مطالعه انرژی بازپرداخت زمان ساخت مجتمع فتوولتائیک

Building Integrated Photovoltaic system (BIPVs) is a measure of utilizing renewable energy, and has received great attention from researchers and powerful financial support by government.This paper use life cycle assessment to calculate the energy payback time of three different photovoltaic System, namely single-crystalline silicon, multi-crystalline silicon and amorphous silicon. Energy payback time of three systems is 3.0-7.4 years, which is far less than the PV system’s life cycle, hence theoretically three photovoltaic systems are all sustainable and environmentally friendly renewable energy systems from the perspective of energy consumption.
