Lightweight and compact, high performance collector panels are easily sited on pitched or flat roofs. Ideally they should be orientated south but they can operate with only a small loss of efficiency sited between 30 degrees east and 40 degrees … Continue reading →

The VAT on solar systems varies depending on who is installing it. DIY solar systems carry 15% VAT. A system installed by a professional installer carries 5% VAT.

The principles are quite straightforward. Solar collectors absorb energy from the sun to heat a fluid that is pumped in a sealed circuit to an indirect coil in a water cylinder to heat the domestic water.

Collectors are easily sited on pitched roofs, flat roofs, or in roof. Ideally the solar panels should be oriented to face south, but they will work with a small loss of efficiency sited between 30 degrees east and 40 degrees … Continue reading →

Vacuum tube collectors offer the highest operating efficiency all year round and, due to their low weight and smaller dimensions, offer easier installation and handling. Flat plate collectors should be used when efficiency during autumn, winter and spring is not … Continue reading →

As the panels work on diffused solar radiation as well as direct sunlight, they will even generate small amounts of energy on particularly cloudy days. This lowers the energy required from your boiler. The DTI has calculated that there are … Continue reading →

Solar heating systems will provide around 50-60% of annual domestic hot water requirements, but an auxiliary source is required for times of low solar energy to ensure there’s always hot water on demand. In addition, the boiler is also necessary … Continue reading →

There is not really a typical cost – it depends on the number of collectors required, the size of the cylinder and on installation details such as accessibility for the scaffold and the complexity of the wiring.
