How Solar Cells Generate Electricity

Solar powered electricity is becoming one of the newest technological terms on the market today. Various people would like to know how to power their homes through solar energy for various reasons. Some people believe that the cost to power their homes with solar energy would be cheaper on them in the long run. Still, others simply like the idea of being able to power their homes in a more environmentally-friendly manner. Whatever your reason for wanting to power your home with solar energy, you probably would like to know a little bit more about solar cells generate electricity.

Solar cells are powered by the sun, which produces solar energy. Photovoltaic cells can be equivocated to a direct current generator by the sun. When the light from the sun strikes solar cells, they knock the electrons free in the silicon crystal structure of the cells. This forces the electrons through an external circuit, such as a battery or direct DC load, and then sends them back through the other side of the solar cells to repeat the process all over again.

Approximately 0.5 voltage output is generated by a single solar cell, and the amperage output of the cell is directly proportionate with the surface area of the cell. Usually, approximately 30 to 36 solar cells are wired together to create one solar module. The way that solar cells generate electricity makes it so that each solar module produces approximately 12V of nominal output. Additional solar modules can be wired together in series and parallel with one another to create a complete solar array that can be used to charge a 12V, 24V or 48V battery bank.

The way that solar cells generate electricity can be used by homeowners and business owners to power their homes or businesses. By converting the sun’s energy into electricity, solar panels eliminate the need for traditional electricity generation, which could help reduce the cost of energy bills in the long run.
