Potential of Harnessing Green Electricity Using Photovoltaic Modules on Pitched Rooftop Using DC-DC Boost Converter

Abstract

This paper explores the potential of harnessing renewable energy through the use of photovoltaic modules installed on pitched terrace roofs in Malaysia, employing the eco-roof concept. Utilising typical climate data from Malaysia, the study investigates a system designed to charge a 339 V based battery storage system to estimate electricity generation and potential cost savings for residential homes. The series configuration of the PV rooftop connected to the boost converter charging circuit demonstrates favourable output characteristics and is deemed suitable for the charging application. A case study involving 150 houses per residential area reveals that the ratio of households contributing to and benefiting from electricity consumption and savings is 15:1. In summary, for every 15 houses charged to the designated battery system, one house can access the stored energy for daily use.
