DC inspection: Its quality check service for PV systems offers energy provider Eon insights into the quality of PV plants, even systems that appear to be trouble-free. PV system owners including those that are unaware of any defects or reduced yield have gladly take advantage of the service. Testing institutions like TUV, or insurance companies generally take a dim view of the quality of PV systems and see plenty of room for improvement. But such organizations are usually only called in once someone has noticed a drop in yield or some other deficiency. The sample of systems they see can bias the fault statistics of the testing organizations and is no way to obtain a general picture of the condition of a cross-section of all the PV systems in installed in Germany.
