Why isn solar pumping more popular?
It’s a new technology, with challenges of its own. The nature of variable electricity in the form of direct current (DC) is quite different from conventional, steady alternating (AC) current. Using it economically dictates utilizing the long solar day, drawing a minimum of power. This means pumping slower than conventional pumps. Pumping at rates of less than 6 GPM requires different mechanisms from the conventional (centrifugal), unless we have power (money) to burn. Small solar pumps are unique, both electrically, and mechanically. The environment of a water well is unforgiving. Any imperfection will cause a failure. Since photovoltaics (PV) hit the market in 1980, we have seen many successes and many failures in solar pumping. Solar pumps have been difficult to market, too. Until recently, there existed a great gap in the range of available products. Lorentz solar pumps have been around for many years and are a trusted name around the mill, currently we back and warrant any Lorentz
