how deep can a solar well pump be used
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 if you have AC power available.
