A solar energy particle receiver system and method of use for precise and controlled heating, sintering, and/or phase change of particles. In one embodiment, the solar energy particle receiver system directs sunlight from a primary concentrator into supplemental concentrating reflective optic where the emitted sunlight is used to heat and sinter, melt, or induce a phase change of the particles such as regolith at a controlled temperature, the supplemental concentrating reflective optics cooled to prevent overheating and a sweeping gas directed at the reflective surface to prevent optical fouling. In one aspect, the supplemental concentrating reflective optic is a compound reflective concentrator. In one application, the particles are a regolith, such as a lunar regolith.

A protective transparent enclosure, such as a greenhouse, encloses a concentrated solar power system having line-focus solar energy concentrators. The line-focus solar energy concentrators have a reflective front layer, a core layer, and a rear layer. The core and the rear layers, when bonded with the reflective front layer, enable the line-focus solar energy concentrator, in some embodiments, to retain a particular form without additional strengthening elements. In some embodiments, the core layer and/or the rear layer are formed by removing material from a single piece of material.

A novel method is described for water heating using stored solar heat. Solar heat is stored in an insulated tank by using scrap and inexpensive heat absorbing or heat storing materials. Stored solar heat can then be used to heat water in a storage tank by extracting the solar heat using an antifreeze liquid which in turn heat cold water in the water tank. Water temperature in the storage tank is controlled by a thermostat. When the water temperature drops below the set point on the thermostat, a circulating pump turns on and pump the cold water until it reaches the desired set temperature. Once it reaches the set point in the thermostat, the water circulation pump turns off.

The present disclosure is directed to a solar receiver having improved heliostat field control. The solar receiver includes a plurality of receiver panels arranged adjacent to one another. Each receiver panel includes a plurality of receiver tubes aligned tangentially to one another. Further, each of the plurality of receiver tubes includes an inlet and an outlet.

An integrated wind and solar solution is provided, including a solar energy collection assembly (100) and a vertical axis wind turbine (400), combined to provide an integrated power output. In preferred embodiments, the vertical axis wind turbine is positioned above the solar energy collection assembly. Concentrating solar mirror collectors (116) are used to direct sunlight to a heat engine (250), which converts the collected heat energy into rotary motion. Rotary motion from the heat engine and from the vertical axis wind turbine preferably are on the same rotating axis (600), to facilitate load sharing between these two sources. A dual axis azimuth-altitude solar panel alignment tracking system is used in order to boost the energy conversion capability of the solar energy collectors.

A steam outlet end of the solar steam generator is connected to a steam inlet of the turboset. A steam outlet end of the external steam regulator is connected to the steam inlet of the turboset. A steam outlet of the turboset is connected to the input end of a condenser, and the output end of the condenser is connected to the input end of a deaerator. The output end of the deaerator is connected to the input end of a water feed pump. The output end of the water feed pump is connected to a circulating water input end of the solar steam generator. The output end of the water feed pump is connected to a water-return bypass of the external steam.
