Energy efficiency & carbon emissions

We minimise our carbon footprint, keep our suppliers as local as possible, use recycled aluminium and minimise our packaging.  Our factory has a 30kW solar PV array on the roof, providing much of the power needed and also long-term testing of products in development.  GB-Sol has been rated the top solar supplier in the Ethical Consumer magazine for many years.
