Lately we are hearing a lot about “Clean and Green”, It’s not only a social quote to brag upon but also a responsibility of an individual to make it a reality. Among many, on of the easiest way to go Green and Clean is by making the most of Idle rooftop space. Rooftop Solar is widely used by residence, Commercial places and industries to generate electricity for their use and export the surplus to Grid.
So you’ve probably seen solar panels on rooftops all around your neighbourhood, but do you know how they actually work to generate electricity?
Photovoltaic cells, through the photovoltaic effect, absorb sunlight and generate flowing electricity. This process varies depending on the type of solar technology, but there are a few steps common across all solar photovoltaic cells.
First, light strikes a photovoltaic cell and is absorbed by the semiconducting material it is made from (usually silicon). This incoming light energy causes electrons in the silicon to be knocked loose, which will eventually become the solar electricity you can use in your home.
There are two layers of silicon used in photovoltaic cells, and each one is specially treated, or “doped”, to create an electric field, meaning one side has a net positive charge and one has a net negative charge. This electric field causes loose electrons to flow in one direction through the solar cell, generating an electrical current.
Once an electrical current is generated by loose electrons, metal plates on the sides of each solar cell collect those electrons and transfer them to wires. At this point, electrons can flow as electricity through the wiring to a solar inverter and then throughout your home.
A photovoltaic cell on its own cannot produce enough usable electricity for more than a small electronic gadget. In order to produce the amount of energy a home might need, solar cells are wired together to create solar panels, which are installed in groups to form a solar energy system.
Depending on factors like temperature, hours of sunlight, and electricity use, sanction load, property owners will need varying amounts of solar panels to produce enough energy. Regardless, installing a solar panel system will likely include several hundred solar photovoltaic cells working together to generate and electrical current.
