SolaX Power — natural panel degradation

While degradation primarily affects panels, SolaX Power inverters also lose efficiency over time. With a typical lifespan of 10 years, efficiency loss becomes measurable after 5–7 years of continuous operation.

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.

Typical loss: 3–15%Detection: monitoringLikelihood: common

Self-check tip:

Compare current annual production to your system's first-year output. A decline beyond 1% per year may indicate accelerated degradation.
