REC Solar — natural panel degradation
All solar panels degrade over time, and REC Solar panels are no exception. With an expected lifespan of 28 years, you should expect roughly 0.5–0.8% efficiency loss per year under normal conditions. However, panels in hot climates or with manufacturing defects can degrade faster.
Natural panel degradation is a known issue for REC Solar panels. This doesn't mean it will affect your system — but it's worth monitoring.
Natural panel degradation details
All solar panels lose efficiency over time at roughly 0.5–0.8% per year. Accelerated in extreme heat or poorly manufactured panels.
Self-check tip:
Compare current annual production to your system's first-year output. A decline beyond 1% per year may indicate accelerated degradation.
