Solar energy is a type of renewable energy, meaning the energy (in this case electricity) is derived from a source that never runs out – that big Sun. Renewable energy is not only less intrusive to the planet in how it is generated but it also produces lower CO2 emissions than traditional energy generation methods. Solar power is described generally as the conversion of sunlight into electricity. Photovoltaic (PV) is the field of technology and research related to the application of solar cells for energy by converting sun energy (sunlight, including sun ultra violet radiation) directly into electricity. Due to the growing demand for clean sources of energy, the manufacturing of solar cells and photovoltaic arrays has expanded dramatically in recent years.
HOW SOLAR PHOTOVOLTAIC POWER PLANT WORKS ?
Solar Panel
Solar Photovoltaic (PV) panels are generally fitted on the roof in a northerly direction and at an angle to maximize the amount of sunlight that hits the panels. Energy from the sun enters into the panels silicon wafers and generates electricity all year around Panels are connected together in a string and then cabled back to an inverter.
Inverter
The inverter converts low voltage DC electricity into the AC electricity needed to supply power for standard appliances. It comes with the digital output display to provide statistical information on power generated.
Meter
This new digital meter will allow you and your provider to read the amount of excess power you generate. You will also have access to off-peak power rates for saving your money.
Electric grid
When you generate more power with solar panels than you use in house, the excess will be purchased back by your electricity retailer. Further Feed-in incentives are likely to be offered in the future.
