How Photovoltaic (PV) Panels Work

Advances in technology have made it far easier for the average homeowner to utilize solar energy for his/her home. Additionally, grants and tax rebates for residential solar panel installation and use has also made it financially feasible for many more homeowners to take advantage of this alternative energy. However, it can still be confusing how solar energy in Pomona works. Design Air, Inc. has installed hundreds of solar panels over the years, and we can help you become greener and save energy with solar panels for your home.

What Does “Photovoltaic” Mean?

Photovoltaics (PV) is the direct conversion of sunlight into electricity at the atomic level (atoms).

How Does PV Work?

All photovoltaic energy begins with a single mechanical cell called a solar cell. The top and bottom of the cell are treated with materials that make one side of the cell positively charged (the bottom) and the other negatively charged (the top). The top and bottom are connected by electrical conductors, and the opposite charges create an electrical field that is necessary for the solar cell to create electricity from sunlight.

How Is Electricity Generated?

When sunlight hits the solar cell, electrons are knocked loose from the atoms in the top and bottom of the solar cell. They are then captured as electrical current in the conductors that are attached to the solar cell. Metal conductive plates on the sides of the cell collect the electrons (electrical current) and transfer them to wires. At that point, the electrons (electrical current) flow like any other source of electricity.

Solar Array

Obviously a single solar cell isn’t going to power your home, but this is where the solar array, also known as a panel, comes in. Solar panels are made of multiple solar cell modules that are wired together to provide enough electricity to power your home or large systems, like your air conditioning system. PV panels produce direct current (DC) electricity and can be connected in either series or parallel electrical arrangements to produce any required voltage and current combination. The solar panels can be wired right into your home’s electrical box.

Solar energy can make your home very energy efficient and significantly lower your carbon footprint. If you are interested in seeing what solar energy in Pomona can do for you and your home, call Design Air, Inc., today and schedule an appointment with one of our installation experts.
