Environmental sustainability in PV technology advancements – life cycle assessment of PERC modules

As photovoltaic (PV) technologies evolve, understanding their environmental implications is crucial for a sustainable energy transition. IEA PVPS Task 12 analyzes the environmental impact of passivated emitter and rear cell (PERC) technology in PV installations in comparison to the monocrystalline silicon technology (AI-BSF) and the trend towards installing horizontal singla-axis tracker systems as opposed to fixed tilt systems. Primary data from one PERC and tracker manufacturer enable this study’s conclusions. Using the life cycle assessment (LCA) methodology, the study compares two locations in Italy with different irradiation patterns to evaluate the sensitivity to solar irradiation. The findings reveal that PERC technology and horizontal single-axis tracker systems demonstrate lower environmental impacts compared to Al-BSF and fixed tilt configurations.
