Solar photovoltaic (PV) systems convert the energy in sunlight directly into electricity. In less windy areas, PV is often your only option to generate renewable electrical energy.

PV can be the most costly renewable energy option. However, prices are coming down, and it’s simplicity and compact size make it an attractive option if price isn’t your key consideration.

In addition to your rooftop PV panels, you’ll need space for a small inverter unit. This converts the DC electricity from the PV to your domestic AC supply.

Various types of PV modules are available. Most are made from very pure crystalline silicon. These convert 12% to 15% of incident sunlight into electricity.

Key factors in choosing Solar photovoltaics

Factors you should consider regarding photovoltaics

  • Have you already tried to minimise your electricity consumption? There isn’t much point in considering expensive PV if you haven’t.
  • Are you in the process of building your property? If so, consider using PV in place of part of your roofing or wall materials to reduce cost.
  • What’s your budget? A solar photovoltaics system typically costs £5,000 to £12,000 depending on size.
