Abstract

Building integrated photovoltaics modules (BIPV) heat up more than rack mounted ground arrays, and thus have power performance losses due to elevated temperatures. Airflow is restricted in BIPV or low profile, aesthetically pleasing, building applied photovoltaic (PV) arrays. The electrical production losses are significant. This paper investigates the electrical loses, and proposes forced air, using waste cooling from the first stage of two stage evaporative coolers as a source of increased electrical production for BIPV. Modern two stage evaporative coolers have less water consumption than markets perceive. Water usage for a PV powered two-stage evaporative cooler is compared to central station electrical plant powering direct expansion air conditioning for the western region of the United States. By comparison, the evaporative cooler is shown to be very conservative in water consumption. As PV module efficiencies approach 20 percent, forced aircooling becomes more attractive for peak power production. Photovoltaic / Thermal (PV/T) collectors harvest waste heat from the backs of PV arrays during the winter when lowgrade heat is desirable. The same mechanical system used to harvest heat from a PV/T in the winter can be used to cool the modules in the summer.
