On the basis of the measured incident angle modified coefficient of the collector panels, the relation between the daily and instantaneous efficiency is given. 在測試了該集熱器陣列的入射角修正係數的基礎上給出了全日效率與瞬時效率的關係。
Also the influence of solar field size to the system performance was studied, and the result reveals that the optimal field size shifts to a higher value with decreasing DNI. 同時提出了最佳集熱器陣列面積的概念，模擬計算表明，該最佳面積隨著直射太陽輻射通量的降低逐漸增大。
