Implementation and demonstration of cost-effective wireless monitoring module for PV system

Photovoltaic (PV) is an attractive renewable energy source and the global cumulative PV capacity is growing steadily. Implementation of a cost-effective wireless PV monitoring system at panel level is required in order to apply it commercially to the massive number of PV panels and to enhance convenience of maintenance of PV systems. This paper proposes an implementation method for cost-effective wireless PV monitoring module (WPMM), and describes demonstration results on the practical PV system.
