SOLAR POWER - HOW IT WORKS?
SOLAR ENERGY IN SOUTH AUSTRALIA – FACTS
South Australia is leading the way in solar energy revolution in the Australian continent. Reports estimate close to 35% of the SA’s energy as being generated from solar energy. Battery Solar Solutions have contributed to this revolution with over 3000 solar panel installations in South Australian homes and businesses.
Did you know Government of South Australia offers rebates and special feed-in tariffs for solar photovoltaic systems? Now you can benefit from every kilowatt-hour of electricity generated in excess through your solar panel system.
THE SCIENCE BEHIND SOLAR ENERGY
Solar energy is a renewable form of energy generated from sun’s heat. Photovoltaic cells are used to convert this energy into electricity. Heat from the sun is converted to energy of two kinds:
- Solar energy using photovoltaic (PV) cells: Photovoltaic cells are semiconductor diodes which convert visible light directly into direct current (DC) used for generating electricity in buildings.
- Thermal energy: Thermal solar power systems function by converting sunlight into thermal heat. The heat generated from these systems can be used for heating, cooling as well as electricity production through steam turbines.
HOW ROOFTOP SOLAR PANELS WORK
Generation of electricity from your solar panels is a scientific process broken down into few simple steps:
- Solar Modules : The solar module produces direct current (DC) electricity from the sun’s rays which hit the PV cells.
- Inverter : The DC electricity from the solar panel is passed through the inverter which converts it to 240v alternating current(AC).
- Household : Now your house consumes the created energy from your solar system.
As your appliances consume this electricity, the solar power system provides more power to cover their demand. If the solar system produces more than the appliances need, then the surplus can be exported to your utility grid. The government feed-in tariffs are applicable on this export of excess electricity.
If you wish to store the excess power produced by your solar power system, a battery storage unit can be installed and connected to your solar unit. These batteries are capable of storing the excess electricity for later use. Typically, this stored power can be used during the night, thereby, eliminating your dependence on public utility providers and lowering your energy bill by upto 80%!
