Reliability assessment of photovoltaic power systems: Review of …
The total capacity of grid-connected PV power systems has been grown exponentially from 300 MW in 2000 to about 67 GW in 2011 [1]. This capacity, however, is not firm because of the unreliable nature and probabilistic behavior of PV power systems. Relatively high risks exist both inside and outside of PV power systems [2].

Failure Causes in Solar PV Systems
During the first 10 years in service, the chance of failure within a PV system is approximately 10%. Inverters and other electronic devices account for 85% of all those PV system failures. Only about 1 in 2000 modules will fail during their warranted 25-year life. The system components most likely to fail are the ones with complex electronic circuitry.
