COMPARISON OF MEASURED AND CALCULATED ELECTRICAL ENERGY CAPTURED BY PHOTOVOLTAIC PANELS

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.

STATE AND PROSPECTS OF SOLAR ENERGY DEVELOPMENT

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.

ALTERNATIVE HEAT SYSTEMS FOR MODULAR BUILDINGS

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.

ENERGY EFFICIENT SOLAR HEAT SUPPLY SYSTEMS FOR BUILDINGS AND STRUCTURES

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.

RESEARCH OF SOLAR COLLECTORS INTEGRATED INTO THE DESIGN OF THE BUILDING/STRUCTURE GLASS FACADE: NECESSITY AND FEATURES

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.

Analytical Studies of Coolant Temperature in Solar Panel

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.

Метод розрахунку параметрів системи сонячного теплопостачання із геліопанелями

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.

Енергетичний потенціал сонячної радіації на території України

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.

Теплова ефективність комбінованої геліосистеми в режимі протоку за південно-східного та південно-західного напрямку орієнтації

Solar radiation - is an inexhaustible source of renewable energy. Using solar energy is sufficiently promising to improve the environmental situation, reducing of consumption of fossil fuels, as well as for household and technological needs. Solar installations often are different design complexity or low rate of use of floor space, require complex electromechanical systems and mechanisms guidance. In addition to finding alternative energy sources, as opposed to traditional fuel.
