Economic Analysis Using Net Present Value and Payback Period: Case Study of a 9kWp Grid-Connected PV System at UTM, Johor Bahru Campus
An economic study for the photovoltaic (PV) projects by the PV installer is essential to avoid the risk that may incur from the investment. This paper discusses the economic analysis of PV installations specifically for the grid connected (GC) systems. The case study is the 9 kW Solar-Home UTM system which is planned to be a showcase GC zero energy house. The house will be able to sell the excess energy back to the grid according to the Malaysian Feed-in Tariff (FiT) implemented in 2012. The economic study conducted is based on the Net Present Value (NPV) and the Pay-Back Period to determine the profitability and viability of the project. The study is believed to encourage and initiate the public to build a successful investment and contribute in the development and deployment of new clean energy sources.
