Solar energy, one of the renewable sources of energy, works by seizing the sun’s energy and turning it into electricity for your home or business. Solar Panels are made up of solar cells. A solar cell made of semi-conductors like silicon is the basic unit of every solar technology which directly converts solar light energy into electricity.
How does solar energy work?
The sunlight falls on the solar panels generating DC (Direct Current)s electricity
This DC electricity is delivered into a solar inverter that converts it to AC electricity.
This AC electricity is used to power appliances in your home.
Leftover electricity is fed back into the main grid.
Firstly the sunlight shines on solar panels, usually mounted and this creates DC electricity. Each solar panel is usually a string of 60-72 solar cells string together in series on your roof. In the case of a system using a string inverter then the DC power will flow down to the inverter at which point the inverter will convert this electricity into AC power in the same voltage as is used in your house.
The inverter will then feed AC power to your circuit board and this power is available to service any electrical loads within your property. If the loads in your house are greater than the power that is being supplied by the inverter then your loads may be partly met by solar power and partly by the use of grid power. With gird connect solar power systems you have the option at any time to use either solar power, grid power, or a combination of both.
In some instances you may be generating more solar power than your total electrical loads require and in this case your solar electricity will flow back out to the grid through your meter. Usually, your utility meter needs to be changed so that it can keep a separate record of what electricity you export to the grid and what you consume from the grid.
Many environmental factors such as weather, location, time of the year may influence the amount of solar energy, but it can be harvested throughout the year.
