Abstract
The efficiency of a photovoltaic (PV) system will be greatly influenced by two factors: the effectiveness of the photovoltaic panel and the effectiveness of the electronic charging circuit. Since the PV panel efficiency has been controlled at the manufacturer level, the improvement in effectiveness of the electronic charging circuit is the solitary choice on the researcher side to improve the overall PV system efficiency. This paper proposes a novel design, development, and performance evaluation of a MPPT-based two-stage battery charging scheme that enables efficient battery charging. The street light with a capacity of 20 W has been associated with this proposed system and can function powerfully by the employment of an Automatic Luminous Control Mechanism. The experimental outcomes demonstrate that the suggested scheme with MPPT charger scores an average improved outcome of 10–15% better than a system without MPPT charger. These experimental studies also highlight that the battery back time could be improved because of the employment of an automatic light intensity control mechanism.
