solar energy

Today, among renewable energy sources, solar power is particularly effective. It is known that solar panels are mainly (more than 95%) based on monocrystalline or polycrystalline (sometimes amorphous) silicon, as a unique semiconductor material. Its irreplaceability is explained by its prevalence in nature. at the same time, the technology of manufacturing silicon solar cells is quite complex and energy-intensive.

Energy independence remains a priority task for most European countries. Along with traditional energy sources, more and more attention is being paid to renewable energy usage. The best solution for city residents is the use of solar energy for the local needs of individual households. However, chaotic installation of solar panels on the roofs has a negative impact on the aesthetic qualities of urban environment. Many problems as well arise during installation of panels itself on the roof structure.

Increasing the efficiency of solar heat supply systems is one of the important problems of solar energy. The research presented in this article is aimed at improving the efficiency of hybrid solar collectors without a transparent coating for building heating systems. One of the key challenges in the field of solar energy is the development of new technologies to ensure high collection of solar energy and to integrate it into traditional heating and hot water systems.

The main goal of the work was the measurement of photovoltaic panels on a family house in the village of Lucka in eastern Slovakia during 4 months. The panels were mounted on the south side of the building at a slope of 26 degrees. The measurement took place every day only during sunshine. Subsequently, the comparison of these actually measured values with the calculated values from the PVGIS software, which also serves to calculate photovoltaic panels. Photovoltaic panels were measured in the months of April, May, June, July in 2021.

The potential of solar energy in Ukraine is high enough for widespread implementation. The most promising method of obtaining electricity is a method of direct conversion of radiation into electricity using solar panels. The production of electricity using solar panels prevents air pollution compared to the production of electricity by thermal power plants and reduces greenhouse gas emissions.

At present, the problem of energy-saving construction remains extremely relevant. The use of alternative energy sources for heat supply of buildings and structures is one of the ways to solve the problem of rational use of fuel and energy resources.

This article considers effective methods of using solar energy with the help of thermosyphon solar collectors integrated into the external enclosing structures of a modular house.

Today, the energy sector of Ukraine requires significant consumption of traditional energy sources (oil, gas, coal, nuclear energy). However, their use is associated with a number of difficulties, including thermal, chemical, and radioactive contamination of the environment and the exhaustion of their reserves. The paper is devoted to solving the actual problem of improving the efficiency of solar heat supply systems with solar collectors. An analysis of the potential of solar energy and existing solar heat supply systems is presented.

The work is devoted to the analysis of the need for the development of solar collectors integrated into the design of the building / structure glass facade. In particular, the necessity for Ukraine to develop renewable energy sources through the parameter of energy intensity of the Ukraine gross domestic product and the physical wear of the installation in fuel-energy complex. It was analyzed that the solar energy as one of the types of generally available resources in the field of alternative technologies has been prospects for development.

An analysis of existing solar heating systems has been carried out. The dependence of the annual flow of solar radiation on the solar panel on the azimuthal angle γ and the angle of inclination of the surface, which can be used for studying surfaces with an arbitrary number of orientations, was obtained. The thermal balance for a given solar panel is presented for a certain period of time.
