Sunnier outlook for solar! ☀️ Real-world data from 1.25 million systems over 16 years reveals PV degradation is just 0.52-0.61% annually—half of prior estimates! This boosts long-term reliability and profitability, making solar an even smarter, more sustainable investment. #SolarPower #RenewableEnergy
Solar PV annual degradation is just 0.52–0.61%, half of prior estimates, as shown by 16 years of real-world data from 1.25 million power systems. Heat, frost, maintenance, and air pollution affect performance, with smaller systems degrading less, boosting long-term reliability and profitability.
