![]() If you permanently rely on the solar panels and don’t rent the more expensive campsites with shore power, you could recoup the cost of the panels in less than four years.Īnd you can use the solar panels to charge batteries or power equipment when you’re somewhere not designed to provide power to RVs like sports stadium parking lots. If you find that you don’t have the money to pay for a more expensive campsite with shoreline power, you have that option. You have the ability to go where you want, when you want, and still have power as long as you take the time to charge the batteries first. Or you could park in a mega-mart parking lot overnight and still have power, if you decide you don’t want to stay in the local RV park or a friend’s backyard. Depending on the RV solar panels you choose, you could take them with you on a hike so that you could recharge smart phones and laptops while you’re on the trail. ![]() You could choose to park in a spot with a better view or lower price without having to choose to give up quality of life. If you own RV solar panels, you can use it to charge devices when you’re off the grid or have access to shore power. The upside is that they are lightweight, and flexible solar panels don’t hurt your fuel economy as much as if you had solid solar panels standing up on the roof as you drive. ![]() However, the fact that you can attach them to the top of an RV via glue means you don’t need screws to mount them or have to drill holes into the top of the RV. They degrade faster, and they could be damaged more readily than sturdier panels. The downside of flexible solar panels like Copper Indium Gallium Selenide panels is their vulnerability. Their tandem design could allow for built-in devices like sensors into the film itself, though that’s not a mature technology. This creates the thinnest, lightest “thin film” solar panels possible. They have a protective buffer layer, allowing films as thin as 1 micrometer. ![]() They have the highest efficiency of any thin-film solar panel technology, beating out cadmium telluride by a modest margin. There are several benefits of CIGS solar cells over the other types of thin film solar cells. While thin film solar panels come in multiple forms, CIGS is so important it is considered its own category. So is the relative limited supply of tellurium it is about as rare as platinum. The toxicity of cadmium, though is a strike against its widespread use. It has been available for years powering devices like solar calculators.Ĭadmium telluride (CdTe) has a lower cost of manufacturing and far greater efficiency than amorphous silicon. Amorphous silicon had the lead in this market because it is based on the best-understood technology. The PV substance is most commonly amorphous silicon, cadmium telluride, copper indium gallium selenide. These solar panels are created by laying a photovoltaic substance on a solid material like glass. These solar panels are rather expensive per unit, but prices are coming down as the manufacturing process improves. If the solar panel doesn’t have a frame, you know it is a thin film solar panel. These solar panels may or may not be protected by a frame. Thin film solar panels are a very new technology. If you’re traveling somewhere with cloudy weather or parked in partial shade, a large thin film panel will outperform the first two types on our list. Conversely, they work better in low light conditions. This means you either have to have it take up far more space to get the same amount of power as crystalline silicon panels or do with less power. Thin film solar panels are much less efficient than the first two types of solar panels. There are jokes that it only lasts a year or two, though this depends on the operating conditions. If they can blame shipping or installation for the issue, you get nothing. The warranty is only for material and workmanship. And while the manufacturer says these solar panels don’t have hot spots, they do develop hot spots hot enough to melt and warp supporting structures in some circumstances. This solar panel system does not have good electrical safety features to prevent shorts and other issues from potentially escalating to a fire hazard. Assembly tools and connectors are available at extra cost from the manufacturer. The kit comes with two ten inch cables with MC4 connectors. You can use this solar panel on your boat as long as you don’t get it submerged. This solar panel has a sealed, water-proof junction box suitable for exposure to rugged, wet conditions. They weigh so little that they won’t slow down an RV the way large, heavy panels would. At four pounds, they are pretty much the only solar panels you could literally string up in a tree to generate power. They’re portable, though you can’t roll them up and stow them in a backpack.
