New solar addition may generate 21 kilotonnes of PV module waste by 2030
India’s solar capacity growth up to 2030 also means the generation of a significant mass of PV module waste due to early failures or damages during transportation, installation, and operation. The waste generation could be 21 kilotonnes assuming India’s cumulative installed PV capacity grows to 287.4 GW by 2030 from 40 GW in 2020. This doesn’t include end-of-life panel waste as PV systems installed between 2020-30 are assumed to have at least 30 years of lifetime.
