The photovoltaic–thermal (PVT) systems have been established for providing both electricity and heat using the existing photovoltaic (PV) system set-up. The PVT systems capture panel heat for some useful purpose. It is based on deploying a polymer sheet at the back of the PV panel to accommodate cooling water between the PV panel and the sheet to maximize the contact area between cooling water and panel. The present work compares the performance of a normal PV panel to that of the novel PVT panel. The PVT system is fabricated and experiments are conducted to evaluate electrical and thermal efficiencies. An improvement of 2.17% is observed in the electrical efficiency of the PVT panel in comparison with the normal PV panel. A brief cost analysis along with payback period calculations of the PVT panel is also included.

已经建立了光伏热能（PVT）系统，以使用现有的光伏（PV）系统设置来提供电能和热量。PVT系统会出于某些有用的目的捕获面板热量。它基于在PV面板的背面部署聚合物薄板，以在PV面板和薄板之间容纳冷却水，以使冷却水和面板之间的接触面积最大化。本工作将常规PV面板的性能与新型PVT面板的性能进行了比较。组装了PVT系统，并进行了实验以评估电效率和热效率。与普通PV面板相比，PVT面板的电效率提高了2.17％。还包括简短的成本分析以及PVT面板的投资回收期计算。
