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.

Виконано аналіз існуючих систем сонячного теплопостачання. Отримано залежність річного надходження  сонячної радіації на геліопанель від  азимутального кута γ і кута нахилу поверхні, яка може бути використана для дослідження поверхонь із довільною кількістю орієнтацій. Представлено тепловий баланс для даної геліопанелі за певний проміжок часу. Досліджено залежності для визначення кількості енергії, що надходить від Сонця на кожну із поверхонь геліопанелі та кількості тепла, закумульованого геліопанеллю.

Known methods of hot water systems was analyzed. Method of calculation of solar heating of heliopanels was proposed. Algorithm for computer calculation of solar heating of heliopanels was developed. Taken into account the impact of direct and diffuse solar radiation on the efficiency heliopanel.

Solar radiation – is an inexhaustible source of renewable energy. The energy of sunlight can be used as heat. Scientists have studied that ¾ of the total energy consumed by society is the heat energy. Solar installations designed to convert solar energy into other forms of energy and transfer it for future reference. The efficiency of solar installation depends largely on the amount of incoming solar energy, which depends on the geographical characteristics of the region for which planned to install solar installation. This paper deals with the use of solar energy solar installation.
