A solar energy capture and conversion system for use on a roof of a building and to convert incident solar radiation to heat and electricity comprising: a mounting structure which supports a matrix 130 in which is embedded a conduit 150 containing a working fluid. The fluid or fluid mixture includes at least one hydro-fluoro-ether (HFE). First and second valves are arranged to open/close respective first and second ports which connect the solar energy capture system to a combined heat and electrical generating system. Also disclosed is an energy storage device (500, fig 3) comprising a sealed vessel containing a fluid channel (504, fig 4) arranged in parallel sections connected in series by U shaped sections. The fluid channels may include extended fins (508, fig 4) and the vessel is filled with a phase change material arranged to change phase to store or release energy. |
