Solar power usage has been on the rise in the RV community, with many RVers taking advantage of the sun to power their systems while boondocking. Where it is a no brainer to use solar in sunny states like Arizona, many RVers who live in less sunny states may wonder whether it makes sense to use solar if they live in a climate with limited sunshine.
Solar panels are designed to harness sunlight and convert it into electricity, but just because a day is cloudy, power output may not dip all the way to zero unless it’s very cloudy. Despite the reduced power production on cloudy days, solar panels can still generate electricity and contribute to meeting energy needs, especially when coupled with energy storage systems like batteries. Additionally, advancements in solar panel technology, such as improved efficiency and tolerance to low-light conditions, have helped increase the overall performance of solar panels even in less-than-ideal weather conditions. With these facts in mind, let’s look at ways RVers can make the most of solar in a climate that is not sunny all year long.
One way RVers can prepare for a climate with less sunlight is to use an energy storage system like a lithium iron phosphate battery. Compared to AGM and lead acid, iron phosphate batteries allow faster charging and deeper power draw, which gives RVers more power on cloudy days. Having a compatible power system allows RVers to store excess energy generated during sunny periods for use later when sunlight is limited. Depending on the number of solar panels and batteries installed as well as how much sun you get in the climate, you may be able to boondock comfortably in a less than sunny climate.
In addition to battery storage, RVers can optimize the power generated by the sun through the placement and tilt of rigid RV solar panels. By adjusting the angle of the panels to match the sun’s position in the sky, RVers can improve their efficiency and capture as much sunlight as possible. Tilting the panels toward the sun can help compensate for the reduced intensity of sunlight in cloudy conditions, helping RVers make the most of their solar power system. Unfortunately, this is not possible with flexible adhesive panels. As RVers stop during their travels, they need to take into consideration where they park and the direction the RV is facing to ensure the solar panel tilt gets the most sunlight.
Another strategy to ensure comfort in cloudy climates is to have alternative charging methods as a backup. While solar panels may be less effective on cloudy days, RVers can still harness other sources of energy to meet their needs. Generators (both portable and installed) can provide additional charging capacity during extended periods of inclement weather, ensuring that RVers always have access to electricity when they need it most.
Last, but not least, RVers can also benefit from energy conservation practices. In cloudy climates, it’s crucial to be mindful of energy usage and to conserve power whenever possible. This could involve using energy-efficient appliances, minimizing unnecessary electricity consumption, and maximizing natural light during the day. By adopting these practices, RVers can reduce their reliance on solar power during periods of limited sunlight.
In conclusion, while solar power may pose some challenges for RVers in less sunny climates, it remains a viable and eco-friendly option for off-grid living. By implementing strategies such as energy storage, conservation, supplementation, and panel optimization, RVers can harness the power of the sun to meet their energy needs, even when the skies are overcast. With careful planning and the right equipment, solar power can help RVers enjoy a sustainable and self-sufficient lifestyle, no matter where their travels take them.
