Solar and PV Feed in Tarrif Information

If you want to reduce your electricity bills and help to combat climate change, then take a look at Solar PV. Solar electricity systems capture free energy from the sun and convert it into electricity. You don’t need direct sunlight, you can still generate electricity on a cloudy day. 

It can produce around 40% of your home’s electricity and any excess electricity generated can be sold back to the national grid, earning you money under the Feed In Tariff.  This provides an excellent return on investment. As energy prices continue to rise, solar power helps to ‘future proof’ your home against rising costs, whilst ensuring a continual supply of electricity. 

Most PV systems have a 25 year warranty, with a life expectancy of around 50 years.  They require little or no maintenance, and continue to provide a clean, sustainable and highly efficient way of generating your own electricity over the lifespan of the system. 

For every 1kWp (kilowatt peak) installed, around 450kg of carbon dioxide emissions will be saved.  Each 1kWp should product at least 750kWh per year in the UK. The average household in the UK uses approximately 3300kWh every year, so a 2kWp system will product almost half of your yearly requirements.  Over the 25 years of the Feed In Tariff, that means around 37,500kWh of clean electricity generated and 22 tonnes of CO2 emissions saved. 

Follow our simple guide to the Feed In Tariff and see how much you can save and earn by installing a Solar PV system to your home.  To benefit from this scheme, your installer and the equipment they provide must be registered with the Microgeneration Certification Scheme (MCS). Dyson Insulations are registered MCS installers, and we work with accredited manufacturers such as Romag, Mitsubishi, Schuco and Grants.  We are also members of REAL (Renewable Energy Assurance Ltd) and REIGA (Renewable Energy Installation Guarantee Agency).

Certain conditions are required to ensure that a solar electricity system works at its highest efficiency, and if the roof of your home does not meet these conditions, then in some cases it may not be worthwhile installing.  To see whether your home is suitable for Solar PV panels, take a look at the guidelines below, which show the criteria by which we assess your roof.

 

• South facing, south east or south west.  East or west may be suitable, however performance will be less effective
• 30-40 degree angle – this is the ideal angle, however more vertical pitches may be suitable but with reduced performance from the PV unit
• Unshaded for most of the day.  Any shade from trees or neighbouring buildings can make a large impact on the performance of a PV system.
• Adequate roof space.   You will require a minimum of 8m2 roof space for each 1kWp array of Solar PV panels. 

Roof Checker

Not sure if your roof is suitable? Go to Google Earth check you have a south facing roof by looking at the compass on the top right side of the page.

Click on the ruler icon and put it on your south facing roof, click at each corner of the roof and check the measurements. Once you have the size, use our calculator below to see what size of of PV system you could install.

Take a look below to see what size system you may be able to fit on your roof.
