A building-integrated solar energy system is disclosed that comprises an evacuated closed-loop conduit network circulating a working fluid through a solar thermal collector and at least one heat usage device, wherein the effective entirety of the surfaces of the closed-loop conduit network are in contact with the working fluid such that phase change occurs whenever heat energy is added by the solar thermal collector or removed by a heat usage device. The working fluid is adiabatically isolated and contained in a low pressure environment within the closed-loop conduit network. The full surface contact and low-pressure isolation of the working fluid dramatically reduces temperature differentials and energy losses, allowing for highly efficient and cost-effective heat collection and distribution.

A concentrated solar power storage system and method convert water into water vapor by the solar thermal energy, and the water vapor further operates a hydroelectric power generation system with a water storage (or an energy storage capsule) through a repeated conversion process.

A building-integrated solar energy system that concurrently provides space heating, space cooling, hot water, and electricity to commercial and residential buildings. The solar energy system comprises an evacuated closed-loop conduit network circulating a working fluid through a solar thermal collector and at least one heat usage device, wherein the effective entirety of the surfaces of the closed-loop conduit network are in contact with the working fluid such that phase change occurs whenever heat energy is added by the solar thermal collector or removed by a heat usage device.
