Sunlight can be used to create heat or generate electrical power. This is referred to as solar energy.It is a clean form of energy production, which doesn’t pollute the environment as some other forms of energy production do. Solar Panels or photovoltaic systems are commonly used to produce solar energy. They are an easy and convenient way to save money, add value to your home and to make your contribution towards saving the environment from global warming and pollution. But how do solar energy work? Here’s a quick guide to the steps that it takes to turn sunlight into electricity using solar panels.
1.Every day, light hits the solar panels on your home’s roof with photons .Solar panels are made up of dozens of solar cells. Each solar cell within the solar panel layers is made up of electrons that jump back and forth producing direct power for the solar system when the Sun’s rays ignite with the solar panel. Naturally, the sunnier it is, the more energy is produced by the solar panels.
2. The Direct Current or (DC) power is then sent to an inverter which converts it to alternating current known as aC power.
3. The AC power travels from the inverter to your breaker box. The power from the electrical panel is then distributed to any electrical items used in your home like your television, computer, radio or toasters.
4. The computerized controller regulates and controls the system and directs any unused power back to the utility grid.
5. The grid-connected system automatically provides additional electricity from the utility company any time you need it or when solar power is not produced.
6. The flow of electricity in and out of the utility grid is measured by a utility meter.
7. When your solar system generates more electricity than your home uses (the meter on the utility meter spins left), your extra electricity is automatically sent to the utility company. The extra power that your system produced is sold back to the utility company at the same rate that it is sold to other customers. If this happens, this is when you will receive credits for the excess solar energy from your local utility company. By this link to know how big solar panel do you need.
