Present communication is an attempt to explore the best PV technology suitable for PVT solar drying system through environmental and economic feasibility. Experimental setup for one of the PV technology (c‐Si) has been taken for experimental validation with theoretical model. Further, the environmental feasibility and environ economic evaluation for drying system having roof with various PV namely, c‐Si, p‐Si or m‐Si, a‐Si, CdTe, and CIGS have been evaluated through energy matrices (EPBT, EPF, and LCCE), CO₂ emission, net CO₂ mitigation and carbon credit earned which is based on energy and exergy output of the system on yearly basis. The economic analysis has been carried out with experimental data taken on c‐Si PVT drying system by considering grapes as a crop. Cogeneration efficiency has been calculated for different PV technologies and found to be highest for c‐Si PV technology that is, 61.71%, 77.98%, and 12.25% based on energy (electrical and thermal) gain, equivalent (overall) energy gain, and exergy gain, respectively. LCCE on energy basis reveals that for the five‐year system life, c‐Si and CIGS have equal efficiency but after five years, c‐Si is best. Cogeneration efficiency of system on the basis of energy (electrical + thermal) gain, equivalent (overall) energy gain and overall exergy gain found to be maximum with c‐Si PV technology that is, 61.71%, 77.98%, and 12.25%, respectively.

PVT干燥系统的环境和经济可持续性：一种传热方法

当前的交流是试图通过环境和经济可行性来探索适用于PVT太阳能干燥系统的最佳PV技术。已采用一种光伏技术（c-Si）的实验装置进行了理论模型的实验验证。此外，已通过能源矩阵（EPBT，EPF，和LCCE），CO ₂排放，净CO ₂减排和碳信用额度，该额度是基于系统每年的能源和火用输出量得出的。通过将c-Si PVT干燥系统中的实验数据作为葡萄进行经济分析。根据不同的光伏技术计算出的热电联产效率，发现c-Si光伏技术的最高热效率分别为61.71％，77.98％和12.25％（基于能量（电和热）增益，等效（整体）能量增益和火用增益分别。LCCE的能耗显示，在系统的五年使用寿命中，c-Si和CIGS的效率相同，但五年后，c-Si的效果最佳。基于能量（电+热）增益，等效（总体）能量增益和总火用增益的系统热电联产效率在c-Si PV技术中达到最高，分别为61.71％，77.98％，
