Solar Electricity (PV) Panels

Solar PVSolar photovoltaic or PV panels create electricity during day light hours and contrary to popular belief they don’t need direct sunlight. They will still generate electricity on over cast days, although not as efficiently.

How do PV panels work?

PV cells are panels you can attach to your roof or walls. Each cell is made from one or two layers of semiconducting material, usually silicon. When light shines on the cell it creates an electric field across the layers. The stronger the sunshine, the more electricity is produced.

PV cells come in a variety of shapes and colours, from grey "solar tiles" that look like roof tiles to panels and transparent cells that you can use on conservatories and glass.

The strength of a PV cell is measured in kilowatt peak (kWp). That's the amount of energy the cell generates in full sunlight.

PV panels use energy from the sun to create DC (Direct Current) in a similar way to a battery.  Domestic electricity supplies are AC (alternating current) and won’t run on DC. The panels are connected to a piece of equipment called a converter which changes the DC to AC and transforms the power to three to four volts above the incoming electricity supply, which allows it to be fed back into the grid.

Electricity generated can be used to provide free power in your home or business, or you can sell it back to the grid. For all electricity you produce you will receive a payment called a Feed-in Tariff, which is guaranteed for 25 years for solar PV.

The benefits of solar electricity

  • Cut your carbon footprint: solar electricity is green, renewables energy and doesn't release any harmful carbon dioxide (CO2) or other pollutants. A typical home PV system could save over 1 tonne of COper year - that's more than 30 tonnes over its lifetime.
  • Cut your electricity bills: sunlight is free, so once you've paid for the initial installation your electricity costs will be greatly reduced. A typical home PV system can produce around 50% of the electricity a household uses in a year.
  • Sell electricity back to the Grid: if your system is producing more electricity than you need, or when you can't use it, someone else can use it - and you could make a bit of money
  • Store electricity for a cloudy day: if your home isn't connected to the national grid you can store excess electricity in batteries to use when you need it. 

Is solar electricity suitable for my home?

To tell if solar electricity is right for you, there are a few key questions to consider:

  • Do you have a sunny place to put it? You'll need a roof or wall that faces within 90 degrees of south, and isn't overshadowed by trees or buildings.If the surface is in shadow for parts of the day, your system will generate less energy.
  • Is your roof strong enough? Solar panels are not light and the roof must be strong enough to take their weight, especially if the panel is placed on top of existing tiles. If in doubt, ask a construction expert or an installer.
  • Do you need planning permission? In Scotland, England, Wales and Northern Ireland, you don't need planning permission for most home solar electricity systems, as long as they're below a certain size - but you should check with your local planning officer, especially if your home is a listed building, or is in a conservation area or World Heritage Site.
