Wind Generator and Solar Power Hybrid System at ERDI, Chiang Mai University

 

The Energy Research and Develupment Institute (ERDI) contacted ENGINO to design and install a hybrid system that would take advantage of both wind and solar energy. The solar power system converts solar energy into electric energy. The wind generators use the power of the wind to spin a generator in order to conduct electricity. This hybrid system has the ability to create electricity both day and night. The electricity from the solar panels and the wind generators is stored in batteries and then discharged through an inverter where the current is changed form DC to AC. After it is changed into AC current, the electricity can be used to power outdoor garden lighting. ERDI did not want to use the hybrid only to run outdoor lighting but also to be used as a teaching tool for the students at ERDI.

The wind generators are 200W, 500W, and 1,000W. The solar panel system is 480W.

 

The solar panel system is made of six 80W panels. The support beams were designed by ENGINEO.
