The Solar Water Pumping Technology is an elegant option to use solar as the power source on virtually any well. The solar powered water pump system is capable of a wide range of applications, including irrigation systems, tank and cistern filling, and rural water supply for villages, cottages and homesteads. Thanks to a submersible solar pump and solar panels power generation, the pump produces water even on cloudy days or with minimal sunlight.
Submersible solar pumps are generally used for pumping from wells, and are designed to fit inside the well casing in a drilled hole. The most common casing size is 6", but 5" and 4" are also seen in older wells. Some older wells drilled for windmills are less than 4" (usually 2.25"), and solar submersible pumps will not fit. The well may be anywhere from a few feet to 1800 feet deep - but the deeper the well, the more expensive the system. Depths over 500 feet will generally cost quite a bit more. Solar powered well pumps are seldom suited for large amounts of water, such as irrigating larger fields. The largest pumps generally available are 1/4 to 3 HP.
With the Solar Water Pumping Technology there are no moving parts other than the highly reliable pump that is 200 - 500 feet underground, so it will be a much longer lasting solution compare to fuel power generator/pump water pumping systems.
