Dunster's practice - which has recently become known as Zed Factory - will sell photovoltaic panels and solar-thermal hot-water panels through a new online shop called Zed Fabric, which will be hosted on the www.zedfactory.com website.
And now he looks set to profit from this exercise with the launch of the shop. Commenting on the move, Zed Fabric's new director Wendy Lee was determined to push the commercial element of the new venture.
'Our offer on solar thermal water panels is an even better example of how well we compete with the Low Carbon Building Programme.
'We offer 2 x 16 evacuated tubes, solar-thermal panels at £490 & VAT - a total of £580 excluding installation. Similar products that are accredited for grants start at around £1,120 & VAT excluding installation.
'With the maximum Low Carbon Building Programme grant of 30 per cent, you can claim back £400, which means a bill of around £980 compared with £580 if you buy from us.'
Zed Fabric will be up and running in February.
