solar energy: The energy in sunlight that can be captured as heat or converted into heat or electrical energy. Some people refer to wind power as a form of solar energy. The reason: Winds are driven by the variations in temperatures and the density of the air, both of which are affected by the solar heating of the air, ground and surface waters.
Solar Safe is based on the most common battery used: the car battery. These last for several years and can be recharged thoughts of times. They work in the hot. They work in the cold, in the wet, snow, wind – you name it. They are a reliable source of energy. Solar Safe then uses a solar charge to power the car battery and the rest is history.
