Our double-axis trackers are based on tried-and-true reliable design allowing for various adjustments and operational flexibility. The construction has been engineered to require minimum maintenance and operates fully automatically. The construction is projected as a separate entity carrying 16 (tracker type D16) or 30 monocrystalline Phono Solar panels for the D30 tracker. The main reason for the implementation of double-axis tracking systems is the possible increase of up to 30% of energy generated by the system with the investment increase required being only 50% compared to the fixed constructions. The construction is made of corrosion resistant steel and its motion is secured by two electric motors governed by central logic unit. According to the information obtained from solar sensors this unit coordinates panel surface tracking in accordance with the motion of the Sun. The logic unit is supplied by the ordinary network system with a voltage of 230V. Tracker engines usually operate only for 30-45 minutes a day. Their energy consumption is only 30-45 Wh. The tracker durability exceeds 25 years.
