摘要

工作温度高会降低光伏组件的效率。据报道,硅晶体的正常工作电池温度约为49°C。设计、制作并在光伏背面安装了一套逆流水循环冷却装置,部分避免了光伏背面温度升高带来的不良影响。这个带有冷却装置的改进模块和类似的非冷却模块安装在Dehradun石油和能源研究大学的户外,相同。安装正常工作单元温度,两个模块的INOCT由不同的冷却水流量来确定和比较。此外,水流速度优化,以保持最低可能的工作温度。

Operating temperature of PV module modified with surface cooling unit in real time condition
High operating temperature decreases photo voltaic module efficiency. Normal Operating Cell Temperature, NOCT of silicon crystalline is about 49°C as reported. A cooling unit with reverse flow water circulation is designed, fabricated and applied on PV back surface to partially avoid undesirable effect of its temperature increase. This modified module with cooling unit and similar non-cooled modules are installed outdoor identically at University of Petroleum and Energy Studies campus, Dehradun. Installed Normal Operating Cell Temperature, INOCT of both the modules are determined and compared by varying water flow rate from cooling unit. And also water flow rate is optimized to maintain minimum possible operating temperature.
