Large solar thermal power plants are always using concentrators thus requiring tracking of the sun with a very high accuracy. Precision in the order of 0,0003° is required for both azimuth and elevation and this can be achieved by using ABB's AC500 PLC's and sophisticated NREL-SPA algorithm included.
ABB's product portfolio for solar thermal power plants includes all key components, such as drives, motors, PLCs and other low voltage products.
