Generate cheap, green electricity from sunlight

Solar panel electricity systems, also known as solar photovoltaics (PV), capture the sun’s energy using photovoltaic cells. These cells don’t need direct sunlight to work – they can still generate some electricity on a cloudy day. The cells convert the sunlight into electricity, which can be used to run household appliances and lighting.

The benefits of solar electricity

    • Cut your electricity bills. Sunlight is free, so once you’ve paid for the initial installation; your electricity costs will be reduced.
    • Get paid for the electricity you generate. The UK government’s Feed-in Tariff scheme pays you for the electricity you generate, even if you use it.
    • Sell electricity back to the grid. If your system is producing more electricity than you need, you can sell the surplus back to the grid through the Feed-in Tariff scheme.
    • Cut your carbon footprint. Solar electricity is green renewable energy and doesn’t release any harmful carbon dioxide or other pollutants. A typical home solar PV system could save over a tonne of carbon dioxide per year – that’s more than 30 tonnes over its lifetime.

How do solar panels (PV) cells work?

PV cells are made from layers of semi-conducting 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. Groups of cells are mounted together in panels or modules that can either be mounted on your roof or on the ground.

The power of a PV cell is measured in kilowatts peak (kWp). That’s the rate at which it generates energy at peak performance in full direct sunlight during the summer. PV cells come in a variety of shapes and sizes. Most PV systems are made up of panels that fit on top of an existing roof, but you can also fit solar tiles.

Solar tiles and slates

Solar tiles are designed to be used in place of ordinary roof tiles. A system made up of solar tiles will typically cost about twice as much as an equivalent panel system. Solar tile systems are not normally as cost-effective as panel systems, and are usually only considered where panels are not considered appropriate for aesthetic or planning reasons.

Cost and savings

England, Scotland and Wales

A 4kWp system can generate around 3,800 kilowatt hours of electricity a year in the south of England – roughly equivalent to a typical household’s electricity needs. It will save nearly two tonnes of carbon dioxide every year. A 4kWp system in Scotland can generate about 3,200 kilowatt hours of electricity a year – more than three quarters of a typical household’s electricity needs. It will save more than a tonne and a half of carbon dioxide every year.

The average domestic solar PV system is 4kWp and costs £5,000 – 8,000 (including VAT at 5 per cent).

Other factors that affect PV installation costs are:

  • The more electricity the system can generate, the more it costs but the more it could save.
  • Larger systems are usually more cost-effective than smaller systems (up to 4kWp).
  • PV panels are all about the same price per kWp, but PV tiles cost much more than a typical system made up of panels.
  • Panels built into a roof are more expensive than those that sit on top.

 

Financial support

Solar PV is eligible for Feed-in Tariffs and you will earn a tariff for each kWh of electricity generated by your system. You will also receive another tariff for each kWh of electricity you export.

Maintenance

Solar PV needs little maintenance – you’ll just need to keep the panels relatively clean and make sure trees don’t begin to overshadow them. In the UK panels that are tilted at 15° or more have the additional benefit of being cleaned by rainfall to ensure optimal performance. Debris is more likely to accumulate if you have ground mounted panels.

Once fitted, GSM Energy leave written details of any maintenance checks that you should carry out from time to time to ensure everything is working properly. This should include details of the main inverter fault signals and key trouble-shooting guidance. Keeping a close eye on your system and the amount of electricity it’s generating (alongside the weather conditions) will familiarise you with what to expect and alert you to when something might be wrong.

The panels should last 25 years or more, but the inverter is likely to need replacing some time during this period, at a current cost of about £800..

Homeowners

You may be considering designing your new home or looking to move away from Oil or LPG and GSM Energy provides a design, survey, supply and commissioning service for you that is based on the specific requirements of your property. You can decide on whether to take advantage of the installation being carried out by our teams of experienced installers or if you prefer then by a contractor of your choice, in which case GSM Energy will be on hand through to ensure a smooth installation.

Quality standards

GSM Energy are accredited by the appropriate industry standards and back by insurance for all of our installations. We are MCS accredited and abide by our quality systems to deliver consistently excellent upgrades for our customers.

Design Abilities

GSM Energy take time and care in the design process of a new heating system as it is imperative to deliver the appropriate pump kW size and type for your home and also what other factors we and you need to be consider to ensure that your heat pump performs to the highest efficiency.

Our team of technical consultants are also competent and adept in the design and specification of both solar panels (solar PV) and underfloor heating (UFH) systems and as such they will always look to explore these options for you to maximise the heating system for your home.

Personalised Consultant Support

Our customers love the approach GSM Energy use in providing you with your own consultant who will be there and known to you throughout the process. This delivers consistency in the project planning and installation stage as well as managing your aftercare. Our consultants work with an assigned technical installer, typically they will have numerous years’ experience in plumbing, electrical work and heating systems, and thereby both aware fully aware of your needs during and after the installation.

Business Owners

GSM Energy is able to supply a full turnkey operation for your premises. From a design supply and commissioning process to a complete installation we can guide you through the required process and explain the benefits of using renewable heating and generating solutions.
