Dear Nando, Â Yes. The water source is stable all over the year. There is much water in Summer. Can Kaplan turbine and Banki turbine used for microhydrolic...
Antonio: With your water volume you can have a KAPLAN or a Banki, but the banki will be much larger and heavier due to the water volume and the low head may...
