Solar PV

What is Solar PV and how does it work?

Solar PV Panels, are usually situated on a roof and use semi conductors to convert sunlight to produce electricity for your home.

Unlike Solar Panels which use the energy of the Sun to heat water, Solar PV (photovoltaic) converts the suns energy into electricity.

The photovoltaic panels do not require sunlight to be effective as they operate from daylight rather than sunlight specifically, although they do supply more electricity in sunnier climates. The more sun, the more electricity produced.

The photovoltaic cell is activated by light. Electricity is created by the creation of an electric field across layers of semi-conductors in the cell.

 

Benefits of Solar PV

  • Photovoltaic cells are low maintenance, but do require checking of the wiring and ensuring the Photovoltaic panels are kept clean and debris free.
  • For new build or renovations, photovoltaic installation costs will be lower as they can be incorporated with other works.
  • Photovoltaic reduces your carbon footprint.
  • Alternative energy systems can improve overall scoring for 'Energy Performance Certificates' which form a compulsory constituent of the Home Information Packs 'HIPS' which house sellers now have to compile.
  • Alternative, renewable energy systems increase the value and saleability of your property.
  • Photovoltaic panels are low noise.
  • Photovoltaic panels can be used to supplement wind energy.

 

Suitability

Solar PV cells are heavy and need a substantial structure to support them. Our new technology PV panels are lighter and easier to install.

Photovoltaic panels need to be mounted so that they are South or mainly South facing, on an area not overhang or shadowed by trees or other buildings. If they are in the shade for part of the time their output will be less.

Whilst traditionally these have been available in panels, Photovoltaic is now also available in a form which mimics traditional tiles, and also as units which can be used in the construction of conservatories where they can also provide shade.

For larger Photovoltaic installations you may require planning permission.

Our individual system design will provide you with the best options for your individual needs. We are able to design and supply 'off grid options' which can allow you to be self sufficient for electricity, heating and hot water.

 

Typical Costs

Air Source heat pumps can be supplied from £2500.

Installed system costs will vary from £3800.

Typical domestic systems are likely to use heat pumps of between 8 - 20 KW.

Integrated photovoltaic roof panels are more expensive than those which sit on the roof, with solar tiles being the most expensive, but for a new roof the cost of the PV tiles and integrated roof panels will be offset by the lower requirement for tiles or slates.
