Our people

Originally established by six engineers from the Centre for Alternative Technology in Wales, Dulas has grown consistently over the years as demand for renewable energy technologies has increased.
As an employee-owned business and co-operative, the company has opted for organic, planned growth, rather than a rapid, step-change expansion.
Dulas now has over 50 employees in three locations: Machynlleth in Wales, and Stirling and Inverness in Scotland. Our solar refrigerator manufacturing facility, Polestar Cooling, is located in West Sussex. Our staff come from a wide range of backgrounds and cover a broad range of disciplines.
From specialist technicians and engineers to microgeneration installers and renewable energy service developers, Dulas has the expertise that you need to take your project to fruition.
