Imagine if you could rely on both solar and hydropower. Wouldn’t that greatly increase your chances of energy stability? The Electricity Generation Authority of Thailand has built one of the world’s largest floating hydro-solar farms in its Ubon Ratchathani province.

The hybrid project covers 300 acres (121 hectares) on the Sirindhorn Dam and is built on a reservoir. It consists of 144,417 solar panels that together form seven solar farms that can generate an impressive 45 MW of power.

The project also generates energy from dam turbines and uses a highly specialized energy management system that switches between solar power and hydropower depending on which one is more accessible at the time.

The hydro-solar farm can then ensure it performs at optimum levels regardless of weather conditions. Finally, to ensure that the water never gets contaminated, the solar farm section of the hybrid project is built from double-glass solar panels that are highly resistant to moisture.

What is the science, engineering, and technology behind the solar farm? What kind of turbines and solar panels does it use? Does the Electricity Generation Authority of Thailand have more plans for more such projects? We answer all these questions and more in our video.
