The present invention provides a solar heat collecting device having good heat collection efficiency. A uniaxial solar-tracking reflective mirror group is arranged such that each longitudinal axis thereof faces the same direction. A first biaxial solar-tracking reflective mirror group and a second biaxial solar-tracking reflective mirror group are arranged lined up in a direction orthogonal to the longitudinal axis direction of uniaxial solar-tracking reflective mirrors. The uniaxial solar-tracking reflective mirror group is arranged so as to be sandwiched on both sides by the first biaxial solar-tracking reflective mirror group and the second biaxial solar-tracking reflective mirror group. Each mirror group sends solar heat received during uniaxial or biaxial tracking in accordance with the position of the sun, to a heat collecting device.

An optimally-angleable solar powered air system is a portable indoor solar heating unit that may stand upright or may be mounted to a door or window. The optimally-angleable solar powered air system has a frame having a solar panel mounted to a first side and a fan mounted to a second side of the frame. In use, the frame may stand inside a room at an angle facing the sun via a removable handle such that the solar panel is able to capture solar energy. The system may then convert solar energy into usable power to power the fan. The second side of the frame includes an air deflector which may direct airflow outwardly from the second side of the frame into the room.

A hybrid solar reactor and a heat storage system are disclosed. The hybrid solar reactor includes one or more heaters and a solar light guide assembly coupled to a shell of the reactor. The solar light guide assembly includes a solar light guide to direct solar energy to, for example, one or more reactor tubes within the shell.

The disclosed technology includes converting solar energy to thermal energy and delivering heat for use in a process. A representative method includes transferring solar energy to a working fluid and transferring energy from the working fluid to a heating element positioned inside a heating well. The heating well contains a thermal energy storage substance (TESS). A controller controls the heating element, which is in thermal communication with the TESS. In some embodiments, the TESS releases and absorbs heat as latent heat, which reduces temperature variation in heat exchange between the heating well and the formation surrounding the heating well. In such embodiments, the TESS is positioned between the heating element and an outer casing of the heating well. In addition to heating wells, the disclosed technology can be applied to other processes involving heat delivery.

A heating system is described that uses solar thermal technology in the heating cycle using the compression principle to reduce the electrical consumption of the compressors, thereby increasing the efficiency of systems being used for heating with an increased refrigerant flow. Thermal energy provided from solar thermal energy collectors may be used. The rate of efficiency of the total heating system depends heavily on the size and construction of the heat exchanger array and the pipework to and from these heat exchangers. The system uses proper dimensioning, components in the pipework, and logic groups with sensors and actuators attached in that pipework to increase energy efficiency.
