Abstract: A solar collector system for converting solar radiation to thermal energy and electricity has an upper cover with a material that is transparent to solar radiation. A solar energy absorbing structure is disposed under the upper cover and has a heat conducting material such as metal. In addition, a first heat transfer system is disposed in contact with the solar energy absorbing structure and has a material that transfers heat from the solar energy absorbing structure to a first substance flowing within the first heat transfer system. The solar collector system also has electric cells that absorb solar radiation and convert it into electricity. The cells are configured and disposed on at least a portion of the upper cover.
