摘要

To optimize PV system operation under extreme conditions, it is necessary to understand the behavior of the PV module as a function of temperature. This is particularly important when considering PV modules for large-scale economical power generation in very hot climates. A decrease in P_(max) with solar cell temperature is the principal tendency. On two days (30.08.2000 and 26.09.2000) with almost equal solar energy values (≈ 8400 W.h.m~(-2)) but different average cell temperatures (54 and 45?, respectively), average amounts of electricity of 144 and 158 W.h were generated by the module studied; ie. there was a ~10% reduction in the generated electricity for a 10℃ increase in average cell temperature. This effect should be kept in mind when PV systems are designed for use in hot climates.
