First, is described a methodology to let incorporate a low-precision, low-cost and 15 high-availability solar tracking mechanism and control system. The design methodology considers 16 the installation location (latitude and azimuth) as a starting point for establishing an adequate 17 angular range of EFO, simultaneity the aspects of available technology and the knowledge accords 18 to developer. Finally, the design technique is experimentally validated by the implementation of a 19 solar tracker at latitude of 28° longitude of 109° and evaluates the efficiency on a specific day. 20 According to result the feasibility of this type of solar tracker for latitudes close to or greater than 30° 21 is highlighted, given that this tracking system costs 30% less than traditional commercial systems as 22 slew drive with its incorporation of lower-resolution azimuth tracking mechanisms. It also increases 23 collection efficiency by 26%, just as continuous or time-based dual-axis solar trackers do, without the 24 more complex controls and mechanisms of these designs. 25
