SolarSub provides a passive, zero‑energy‑input cooling system that attaches to photovoltaic modules to extract excess heat without moving parts. By keeping panels cooler, the technology can increase energy output by up to 20% and reduce degradation rates by about 57%, extending module lifespans beyond 40 years for utility‑scale and commercial solar projects.

Problem
Solar panels lose efficiency and degrade faster when operating at high temperatures, with overheating reducing output by up to 25% and accelerating wear, which lowers energy generation and project revenue.
Solution
SolarSub offers a passive, zero‑energy‑input cooling system that extracts excess heat from photovoltaic modules without moving parts. The technology is integrated onto the panel surface and relies on natural convection and heat‑transfer mechanisms to dissipate heat, eliminating the need for external power or active components. By maintaining lower operating temperatures, the system can boost panel output by up to 20% and cut degradation rates by roughly 57%, extending useful life beyond 40 years. The solution is compatible with a range of solar formats, including ground‑mounted PV, floating solar, PV‑thermal hybrids, and emerging perovskite cells, and is designed for straightforward retro‑fit or inclusion in new installations.
Target Audience
Primary customers are solar project developers, asset owners, and EPC firms seeking to improve the efficiency and longevity of utility‑scale and commercial solar installations.
