To capture the energy of the sun you need solar panels. The photovoltaic cells in the solar panels convert sunlight to direct current (DC) power. The panels can be installed on your roof or an empty piece of land.
The solar panels are connected to an inverter. The inverter converts the DC power into alternating current (AC) power (220v/110v).
The inverter is then connected to the safety switch. With this switch you can disconnect the solar panels from the grid in the unlikely event of a calamity.
The bi-directional meter measures the surplus of produced energy injected into the grid and the consumption of the energy from the grid. The utility company provides the bi-directional meter upon request. Depending on your electricity company there might be an onetime additional fee.
*Step 4 doesn’t apply to a stand alone system with batteries, which is not connected to the electricity grid.
