“…In the case of solar thermal technology, the energy obtained from the solar source is directed to meet the requirements of different end-users in different sectors such as building, industry and residential sectors and applications ( Heng et al., 2019 ). For example, the building sector, including both residential and commercial, covers a wide range of purposes from cooking to water heating ( Naghavi et al., 2020 ).…”

COVID′19 pandemic has devastated several industries and solar energy is no exception. In its economic relief package, Malaysia has announced approximately US$ 2.9 billion in expenditure for the installation of new grids, LED street lights and rooftop solar panels. The Government will also open the tender for a 1400 MW solar power project in the year 2020, which is expected to generate 5 billion ringgit (US$1.1 billion) in investments. As these measures are intended to sustain the existing growth of solar energy potential in the country, it is vital to assess its status quo. Hence, this paper aims to review the current status of renewable energy in Malaysia as well as the initiatives taken before the pandemic to promote solar photovoltaic (PV) technology to meet the energy demands through the low-carbon pathway.

“…It also describes very mere difference in ambient temperature in June (28°C) and July (27.7°C) [ 39 ]. Similarly, another research describes Malaysia as ‘mere distinctive season country and its climate is hot and humid’ [ 40 ]. Due to the similar indices, we considered 5 days’ of dry climate data to estimate seasonal–based energy yield for peninsular Malaysia.…”

This study analyzes the performance of two PV modules, amorphous silicon (a-Si) and crystalline silicon (c-Si) and predicts energy yield, which can be seen as facilitation to achieve the target of 35% reduction of greenhouse gases emission by 2030. Malaysia Energy Commission recommends crystalline PV modules for net energy metering (NEM), but the climate regime is a concern for output power and efficiency. Based on rainfall and irradiance data, this study aims to categorize the climate of peninsular Malaysia into rainy and dry seasons; and then the performance of the two modules are evaluated under the dry season. A new mathematical model is developed to predict energy yield and the results are validated through experimental and systematic error analysis. The parameters are collected using a self-developed ZigBeePRO-based wireless system with the rate of 3 samples/min over a period of five days. The results unveil that efficiency is inversely proportional to the irradiance due to negative temperature coefficient for crystalline modules. For this phenomenon, efficiency of c-Si (9.8%) is found always higher than a-Si (3.5%). However, a-Si shows better shadow tolerance compared to c-Si, observed from a lesser decrease rate in efficiency of the former with the increase in irradiance. Due to better spectrum response and temperature coefficient, a-Si shows greater performance on output power efficiency (OPE), performance ratio (PR), and yield factor. From the regression analysis, it is found that the coefficient of determination (R2) is between 0.7179 and 0.9611. The energy from the proposed model indicates that a-Si yields 15.07% higher kWh than c-Si when luminance for recorded days is 70% medium and 30% high. This study is important to determine the highest percentage of energy yield and to get faster NEM payback period, where as of now, there is no such model to indicate seasonal energy yield in Malaysia.

This study employed simulation software to model the coal-based polygeneration systems (PGSs). The carbon-utilization ratios (η C ), hydrogen-utilization ratios (η H ), and energy-saving ratios (ESRs) were used to quantitatively analyze the performance of various coal-based PGSs. This analysis was based on two parameters: the unreacted gas circulation ratio (r) and the ratio of synfuel energy output to power output (λ). The results indicate that both r and λ a ect the η C , η H , and ESR values. Increasing r was found to increase element utilization and ESRs, and a better performance was achieved when a water-gas shift (WGS) reactor was utilized. The highest η C , η H , and ESR values obtained were 29.08, 37.89, and 17.68%, respectively. Increasing λ was also found to increase element utilization and ESRs. When λ 4 and both unreacted-gas circulation and the WGS reactor were employed, the highest element-utilization ratios (η C 19.59%, η H 37.78%) and ESR (19.78%) were achieved. In the corresponding case where a WGS reactor was not used, the η H value signi cantly improved over the range λ 0.0-2.0.
