HOW SOLAR WORKS?
We know that solar energy is the enormous source of power supplied by the sun over 4 billion years. The extensive research conducted on solar power conclude that “the amount of solar radiation striking the earth over a three-day period is equivalent to the energy stored in all fossil energy sources.” The energy produced by the sun in one minute meets the earth’s requirement of the same in one year. In fact, the solar energy produced in a day will suffice for the power consumption of the world population for 27 years.
How do Solar Panels work?
In the solar power generation process, the sunlight is converted into electricity. This electricity is used to power your home and the excess electricity is fed into your grid-which generates revenue for you. The main components for the entire process are the solar panels and Inverters.
“A solar cell is an electronic device which directly converts sunlight into electricity. Light shining on the solar cell produces both a current and a voltage to generate electric power. This process requires firstly, a material in which the absorption of light raises an electron to a higher energy state, and secondly, the movement of this higher energy electron from the solar cell into an external circuit. The electron then dissipates its energy in the external circuit and returns to the solar cell. A variety of materials and processes can potentially satisfy the requirements for photovoltaic energy conversion, but in practice nearly all photovoltaic energy conversion uses semiconductor materials in the form of a p-n junction.” A collection of solar cells constitutes a solar panel and the packs of panels are instrumental in converting solar power into electricity.
- The Solar panels converts the photons in sunlight into Direct Current.
- This Direct Current flows into the inverter and gets converted to Alternating Current.
- Alternating Current passes through the AC isolators to the distribution box to energize home appliances.
- Meanwhile the unused electricity is fed back into the grid for feed in tariff.
