Energy is one of the essential inputs for modernization and social development. Energy demand is increasing, and the primary energy source is fossil fuels, which negatively impact the environment. Energy saving and renewables are the potential solutions which could minimize environmental impact. This paper investigates the energy-saving and solar photovoltaic energy potential of an educational institution, Politeknik Sultan Azlan Shah (PSAS), Malaysia. The feasibility analysis was conducted by assuming that PSAS joined the Net Energy Metering (NEM 3.0) program, where PSAS, as a NEM consumer, has a tripartite supply agreement with renewable energy (SARE) with a distribution licensee known as Tenaga National Berhad (TNB). This paper focuses on zero capital expenditure (CAPEX) saving through a 20-year contract. This paper proposes a rooftop solar photovoltaic diagram using a NEM meter installed in the ring distribution system at PSAS. The estimated savings to be obtained by PSAS in the 20 years that the contract is in force are calculated based on the assumption that the installed solar system has a capacity of 688 kW. The maximum value of power generated by the system for a year is 990,720 kWh. The feasibility analysis found that the cumulative net savings estimate for PSAS based on the overall calculation for 21 years of solar use is RM 3,534,250. Meanwhile, the cumulative assessment of carbon emission reduction obtained in the same period is 14,559,760 kg CO2 or 14,559.76 tons of CO2, which would save 363,994 mature trees from being cut down.

Commercial grid-connected rooftop solar PV systems are widely applied worldwide as part of affordable and clean energy initiatives and viable long-term solutions for energy security. This is particularly true in a crowded city where space is a constraint and at the same time, there are unutilized rooftops. With the recently announced Net Energy Metering (NEM) 3.0, commercial buildings in Malaysia can apply up to 75% capacity of the maximum demand (MD), which can be connected to the grid. Apart from reducing electricity bills, the owner can offset energy for 10 years. This paper presents a design analysis with the details of the sizing of a rooftop PV system. The PVsyst software tool is used to estimate the energy produced by a 380 kWp system, and this study provides a financial analysis to evaluate the profitability of the system with a particular interest in commercial buildings under the NEM 3.0 policy, which has resulted in 8.4 years return of investment (ROI). PVsyst is a software used to size the PV system and provides technical, financial, and environmental analysis. This in-depth analysis could provide a useful case study for asset owners in deciding the way forward for sustainable energy production, cost saving, and combating the energy security issue, since Malaysia is blessed with an abundance of sunshine throughout the year.

Renewable energy (RE) policies have proven to be an effective tool for implementing RE. Despite various policies introduced, the RE deployment in Malaysia has been weak, especially individual RE uptake. Lack of policy support has been linked with inadequate policy awareness and information based on the knowledge deficit theory. This study investigates the support for the Feed-in-Tariff (FiT) and Net Energy Metering (NEM) policy of individual solar photovoltaic (PV) technology among landed residents in Malaysia and the effect of information provision on policy support. A Solomon-four-group design was employed to measure policy support and test the relationship between information provision and policy support using a set of Likert scale questionnaires and a poster of FiT and NEM policy prepared in layman's terms as an intervention. Results show that majority of the residents agree with the environmental mission of the policy, except for the reduction of fossil fuel usage. For the economic aspect, the residents prefer a fixed rate for RE produced and generally agreed that high electricity consumers should pay for the RE fund. However, residents were less enthusiastic about the percentage deducted from electricity bills and the 'high electricity consumer' baseline. There was a significant difference between items scores at pre and post-test when given the intervention, in line with the deficit theory. Therefore, policy information should be communicated strategically, focusing on thepolicy's social and economic components that have the greatest influence on Malaysians. [ABSTRACT FROM AUTHOR]
