Abstract
An array of PV panels connected in series or parallel typically makes up a solar PV system. When a single photovoltaic panel fails, the electrical network breaks, lowering the net power production concurrently. As of now, no significant, cost effective approach is suggested for identification and isolation of faulty panel.This works aims to experimentally verify automatic identification of break/fault in an electrical network of solar PV system by means of the Internet of Things (IoT). Furthermore, preventive maintenance attribute based on dust level over the exposed area of PV panel is suggested as a means to ensure reliable functioning of the solar PV system.
