How Long Do Solar Panels Last?: The Average Lifespan of Solar Panels
Curious about how long solar panels last? Most solar panels have a lifespan of 20 to 30 years, but they don't just stop working—they gradually lose efficiency over time. Factors like panel quality, proper installation, and environmental conditions can impact longevity. Panels typically degrade about 0.5% to 1% per year, so even after a decade, they still operate at 90-95% efficiency. Proper care, including regular cleaning, shade monitoring, and inspections, can help maximize their lifespan. Learn when to maintain, repair, or replace your panels to keep your solar investment running efficiently for decades!
