What head and flow measurements are required for my site to be suitable?
All watercourses have the potential to produce energy, though in order for a hydro system to be viable there are limits. The precise head and flow measurements needed to make a hydroelectricity generation viable depend on the intended purpose of the installation. A very general rule of thumb is that the minimum head measurement be 2 meters at the very least and the flow at least 2 liters per second.
One should always speak to prospective installation companies about this before making any final decisions, however, as these measurements are of utmost importance to the viability of hydro systems.
