Government grants for solar homes are £400.00 against the cost of installation.
Solar hot water systems can produce 70% of required hot water per year and reduce fuel bills by up to 40% per annum. Solar heating panels have been installed in regions as extreme as the Arctic and Antarctic and have still proved to provide hot water. Heating is dependent on sunlight rather than the ambient temperature, so even on the coldest days experienced in the UK, as long as there is sufficient sunlight falling on the tubes, heating will be effective.
However, it can take several years at today's prices to pay off your investment. Having said that, energy prices are set to increase by 40% by the end of 2008, so your investment is now likely to be paid off earlier. Your investment in reducing your carbon footprint will start immediately.
The advantages of vacuum technology
. High water temperatures and high efficiency even in unfavorable atmospheric
conditions, such as an overcast sky, or in case of low temperatures.
. High solar absorption even from oblique light, thanks to the circular
shape of the absorber
. Excellent heat exchange capacity.
. Long life, as there are no metallic passages interrupting the glass pipe
and compromising the vacuum
. Long life, as the selective surface is protected by the vacuum.
. Very high year-round output
. Attractive shape and design
Costs of installing solar panels.
Be prepared to spend in the region of £4,000 - £6,000 for solar water heating panels for the average house and to receive £400 back in the form of a government grant.
