Comparative Analysis between Net and Gross Metering for Residential PV System

Abstract

In this paper, comparative assessment of the previous feed-in tariff (FiT) and the new net energy energy metering (NEM) scheme for residential PV system in Malaysia is carried out. The study used two different load profiles of two different residential houses for fixed rooftop PV system. The analysis is performed by using Homer software. The electricity tariff for Malaysia is used to compare the FiT and NEM in terms of financial benefit to consumers. This paper considers several financial factors such as payback period, Net Present Cost (NPC) and Cost of Electricity (COE). For comparison, the similar analysis is conducted by using Electricity tariff in another country in Europe i.e. Portugal. The comparative results indicated that FiT provides better financial return as compared to NEM for residential consumer in Malaysia.
