The UK’s largest land owner, the Crown Estate, has given solar power its stamp of approval by installing a 164.5kWp rooftop system on a stone factory on the Isle of Portland in Dorset. Albion Stone, the owner of the factory, will save thousands of pounds on its annual electricity bill thanks to the system, which is expected to generate 150,000 kWh a year. Electricity generated from the £500,000 installation will be sold to Albion Stone at a reduced rate, with any surplus fed in to the National Grid.
