    摘要: Solar tracker (1) for providing sun tracking to solar panels, and comprising: torsion beam (2), defining a longitudinal direction of rotation and rotating the solar panels; motor (4), with motor shaft (5); first gearbox (6), at torsion beam (2) at first position, and connected to motor shaft (5) for transmitting to torsion beam (2) rotation of motor shaft (5); second gearbox (7), mounted to torsion beam (2) at second position further from motor (4) than first position; and primary shaft (8), coaxial to motor shaft (5), and connected to second gearbox (7), for transmitting to second gearbox (7) rotation of the motor shaft (5). Gearboxes (6, 7) define embedments withstanding torsion moment caused by wind loads for restricting rotation of torsion beam (2). It provides higher resistance to wind loads and allows for longer solar trackers (1).

    摘要: The object of the invention provides a solution to the problem of connecting electrical systems in solar systems. Said solution is based on a a high power photovoltaic connector of the invention comprising two, preferably cylindrical, bimetallic connectors having a copper end and an aluminium end, being connected to each other by their copper end preferably in the form of a shovel making such a joint by means of tightening elements and to an aluminium conductor by means of its cylindrical aluminium end making such a joint by means of a tightening matrix or screws preferably furnished on the aluminium end. Said tightening matrix compressing the aluminium end and the aluminium conductor together due to deformation; being both the aluminium end and the aluminium conductor made of the same material with identical or very similar mechanical properties what the resulting tightening matrix achieves is to compress the aluminium end of the bimetallic connectors once the aluminium conductor has been inserted into it, so that the assembly is fixed due to the deformation of the aluminium.

    摘要: The invention relates to electric solar trackers moving solar panels and being controlled by a solar tracker controller. More precisely the object of the invention is aimed to a commissioning procedure of solar power plants. The invention accounts for a mesh communications network, multiple gateways respectively associated to each solar tracker controller; said gateways acting between the mesh communication network and a solar plant communications system wherein each solar tracker controller is assigned a unique serial number comprising ID, position on the solar plant of the solar tracker associated to said solar tracker controller. The gateway determining a solar tracker as being available for commissioning and sending configuration data to the solar tracker controller of said solar tracker available for commissioning, said configuration data including information of auxiliary gateways to connect to in case a primary gateway fails.

    摘要: The supporting structure comprises an omega-profile shaped metal support (3) with: horizontal upper portion (4), for vertically supporting photovoltaic panels (2); two flat lower portions (5) extending on both sides of upper portion (4), and connecting portions (6), connecting upper portion (4) with lower portions (5). Lower portions (5) include attaching holes (7) for attaching the lower portions (5) to ground through attaching means (8). Upper portion (4) and connecting portions (6) define inner hole (10) locating a gathering cabling (11) for gathering the electricity collected by each panel (2). The installation comprises photovoltaic panels (2) mounted on supporting structures. Preferably, albedo optimizing elements (21), attached to the metal support (3) are also included for improving capturing of albedo radiation. The invention helps to reduce foundation material, make mechanical and electrical contacts easier and raising gathering efficiency.
