The present invention discloses a solar heating system for cyclic heating of a swimming pool, relating to the swimming pool heating technology. The solar heating system structurally comprises a swimming pool, solar heaters and a water pump. Compared with the prior art, a solar panel is mainly added, and the water pump is installed on a solar heater in an integrated way that the water pump is connected with not only the solar heater as a waterway, but also the solar panel as a power supply circuit. After the above-mentioned improvements, the whole solar heating system has the advantages such as a compact structure, convenient disassembly and assembly, and miniaturization. Since the solar panel independently supplies power to the water pump, the solar heating system can be used normally in an outdoor place far away from a mains socket. The application place is not restricted with wide application scope.

A screw anchor for a trussed foundation system to support single-axis trackers and other structures and related methods of driving such a screw anchor into underlying ground. A hollowed tube of uniform diameter is open at both ends with a thread form beginning at one end and circumscribing a portion the tube, the thread form having a tapered lead-in. The open-ended geometry allows a mandrel or rock drill to be inserted and operated through the anchor during driving to expedite the driving process. The tapered thread form provides a lead-in for driving the anchor into a rock bore.

A machine for rotary driving screw anchors into underlying ground and related. The machine has a mast with a rotary driver and a mandrel driver oriented on a common axis. The mandrel driver passes a mandrel through the rotary driver and the screw anchor to allow the mandrel to be actuated ahead of the screw anchor while the rotary driver drives the screw anchor into the ground. Alternatively, the mandrel driver may also drive a hammering drill through the screw anchor to clear a path ahead of it through subsurface rocks.

The present disclosure relates to an azobenzene-graphene metal coordination solar photothermal energy storage material based on metal coordination bonds and a preparation method thereof. The method comprises the following steps: preparing reduced graphene oxide; preparing an azobenzene-graphene material; and preparing an azobenzene-graphene metal coordination solar photothermal energy storage material: dispersing the prepared azobenzene-graphene material in DMF, dissolving a certain amount of metal compound in DMF, adding the DMF solution of the metal compound into the DMF solution of the azobenzene-graphene, taking out the precipitate, washing off metal ions which do not participate in coordination, and drying the obtained product to obtain the azobenzene-graphene metal coordination solar photothermal energy storage material. The present disclosure also relates to a method for improving the solar photothermal energy storage ability of a molecular solar energy fuel, comprising using an azobenzene-graphene metal coordination solar photothermal energy storage material.

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.

An autonomous solar module installation platform can be used for solar module installation onto a solar tracker. The autonomous solar module installation platform can include an off-road capable base vehicle and a robotic arm, mounted on the off-road capable base vehicle, for the solar module installation onto the solar tracker. The off-road capable base vehicle and the robotic arm can communicate with each other and cooperate their movements to proceed to the solar tracker and align with the solar tracker in order for the robotic arm to pick up and lift the solar module during an installation of the solar module onto the solar tracker.

In accordance with exemplary inventive practice, a catalytic system and a temperature swing adsorption system are thermally integrated. The temperature range of the adsorption system is lower than the catalyst operating temperature. Benefits of inventive practice include reduction of total energy consumption and of generated waste-heat. Total energy consumption is reduced by transferring some of the waste-heat generated by the catalytic system into the adsorption system during the sorbent heat-up portion of the sorbent regeneration cycle. The heat is transferred using a thermal reservoir, which accumulates heat from the catalytic apparatus and transfers it to the adsorption apparatus at a later time, and which is repeatedly cycled as the sorbent is cycled. The catalytic system and the adsorption system can be inventively integrated in various ways to reduce the total energy consumed, and/or to modify the sorbent regeneration temperature profile, and/or to obtain an optimum power load profile.
