New research suggests optimal tilt angle, overhead height for rooftop PV systems

Researchers in China have investigated the effect of the overhead height and tilt angle on thermal and energy-saving performance of photovoltaic roof and have found that the comprehensive energy-saving efficiency of parallel overhead photovoltaic roofs are optimal in summer and the worst in winter.Researchers from China's Guilin University of Electronic Technology have proposed a new model to investigate the impact of different overhead heights …
