在本研究论文中，混合光热（PVT）单坡屋顶集成温室太阳能干燥器在自然和强制模式下进行了测试，印度新德里的气候条件。对PVT干燥器的热模型进行了自然和强制无负荷工况下的实验验证。此外，还讨论了基于热效率、总热效率、总火用效率和太阳能电池效率的特性曲线，包括填充因子和质量流量的影响。随着组件封装系数的增加，组件的热能降低了76.39%，电能增加了88.73%。随着质量流量的增加，自然模式和强迫模式下的热能分别增加了89.44%和65.70%。
In this research paper, a hybrid photovoltaic-thermal (PVT) single slope roof integrated greenhouse solar dryer under natural and forced mode has been tested for climatic condition of New Delhi, India. Thermal modelling of PVT dryer has been experimentally validated under natural and forced mode without load condition. Further, characteristic curves have also been discussed on the basis of thermal efficiency, overall thermal efficiency, overall exergy efficiency and solar cell efficiency including the effect of packing factor and mass flow rate. The thermal energy decreased and the electrical energy increased by 76.39% and 88.73% respectively with increment in packing factor of PV module. It was also found that with increment in mass flow rate, the thermal energy increased by 89.44% and 65.70% for natural and forced mode respectively.
