Many photovoltaic module cooling techniques are available to reduce the solar cell temperature, resulting in enhanced efficiency. Although the power of the photovoltaic module is usually reported as a measure for the performance of the cooling technique, the performance assessment and comparison among different coolers become difficult if different photovoltaic module’s reference power is being utilized. The existing method requires calculations to be done repeatedly to obtain the photovoltaic module’s power, for any given value of the reference power. In order to compare the performance of the coolers, the use of the same reference power is needed, resulting in a lengthy process. Hence, a new assessment method is proposed, based on the temperature dependent photovoltaic module’s power ratio that is defined and derived. The new method identifies the relevant parameters that are essential for measuring the performance of the cooler such as the power of a photovoltaic module with a cooler and the reference power at photovoltaic module’s standard test conditions. The outcome is that the calculation of the unknown power for different reference power can be instantly obtained and the performance comparison among different coolers become simple without going through the lengthy process as it is in the case of the existing method. It is shown that the proposed method has the same results as the existing method which is experimentally validated. This is evidence to support the new method which may have potential to be applied by photovoltaic module cooling techniques designers.

许多光伏模块冷却技术可用于降低太阳能电池温度，从而提高效率。尽管通常将光伏模块的功率报告为冷却技术性能的量度，但是如果使用不同的光伏模块的参考功率，则在不同冷却器之间的性能评估和比较将变得困难。对于任何给定的参考功率值，现有方法都需要重复进行计算以获得光伏模块的功率。为了比较冷却器的性能，需要使用相同的参考功率，从而导致过程冗长。因此，基于已定义和推导的与温度相关的光伏模块的功率比，提出了一种新的评估方法。新方法识别了测量冷却器性能必不可少的相关参数，例如带有冷却器的光伏模块的功率以及光伏模块标准测试条件下的参考功率。结果是，可以立即获得针对不同参考功率的未知功率的计算，并且无需像现有方法那样经过冗长的过程即可简化不同冷却器之间的性能比较。结果表明，所提方法与已有方法进行了实验验证，结果相同。这是支持新方法的证据，该新方法可能具有光伏模块冷却技术设计人员可能应用的潜力。
