The solar PV systems are semiconductor devices that precisely convert sunlight into electricity, through the transfer of electrons. They provide several advantages, such as high modularity, zero noise, and adequate availability of solar resources in Indonesia. Therefore, this study aims to determine the potency, policy perspective, and Cost-Benefit Analysis (CBA) of the solar energy implementation for electricity generation. A statistical analysis was used for measuring potency, as well as reviewing opportunistic policies and barriers. A review of some CBA-based journals was also carried out, to determine that the development of solar power electricity had more benefit than fossil fuels and LCOE (Levelized Cost Of Electricity). The results of the 10-days average value calculation in 2019 were 388-563 W/m2, with the maximum values at 1137-1604 W/m2. Meanwhile the analysis of the maximum hourly averages for Western, Central, and Eastern Indonesia were 570-719, 634-758, and 559-627 W/m2 at 11.00-12.00 WIB, 11.00-13.00 WITA, and 12.00-13.00 WIT, respectively. The potency of solar radiation intensity in Indonesia was averagely 150-750 W/m2, as the highest values were found in East Nusa Tenggara, Maluku, and Merauke.

With the increasing global concerns about greenhouse gas emissions caused by the extensive use of fossil fuels, many countries are investing in the deployment of clean energy sources. The utilization of abundant solar energy is one of the fastest growing deployed renewable sources due its technological maturity and economic competitivity. In addition to report from the National Renewable Energy Laboratory (NREL), many studies have suggested that the maturity of solar energy systems will continue to develop, which will increase their economic viability. The focus of analysis in this paper is countries with hot desert climates since they are the best candidates for solar energy systems. The capital of Saudi Arabia, Riyadh is used as the case study due to the country’s ambitious goals in this field. The main purpose of this study is to comprehensively analyze the stochastic behavior and probabilistic distribution of solar irradiance in order to accurately estimate the expected power output of solar systems. A solar Photovoltaic (PV) module is used for the analysis due to its practicality and widespread use in utility-scale projects. In addition to the use of a break-even analysis to estimate the economic viability of solar PV systems in hot desert climates, this paper estimates the indifference point at which the economic feasibility of solar PV systems is justified, compared with the fossil-based systems. The numerical results show that the break-even point of installing one KW generation capacity of a solar PV system is estimated to pay off after producing 16,827 KWh, compared to 15,422 KWh for the case of fossil-based systems. However, the increased cost of initial investment in solar PV systems deployment starts to be economically justified after producing 41,437 KWh.

Driven by falling photovoltaic (PV) installation costs and potential support policies, rooftop PV is expected to expand rapidly in Thailand. As a result, the relevant stakeholders, especially utilities, have concerns about the net economic impacts of high PV adoption. Using a cost–benefit analysis, this study quantifies the net economic impacts of rooftop PV systems on three utilities and on ratepayers in Thailand by applying nine different PV adoption scenarios with various buyback rates and annual percentages of PV cost reduction. Under Thailand’s current electricity tariff structure, Thai utilities are well-protected and able to pass all costs due to PV onto the ratepayers in terms of changes in retail rates. We find that when PV adoption is low, the net economic impacts on both the utilities and retail rates are small and the impacts on each utility depend on its specific characteristics. On the other hand, when PV adoption ranges from 9–14% in energy basis, five-year retail rate impacts become noticeable and are between 6% and 11% as compared to the projected retail rates in 2036 depending on the PV adoption level. Thus, it is necessary for Thailand to make tradeoffs among the stakeholders and maximize the benefits of rooftop PV adoption.

A large potential exists in the Southeast Asia region for deployment of high-efficiency, low-emission (HELE) electricity generation technologies. A cost–benefit analysis of HELE technologies compared to the less efficient subcritical electricity generation plants is thus carried out to find a persuasive scenario supporting quicker transition from subcritical stations towards HELE technologies in the region. A levelized cost of electricity (LCOE) analysis is carried out for both technologies under four potential policy scenarios. Scenario 1 does not take into consideration any carbon pricing or costs associated with the desulphurization (deSOx) and denitrification (deNOx) facilities. Scenario 2 (Scenario 3) incorporates carbon pricing (costs associated with the deSOx and deNOx facilities), and Scenario 4 includes both carbon pricing and costs associated with the deSOx and deNOx facilities. Under each scenario, a sensitivity analysis is performed to evaluate the uncertainty affecting the future coal prices. This study demonstrates that HELE technologies are competitive against the subcritical plants under all four scenarios and both the technologies derive benefit from lifetime extensions and low coal prices. It is revealed that future deployments of HELE technologies can be best expedited by factoring in carbon pricing in LCOE costs of coal-fired power plants under Scenario 2.

<div><p>Evaporative cooler operating on solar energy is a viable option in places where there is scarcity of grid power and is also useful for short term storage of farm products. This paper analyzes the performance of a commercial cooler operated on the solar power and its cost benefit analysis. The cooler is operated on grid power in first part and on solar power in second part. The saturation efficiency, cooling capacity and the energy consumption is calculated in both the cases. The efficiency ranged from 41 to 70 %, cooling capacity from 4625 to 12079 kJ/h and energy consumption from 0.113 to 0.184 kW. The cost benefit analysis gives a payback period of about 11.5 seasons for the cooler if used for only comfort. If the cooler is used continuously for short term storage of farm products, then the payback period is estimated to be of 21.5 months. The optimization of solar panel, battery and inverter cost is suggested to have the early pay back of the investment cost. The cooler installation is recommended in place where there is shortage or frequent fluctuation of grid power.<em></em></p></div>
