Solutions Solar PV Resource Monitoring

PV degradation & long-term performance

PV modules degrade, but the rate isn’t fixed. With precise irradiance, environmental, and performance data, developers and researchers can measure real‑world degradation, validate long‑term assumptions, and defend lifetime yield with confidence.

Quantify degradation to protect plant performance  

For utility‑scale developers, asset owners, EPCs, and research centers, understanding degradation is essential for accurate financial models and O&M planning. 

  • Track long‑term PV degradation with bankable accuracy

  • Measure irradiance, temperature, and environmental drivers of long‑term loss

  • Improve lifetime energy forecasts and P50/P90 modeling

  • Strengthen investment confidence with transparent, high‑quality data

Frequently Asked Questions
Why is accurate irradiance data essential for degradation analysis?

PV degradation must be normalized against true irradiance conditions. Without high‑quality GHI/DNI/DHI data, long‑term results can be misleading.

What factors commonly influence PV degradation rates?
How long should PV degradation be monitored?
Do Kipp & Zonen systems integrate with SCADA and third‑party analytics?
Are the sensors suitable for long-term remote deployment?
