While the hardware is designed for longevity, its actual output will gradually decline due to environmental exposure and internal component degradation. Understanding how your system performance changes over this duration is essential for projecting your long-term financial returns:

• Years 1–10: Peak efficiency period where panels typically operate at or near their original rated capacity.
• Years 11–20: Gradual efficiency decline, usually occurring at a pace of 0.5% to 0.8% annually as silicon cells undergo natural wear.
• Years 21–30: Stabilization phase where the system persists to produce meaningful power, though output may remain at 80% to 85% of its initial nameplate rating.

Review the precise degradation rate documentation provided by the manufacturer in your offer to understand precisely how much energy output you can anticipate as your system approaches the end of its 30-year operational life.
