This system can be operated in parallel with power grid or independently. This system may provide an alternative solution for insufficient capacity of grid power. The experiment setup of this work is to integrate an independent solar tracking system, an energy storage battery system, and a hydrogen production electrolyzor. The solar tracking system was designed to sustain itself as possible, thus the motor is powered by the system. The angular error can be controlled within 0.5 degree by adopting the time-sharing operation. A 90kAh capacity of energy storage battery is used to store solar power generation, and to discharge during night time. The results showed that the overall efficiency of the solar tracking system was improved up 9%-24%, because of storing the abandon power in the energy storage system. For example, the specific solar radiation amount is 55.3kWh, and 4.32 kWh was stored in the energy storage system, and that is efficiency of 7.81%. As the hydrogen production electrolyzer is connected to the battery, that allows 402.3 liters of hydrogen production at 93.125 liters/kWh. The solar tracking system with high efficient energy storage system and hydrogen production systemar provides an effective solution for green energy development.
