SolarSub has raised $1.7M in pre-seed funding to push forward a cooling system it says can boost solar panel efficiency by up to 20%. The invention is built for floating solar panels mounted on bodies of water, a setup the company argues is more sustainable than land-based arrays.
The round drew backing from Sustainable Ventures, Zinc, Scottish Enterprise, Old College Capital, SFC Capital, British Business Bank, and Innovate UK. SolarSub says its design also tracks the sun, adding another 30% in efficiency gains.
