The sunlight hits the photovoltaic modules and they transform this solar radiation into direct current DC. The photovoltaic modules are designed to withstand adverse weather conditions like rain, snow, hail, pollution and dust.
The modules are connected to an inverter which transforms the Direct Current into Alternating Current (AC) which is the type of electric current that most of the electric appliances use and that is transmitted through the electric grid.
If the household or building is consuming electricity during the periods of generation, the said generated electricity will supply the local loads. If not the surplus electricity will be injected into the grid and measured through a smart bidirectional meter (Net-metering) which keeps track of both the electricity going into and out of the utility grid.
At the end of the month the user will only pay the difference between the consumed and the injected kWh’s.
