The sun is a natural nuclear reactor and is capable of generating an infinite amount of energy. Photovoltaic (PV) modules, often known as solar panels, can harness the power of the sun’s rays and convert it to electricity, making it a clean, green source of power for everyone on the planet. The whole process is quite simple and can provide sustainable energy for years to come.
Capturing power from the sun
PV modules are grids of individual photovoltaic cells made primarily of silicon, cadmium telluride, and copper indium gallium selenide. Silicon is an excellent light absorber, capable of absorbing roughly two-thirds of the solar spectrum. Each cell is encased in aluminum and joined together to form the panel.
When UV rays strikes the solar cells, which are both positively and negatively charged, the electric field created by the sunlight causes the drifting electrons to move toward the metal plates that surround the solar cell, resulting in increased efficiency. The electric current generated by the electrons in motion is then directed into the wire system that is attached to the panels.The connected wiring system links the panels to an inverter (referred to as an array), which converts direct current (DC) to alternating current (AC) and uses the alternating current to power all electrical components in the home or business.
Modern PV modules are designed to capture UV light through cloud cover and fog while still producing enough energy to power the network. If one of the connected panels does not receive enough light, the others can work independently. An experienced installer will know where to position the panels to ensure consistent energy flow.
Grid connected systems with backup
Unused electricity is returned to the power grid via the meter, which measures the flow of electricity from the grid to the property and vice versa. When the solar energy system generates more electricity than is required, the meter runs backward, and a credit is applied. This is known as net metering, and it can significantly reduce energy bills. As a result, when more electricity is required than the solar array is producing, supplemental electricity will be drawn from the grid through the meter, causing it to operate normally. Some energy will have to be drawn from the grid, particularly at night when the solar array is not producing.
Most Floridians are required to stay connected to the power grid when the PV array is not producing, but they can certainly add a proper battery backup system, such as the Tesla Powerwall, for times when the grid may go down. ProSolar is Florida’s leading solar energy system installation company and will gladly answer any additional questions about the wonders of solar energy for any property type.
