A solar power system works in the following steps:
- The solar PV panels placed on roofs are made up of layers of semi-conducting material, usually silicon. When sunlight hits a solar PV module, it creates an electrical field across the layers, which then generates direct current (DC) electricity.
- The inverter then converts the DC power generated by the solar panel into stable alternating current (AC) 240V electricity.
- The bi-directional meter measures the amount of electricity that is imported and exported into the grid. Unlike old meters, the bi-directional meter has a digital display screen and can record electricity that is fed back into the grid.
- The generated electricity can then be used safely in appliances around the home.
- The energy monitor can record and show how much electricity is being consumed in real time.
- Any extra energy that is generated from the solar power system can then be exported back into the grid, and depending on the government regulations in different states in Australia, the extra electricity generated can be sold back to receive Feed-in Tariffs that will further assist in lowering electricity bills.
