Solar Panels (Solar PV)

Power your home with free solar energy

Solar panels (also known as Solar PV) capture the sun's energy and convert it into electricity to power household appliances (and renewable heating systems like Ground Source Heat Pumps). Solar panels don't need direct sunlight to work - they can still generate electricity on a cloudy day. Plus, you can sell unused electricity back to the national grid, use it to heat water in a tank (for later use), or store it for use at night. If you are a homeownerself-builder or industry professional then we can you plan, design and install solar panels and other renewable technologies.

Advantages of Solar Panels

  • Cheap – the electricity generated by solar panels is free and any excess can be sold back to the national grid.
  • Efficient – power your air, ground or water source heat pump system – improving efficiency and reducing costs even more.
  • Green – once installed, solar panels do not use any fossil fuels to function.
  • Low maintenance – solar panels last for over 20 years, with minimal maintenance.

Frequently asked questions

How much electricity will I generate?

Generally, a 4kWp system generates around 3,800-kilowatt hours of electricity a year in the south of England – roughly equivalent to a typical household’s electricity needs. It depends on a number of factors so we could only give you an accurate estimate by performing a site survey.

What size do Solar PV Panels come in?

The physical size of a system is often determined by the available roof space or the energy requirement of the property. To give you an idea, a standard 1kWp array will occupy at least 8m² of the roof.

Where can I place my Solar Panels?

The roof of a building is usually best for solar panels. Flat roofs are not ideal as it is hard to make them watertight. South facing roofs tend to be best but East-West split systems can also be designed.

My roof is in poor condition – can I still install a Solar PV system on it?

Solar PV systems are not normally heavy enough to cause structural problems. If your roof is in poor condition we would recommend getting a structural survey before installing solar panels. If it needs repairing or replacing then it would probably work out cheaper to combine this work with your solar panel installation.

I have no access to my loft – will that be a problem?

Not always. Inverters generate a lot of heat so should not be kept in a cupboard or enclosed space because of the fire risk. Lofts are a good place to store them because of their ventilation, but if you do not have access to your loft, we can help you find another well-ventilated are in your home to store the inverter.

What is the life expectancy of a Solar Panel system?

Twenty years or more, depending on the location of the installation. All of the equipment we install comes with a long guarantee.
