A double line focusing solar energy collection apparatus of the present invention includes a heat collector, a secondary concentrator, and a bracket. The heat collector includes a primary concentrator and a heat collection tube, in which the primary concentrator has a focus line. The secondary concentrator has a focus line. The bracket supports the primary concentrator, the heat collection tube, and the secondary concentrator. The heat collection tube is located between the primary and secondary concentrators and located on the focus lines of the secondary and primary concentrators. The primary concentrator is a paraboloid reflector or Fresnel reflector. The secondary concentrator is a paraboloid reflector or Fresnel reflector. By adding the secondary concentrator, it achieves low light loss and high heat collection efficiency, and erosion of the heat collection tube by sand, rain, and snow can be effectively prevented, thereby extending the lifetime of the heat collection tube effectively.

In various representative aspects, an assembly for securing a solar panel rail and rail-less support structures to a shingle roof. More specifically, the apparatus includes a connection bracket and flashing device for use in installing solar panel rail support structures. The connection bracket is secured to the flashing device by rotating its base around a threaded connection until it locks in place so that a solar panel rail support guide can be connected to a generally U-shaped connection on the top of the bracket. The apparatus also offers an improved means to cover the penetration point on the flashing to protect it and prevent water from leaking into the roof as well as an improved way to install the apparatus over existing products. An alternate embodiment of the apparatus is offered to support a rail-less pivot mount as well.

A telescopic guide assembly for bridging a first solar panel table and a second solar panel table is disclosed. The telescopic guide assembly may include an inner pipe partially disposed within an outer pipe. The inner pipe may be configured to rotate within the outer pipe and may be further configured to partially slide-in or slide-out of the outer pipe. The telescopic guide assembly may further include a first coupler configured to mechanically couple the inner pipe with the first solar panel table at an associated first position on an inner side of the first solar panel table facing a second solar panel table, and a second coupler configured to mechanically couple the outer pipe with the second solar panel table at an associated second position on an inner side of the second solar panel table facing the first solar panel table.

A gas receiver configured to heat a working fluid is disclosed. The receiver comprises an aperture, a light absorber, and a pre-heater interposed between the aperture and light absorber. The pre-heater is transparent to visible light and opaque to infrared. The pre-heater in the preferred embodiment comprises quartz in the form of a plurality of quartz plates or quartz tubes, for example, that are oriented substantially parallel to one another. The quartz plates are separated from one another by a gap to permit air to pass into the receiver cavity, while the quartz tubes are hollow to permit air to pass therethrough. The quartz plates or tubes are configured to transmit visible light from the aperture to the light absorber, and to absorb infrared radiation passing from the light absorber toward the aperture. Since the quartz structures absorb infrared, they serve to capture blackbody radiation emitted from the absorber and use that energy to pre-heat air before it passes into the absorber.

The disclosed embodiments relate to a dismantling device configured for a frame of a PV module. The dismantling device includes a connection portion, a first holding portion, and a second holding portion. The first holding portion is connected to the connection portion and configured to press against one of an inner wall and outer wall of the frame. The second holding portion is slidably disposed on the connection portion and movably closer to or away from the first holding portion along a sliding direction. The second holding portion is configured to press against the other one of the inner wall and the outer wall so as to clamp the frame with the first holding portion and to distort the frame.

A cable hanger including a body defining a support coupling and a number of supported element couplings. The support coupling is a rigid element support coupling.

A system and method for the removal of volatile components from a liquid or a slurry containing solids and liquids and using a screw conveyor or auger system that transfers solid/liquid slurries through an elongated tube heated by solar energy from a parabolic solar trough. The system flashes off the volatile component then counter-currently flows that vapor back into the hollow pipe inside of the augur creating a Multi-effect or Multi Flash device which greatly improves the overall efficiency of removal of the volatile material.

A self-propelled robot that self-travels on a structure having a flat surface to perform a cleaning operation, the self-propelled robot includes a robot main body (2), a controller (30) that controls movement of the moving unit in a forward direction and a rearward direction, an operation unit (12a) that is controlled by the controller, and a pair of detection units that are first and second detection units, each of which functioning to detect if there is the flat surface of the structure beneath the detection unit. Wherein, seen from a top view of the robot, the first detection unit and the second detection unit (31a, 31b, 31c, 31d) are both arranged at the front end of the robot.
