Photovoltaic solar power converts the sun’s energy into electricity. Solar cells, or photovoltaic cells, are silicon-based pieces of material that absorb the sun’s light – not warmth as in a thermal application. Solar energy excites the electrons in the solar cell and electricity is produced. Solar cells are combined in solar panels, and groups of panels are linked to produce greater power.
- Photovoltaic solar panels:The solar panels convert sunlight (not heat) into Direct Current (DC) electricity.
- Inverter:An Inverter then converts the DC electricity into 240-volt Alternating Current (AC) electricity suitable to power appliances in your house.
- Power for your home:Your home uses electricity from the solar panels first. Then, if your electricity use is higher than the supply available from the panels, your system gets the extra power from the electrical grid.
- Monitoring usage:A meter is used to monitor the electricity used from the electrical grid as well as the solar electricity your house supplies to the grid.
- Excess energy:If your solar panel system produces more electricity than you use, the excess electricity is exported to the electrical grid, and your meter spins backwards.
