Monocrystalline panels are built to last. Most manufacturers offer a 25 to 40-year performance warranty. This means they guarantee the panel will still produce a high percentage (often 80% to 85%) of its original power output after that many years.
Like their monocrystalline counterparts, polycrystalline panels also come with impressive 20 to 35-year performance warranties. Their expected functional life is also typically within that range, making them a very dependable choice for long-term energy generation.
Degradation Rate: Monocrystalline panels typically degrade at a rate of about 0.5% to 1% per year. This means that after 25 years, a panel might operate at 75-88% of its original capacity. Factors Influencing Degradation: UV exposure, temperature, and mechanical stress are primary factors that contribute to the degradation of solar panels.
