Top 8 Picks for the Best RV Solar Kit

Best Deep Cycle RV Battery

The battery you use for your RV is an important factor. For more information on what is the best RV battery is check our blog post.

Benefits of Going Solar RV Style

The obvious benefit of going solar is that it gives you flexibility. You’re not dependent on something else to provide power to your RV. That opens up a lot of possibilities for where you put down stakes. It even makes a difference in the campground. Non-electric sites are now on the table. If your experience is like ours, they are some of the most desirable ones too. It is possible because of RV solar panels.

You can also talk about cost savings if you’re dumping fuel into a generator or paying extra for that hookup at your campsite. We also have to address the benefit that you, as an outdoorsy person, can appreciate. You’re doing your part to pay forward and reduce your carbon footprint and greenhouse gas emissions with the best solar panels for RV use.

It’s the proverbial win-win for everyone with the best portable solar panels for RV.

Sure, RV solar kits cost some serious cash. However, the things you get out of using one don’t have a monetary value. Camping is all about connecting with nature. It reduces stress and can improve your quality of life. Saving some money is the gravy.

Solar energy is environmentally friendly and does not emit harmful greenhouse gases. The best solar panels for RV allow you to charge and maintain the voltage of your battery efficiently, whether it is a single unit or a battery bank to receive more power for more RV solar panels. They will contain all the necessary components such as MC4 connectors, junction box, and monocrystalline panels for maximum output from the install.

Let those solar cells do their work, and you can reap the rewards.

The Connection Between Camping Style and Solar Power

We’d be remiss if we only posited this rosy picture of being eco-friendly with using solar power. It also has to make sense with your kind of camping. If you only take to the road once or twice a year, you have to do some serious thinking about whether it’s a viable option for you. Many factors come into play, so it’s not a cut-and-dry answer.

On the other hand, if you’re serious about your RVing, going solar is a natural segue. Not only will you save money, but you will also add to your satisfaction of making environmentally friendly choices. It’ll also bring the enjoyment of peace and quiet without a generator running all the time with the kit providing the necessary output.

The move toward solar isn’t horribly expensive if you have a smaller rig and fewer appliances, especially if they are DC instead of AC. However, it is still a part of the mix. It’s an important point to note that cost usually isn’t a significant barrier, especially if you have a smaller camper and use a portable or smaller solar panel model.

You’ll get the most value out of a solar-powered system if it will fulfill a significant portion of your energy needs. That applies to individuals who like to take longer runs off the usual power sources. You also have some additional options if you are RVing year-round or like winter camping. An RV solar kit offers options you might not otherwise have. These are all valid reasons to explore this power source. 

Parts of a Solar Power Kit

The first thing you need to consider is how solar power will fit in with your usual camping style. It’s best suited toward RVers who like to go boondocking, preferably someplace where it’s sunny most of the time with reasonably warm temperatures. Many of these kits have specific operational temp ranges that vary with the component. Some will also have other uses for an RV boat.

Nevertheless, that sounds like our kind of camping.

It’s essential to remember that elephant in the room—your battery capacity. They power your appliances, lights, and other gadgets. Solar power, your rig’s alternator, your generator, and shore power also play a role in keeping them charged at full capacity. It simply a matter of deciding which ones are suitable for a given outing. Your RV is a mini power grid with you in control.

That gives you a lot of options with all parts of the process. Your job is to make the most of them.

Using solar power allows you to bypass the other three and have it do the heavy lifting. A complete kit, therefore, includes one or more solar panels, your RV battery or batteries, a charge controller, and inverter. We will say upfront that a kit may or may not include all of them. We’ll explain each component in detail and why they matter to your solar power system.

The parts of an RV solar panel kit include:

  • RV solar panels or mono-crystalline solar panels
  • Solar controller
  • Battery or battery bank (optional)
  • Inverter for AC power

RV Solar Panel

Solar or photovoltaic (PV) panels come in three flavors: monocrystalline, polycrystalline, and thin-film or flexible. Each one has its pros and cons. The difference in efficiency and cost lies with the arrangement of the solar cells and how that translates into solar power with the MC4 connectors, junction box, and mono-crystalline solar panels.

