Solar Photo Voltaic was such a great system!
The easiest micro-generation system to install.
A Solar Photo Voltaic (Solar PV) array is a micro-generation system that
gathers light energy and converts it into electrical direct current (DC) which
can be put to a variety of uses. The most common of these is to generate a
230 Volt 50 Hertz supply to be fed back into the electrical grid system as a
renewable energy source via an inverter which converts DC into AC.
