Lightsource Renewable Energy and Octopus Investments have completed the installation of a 1.35MW solar project on the roof-top of Promens warehouse in Beccles, Suffolk, UK.

The roof-top installation was developed by Lightsource, built by Grupotec and funded by Octopus.

The company said this is the largest roof-top project in the UK and consists of 7,000 solar panels.

The installation has been completed ahead of the 1 August 2011 deadline, making it eligible to receive the government’s current feed-in tariff for larger sites of 50KW or more capacity.
