Traditional solar photovoltaic (PV) systems convert approximately 15-17 percent of the sun’s energy into usable electricity, discarding the remaining energy as waste, mostly in the form of heat. Solar cogeneration captures this waste heat and transforms it into real value — hot water. This cogenerative solution not only generates further savings, it also cools the PV components, enhancing their efficiency and boosting the system’s electricity generation and lifetime.

This technology captures up to 75 percent of the sun’s delivered energy and converts it into both electricity and hot water within a single solar array. This approach yields five times the energy of traditional PV systems. To achieve these dramatic efficiency gains, Cogenra integrates advanced silicon PV cells, concentrating optics with single-axis tracking and an innovative thermal transfer system in a low-cost and scalable design.
