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 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 building although they can also be placed on the ground when a suitable roof is not available.

A device called an inverter changes the DC 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 low maintenance and only require regular cleaning.

Every MCS approved solar panel has a 20 year minimum power output, although not all panels will perform the same over this time. Thanks to their patented Maxeon cell technology, SunPower modules will outperform all other PV modules and are warrantied to generate 92% of year one electricity after a 25 year period.

It’s a fact that 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
