How It Works

How Solar PV Works

Solar energy is created by UV light shining on to a solar PV (photovoltaic) panel. Solar panels are made from semi-conductive material (often silicon) with a glass casing. When solar panels are exposed to energy from the sunlight called ‘photons’, it releases electrons. The electrical charges within the PV cells in the panel move and create a flow of electricity.

This direct current (DC) of electricity passes through the system’s inverter and it is changed to an alternating current (AC). AC electricity is the same electrical current used in a normal domestic plug socket. This current of electricity created by the solar panel can either be used immediately as a constant flow of electricity, or any excess can be stored in a battery for later use.

The UV light does not need to be full sunshine. UV light can be converted to energy even on a cloudy, winter’s day. Battery storage enables electricity created by the solar panels to be stored for times when electrical output is high and current is lower. Battery storage can be extended as necessary to meet growing needs.

We pride ourselves on taking our customers totally off-grid, using battery storage for times when output exceeds the solar panels’ supply. This results in extremely low-cost (or free) energy and is great for the environment. However, we also provide solar energy systems that work alongside an on-grid electricity supply, using solar energy in real time and then using on-grid electricity instead of battery stored solar energy for when usage out-demands supply.