The monocrystalline panel is made with whole silicon crystals. They have a peak efficiency of 20 percent. Because they are a single unit, they are smaller and look less obtrusive.

A polycrystalline panel, on the other hand, consists of sheets of multiple silicon crystal bits. Their peak efficiency hovers around 16 percent because of this design for solar. They are larger and more noticeable compared to the former at the same energy capacity. Hence, they are less expensive.

There are several different materials used with thin-film products to give them their flexibility. They’re also lightweight. Using the best flexible solar panels for RV on the top of your rig is more aesthetically pleasing and aerodynamic since you can shape them in the form of your roof. However, they cost more and don’t deliver the same performance as the previous two even if they do look better.

Unless you have little real estate on top of your rig, the polycrystalline products will work fine and save you some cash over the monocrystalline solar panels for an RV. If you’re in doubt, measure your roof to make sure you’re getting the right size for the best RV solar panels.

The most common type of solar panels for RVs are 100 watts, although you will see products with higher or lower capacities. This size works well with most RVs. It’s also the most economical. After all, you can only tap your batteries so much where extra power generation isn’t going to make a difference. We’ll discuss how all of these components all come together later.

RV Battery

You also have some choices with your battery, which will store the power that your solar cells on your PV panels capture. The typical choices are a lead-acid battery or a lithium one. While the latter is the most efficient of the two, it’s all the costliest. It will also require a different setup than what we’re discussing here.

The 12-volt, deep-cycle, lead-acid battery is a popular choice for RVing. There are several types that require varying degrees of maintenance. The chances are you’ll need more than one 12-volt or perhaps a 24- or 48-volt type if you’re running high-end electronics. The critical thing to remember with these kinds of batteries is the 50-percent rule.

That means you shouldn’t discharge them more than half to get the most life out of them. Some premium products push the limits even more. We suggest going with the manufacturer’s recommendations about the depth of discharge (DOD). Most RVs have a display with the current voltage to help you stick within these limits.

You’ll see the capacity for batteries as amp-hours (aH). That means, 1 amp current for one hour equals 1 amp-hour or 12 watts if you have a 12-volt battery. (Watts equals volts times amps.) This figure tells you how much power for how long you can get out of your battery. For example, a battery that can deliver 10 amps per hour for 10 will have a 100 aH spec, 10 amps times 10 hours.

These numbers and calculations will come together when we discuss matching the best RV solar panel kit for your coach.

Best Solar Charger for RV Battery

The solar panel charge controller is an essential part of your rig’s power grid. Its function is to ensure that the output in volts of your PV panels correlates with that of your batteries to prevent overcharging them.

There often exists a disconnect between the two components when it comes to this spec. The solar controller end of things measures it in maximum power voltage (Vmp) and is often higher than 12 volts. The charge controllers make sure they play nice even with their differing capacities.

There are two types of devices: pulse-width modulation (PWM) or maximum power point tracking (MPPT) controllers. With any energy system, there is always some loss. The MPPT type manages it better but at a price. The PWM will work well for most setups unless you go RVing year-round and could benefit from optimal performance during colder weather conditions.

Fortunately, many modern RVs provide this data, which makes it easier to determine the best RV solar panels for your coach. The essential thing is having a ballpark estimate from which to begin.


The solar inverter, sometimes called the converter, takes the DC output of your solar panels and switches it to AC power to run your appliances powered by 120-volt electricity. It’s also a useful device if you have DC devices and are using shore power.

You can save money if you buy a kit that includes all of these basic components. At the very least, you’ll know that they are compatible. However, there are few things about RVing that are cut-and-dried. That is, after all, the essence of the hobby.

You customize your rig for your energy needs. You might swap out different appliances for your camping style, perhaps sticking to just DC, AC, or a mix of both. That’s saying nothing about how you cook your meals and how much you depend on your RV to provide your food. Freedom is at the heart of camping and RVing. Solar power is a natural choice.

