If you want to pump using a solar water pump system, then we need to find out the well specifications. Once we know the depth, static level and the amount of water you need, I can give you an idea of costs. Solar is a great way to pump, but remember that solar panels can "walk off". Make sure that your system is in an area where it can't be vandalized. Solar pumping is great because you can move the system from one well to the next, depending on where you need the water.
An example of a typical system:
Sureflo 9300 pump
Tracker for the panels
2-75 watt modules
Extra diaphragm
100' of 3/4" poly pipe
100' of 1/4" rope
100' of 10/2 submersible wire
All adapters
Shipped price of $2700
Keep me posted if I can help you size a Solar Pumping system!
