Best RV Solar Panels Buying Guide & FAQ

Features to Look for When Buying an RV Solar Panel Kit

RV solar panel kits are incredibly useful, so it makes sense to take a little time to ensure that you buy the best RV solar panel or panels for you and your RV. There are a number of common characteristics that you should bear in mind when conducting your research.

  • Size of your RV and its roof will have a huge impact on what RV solar panels are available to you, as well as the amount of them you can buy.
  • Efficiency. You can buy the biggest RV solar panel kits, but that does not always make them the most efficient. Look at the manufacturer details to see what amount of power their RV solar panels can create for you before purchase. Does that amount suit and cater to your power needs?
  • We discuss the type of RV solar panels that are available to purchase below, but it’s good to bear in mind which one would work for you and your budget overall.

Benefits of Using RV Solar Panels

There are countless benefits to using RV solar panels. Here are some, to name but a few.

  • It saves you money. RV solar panels can seem incredibly expensive in terms of an initial outlay. However, that money can soon be made back and then some when users have enjoyed free power courtesy of the sun for a few months.
  • They’re environmentally friendly. Solar panels do not have to burn fuel to make power, nor do they emit any waste or horrid smells that are bad for our atmosphere. They’re good to install as a green form of energy, therefore.
  • The sun won’t run out. RV solar panels will work even in Winter when the sun is that much more limited, so you can save money making your own power year round.
  • They’re easy to maintain. Once your RV solar panels are installed, they become very easy to maintain from that point onwards. This is due to the lack of moving parts within them, so there is very little to break down or go wrong. It means your initial investment could last many years, if not decades. Plus they are easy to add to, so you can create more power, simply by adding another panel – you don’t need a whole new system if you realize you need a few more Watts every month.
  • They’re great for your RV battery. Because users of RV solar panels are being less demanding of their batteries, users will find that their battery lives will increase. Some huge RV solar kit advocates proclaim that their battery has lasted almost 50 to 75% longer than they would have done without any motorhome solar panels. The result is that batteries last for up to 10 plus years when used in conjunction with RV solar systems.
  • They’re easy to use. Once they’re set up, all the hard work is done for you. From the initial installation, RV solar panel kits start generating free power for you to enjoy in your RV as and when you like it.

Types of Motorhome Solar Panels

There are three types of RV solar panel kits in the main:

  • Mono Crystalline. These RV solar systems are made from a single crystal. The smaller, individual cells are more often than not simply a very thin layer of silicon crystal.
  • Amorphous solar panels are panels of a very thin film. Again, individual cells are made of a silicon, but this time in a very thin layer. This layer is then attached to a backing material to make the final RV solar panel kits or camping solar panels.
  • Poly Crystalline. As the name suggests these types of RV solar panels are made up of several smaller crystals in cells.

The RV solar systems that are most suitable to you will depend on your needs and budget. Amorphous RV solar panel kits tend to be the most inexpensive, but they do also work pretty well too. However, they tend to be far bigger than either of the crystalline panels. Monocrystalline panels are also incredibly efficient and are best suited to those in countries or areas with low lighting. The most popular portable solar panels for RV, however, is the Polycrystalline. This is due to the amount of space these RV solar panels take up. They can sometimes be half the size of the monocrystalline ones, yet produce almost as much power.

Camping Solar Panels Installation

Great care needs to be taken when installing RV solar panels as once they are set up properly, you shouldn’t need to tinker with them again. Each RV solar kit is different, so read over the installation instructions a couple of times, if not more, to ensure that you are setting them up correctly. However, there are a few things that should be kept in mind regardless of what RV solar systems are being used.

There are a couple of options available to those that are looking to how to install motorhome solar panels. The best recommendation is to mount the panels upon your roof so that you get the optimum sunlight possible. Otherwise, if you have portable solar panels for RV vehicles in your truck, you can place them wherever you think is best according to your location. This is perhaps the better option if you are using camping solar panels, but the positioning of them is key to get the most efficient use out of them possible.

Remember that inclining them can really help them reach their maximum usage and align them carefully so as to make the most of their ability. What can also make a big difference is any dust on the surface so keep an eye out for this. Also, ensure that all of every panel is in the sun for the best results.

Camping Solar Panels Maintenance

You can clean RV solar panel kits simply by wiping them down with a soft cloth. Make sure the cloth is clean with no nuggets of dust on the surface or particles that could scratch your RV solar panels making them less efficient.

Additionally, test your RV solar panels regularly according to the manufacturer instructions to ensure that they are working correctly at all times. It is the worst feeling in the world to have an empty battery simply because your RV solar systems are not working correctly, once you have got to your destination. Always test before you leave.

Best RV Solar Panels FAQ:

Q:  How do RV solar panels work?

A:  Using the sun to create energy and power in the form of electricity may sound like magic, but in reality, the science behind it is simply very clever. Motorhome solar panels work like all other solar panels out there and rely on sunlight hitting the panels themselves. This is why they are always put on the roofs of an RV. When the sunlight hits the RV solar panels, it is turned into an electric current. Depending on your system, this current then goes into a charge controller. This part of an RV solar kit is in charge of how much of a current goes through a batter.

The batteries included produce electricity in a DC power form and so an inverter is then used to convert it from DC to AC power for usage.

Q:  Do I have to install a battery?

A: You will always need a battery when you have installed any RV solar systems into your RV. It is what collects the power that the solar power converts from the sun’s energy. It’s often advisable to install a battery that would last three or four days without having to be charged again, as this should cover needs if a bout of bad weather is experienced.

Q:  How much solar do I need on my RV?

A:  The amount of solar power you need on your RV varies depending on your needs. In the main, each RV owner needs to determine how much power they need to figure out what size RV solar systems they need. Other considerations that need to be taken into account is simply the amount of space that is available on your RV roof. Sometimes you won’t have space for one big RV solar panel, so the best RV solar panel for you will be two smaller ones.

There are some online calculators that will help you calculate how much power you use and from there you will be able to figure out what size RV solar systems are suitable for you.

Q:  Can I run an air conditioner with solar power?

A:  Unfortunately, the answer to this is not a blanket yes. In some cases, RV air conditioner units can definitely be run using solar power. However, if you have the most basic RV solar systems installed, the answer is probably no. That being said, most RV solar kit manufacturers will maintain that their solar panels have the capacity to do so.

The reason being is that for air conditioning to run efficiently from RV solar panel kits, some modifications to the systems need to be made for them to have this capability. To make this possible, the solar power has to go through the charge controller and then into the battery bank as normal. It needs to be turned into AC for it to power the air con, so an invert is needed. Not all kits will come with an inverter.

Q:  Do I need additional hardware?

A:  It’s a good idea to buy a controller in addition to any motorhome solar panels. Controllers are great because they stop a user from charging batteries too much with the solar panel. It will stop power moving from your RV solar panels to the battery if needed.

Additionally, it’s a good idea to buy an inverter as part of your total RV solar systems. It allows you to use as many of your appliances as possible from the energy generated from your RV solar kit. This is because sometimes there will be a difference between the voltage that your battery provides and the voltage your appliances need. A power inverter is able to take care of this problem.