Buying Guide for the Best RV Solar System

Now that you know what you can get in a solar kit we’ll delve into the specifics of choosing one for your RV and camping style. The first step is to figure out what your power grid needs if you want to use the system for your primary energy source.

It involves a bit of math, but we promise to make it easy.

RV in the desert with solar panels

Matching Your RV Solar Kit with Your Rig and Usage

The first question you probably have is how many watts of solar do you need on your RV? Which brand will deliver it most efficiently? Renogy? WindyNation? Another brand?

Let’s begin with the PV panel since it’s the business end of the operation. The key spec is the wattage. You’ll find a wide range from trickle-charge units to manage your batteries during the off-season to full-blown kits for boondocking for long stretches—and everything in between!

Your goal is to balance the energy coming in from the solar kit versus what’s going out from using the stuff inside of your coach, powered by your battery.

Sounds simple, doesn’t it?

Let’s start with the easy one with a quick-and-dirty approach to arriving at a figure. That means finding out how much you use on the typical camping trip. You’ll need your RV batteries charged to full capacity. Then, take it to the road. Then, you find a place to camp for a few days.

The hitch is that you’re not going to use any power at all. That means no generator, no hookup at your camping site, and no alternator charging from driving your RV. You’re going to rely totally on the juice in your batteries, so you will need to know the amp-hour capacity. Don’t do anything different from what you normally do. That’s essential to getting this baseline figure.

Monitor your batteries’ voltage until it gets to the critical tipping point of 50 percent or about 12.1 volts. Bear in mind that the typical figure for 100 percent for the battery is usually just over 12 to start. Once you’ve noticed that you’re heading to the danger zone, note the time it took to get you there.

For example, let’s say you have a 100 aH battery. All is well for two days, then, you have to power up to avoid going below 50 percent. Doing the math, that means you used about 25 amps per day (100 amps minus 50 percent, divided by two for the number of days).

Now, let’s go back to our 100-watt solar panel. The essential thing to understand is that this spec is the maximum output in ideal conditions. The weather is bright and sunny without a cloud in the sky. The air is clean with no wind blowing leaves or dust. Oh, and your PV panels are spotless. The chances are that usually isn’t the case.

Your setup’s efficiency is probably less than 100 percent, which is normal with all things considered. Generally speaking, that 100-watt PV panel will deliver about 30 amps per day. For this scenario, one panel of that capacity is sufficient to get the job done with some room to spare.

Features to Look for When Shopping for the Best RV Solar Kit

Knowing what you need in a solar panel goes a long way toward getting the right product for you. It’ll also save you some cash and frustration. Some things to consider include:
  • Components included in the kit
  • Types of devices such as PV panels and controllers
  • Vmp
  • System voltage
  • System capacity
  • Mounting hardware
  • Construction
  • Installation
  • Permanent or temporary
  • Guarantees and warranties
  • Customer service and tech support
The kinds of components, as we discussed earlier, can affect the price you’ll pay dramatically. That’s why it’s essential to match your camping style with your power needs. It also gives you options for choosing one kit over another, knowing how it may affect your usage. Most RV solar kits don’t include everything you need to get started with solar power. Most often, they won’t have a battery, which isn’t a deal-breaker as long as you stay within the recommended voltage. Others might not have the controller which brings up a compatibility issue with volts and Vmp. We suggest reaching out to the manufacturer if in doubt.

System Requirements

These specs will also tell you if the solar kit is a good fit for your rig. Be sure to check the system voltage if you are running something other than the typical 12-volt battery to find out which types of solar panels you’ll need. You’ll see some standard sizes measured in watts. It’s not a precise spec. Instead, it’s a rounded number, given the varying efficiency of your RV solar panels.

The system capacity refers to the watts that the kit including the controller can handle. We’d suggest getting a product with a higher figure than what you need. That gives you the option to expand your setup if you decide to upgrade any appliances or devices in your RV.

Design and Installation

The best RV solar kit has parts that can hold up to the elements, whether you’re driving across the country or holed up at a site for several days. Products with corrosion-resistant materials like an aluminum frame are a godsend. They also can make the components lighter and easier to handle when it comes to the installation. Also, find out if it can handle snow loads if you go winter camping.

