Solar power is a method in producing energy that is classified as renewable energy. Energy that comes from solar power, for now, has not reached level of commercialization due to the price of solar cells. In addition, this energy is affected by weather conditions, where the radiation intensity will get smaller when the sky is cloudy or rainy or during winter time. In order to minimize this weakness, a research project has been conducted to increase th e performance of solar power system by using liquid hydrogen as the working fluid. This method repaired heat or energy storage and can be used when sun radiation is dropped or not at all. Shortwave electromagnetic radiation from the sun will penetrate a transparent walls that made by tempered glass. Through this material, electronic radiation from the sun is transmitted into the interior space collectors. These collectors produce high heat inside the space, thus causing the occurrence of radiant heat transfer to the hydrogen pipes. Heat transfer from the hydrogen pipes into the hydrogen change its phase from liquid into vapor with high temperature and pressure. The results showed an increase in the capacity of energy generating by 40% and increasing capacity of storage energy by 45%.
