Solar power usually is associated with a sense of high-tec. In reality, it is quite simple and appropriate technology. A solar power system consists of solar panels, batteries and a charge controller. Daylight that strikes the solar panel, will be converted into electricity directly. The more light, the more power. By storing the power in a battery, it is also after sunset available.

This device takes care of the battery: Not too full charged (switching off the solar panels) and not too deep discharged (switching off the appliances). The battery provides direct current (DC). By means of an inverter the system also provides alternate current (AC).
