Electric vehicles are a good example of where access to electricity can be limited. The batteries of today’s electric vehicles must be maintained at a specific temperature in order to maximize storage capacity and their overall lifetime. What happens when an electric vehicle is left parked in the hot daytime sun? The cooling system for the battery system will be drawing energy from the same battery it’s trying to cool! In some cases, this could result in a catastrophic discharging of the vehicle’s battery, destroying the battery. Why not integrate some flexible solar film into the roof of the electric vehicle and solve this problem? A car rooftop can hold one to two square meters of solar material. Using Alta’s gallium-arsenide technology, flexible sheets of solar film can be molded directly into the car’s glass roofing material. That provides over 500 watts of generation capability on the top of every car roof!
