PV Plant Performance Technical Briefing Published in PV Power Tech

The state of the art in PV system monitoring is relatively simplistic, relying either on comparisons of outputs between various parts of the system (e.g., inverters) or on an evaluation of a performance metric that normalizes output to available irradiance and other environmental conditions. However, neither of these methods is very effective in discovering the source [...]

Sandian Presents on PV Failure Analysis at European PV Solar Energy Conference and Exhibition (EU PVSC)

PV fault detection/monitoring system using machine-learning algorithms. A learning algorithm is trained to estimate power production based on meteorological data (irradiance, temperature, wind speed, etc.). This predic-tion is then compared to the actual power to detect various faults. Current research is focused on distinguishing different fault signatures. (Figure from Riley and Johnson, 2012) [...]
