Study on feed-in-tariff (FiT) for BIPV system, a Malaysia scenario

Abstract

Feed-In Tariff (FiT) was introduced in Malaysia in 2004 and has been undergone many stages to make its implementation in Malaysia successful. The first Building Integrated Photovoltaic (BIPV) introduced in Malaysia is Suria 1000 under the supervision of Pusat Tenaga Malaysia (PTM). The aim of this paper was to study the FiT and BIPV implementation in Malaysia. It is observed that Malaysian did not invest in BIPV due to its expensive investment. The FiT Calculator was developed to prove the benefits of FiT in BIPV by practically calculating the investment and profit in the long run which was after 21 years of implementation. FiT Calculator was developed using Microsoft Visual Basic 2010 and variable parameter such as the solar irradiation, types of solar panel and inverter were studied to obtain the estimation of power output, the annual income, net income and the payback period of BIPV. Results of all case studies were verified with MBIPV mileage report and the built FiT Calculator has shown up to 96.89% accuracy against the case study done.
