A solar energy capture, conversion and storage system for use on a roof of a building for capturing and converting incident solar radiation to heat and electricity. The invention provides an optimised solar energy capture and conversion system that monitors immediately available incident radiation comprising a mounting structure which supports a matrix in which is embedded a conduit containing a working fluid. The fluid or fluid mixture includes at least one hydro-fluoro-ether (HFE). Valves are arranged to open/close ports which connect the solar energy capture system to either a combined heat/electrical generating system or an energy storage system that incorporates a phase change material to store heat energy. Control of the valves is supervised by an energy management system.

The invention discloses an efficient solar flat plate heat absorption system, composed of a primary circulating pipe network, a secondary circulating pipe network and a control system, wherein the primary circulating pipe network is formed by communicating a pipeline in a pressure bearing water tank with a heat exchange tube I in a flat plate heat collector group through a pipeline I and a pipeline III, the secondary circulating pipe network is formed by communicating a pipe network at the bottom of a swimming pool with a heat exchange tube II in the flat plate heat collector group through a pipeline II and a pipeline IV, wherein thermometers are arranged at a water outlet of the heat exchange tube I, at the water outlet of the heat exchange tube II, in the swimming pool and in the pressure bearing water tank, and circulating pumps are arranged on the pipeline I and the pipeline II. The invention makes full use of the heat energy by using the two circulating pipe networks formed by the parallel double heat exchange tubes in the flat plate heat collector group to realize the automatic and constant-temperature heating of the water in a swimming pool and avoid the water temperature in the swimming pool fluctuating suddenly, meanwhile the redundant heat can be recycled, thereby making full use of energy, saving resources and having obvious social and economic benefits.

Heat transfer between a fluid-bearing flexible tube and a heat-conducting surface is improved by fixing a flexible heat-conducting sheath to the flexible tube and by compressive fixing that distorts the tube and deforms the sheath and/or the surface. The tube can be made of cross-linked polythene (PEX). The sheath can be spirally wound high-purity aluminum wire. The sheath enables efficient heat transfer between the outer surface of the tube and the heat-conducting surface. Applications include radiant heating and cooling. Tube layout can be customized and variable tube spacing is possible, for example by using a castellated layer to support the tube.
