In present communication, greenhouse solar dryer under forced mode integrated with different types of photovoltaic (PV) technologies have been proposed. Further, various parameters have been evaluated on environmental point of view for different weather condition of New Delhi, India. For numerical analysis, radiation data and ambient air temperature have been taken from IMD (Indian Meteorological Department), Pune. Further, different parameter such as crop temperature, greenhouse temperature and cell temperature have been calculated with experimental validation by the help of MATLAB 2013a. Overall (equivalent) thermal energy found to be 1838.16, 1740.98, 1351.22, 1472.12 and 1527.86 kWh for c-Si, p-Si, a-Si, CdTe and CIGS PV technologies integrated with drying system respectively on yearly basis. Further, embodied energy, energy payback time, CO2 mitigation and carbon credit earn through different PV drying system have also been calculated. It was found that payback time for c-Si, p-Si, a-Si, CdTe and CIGS system are 1.13, 0.98, 0.93, 0.82, and 0.39 years respectively on the basis of equivalent thermal energy. © 2017 Elsevier Ltd
