'PVRessQ!':PV, Reliable, Safe and Sustainable Quality! - Introduction of Field Survey Activities of Actual Operational Performance on Residential PV systems

摘要

This paper introduces the outline of 'PV RessQ!' (PV, Reliable, Safe and Sustainable Quality!) activity, on which the author just started the last year. The objective of this activity is to establish practical maintenance techniques and their social system given from results of many detailed field surveys on actual operational performance of residential PV systems. Also case studies of two field surveys are briefly discussed: one is a PV system failure due to DC cable disconnection, and the other is hidden malfunction of a PV module.
