You've probably seen calculators with solar cells -- devices that never need batteries and in some cases, don't even have an off button. My system is also fully mobile; at the end of each trip, I pack it all up which only takes a few minutes and bring it back to suburbia – so if we ever have a blackout here, I’m still able to work! There are so many variables that effect how 12v systems work, how different types of batteries behave, how the environment effects the efficiency of solar panels, all these things mean a one rule for all is pretty much impossible to come up with. Panels facing north are the least desirable but in many cases can still save homeowners money. The top layer has been specially treated so that its atoms are unstable — they have one too many electrons that they would really like to get rid of. The batteries used in a stand alone solar power system are specially designed for constant discharging and charging and if properly selected, will last for years – these are known as deep cycle batteries. Even in battery based systems, again, the batteries can be recycled as can just about everything in a solar power setup. As the sun hits the solar panels, they generate direct current (DC) electricity, where the electrons flow around a circuit in one direction. How do RV solar panels work in the first place, and which are the best kinds to get for an RV roof? They produce no carbon emissions or waste products as they convert sunlight into electricity.
