What do I need to start using solar power?

At its most basic, a solar power system consists of photovoltaic (PV) panels, an inverter and the wiring to connect them to each other and to the mains power. The PV panels generate DC (direct current) electricity from sunlight and the inverter converts the DC power into usable AC (alternating current) power. 

Batteries are increasingly becoming must-have elements of solar power systems too. These store the energy generated by your rooftop panels during the day for use whenever you want.
