The step by step process of how a grid connected solar power system works;
- When sunlight hits the solar photovoltaic (PV) panels, electricity (or ‘solar energy’) is produced.
- The electricity then runs from the solar panels through an inverter.
- The inverter turns the power from direct current (DC) into alternating current (AC), which you can then use for electronic appliances in your home.
- If the appliances in your home are turned on while solar power is being produced, the power runs through the switch board and the solar power is sent to your appliances.
- Any appliances that are AC powered can use the solar power, including lights, water pump, aircon conditioned , water heater, dispenser, etc.,
- If electrical appliances are switched off, or if excess solar power is being produced, the power gets sent to the grid which is measured by the meter box. Your electricity retailer applies credits in exchange for the energy you produce. During the night, when your solar power system is not producing energy, you will draw power from the grid, which you can pay for with credits earned from exporting solar power during the day.
