SolarSub builds passive, no-moving-parts cooling systems that keep photovoltaic panels cooler so solar operators can generate more electricity and extend panel life.
SolarSub targets the heat problem in photovoltaics: hot panels generate less electricity and degrade faster, while its passive system has no pumps or moving parts and has recorded energy gains of up to 17.5% at the University of Edinburgh's FloWave facility and up to 19% in Dubai testing. The £1.34 million round is intended to fund further product development, independent testing, international real-world deployments, and preparation for manufacture and certification as the company targets floating solar before wider utility-scale solar.
