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.


The control box with battery bank and charge controllers.


The breakers, meter, and digital charge control display. The green light shines when the batteries are discharging into the lighting system. The red light shines when electricity from the grid is being used to run the light system.

The system can run ten outdoor lights.

ENGINEO would like to thank ERDI for the oppertunity to work with them.

Anyone who would like to know more is welcome to visit the sight, contact ERDI or ENGINEO.
