One type of solar technology, concentrated photovoltaic (CPV), is able to convert the sun’s energy to electricity more efficiently. This approach magnifies the sun’s rays and concentrates them on high-quality photovoltaic (PV) cells. Unfortunately, concentrating the sun’s light on a small area generates a large amount of heat on the PV cells, which can cause damage. Fortunately, the heat can be removed and used for other purposes.

This innovation is a passive cooling system for CPV solar, but it can also be used with conventional photovoltaic solar systems. A passive system requires no electricity to power fans or pumps to cool the solar system. At the same time, the waste heat is an asset that can be used for other applications. Ideal settings for this technology include small- to medium-sized solar farms, urban and city solar projects, and co-generation energy systems.
