Solar Photovoltaic (PV) systems capture the sun's energy using silicon cells.
How it works
Solar Photovoltaic (PV) systems capture the sun’s energy using silicon cells. The cells convert the sunlight into electricity, which can be used to run electrical appliances, heating & lighting both domestically & commercially.
Although sunshine is not necessary for PV panels to work, the greater the light intensity, the greater the production of electricity. All that is required is a roof or wall facing within 90 degrees of “due South” with no (or very little) shading from trees or buildings, etc.
Feed In Tariffs
The scheme, introduced on 1st April 2010, pays for all of the electricity generated, with an additional payment for any excess electricity not used and exported back to the National Grid. It is government legislation which guarantees a fixed, premium rate for renewable electricity fed into the national grid.
The rates have been cut though – is it still worth it?
Definitely! Although the Government have cut the rate paid for the FIT, Solar Panel prices have fallen over the last year which has meant that the returns are still excellent.
How does it work?
There are 3 ways to benefit from installing Solar Photovoltaic panels:
- You are paid for all the electricity you produce.
Your electricity supplier will pay you an agreed rate (1st April 2015 to 30th June 2015 it will be 4.39p for domestic systems) for every unit of electricity you produce – whether it is used or not.
- You are paid for any electricity you export back to the grid.
Any electricity you produce but do not use is fed back onto the National Grid, and your supplier will pay you an additional 4.85p for every unit you export – usually guaranteed at 50%.
- Your electricity bills are reduced.
The electricity you generate is free to use so you electricity bills will fall. This will become an ever greater benefit as fuel prices continue to rise.
The scheme is guaranteed for 20 years, is index linked to the RPI and tax-free for domestic installations.
To qualify for the FIT, the installation must be carried out by an MCS-approved installer. Stratford Energy Solutions is MCS accredited for the installation of Solar Photovoltaic panels.
To qualify for the FIT your property must have an EPC rating of level D or better. Stratford Energy Solutions can arrange this for you.
Grid connected PV panels require very little maintenance.
You should ensure that any nearby trees are kept trimmed and the panels are relatively clean and we do recommend that the electrical installation part of the installation is checked regularly by a qualified electrician which can be part of a Stratford Energy Solutions maintenance package.
