1.2 Problem statement
In Malaysia, the government has encouraged people to increase the installation of PV systems among the residential and consequently introduced FiT scheme. The
combustion of fossil fuels such as natural gas, oil and coal produce the carbon dioxide which can be lead to acid rain and global warming. Therefore, generation of PV system has
beneficial to the environment which could be reduce the Green House Gas including carbon dioxide CO
2
emissions are relatively clear [4]. By installing PV plant system, customers will become like an investor since install the PV system such an investment
which could be earn the payback money from the generating power to the grid. Due to these various incentives will made grid-connected solar photovoltaic power systems to be a
great financial investments for many consumers. Payback period becomes a key investment decision indicator among the investors
in global. It can affect the generation of PV system, system performance and PV system energy cost. However, all of these parameters have not been analysed in Malaysia since
banker and other parties are still not familiar with the beneficial of PV installation. In addition, grid parity is important to be analysed due to economic crisis in a country such as
inflation or the rise of the electricity price on grid utility. Other than that, policy in a country and tariff degeneration could also affect the grid parity. Indeed, the generation of
photovoltaic systems to reach grid parity was become one of the most popular discussed topics in the world of renewable energy [1]. Thus, it is the most significant to have
accurate information of local electricity costs pricing schemes and usage. Therefore, a thorough understanding and make clear on what is the exact coming for the future after
grid parity is reached. All the factors should indicate and the financial risk can be avoided after predicted the year of grid parity.
