This is the new 146 m2 heliostat developed by ACCIONA and TEWER. It has been optically tested and certified at the CIEMAT facilities at the Plataforma Solar, Almeria (Spain). To optimize performance and optical quality, while reducing cost, development has included standardization of design, manu-facture, and assembly. It is modular, so can be adapted to any terrain, even seismic or highly erosive areas. Its 32 facets are made up of highly reflec-tive solar mirrors supported by three linear profiles, with a tension-free mounting and edging system that minimizes error. It simplifies the torsion system, allows it to be manufactured in a single piece and includes an intel-ligent control that reduces calibration times. Mobile drives are electromag-netic, reducing maintenance. It contributes to the resistance, reliability, and performance of solar fields, to decarbonization and to the competitiveness of this renewable source. HOW IT WORKS during the construction phase, the warehouse and the assembly line must be designed to maximize the daily production of heliostats, as well as the logistics of transferring them to the solar field.” The RDI area improves the specifications and reduces the costs of all its components, especially the facets, or panels of the mirrors. “The mirrors require extreme optical quality, and at the same time rigidity, to withstand the wind without affecting their curvature - or in other words, their precision when concentrating solar radiation —explains Gallego — or without affecting the pedestal drives that gui-de the heliostats.” “The panels and supporting structures must be rigid; the automa-tic calibration solution governing the zenith and azimuth actuation (angle of orientation with respect to the surface of the globe) is con-tinuously aware of the position of the heliostat and applies data pro-cessing and intelligent algorithm to control and modify solar trac-king,” adds the expert.
