The objective of the research is to develop hybrid solar system supplying air steam as well as electricity. By using cold mirror, the sunlight can be separated into ultra red and visible rays. Ultra red is reflected to solar panel, and visible rays are concentrated to heat solar collector. So, the high-coefficient system is able to realize. To concentrate the sunlight, semi-cylindrical type of non-imaging Fresnel-Lens is designed. The experimental results show that the lens efficiency is about 80%. And heat collector characteristics are found by heat collecting experiment. This characteristics show that the efficiency of this system is better than that of conventional system. It is also proof that it is possible to produce air steam with small medium flows.
