In an earlier work, a temperature-dependent photovoltaic efficiency difference factor, F_TDED, was introduced for the purpose of evaluating the performance of the photovoltaic module (PV) cooling technique. The evaluation is achieved by indicating if the PV cooler performance is contributing to the photovoltaic efficiency gain or loss. The existing method (F_TDED) is costly because of the use of a fixed solar radiation of 1000 W/m², that is the solar radiation at PV's standard test conditions, and the involvement of one unit of a PV without a cooling technique that has the same number of solar cells as a PV with a cooler which are required to accomplish the performance evaluation. To solve the performance evaluation cost issue, a new method is proposed. This method can execute the performance evaluation of the PV coolers as the existing method but under various solar radiation values. It also depends on the output power of a PV with a single solar cell only (without a cooler) when conducting the performance evaluation for a PV with a cooler that has a known number of solar cells. The applicability conditions of the proposed method are illustrated. It is shown that the performance evaluation cost of PV cooling techniques can be greatly reduced. It can be concluded that the new method is a cost-efficient as compared with the existing method. PV cooling techniques designers and manufacturers are the potential users of the proposed method.

在较早的工作中，引入了随温度变化的光伏效率差异因子F _TDED，以评估光伏模块（PV）冷却技术的性能。通过指示PV冷却器的性能是否有助于光伏效率的增加或减少来实现评估。由于使用固定的1000 W / m ²太阳辐射，因此现有方法（F _TDED）成本_很高。，即在PV的标准测试条件下的太阳辐射，以及不带冷却技术的一台PV的参与，该技术具有与完成冷却性能评估所需的带有冷却器的PV数量相同的太阳能电池。为了解决绩效评估成本问题，提出了一种新的方法。该方法可以像现有方法一样在各种太阳辐射值下执行PV冷却器的性能评估。在对具有已知数量太阳能电池的冷却器进行PV的性能评估时，它也仅取决于单个太阳能电池（不具有冷却器）的PV的输出功率。说明了该方法的适用条件。结果表明，可以大大降低PV冷却技术的性能评估成本。可以得出结论，与现有方法相比，该新方法具有成本效益。光伏冷却技术的设计者和制造商是该方法的潜在用户。
