The present invention relates to a solar collector (1) comprising a containment structure (6) with at least one face exposed to solar radiation, said containment structure (6) comprising a central housing recess (7) and an outer edge (8) that surrounds said central housing recess (7), inside said central recess (7) a primary conduit being arranged for the circulation of a primary heat transfer fluid, exposed to solar radiation, a secondary conduit for the circulation of a secondary fluid, and a heat exchange area between said primary and secondary conduit for the heat exchange between the primary heat transfer fluid and the secondary fluid, said solar collector (1) being characterized in that in at least one portion of said outer edge (8) of the containment structure (6) at least one dissipation conduit (9) is obtained in fluid communication with said primary conduit to dissipate the excess heat to outside said solar collector (1).

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.

An alignment tool for use with a solar panel support rack, configured to allow for the easy and rapid positioning of the support rack into proper alignment to receive solar panels.

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 invention relates to a solar surface receptor module that operates at a high temperature and comprises a channel (101) extending therethrough and along which a heat transfer occurs between a fluid (liquid or gas) moving in said channel (101) and at least one wall (104) of the receptor exposed to concentrated solar radiation, characterized in that the inner surface (105) of at least said wall includes turbulence-generating actuators (110) at the fluid inlet (102). The present invention also relates to a solar receptor therefor.
