The future of humankind is built on reasonable use of nature resources, among other, energy saving. The “green ideas” are implemented not only through the increased level of human awareness but mainly due to economic justification. Use of the alternative energy sources is becoming more and more topical all over the world. 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, among others.
