Abstract: The invention provides a solar power system for use as a solar roofing concept based on an absorber system with a solar thermal absorber and a circulation system for circulating absorber liquid through the absorber and a core system which extracts energy from the absorber liquid and provides hot water to a building. An intelligent controller uses data about external conditions to control the core system, where both current conditions and predicted conditions are taken into account. In preferred embodiments, the system can generate heat, hot water and electric energy to cover the need for a normal household. When excess heat is generated, the thermal energy can be used by an organic Rankine cycle (ORC) machine for electricity production. A forecasting and control unit using external weather measurements in combination with internet weather forecasts will by fuzzy logic calculate the optimum periods of time for use of the heat pump during the colder periods.
