A solar module is made up of a group of photovoltaic cells. They consist of 2 layers of silicon wafers which become positively and negatively charged when sunlight hits them. The charge created flows through a circuit of small wires connected to the wafers.
The PV modules generate Direct Current (DC) electricity and send it to the solar power inverter. The inverter transforms the DC power from the modules into Alternating Current (AC) electricity and feeds it back to the meter, ready to be used in the house or exported back into the grid/power poles.
