The big question isn't just about photovoltaic panel installation reliability, but whether your investment will keep humming like a contented cat for decades. Recent data from the National Renewable Energy Laboratory (NREL) shows modern PV systems now achieve 99.5% first-year reliability rates. But here's the kicker: does this reliability hold up in real-world condition
