About 25-year attenuation value of photovoltaic panels
Global installed PV capacity reached around 400 GW at the end of 2017 and is expected to rise further to 4500 GW by 2050. Considering an average panel lifetime of 25 years, the worldwide solar PV waste is anticipated to reach between 4%-14% of total generation capacity by 2030 and rise to over 80% (around 78 million tonnes) by 2050.

Globally, PV waste is projected to make up 4 %–14 % of total generation capacity by 2030 and more than 80 % by 2050 due to a 25-year average panel lifespan. Therefore, PV panel disposal will be a significant environmental concern.
Given the average life of solar modules is 25 years, after their spent time the installed solar panels will eventually turn into waste. The waste from solar panel modules is expected to reach about 8600 tons by 2030 and it will further increase to 78 million tons by 2050.
This study: UV-LID verified, separate from B-O LID (stabilized beforehand) and LETID (low temperature test used). Common ∆Pmax is -0.6 %⋅y-1 (bare cells, chamber:field UV dose) → -0.1 %⋅y-1 (AM1.5, PV module), with the maximum degradation rate up to -4 %⋅y-1 → -0.7 %⋅y-1 (at 340 nm).
The lifetime of photovoltaic modules is most commonly considered to be 25 years based on performance guarantees of 80% power output after 25 years of operation; however, influences including climatic conditions, social behaviour, fiscal policy, and technological improvements have the potential to prompt early replacement.

6 FAQs about [25-year attenuation value of photovoltaic panels]
How long do photovoltaic modules last?
The lifetime of photovoltaic modules is most commonly considered to be 25 years based on performance guarantees of 80% power output after 25 years of operation; however, influences including climatic conditions, social behaviour, fiscal policy, and technological improvements have the potential to prompt early replacement.
How to reduce the cost of a new PV power plant?
Extending contracts, renovating, and repowering demand additional investments, which may reduce the cost of the new PV power plant of the same capacity. After decommissioning, PV panel recycling should be the first focus. 100 discarded/damaged solar panels could yield 42 new photovoltaic panels .
How long will PV panels last?
In estimating the volume of future PV waste, IRENA and IEA-PVPS projected a regular loss scenario based on an average panel lifetime of 28 years, and an early loss scenario that considers ‘infant’, ‘mid-life’, and ‘wear-out’ failures shortening the average lifetime to 26 years.
Will PV panel disposal be a significant environmental concern?
Globally, PV waste is projected to make up 4 %–14 % of total generation capacity by 2030 and more than 80 % by 2050 due to a 25-year average panel lifespan. Therefore, PV panel disposal will be a significant environmental concern.
Will solar PV waste be recycled by 2040?
Based on the swift growth in the installed PV generation capacity, we propose that the number of EOL panels will necessitate a strategy for recycling and recovery which need to be established by 2040. CO 2 emissions could also be reduced by recycling solar PV waste which will consequently pose substantial positive impact on the environment.
Does light induced degradation affect photovoltaic conversion efficiency?
Passivated emitter and rear cell (PERC) photovoltaic (PV) modules' conversion efficiency is also affected by light-induced degradation . LID has been observed in four main categories. They have traditionally included Iron Boron (FeB) and Boron Oxygen (B-O) LIDs; newly reported LIDs are sponge-LID, bright, and elevated temperature LID (LeTID).
