Solar systems that produce electricity are known as photovoltaic, or PV, systems. The term “photovoltaics” refers to the direct conversion of light into electricity at the atomic level, using silicon semiconductor materials. The power produced in direct current, or DC. In order to be used in a building or transported via the electric grid, it has to be converted to alternating current, or AC.  This conversion is done via equipment known as inverters.
