A solar power system capable of storing heat energy and converting sun light to electrical power. The solar power system includes a solar collection system which gathers and transmits concentrated solar energy to an absorber/cavity. The thermal energy is extracted from the absorber/cavity via a fluid and transported to a heat conversion system. The heat conversion system uses the thermal energy to create electricity.