We prefer kits that are easy to install.

Sometimes, only some items can handle being outdoors. While the panels have to be outside, you may need to keep the controller protected with the weather and inside of your RV. Be sure to check the user manual carefully about the proper installation and where to put the aluminum frame.

We like it when the manufacturers make it simpler with videos that explain the process in detail. After all, doing it correctly is imperative if you’re going to depend on the kit for your power. In the middle of nowhere is not the place to find out you did something wrong. Therefore, test out your system before it becomes mission critical and right after the install.

That’s especially vital when you’re dealing with the setup as your sole power source.

Permanent Solution or Temporary Option

Now we come to another essential question in the decision to use solar energy—whether you opt for a permanent and easy installation or a temporary one that is easy to install and disassemble.

Making it permanent makes it a hands-off solution. You drill the holes and install the hardware including the mounting brackets, aluminum frame, junction box, tray cable, and MC4 connectors. The advantage is that it is a one-time thing for efficiency. Set it and forget it for an easy solution.

The disadvantage is that it can affect the aerodynamics of your ride by adding drag and thus, lower your fuel efficiency. It may add to the cost with mounting brackets and other parts included in your price. On the plus side, it can save you money if you can tap into the benefits of tilting your RV solar panels to reduce snow loads and increase its output.

A temporary unit is easy to install and take down when you hit the road again. The question of aerodynamics is moot. Many of these RV solar panels are portable or foldable so that you can install them only when you need them. That feature makes them appropriate for a wide range of camping styles.

Depending on the type, you might not see a lot of variety in price. However, it also opens up the possibility of specific uses. Some models work best as backups for trigger charging. Others will take on the task of being the sole power source. This one parameter opens up choices.

That is the greatest benefit of using solar energy for the best solar solution.

Guarantees and Warranties

Most reputable manufacturers will cover both of these bases if just for manufacturing defects. We suggest that you read the fine print when it comes to warranties. Some may require that you register the product within a certain time frame from your purchase. You may also need to hang onto your original receipt to make a claim.

Don’t forget to check the return policy carefully. Find out if both parts and labor are covered. We’d also recommend looking at the shipping and who pays the cost. Don’t set yourself up for any nasty surprises. Look into whether there are authorized service centers in your area in case you need to get something repaired.

Making the Most Out of Your RV Solar Kit

The benefits of going solar rest on balance. RV owners get it. That means having enough energy input to compensate for your output. The same things that you do at home to reduce energy costs apply for taking life on the road. The difference is that small changes have a lot more weight in an RV than they do at home.

Little things matter.

For example, switching from incandescent light bulbs to LEDs carries some significant cost savings. Your average 100-watt incandescent bulb can take an energy toll of about 876 kWh. If you swapped it out for a 16-watt LED, you’d cut that amount by over 80 percent to 14 kWh.

Do the math. This simple change will pay off with a solar-powered system.

You should also consider upgrading your appliances if they are a bit older. You may find it worthwhile to invest in an Energy Star model in a newer vintage. The savings can easily eclipse the initial cost. Solar power with an RV is probably more a game of numbers than it is in an on-grid situation, especially when you’re trying to save dollars.

We think it’s good advice in either scenario for portable solar.

Final Thoughts About the Best RV Solar Kit

If you’ve questioned whether RV solar panels are worth it, the answer is yes. It’s simply a matter of determining your energy needs and finding a kit that can handle your camping style and provide enough reliable power with some wiggle room to spare to make the most out of solar energy.

Our top pick is the Renogy 100 Watts Solar Starter Kit. The Renogy model meets all our needs for a quality product that provides reliable power. The Renogy name is well known in the industry.

There’s no denying the benefits of getting some quality time outdoors. With a solar kit, you can enjoy the peace and quiet without the hum of a generator. You also have the satisfaction of knowing that you made an eco-friendly choice to reduce your carbon footprint even when you’re camping. That fact alone makes RV solar panel kits priceless.
