The final step is to install the inverter. Connect the batteries’ positive and negative lines to the inverter. After that, connect the inverter with the RV’s electrical system/grid, and you are good to go.
It is a very fun process doing your own wiring, but things can be risky if you are not careful. Read up the instruction manual and online tutorials, watch some videos if you are a total beginner.
So, Which Is The Best RV Solar Panel?
All in all, solar panels on the markets have unique pros and cons that let them excel in particular arrangements. Still, if you like to create a solar system that you could count on in the outdoors, you won’t go wrong with Renogy 100 Watt Monocrystalline. The Renogy solar panel not only packs a high conversion rate but also holds together well over time. In addition to that, the charge controller Renogy 100 Watt Monocrystalline permits you to get the most out of your batteries.
In use, the solar panel for travel trailers made by Renogy receives a shower of praises for its handling characteristics. When a need arises, you should be able to relocate it to anywhere you like to optimize sunlight exposure. The hardware that accompanies Renogy RNG-KIT-STCS-100D-VOY20 makes it easy to harvest solar energy at a moment’s notice. Lastly, the compact nature of the Renogy solar panel saves space in the interior of RV.
If you don’t like Renogy RNG-KIT-STCS-100D-VOY20 for some reason, you should take a look at WindyNation SOK-100WP-P30L. Available at a reasonable price, the solar panel from WindyNation is a sound choice for building solar systems on a budget. Aside from SOK-100WP-P30L, it’s worth the time to check out Mighty Max MAX3550270. Designed with attention to detail, MAX3550270 guarantees a stable flow of electricity on the road.
FAQs About Solar Panels For RV
1. Are solar panels on RV worth it?
f you spend a lot of time traveling, it’s wise to invest in a solar system for your rig. As long as sunlight touches solar panels, they would keep generating electricity. With solar panels providing you with electricity, you could escape the hassle of charging batteries via generators, shore power, etc. Moreover, since solar energy is free, you don’t have to worry too much about your utility bills in the outdoors.
2. Which is the better way to power an RV: solar or generator?
This is a tough choice to be honest. However, I can tell you one thing: If you have the money, go solar. For the reasons above (in the “Are RV solar panels worth the investment?” section), I believe solar has the edge over a generator.
The reasons someone might prefer generators over solar panels is that they are cheaper to buy. However, after you get the generator, you will still have to spend money on propane, gas or diesel in order to run it. Maintenance is more frequent with generators.
For solar panels, it is pretty much a one-off investment. Another reason to buy a generator is that the energy from sunlight isn’t consistent for obvious reasons. In solar panels defense, that is what batteries are for, they store energy. Your choice of course.
3. What type of solar panel is best for RV?
As we have mentioned above, the type of solar panel that you should be aiming to get is monocrystalline. Efficiency and power capacity is the answer. Monocrystalline panels are the only ones that can get upwards of 20% in efficiency, which is the highest on the market. The reason why 20% is a respectable figure is due to the panels being capable of only absorbing light of a certain spectrum of wavelength (which is smaller than that of sunlight’s). Its blacker color also adds to its aesthetics, making its appearance another selling point of monocrystalline solar panels.
RV solar panels can also be divided into two categories: roof mounted solar panels and portable solar panels. Portable solar panels aren’t as effective as their roof-mounted counterparts. If you only plan to boondock or go camping on the weekends, then they will do just fine. The best part is, you guessed it, you don’t have to install them, just move them from place to place wherever the sun shines, connect them to the charge controller, and you are good to go.
Some of the best portable RV solar panels that we have come across are:
+ Renogy 100 Watt Eclipse Monocrystalline 20A Voyager Suitcase With Waterproof Controller
+ ECO-WORTHY 120 Watt Foldable Solar panel kit
+ Zamp Solar Legacy Series 140-Watt Portable Solar panel kit
4. How much does it cost to install solar panels on an RV?
If by “install” you mean the whole process of buying and then installing then the answer is best split into two parts. You have to buy all of the components that we discussed before, including solar panels, charge controllers, battery bank, and inverter.
If you buy an RV solar kit like that of ECO-WORTHY for example, then the cost will be cut and you get the whole bundle. A 400W 12V system will cost you $550 whereas buying separately can cost you $200 more. Larger setups can cost you up to $2,000. This is ideal for heavy-duty usage. The cost of actually installing these solar panels varies between states and is a small fraction of the cost of the kit, but it can be free of charge if you do it yourself.
5. How often do solar panels need to be replaced?
Solar panels last a very long time, on average from 25 to 30 years. So if you are asking how often do solar panels need to be replaced, then the answer is “not very often”. However, these panels certainly don’t last forever, so be sure to plan out an annual maintenance and monthly cleaning routine. Still, the funny thing is, the solar panels can live long enough to eventually outlast your RV! That is some awesome durability.
6. How many watts of solar do I need on my RV?
To maintain the charge level of the battery bank at 100% alone, you need to have at least 200W. As the number of appliances that you wish to power via solar energy rises, you must increase the total watt of solar panels correspondingly. In most of the cases, 2000W is the sweet spot for rigs with typical appliances. That being said, it won’t hurt to have a bit more power than necessary as a precaution.
7. What size solar panel do I need to charge my RV battery?
For this question, you only need to buy standard RV solar panels/solar kits, they are sure to fit your RV’s roof. Just don’t buy residential solar panels, they won’t fit. Also, you will have to measure the dimensions on your roof and see how many you can fit. Do the calculations, and if there isn’t enough room on the roof, you can always go for portable alternatives.
In order to charge your RV batteries, the size doesn’t matter at all. It is the Wattage that determines whether or not it can provide enough energy for daily usage. If all else fails, you can always rely on generators to charge your batteries in tandem with solar panels. There are just too many options here.
8. Do you need an inverter for RV solar panels?
The answer is definitely yes, since the electricity that is produced by the solar panels is direct current (DC), so it is a no-brainer that you will need an inverter, considering that almost all the appliances in the modern home are AC-powered. The reason alternating current is used more often than direct current is that it is more efficient. The energy loss by DC is much higher due to the resistance of the conductor (the transmission lines), for that reason AC is preferred.
After reading this, we hope that you will have gotten a little more understanding of the best RV solar panels that you can install on your family’s RV. Decisions get harder when it comes to money, especially extravagant devices such as solar panels. After all, there is a reason the majority of the population haven’t switched to using solar yet. Trust me, after you have gotten them for a while, you will come to appreciate its usefulness.
9. Can solar panels power an RV air conditioner?
The answer is yes. Solar panels can definitely power RV air conditioners, but only just. Technically, you would need more solar panels than usual, and even then, you will still have to cut down usage of other electrical appliances for prolonged usage of air conditioners.
10. How many solar panels do I need to run a refrigerator?
To run a mini fridge on solar energy, you need between one and two solar panels. In the case that you like to run a full-sized fridge, you should include around four solar panels in your solar system. It’s possible to deduce the number of solar panels by checking out the ratings of your fridge. When you know the ampere and voltage, it’s easy to calculate wattage.
