The problem with the condition of the Solar Power Plant is still not optimal due to position of the solar cells in generator is still static so that absorption of light is still not even though Hybrid technology is now available but cannot be optimized properly and still cannot be optimized implemented especially in small scale and remote areas. Another problem that needs attention is the continued operation of installed Solar Power Plants (SPPs), considering the installation and maintenance of the plant requires high investment costs because the installation of solar panels requires a large amount of land and costs besides requiring qualified technical personnel to handle problems and monitoring plant conditions are needed quickly and accurately. From the description of the problem, the first step is to identify the technology used in the factory, the second is the need to design a new system to be able to solve important problems in the plant and the third is to build a computerized system that uses the Hybrid Method on the plant used. is a combination of Artificial Intelligence and Data Mining Processes so that it can present accurate data so that it can help and analyze plant performance, monitor and control plants remotely quickly by using Web Control.

The article considers the possibility of using the surface of various reservoirs characteristic of regions when allocating land for lowpower solar power plants in Uzbekistan. When implementing low-power solar power plants in Uzbekistan, a certain amount of land resources is required (for installing solar panels). From the point of view of respect for natural capital (saving land resources), the method of installing solar panels directly above the surface of water basins based on the corresponding maps of water basins is technically and economically effective. The methodological basis of the research is the results of researchers work on the problems of land relations and land management. In the research, a systematic approach to the analysis of land use has been chosen, in which a variety of tools were used to determine the essence of the analyzed phenomena, processes and patterns. In recent years, industry has been rapidly developing in rural areas of the Yangiyul district of Tashkent Province of Uzbekistan. In this regard, the problems of effective use of land resources, especially targeted use of irrigated land, has become urgent. This means that in the future there will be problems when allocating land for the installation of low-power solar power plants.

The abandonment of conventional sources in favor of energy from renewable energy sources (RES) has a global dimension, and the dynamic increase in the share of energy from photovoltaic systems in the energy mix of many countries results from the possibility of obtaining it both on a small scale (micro-installations) and as part of economic investments (photovoltaic power plants). The study aimed to assess the economic efficiency of 22 photovoltaic farms located in northeastern Poland. The research covered 5 solar power plants with a capacity of up to 799 kWp (I), 13 between 800 and 1100 kWp (II), and 4 installations of 1.98 MWp (III). The evaluation was based on net present value (NPV), internal rate of return (IRR), payback period (PP), profitability index (PI), accounting rate of return (ARR). Additionally, a sensitivity analysis was carried out regarding the value of economic indicators. The analysis shows that all studied PV farms are economically justified investments (NPV > 0) regardless of the adopted scenario. Solar power plants of the largest analyzed capacity (group III) resulted in being the most profitable ones, but no linear relationship between the level of productivity and profitability was established. Due to the large variation in terrain shape in northeastern Poland, landscape value and social benefits, which are difficult to assess, the support system for investments regarding the construction of photovoltaic power plants proved to be the most effective in group I.

Vietnam is a country of a great solar potential; solar technology is growing rapidly in Vietnam and investors are very interested in building solar power plants. Construction of the rooftop solar power stations can help owners reduce monthly electricity costs and even get economic benefits by selling excess electricity coming from a solar power plant (PV) to the utility grid. In this study, the design results of a rooftop grid-tied solar power station with the capacity of 26 kWp for a commercial building were introduced to have a basis to assess the operation ability of solar power station under solar radiation conditions in Hanoi city, Vietnam. The simulation results using the PVsyst program have made it possible to calculate the solar energy potential in Hanoi city, the power generation and efficiency of the grid-tied solar power station. Solar power has been applied in Vietnam since the 1990s but is mainly used for areas that were far from national power grid such as mountainous areas, islands. Small scale grid-tied solar power has been developed since 2010 and mainly is used for residential applications or small and medium scale consumers. The total capacity of electricity produced by solar power plants in Vietnam by 2017 was only about 8 MW; this value is very low as compared to the potential of solar power in Vietnam. This is due to the absence of the government support for the policy of developing solar power. In accordance with the current roadmap of raising electricity prices in Vietnam, construction investment of rooftop solar power stations is economically feasible while contributing to environmental protection and counteracting climate change phenomenon by reducing the amount of CO2 emitted into the environment.

This paper presents a performance study on a standalone solar photovoltaic system. The application of photovoltaic solar cells is increasingly prevalent in Indonesia. Indonesia is a tropical country, where throughout the year, get sun exposure. This condition strongly supports the use of photovoltaic solar cells as a source of electrical energy. Many small to large-scale solar power generation systems have been built in Indonesia. On a small scale in the form of a standalone system, solar power plants are usually used as secondary power plants, where primary power plants still come from state electricity companies. In this research, the analysis of the performance of solar power plants for standalone systems with a capacity of 400 Wp. Efforts to improve the performance of solar cells are made by using a mirror reflector. The results showed that the mirror reflector could increase the output power of photovoltaic solar cells.

Stirling cycle and Rankine cycle heat engines are used to transform the heat energy of solar concentrators to mechanical and electrical energy. The Rankine cycle is used for large-scale solar power plants. The Stirling cycle can be used for small-scale solar power plants. The Stirling cycle heat engine has many advantages such as high efficiencyand long service life. However, the Stirling cycle is good for high-temperature difference. It demands the use of expensive materials. Its efficiency depends on the efficiency of the heat regenerator. The design and manufacture of a heat regenerator are not a trivial problem because the regenerator has to be placed in the internal space of the engine. It is possible to avoid this problem if we place the regenerator out of the internal engine space. To realize this idea it is necessary to develop the Ericsson cycle heat engine. We propose theoretical model and design of this engine.
