How long do solar panels last?

While manufacturers typically guarantee performance for 25 years, a well-maintained solar panel can continue to produce reliable energy for 30, 40, or even 50 years. Understanding their average lifespan and the factors that affect performance is critical for maximizing your return on investment and ensuring a truly sustainable energy future.

Why do solar panels need a battery system?

While panels continue to produce some energy on cloudy days, a battery system ensures a stable and consistent power supply, especially during periods of high fluctuation. It allows you to store excess energy generated on sunny days and use it when the weather is not cooperating. Myth: Rain and clouds permanently damage panels.

Why do solar panels have a long-term warranty?

This built-in durability is a key reason why manufacturers offer long-term performance warranties. According to NREL performance modeling, panels in regions with frequent cloud cover still achieve viable energy yields over a year. Annual production models account for seasonal cloud patterns.
