This article aims to present some opportunities for improved solar energy utilization by raising the share of renewables in energy generation in the Visegrád Countries (Poland, Czech Republic, Slovakia, and Hungary). The analysis is based on the status of the renewable energy targets in the member countries and their future possibilities. This paper derives input through a thorough investigation of independent data, government policies, European Commission reports, and other data available online with free access. The analysis is processed by focusing on Hungary, as a country with various possible facets of solar energy demand and supply in the region. The assessment methodology is in the context of a geographical map, technical regression analysis, temperature distribution profiles, and the relative trends of solar potential in Hungary. The country currently has ten solar power plants with more than 10 MWp, and five remarkable plants under 10 MWp capacity spread over Hungary. The analysis on geographical aspects clubbed with technical and solar affecting parameters was carried out to harvest the sustainable potential of solar energy in the region. This study attempts to establish a relationship between the current and future prospects of solar energy in Hungary as a nation, and as part of the Visegrád countries, based on assessment for a sustainable future.

Indonesia is blessed with abundant renewable energy resources. Nevertheless, they have only been used to cover about 5% of the total national energy demand.   To optimize their utilization, the government has to make and implement a policy that will encourage PLN costumers to help increase their on-grid power supply capacity. This policy will provide benefits for islands that are already equipped with PLN power grids. This paper uses Solar Power Plants and household costumers as models to calculate potential on-grid power increase which can be contributed by PLN costumers. A two-way power meter is used to replace the currently used one. This model will be applied to the  conventional grid to demonstrate the compatibility that show how it is applicable even without upgrading the conventional grid to become   smart grid system. The result shows that customers can participate significantly through the flow of their excess energy to grid.

The need for electrical energy in Indonesia continues to increase every year. In line with the increase in the electrification ratio to 100% in 2050, the demand for electrical energy is projected to reach 7 times, namely 1,611 TWh. To meet electricity needs, the government has created a 35 GW program, but one of the largest contributors to power generation fuel is coal with a share of 58% or around 50 GW which is estimated to be exhausted within the next 68 years. For this reason, innovations are needed in terms of fulfilling electrical energy by utilizing renewable energy potential, one of which is hydro energy, which is 45,379 MW from a total resource of 75,091 MW. Therefore, from this potential, innovations related to renewable energy have been created, namely the Hybrid Portable Underwater Turbine Hydro and Solar Energy hybrid power plant. This power plant uses an undersea current as a propulsion which is hybridized with solar power to increase the production of electrical energy. This power plant has the advantage that there is an Underwater turbine design that is resistant to underwater flow and a water flow direction to increase the work efficiency of the underwater turbine. From the test results, the portable Underwater turbine hydro produces 950 W in a day. Solar panels produce 65.6 Watts a day. The total hybrid that can be produced is 1.02 kW a day. In its implementation it can supply loads of up to 900 (VA) such as lamps, fans, TV, etc. This hybrid power plant can be a solution to help meet electricity needs in the area around Dusun Dongol, Sidoarjo through alternative electrical energy innovations.

Renewable energy use can mitigate the effects of climate change. Solar energy is amongst the cleanest and most readily available renewable energy sources. However, issues of cost and uncertainty associated with solar energy need to be addressed to make it a major source of energy. These uncertainties are different for different locations. In this work, we considered four different locations in the United States of America (Northeast, Northwest, Southeast, Southwest). The weather and cost uncertainties of these locations are included in the formulation, making the problem an optimization-under-uncertainty problem. We used the novel Better Optimization of Nonlinear Uncertain Systems (BONUS) algorithm to solve these problems. The performance and economic models provided by the System Advisory Model (SAM) system from NREL were used for this optimization. Since this is a black-box model, this adds difficulty for optimization and optimization under uncertainty. The objective function and constraints in stochastic optimization (stochastic programming) problems are probabilistic functionals. The generalized treatment of such problems is to use a two-loop computationally intensive procedure, with an inner loop representing probabilistic or stochastic models or scenarios instead of the deterministic model, inside the optimization loop. BONUS circumvents the inner sampling loop, thereby reducing the computational intensity significantly. BONUS can be used for black-box models. The results show that, using the BONUS algorithm, we get 41%–47% of savings on the expected value of the Levelized Cost of Electricity (LCOE) for Parabolic Trough Solar Power Plants. The expected LCOE in New York is 57.42%, in Jacksonville is 38.52%, and in San Diego is 17.57% more than in Las Vegas. This difference is due to the differences in weather and weather uncertainties at these locations.

