How Long Do Solar Panels Last Without Maintenance?
Solar panels can technically last 25-30 years, but without proper solar panel maintenance services and solar AMC services in India, their performance can drop much faster than expected. Even basic upkeep like a solar panel cleaning service or rooftop solar maintenance can make a big difference in how long your system performs efficiently. Let’s break this down in a simple, practical way so you understand what really happens when solar panels are left without maintenance. Understanding Solar Panel Lifespan Most people think solar panels “stop working” after a certain number of years. That’s not true. Instead, solar panels: Continue producing electricity for decades Slowly lose efficiency over time Require occasional maintenance to perform at their best Average Lifespan Factor Expected Value Total lifespan 25–30 years Peak efficiency period First 10–15 years Degradation rate ~0.5% to 1% per year Performance after 25 years ~75–85% Even without maintenance, panels don’t suddenly fail-but their output drops faster, which means less savings on electricity.
