Two-sided solar panels that track the sun produce a third more energy
Double-sided solar panels that tilt based on the sun’s position could boost the amount of energy collected. The two approaches existed independently before, but researchers have now looked at the effects of combining them.
Carlos Rodríguez-Gallegos at the Solar Energy Research Institute of Singapore and his colleagues found that double-sided solar panels that track the sun would produce 35 per cent more energy and reduce the average cost of electricity by 16 per cent.
