The £20m contract award from Cross Keys Homes in Peterborough has been won with Mears’ partner British Gas and will see solar panels fitted to more than 3,500 homes.
The installation costs are being funded by British Gas as a part of a Feeding in Tariff scheme over a 25 year period.
Mears will carry out installations as well as all associated works such as scaffolding and electrical components.
The contract starts in September and will be completed by next April.
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.”
