Solar energy takes the sun’s energy and turns it into clean electricity. Solar energy is a sustainable, carbon free form of energy production; it’s a good investment in the planet and for your home.
Photovoltaic systems use panels to collect and convert the sun’s energy into electricity. These systems can be tied into the existing electrical grid to feed energy into the grid. They produce the energy needed to meet your electricity needs, and when you aren’t using electricity your house acts like a miniature renewable energy power plant!
How Solar PV Works
Solar PV systems use cells to convert sunlight into electricity. The PV cell consists of one or two layers of a semi conducting material, usually silicon. When light shines on the cell it creates an electric field across the layers causing electricity to flow. The greater the intensity of the light, the greater the flow of electricity.
PV cells are referred to in terms of the amount of energy they generate in full sunlight; know as kilowatt peak or kWp.
The solar cell is the basic building block of Solar PV technology. Most people are familiar with PV Solar Cells that power calculators. These cells are wired together to form a module (PV solar panel)
The PV modules gather solar energy in the form of sunlight and convert it into direct current (DC) electricity. An inverter can convert this DC power into alternating current (AC power, which is the type of electricity used in your home).
PV modules are joined together to form a PV Solar Panel system. Large PV systems can be integrated into buildings to generate electricity.
