The enhancement of solar power system implementation in LAS building

Abstract

This paper presents the techno economic analyses on the cost of upgrading the abandoned photovoltaic (PV) system that installed at the building of Legal Affairs Section (LAS), Putrajaya, Malaysia. System Advisor Model (SAM) software has been used to analyze the techno economic analyses of the proposed configuration of the new building integrated photovoltaic (BIPV) system. In this study, 4 study cases have been executed that considering different units of inverter and battery installations in the existing BIPV system. From the study, it was found that by maintaining the existing PV inverter system, but by adding one unit of battery may presents best option for this LAS building, where the operational and maintenance costs can be minimized better. Hence, it is projected that the intention to reach the target of making Putrajaya as a Green City on 2025 could be realized in the near future.
