Anotācija Introduction Today, solar energy is used both for generation of electricity and for production of hot water and air. The system’s costs for generation of any of the above mentioned processes are high. Methods Methods Households basically use systems operated by solar power for generation of electricity and hot water. However, it is exactly the heating that accounts for the largest part of costs incurred by households. The market offers hot air generation systems operated by solar power already now. Use of the said systems in the conditions of the temperate climatic area provides only for seasonal energy generation options. Combination of the solar energy systems, which generate hot air and hot water, permits operation of these systems throughout the year, thus increasing the system efficiency. Solar energy systems that generate hot water are currently being rather widely used. If such a system is installed separately its costs are high and its yield is long-lasting. Installation of a hot air generating solar energy system, in its turn, provides only for limited use depending on the seasonality because in summer air heating is not necessary. A market research showed that solar energy systems providing for simultaneous generation of hot water and hot air that would suit our climatic conditions are not available currently. Creation of a combined system will permit its use throughout the year, providing in its turn 100% use of sunny days for energy generation which is very important in our weather conditions. Today, the market offers only combined electricity and hot air generation solar energy systems basically intended for use in industrial objects. Considering the abovementioned, the research project plans to develop a new product – a combined hot air and hot water generation solar energy system usable in households. The project includes the industrial study and experimental development, and building of a prototype. The aim of the research is to conduct an industrial study and experimental development to work out a prototype of a new product - a combined hot air and hot water generation solar energy system usable in households. Conclusions The hot air and hot water generation solar energy system usable in households to be developed is a new product not only in Latvia. The new system will differ from the systems available on the market with that it could provide for simultaneous generation of hot air and hot water from solar power, thus increasing the building’s energy efficiency and decreasing the costs of use of the traditional energy, permitting use of the new system all around the year regardless of the season. Presently there are only the combined electricity and hot air generation solar energy systems available on the market intended basically for industrial use.
