LH is designed for use in a wide range of locations. The most critical factor is sufficient water flow. Water flow is the amount of water that passes through the turbine at any instant, measured in liters per second(l/sec). The second important factor is head. The following table shows the minimum flow rate and head to achieve the quoted power output for each model:

It is important to keep in mind that output can only be accurately determined if head and flow measurements are made correctly, so care should be taken during this process. Two other important factors in a site assessment are system voltage, and transmission distance. The voltage and distance the power must travel can affect the efficiency and cost of your transmission lines.
