The length of piping has little bearing on the energy required to pump, so water can be pushed over great distance at low cost. Small solar pumps may be installed without heavy equipment or special skills. The most effective way to minimize the cost of solar pumping is to minimize water demand through conservation. Drip irrigation, for example, may reduce consumption to less than half that of traditional methods. In homes, low water toilets can reduce total domestic use by half.
Water efficiency is a primary consideration in solar pumping economics.
When a generator or utility mains are present, we use a relatively large pump and turn it on only as needed. With solar pumping, we don't have this luxury. Photovoltaic panels are expensive, so we must size our systems carefully. Here is a guide to the data that you will need to determine feasibility, to design a system, or to request a quote from us.
