High quality solar panels can be expected to last for 25 years or more, but other PV system components have shorter service lives. Solar inverters have a typical service life of 10 years. This means your solar panels will still have 15 years of guaranteed power output when your first inverter reaches the end of its service life.
After 25 years, most panels still produce over 80% of their original power. Don't give up on those aging solar panels. They'll keep working longer than you think. Many people believe solar panels stop working after 20 years, but that's untrue. These super-durable energy savers keep producing electricity decades after installation.
Modern solar panels achieve efficiencies of 18-22% for residential applications, meaning they convert roughly one-fifth of the sunlight that hits them into electricity. Premium panels from manufacturers like Panasonic can achieve even higher efficiencies, reaching 22-24%. A complete rooftop solar system consists of several essential components:
Solar inverters have a typical service life of 10 years. This means your solar panels will still have 15 years of guaranteed power output when your first inverter reaches the end of its service life. If you're considering a solar power system with energy storage, home batteries also have a typical service life of 10 years.
