Arley Homes is to install solar panels at its new development in Coppull, Chorley, which it says will produce 55% of the household's annual hot water requirements.
The thermal solar panel system heats water which is then stored until the hot tap is switched on. Homes will also be fitted with a traditional boiler to top-up the system when needed.
The blue-green panels will lie flush to the roof and blend into the gray slate tile to ensure the homes meet the Arley Homes standard for aesthetic quality and design.
John Cosgrave, managing director of Arley Homes, said: "Modern homes are a far cry from the drafty, energy-sapping buildings of yesteryear. All responsible housebuilders incorporate the latest standards in insulation and water conservation measures into their designs to make properties as energy efficient as possible.
"Reducing energy consumption has become a pre-requisite and has the twin benefits of not only helping to protect the environment but also has a very positive impact on the homeowner's pocket with new build homes offering a typical cost saving of up to £560 a year.
"However, very few housebuilders are investing in renewable energy on a large scale as Arley is doing here on our Coppull development. These panels will provide up to 55% of the homes' annual hot water needs which I believe will prove popular with buyers."
The Warrington-based housebuilder secured planning permission for the 2.7 acre development in November and started construction earlier this year. Arley intends to launch the show home and commence sales in the spring.
There will be 29 three- and four- bedroom detached homes in a range of house types.
