Because III-V group solar cells can absorb direct sunshine within only an angle of 0.3˚~0.8˚, high-precision 2-axis tracking control system has to be applied in order to achieve the best efficiency of solar power generation. The content of this research is based on the Solar Position Algorithm (SPA) and uses a Delta PLC to develop the automatic tracking system. The demonstration specifications require that elevation operates between 0 to 70 degrees and azimuth rotates in the range of 270 degrees. In outdoors testing, the initialization of solar tracking system requires a level meter for horizontal positioning, and a compass for the orientation. The high precision angle measurement equipment, together with the SL1 sensor from Green Mount have been used to interpret deviation angles. Experimental data shows that this developed 2-axis solar tracking system can achieve an average track deviation angle less than 0.3˚ (±0.275˚ in elevation, ±0.0087˚ in azimuth) and satisfied the original design goals (accuracy of 0.3˚). Using the system developed by this study, HCPV with the acceptance angle of 0.5˚ can be applied in the future design of high precision SPA based 2-axis automatic solar-tracking system. Stephen P.
