Technical failures - field data

In Solar Bankability, the role of the FMEA was to focus on the most important failure risks with respect to their impact on electrical and financial performance. An example of FMEA rating of PV module failures is given in the diagram below.

Failures on cabling/connectors are among highest risk potentials according to the list of The TOP 20 Technical Failures during Operation and have the biggest financial impact.
