Award Winning Solar Products

The hot water solar panels we supply were tested to be the one of the most efficient in Europe (ISFH 2001). In subsequent comparative testing in 2008 our solar pannels heating systems came top. Furthermore, there are 600,000 square metres of our German manufacturers' panels installed around the world, equating to a saving to date of 240 million litres of heating oil. Their headquarters (pictured below) is the first passively heated office block in Europe. It uses a large buffer tank (seen protruding from the roof) and a large panel surface. The resulting energy consumption is around 10% of that of standard offices.
