Domestic Solar PV Installation

With a Domestic Solar PV system you can reduce your carbon footprint while lowing your energy bills by up to 60%. Solar panels enable customers to generate their own free, green electricity that can be used within their property.

If your property has sufficient roof space to house a Solar PV system then why not invest in one today. Once the installation has been paid for then let the savings commence. Sunlight is free so why not take advantage of it and get paid for the electricity that your Solar panels generate, by selling it back to the grid and reducing your energy bill, it is a win-win investment.

Check out our FAQ page to see if your property would be ideal for a Solar PV installation.

 Benefits at a glance 

  • Reduce your carbon footprint.
  • Generating your own electricity from Solar reduces your carbon output and could offset most, if not all, of your properties' carbon emissions.
  • Reduce energy used from the grip.
  • PV sytems work in daylight, so they will generate electricity all year round.
  • Installation is quick and easy with minimal maintenance required.
  • Potentially save 100% on daytime electricity costs.

What is Solar PV?

Solar Photovoltaic (Solar PV) is a method of generating electricity by converting Solar radiation into direct current (DC) electricity. An inverter then converts the electricity to alternate current (AC) so it can be used within the business. With advances in technology the modules still generate electricity even on cloudy days.

Photovoltaic’ is a marriage of two words: ‘photo’, meaning light, and ‘voltaic’, meaning electricity. Photovoltaic technology, the term used to describe the hardware that converts Solar PV energy into usable power, generates electricity from light.

Solar PV panels

Solar PV panels will operate at maximum efficiency if they are orientated towards the south. The most efficient tilt angle can be calculated by subtracting 20° from the geographic latitude. Therefore, for an installation in London (latitude of 51°) the optimum tilt is (51 minus 20) 31° from the horizontal. A Solar PV panel installation causes minimum disruption to the home and systems can be retrofitted. A typical silicon cell is quite small, approx 100mm x 100mm square. Solar cells produce electricity at low voltage but when more power is required a number of cells can be connected together to create photovoltaic modules, or Solar PV panels.

Solar PV panels that are connected together in series are often referred to as an ‘array’. A grouping of Solar PV panels can be fitted in different configurations depending on the local conditions e.g. to follow the shape of a roof or to avoid a roof light. Solar PV panels usually have a backing sheet that is opaque but the backing can be transparent, allowing some light through and creating a dappled effect.
