摘要：

Recent studies of solar radiation have shown that instantaneous solar radiation exhibits a distinct bimodal character associated with clear and cloudy states. This suggests that many solar systems may simply be modelled to operate in an on/off fashion corresponding to clear/cloudy time intervals. It is shown that the average-daily solar system performance may be calculated from the product of clear-sky solar performance and the average time fraction of clear sky. This approximation greatly simplifies the solar system performance prediction. The proposed method is verified with a solar hot water system. The predicted results compare favourably with results predicted by the phi-fBAR chart method and give a conservative estimate of the experimentally measured performance.