Solar energy is the most important green energy source that may be used to address the problems caused by conventional energy sources. The research in this paper aims to evaluate the solar energy potential of M'Sila, an Algerian internal region, and to determine which technology, among those currently available on the market, is adequate for harnessing that potential for electricity production (PV and CSP). This assessment was based on data (daily temperature and daily solar irradiation) collected at M'Sila weather station for one year and from the NASA site for 34 years from 1984 to 2017. These data were treated with excel 2016 software to determine the total horizontal, diffuse and direct normal solar irradiation. During the study period, the total solar irradiation falling on a horizontal surface in M'Sila (GHI) was estimated to be 1.79 MWh/m2/year. The diffuse solar irradiation incident on a horizontal surface (DHI) and direct normal irradiation, respectively, were estimated to be 594.88 kWh/m2/year, 2117.93 kWh/m2/year. M'Sila is a favourable land for the installation of concentrating solar power plants and photovoltaic panels due to its significant potential energy. The parabolic trough system is recommended. While polycrystalline PV modules should be promoted and installed in M'Sila.

This study aims at mapping and evaluating the hydropower and solar energy potential in the Patimban area, Subang district, West Java Indonesia, within the vicinity of Patimban Deep-Sea Port construction. The hydrological model, the geographic information system (GIS), and climatology data were exploited to assist the estimation of the site-specific hydropower and solar energy potential. The results at hand reveal that the Patimban area exhibit a promising potential to develop both pico and micro hydropower plants for domestic energy supply in the urban area close to the seaport. Meanwhile, the solar energy potentials in merely 12 ha area determined from the sunshine durations in the Patimban area enable to adequately supply the approximated energy demand of the Patimban DeepSea Port operation. The financing scheme for funding this renewable energy power plant is briefly discussed and proposed as an alternative to the limited budget for the Patimban Deep-Sea Port construction. Overall, the hydrological model and GIS demonstrate their applicability in assessing the potential of environmental sources of renewable energy.

The research is aimed at analyzing and finding the reasons for the specific development of the solar energy market of Ukraine, defining the interaction on the part of the State and its role, furthermore the role of monopolists-generators and small generating equipment in private households. As result of the research, the following issues are considered: specifics of the formation of a share of the segment of solar power plants among renewable energy sources; the largest companies – solar energy generators in Ukraine; dynamics of changes in the «green» tariff and installed capacity of solar power plants over the past decade; development of the direction of small solar power plants installed by households and the largest generating regions of Ukraine by both the number and the installed capacity of the households’ SPP. Analyzing modern analytical reports on renewable energy generation, it is appropriate to note that a system of indicators, which is being created currently to reflect the real state of development of renewable energy, indicates a certain prospect of scientific research in this direction. Modern problems of development of the generating renewable energy market are defined, among which the following are defined: changes in legislation on the «green» tariff, which leads to changes in the investment climate and attractiveness of generation projects, the conflicting mechanisms of tariff auctions; potential threat of shortage of both storage and transport capacities (due to disproportionate development of generation volumes and its infrastructure support) etc. Based on the analysis of existing development trends, conclusions have been drawn about the future state and development of the solar energy generation market. The need to form a balanced national strategy for the development of renewable energy, taking into account the current conditions for reducing the «green» tariff and the cost of generating equipment, as well as taking into account the national interests of the State, the interests of monopolists and households, has been established.

Renewable energy is a solution for electricity generation for cleaner and green energy. The aim of this paper is to find the energy potential of India in terms of sources, per-capita energy consumption and the main potential consumers. Comparing consumption of fossil fuels and Renewable energy sources (RES) of India in 2019 and 2020 and finally to find whether there is any change in energy generation of two solar power plants in different geographical location of India with the help of independent t-test statistics. In this paper two statistical analysis are proposed. One is the statistical analysis of installed capacity, generation and consumption of fossil fuels and renewable energy in India. Other one is the statistical analysis of two solar power plants located at different geographical locations in India. From the statistical analysis it is found that, installed capacity of coal, RES and hydro is increased in 2020 as compared to 2019. Total demand in January 2020 is 2,77,140.33 MW whereas total installed capacity is 3,71,126 MW, this means that installed capacity is more but are not in running condition. From the statistical analysis of two independent solar power plants it is found that solar power plant-1 generates more energy but with high conversion loss hence poor efficiency.
