How Solar PV Works

When exposed to daylight Solar Panel systems capture the suns energy using photovoltaic cells. These cells don't need direct sunlight to work – they can still generate some electricity on a cloudy day. The cells produce direct current (DC) which feeds into an electrical device called an inverter where it is converted into alternating current (AC) so that it can be used by the appliances within your home or business. 

The power of a PV cell is measured in kilowatts peak (kWp). That's the rate at which it generates energy at peak performance in full direct sunlight during the summer. PV cells come in a variety of sizes. Panels can be fitted on to a roof or mounted on the ground.

On Grid systems

Grid-connected photovoltaic systems are the most common type of Solar PV system as they make use of the existing mains electricity grid. The AC electricity produced is just like the power supplied by your utility company, and can go directly to power things like computers and lights.

Off Grid systems

An “off grid” or ‘stand alone’ solar PV system produces and stores power independently from the utility grid. The electricity generated by the panels is stored in a bank of large rechargeable batteries as direct current (DC).
