Solar PV (Solar Photovoltaics) is the generation of electricity using energy from the sun. Modern solar panels produce electricity from daylight and do not require direct sunlight, although more electricity is produced on bright, sunny days.

Enough sunlight actually falls onto the earth every hour to meet the world’s power demands for an entire year, so harnessing and using this free energy can help reduce our reliance on other sources of energy and be beneficial to the environment as well. By installing Solar PV panels you can produce free, green energy for your home or business.

Solar PV panels are normally mounted on the roof of your property although they can also be placed on the ground when a suitable roof is not available.
A device called an inverter changes the electricity produced by the panels into ‘useable’ electricity that can then be used to power appliances in your home or can be fed back into the National Grid.

Solar PV panels contain no moving parts, are self cleaning and are maintenance free. The output from the panels is guaranteed by the manufacturers for 25 years. All Solar PV panels will continue to produce electricity long after their guaranteed period. This means that you will continue to benefit from free electricity even after your ‘Feed In Tarriff’period of 20 years is over. The first silicon-based PV systems were installed in the 1960’s and some of these systems are still in place and generating today!

How does solar PV work?

  1. Sun’s energy converted into DC voltage by PV panels on roof
  2. Inverter converts DC voltage into ‘useable’ AC voltage
  3. Generation meter records production
  4. Electricity generated used in household appliances during the day
  5. Unused electricity fed back into National Grid
