Solar energy is greatly recommended as a source of renewable energy in wide range of in-house applications to large power plants. Photovoltaic (PV) panels utilized for absorbing solar energy have some limitations: low efficiency, large occupied space and high dependency on environmental conditions. Panel surface temperature is one of the main conditions affecting PV panels. High temperatures would lead to lower panel efficiency. Therefore, researchers have proposed hybrid PV/thermal systems where maintaining panel temperature for higher efficiency is participated in heat production. This benefit made it attractive for household consumption. In this paper, a numerical method is deployed to find an appropriate cooling tube configuration for a specified panel. The selected configuration was prepared for experimental studies on a hybrid PV/thermal system in the northern part of Iran. As this region receives lower irradiation compared to southern parts, People are not persuaded to use photovoltaic systems, so using hybrid systems can motivate them to use solar energy on a small scale. Results showed that serpentine tube configuration would lead to a 7.3% increase in electrical efficiency compared to the no-cooling state, and also thermal efficiency raised to 48.4%. Total efficiency reached 51.76% at the highest performance. Therefore this design provides a possible platform for increasing PV/T systems performance.

在大型发电厂的各种内部应用中，强烈建议将太阳能用作可再生能源。用于吸收太阳能的光伏（PV）面板具有一些局限性：效率低，占用空间大以及对环境条件的依赖性高。面板表面温度是影响光伏面板的主要条件之一。高温会导致面板效率降低。因此，研究人员提出了混合光伏/热力系统，其中维持面板温度以提高效率参与了热产生。这种好处使其对家庭消费具有吸引力。在本文中，采用了一种数值方法来为指定的面板找到合适的冷却管配置。选择的配置是为在伊朗北部进行的混合光伏/热力系统的实验研究而准备的。由于与南部地区相比，该地区受到的辐射较低，因此人们不被劝说使用光伏系统，因此使用混合系统可以激发人们小规模使用太阳能。结果表明，与非冷却状态相比，蛇形管结构将导致电效率提高7.3％，热效率也提高到48.4％。在最高性能下，总效率达到51.76％。因此，该设计为提高PV / T系统性能提供了可能的平台。因此使用混合动力系统可以激励他们小规模使用太阳能。结果表明，与非冷却状态相比，蛇形管结构将导致电效率提高7.3％，热效率也提高到48.4％。在最高性能下，总效率达到51.76％。因此，该设计为提高PV / T系统性能提供了可能的平台。因此使用混合动力系统可以激励他们小规模使用太阳能。结果表明，与非冷却状态相比，蛇形管结构将导致电效率提高7.3％，热效率也提高到48.4％。在最高性能下，总效率达到51.76％。因此，该设计为提高PV / T系统性能提供了可能的平台。
