Solar PV Electricity Panels

Talk to Logic about getting Solar PV in Cumbria, the most affordable renewable energy generating system. It uses photovoltaic modules on the roof of a building to convert light into electricity.

How does Solar PV work?

The power produced by a Solar PV system contributes directly to the electrical demand of the building and in grid-connected installations substitutes electricity that would otherwise have been drawn from the National Grid.

Fitting a Solar Photovoltaic (PV) system gives a domestic or commercial building its very own roof-top power station, simultaneously reducing electricity bills and carbon emissions!

Solar Photovoltaic (PV) Systems use energy from sunlight and convert it to zero carbon electricity. Most systems comprise two main components:

  • Solar PV Panels (also know as PV modules) are the fundamental elements of a solar PV system. These panels contain a series of photovoltaic cells made from an efficient semi-conductor material (usually silicon based) which convert light into electricity. To yield a desired electrical power output (measured in Watts) a number of panels are connected together to form a PV ‘array’.
  • The DC/AC Inverter converts the direct current (DC) electricity generated by the panels into alternating current (AC) electricity that you can directly use as it matches the building's mains electrical grid supply. If the building is not grid connected, the inverter is usually substituted with a battery bank to store the solar electricity generated.

If at any point more electricity is being generated than the building is using, the excess will be exported to the grid and payment can be received for this. In instances where the building is not grid connected, surplus electricity is stored in batteries.
