In total, more than 3,500 homes in the town will get PV panels. Mears will install ‘a significant proportion’, and will also carry out all associated works such as scaffolding and electrical components.
It is believed to be the largest social housing PV scheme in the UK, Mears said.
The contract is for Cross Keys Homes but is being funded by British Gas as a part of a 25-year feed-in tariff scheme.
The first PV panels in the scheme will be fitted in September 2011, with all works completed by April 2012.
Mears chief executive David Miles said: "We see increasing opportunities in this area into 2012, particularly as the 'Green deal' and other energy efficiency measures come into play. Cross Keys will provide us an important reference site to lead our drive into this emerging energy opportunity as we continue to successfully leverage our partnership with British Gas, which gives us access to both funding and expertise in this area."
