How much does it cost to have solar energy equipment installed?

Prices vary depending on the company you use. As a rough guide, Solar Twin provides hot water solar thermal panels, including fitting, from £3,300. Solaspin offers a typical solar system for a three or four bedroom house, including installation for £3995. Other systems can cost anywhere between £4,000 and £8,000.

Until 2008, grants of around £400 are available to have solar panels installed. See grant application details.

What will happen to my energy bills?

Your energy bills are likely to be lower if you have solar panels installed. This is because it is the sun which heats the water you use for baths, showers and heating, which means you do not need to heat water using an emersion heater. It is also worth remembering that energy prices are likely to rise considerably in the future – so now may be the time to invest in an alternative source.

In the summer, you could save around 70 per cent of the energy needed to heat your hot water. In winter months, the saving is likely to be approximately 50 per cent. On sunny days, water can be heated to a temperature of 70 to 85 degrees.

Is solar energy equipment reliant on the weather?

Solar equipment still works on cloudy days. The panels work during daylight hours, whether it is sunny or grey. In the United Kingdom, daylight hours are guaranteed, whereas an alternative energy source such as wind is not so reliable.

The panels are most efficient when they face south or south east, but they can be used facing any direction. Reputable companies will test their panels to ensure they are weather-resistant. Solaspin test their panels can withstand 125mph winds and one inch hail stones.
