What are solar panels?
These are specially devised panels that collect and convert solar (sun) energy into electricity or heat (water). It is important to remember that the light is a critical factor in solar systems, not the heat.
What types are available?
There are 2 main types of solar panels which uses complete different technologies to make use of the energy from the sun: · Solar Water heating collectors: These panels absorb the energy from the sun and transfer it to heat water. Provides 60 to 70 % of a household’s yearly hot water needs. · Photovoltaic or solar electric panels: These panels transform the solar radiation directly into electricity. Provides around 6 to 15 % of a household’s yearly electricity. For maximum efficiency, solar panels should be mounted on a south facing roof at a 30° angle with the horizontal and away from any shadows from trees, surrounding buildings or chimneys.
Benefits
In the event of a power failure households with their own energy supplies could be largely unaffected. On average it can save 2.8 tonnes of CO² per year and around 56 tonnes over its lifetime. By fitting solar power as well reducing your fuel bills you will be increasing the value of your home if you decide to move in the future.
Installation
It usually takes 1 day to install the panels. If a boiler needs to be installed as well then it can take up to 2 days to install the complete system.
Costs
The costs for a solar system and the installation depends on 2 factors; the amount of panels and if a new boiler needs to be installed. The total costs vary between £2,500 (DIY kit) to £5,000.
Planning Permission
Generally, you can install solar panels on a wall or a roof without the need for planning permission provided that you adhere to certain rules. One being that no part of the panel(s) exceeds the highest part of the roof of the original house. However, it is important to inform your local council of your plans.
Grants
When installing a solar thermal hot water system, you can apply for a grant of maximum £400 or 30% of the total installed costs. If you decide to install a solar photovoltaic system instead, there is a grant of maximum £2,000 per KW installed (subject to an overall maximum of £2,500) or once again a percentage of the total installed costs, which is 50%. The amount that the grants cover are for costs made before the VAT is added. After your request is granted the installation has to be completed within 3 months for thermal systems and 4 months for photovoltaic systems. Local authorities, housing associations, charities and non profit-organisations can apply for grants of 50% of solar water heating project costs under the Clear Skies programme.
