The system and method to maintain the temperature inside a building or house within comfort levels independently of the Grid. The system has a collector; an accumulator; and a transformer, which is the building or house. The method consists of transforming energy from solar radiation into thermal energy, accumulating that energy into an accumulator, and using that accumulated thermal energy to warm the internal environment of buildings or houses. One of its loops functions between dawn and sunset and includes only the collector and the accumulator; its second loop includes only the accumulator and the transformer and operates primarily between sunset and dawn. The collector uses a blackened surface to transform sun's radiation into thermal energy to warm air that is used to conduct the thermal energy throughout the system. The system can be built with inexpensive material; utilized in significantly isolated areas; and constructed and assembled on site.

The present disclosure solves the problem of solar energy capture and storage for solar power generating devices. This power system does not rely on batteries to accomplish energy generation during nighttime operating hours or during cloudy days. Solar energy is collected in a chamber equipped with opposing parabolic mirrors and a gaseous medium. The solar energy collector traps the majority of incoming sunlight and, through the processes of thermal radiation, heat conduction, and heat convection, converts said sunlight into useable heat energy. The heated gaseous medium is pumped to a Stirling engine for the purpose of conversion to mechanical power.
