Abstract:
The article analyzes the advantages and disadvantages of solar energy as one of the main types of alternative energy. The author considers availability, ease of installation, low operating costs and technological development as key factors in the popularity of solar energy. In addition, the advantages of solar energy over other forms of alternative energy, such as the absence of noise, compactness and energy independence, are emphasized. A patent review is presented in which the authors analyze more than 80 patents related to solar energy and group them into clusters according to areas of improvement, such as reducing the cost of technology, increasing the availability of technology, simplifying the production process, increasing the efficiency of the element and safety and environmental friendliness. The conclusion emphasizes the importance of innovations in the field of solar energy to create more reliable, economical and highly efficient solar cells, which ultimately leads to an increase in their competitiveness and expansion of their application in the energy sector.

Abstract:
The paper examines the advantages and disadvantages of wind energy, focusing on the dependence of wind turbine efficiency on weather conditions, impact on the ecosystem, noise and visual impact. Patent analysis reveals another key problem of wind turbines – their inoperability in weak wind or its absence. Various patent solutions to this problem are considered, including a proposal to combine wind turbines with diesel generators and energy storage devices. However, each solution has its own disadvantages, such as high initial costs, noise, environmental pollution and safety risks. A patent solution in the form of using magnetoelectric generators and special blade shapes to improve aerodynamic efficiency is also considered. In general, the work emphasizes the need for further research and development in the field of wind energy to solve existing problems and improve its efficiency.

Abstract:
The paper considers the need to develop alternative energy in Russia in the context of growing demand for energy. The main attention is paid to solar, wind and hydropower as the most promising energy sources. It is noted that there is a shortage of alternative energy facilities in the country, despite favorable natural conditions for their development. The lack of appropriate building codes and regulations (SNiP) for the design and installation of alternative energy plants is analyzed, which creates gaps in the regulatory documentation. The paper compares existing studies and regulatory documents, such as SNiP 23-01-99 and GOST R 55260.1.8-2013, revealing discrepancies between recommendations and the actual placement of power plants. The results show that many areas with high potential for renewable energy remain underdeveloped. The conclusion highlights the need to improve the regulatory framework to support alternative energy in Russia, which can lead to improved energy independence and sustainability in the country.

European Journal of Renewable Energy. 2024. 9(1): 17-23.
Abstract:
Solar energy is a direction of alternative energy based on the direct use of solar radiation to produce energy in some form. Solar energy uses the Sun, a renewable energy source, and is ―green,‖ meaning it does not produce harmful waste during its active phase of use. Energy production using solar power plants fits well with the concept of distributed energy production. Modern methods of improving the efficiency of solar panels through innovative design solutions and materials are reviewed and analyzed. An analysis of the current state of developments and innovations in the field of solar panels in patents is also presented, and options for solving possible problems are proposed to minimize existing problems. The focus is on patents filed in the last seven years to identify key trends and research directions in this area. Patents relating to materials used to make solar cells, production technologies, and methods for improving the efficiency and durability of solar panels were analyzed. The findings help identify promising areas for further research and development of new technologies that will contribute to the development of more efficient and cost-effective solar energy solutions.

6. Semyon D. GavrilovEuropean Journal of Renewable Energy. 2024. 9(1): 24-27.
Abstract:
The paper examines the selection of a solar generator for an autonomous farm in Udmurtia. The Russian Science Citation Index contains 137 patents on this topic with a history of up to 25 years. After preliminary analysis, patent RU 2662244 C1 "Solar Generator and Method for Converting Solar Radiation into Electricity" was selected for design development. It is a promising technology that is characterized by potentially high efficiency, operation in a wide temperature range, and a relatively simple design. This makes it a suitable option for many remote areas with limited access to power grids. Further research and development in this area may lead to commercially viable solutions to meet the growing need for renewable energy sources.
