Air pollution cut solar electricity generation by 5.8% in 2023, with coal-related aerosols responsible for huge losses in solar power output.

Technicians dismantled the vintage 10-square-meter 1-kilowatt solar array last year, running the solar panels through rigorous lab testing per international standards and finding impressive results.

Why it matters: Solar panels are meant to last for decades, with an estimated operational lifespan of 20 to 40 years. However, their efficiency and the ability to generate power will degrade over time ...
