Solar Water Pumping systems

Solar water pumping systems have many advantages over windmill water pumpers. Though the initial cost of solar powered systems can be similar to that of windmills (however, in many cases far less!), the lifetime costs are much lower. Windmills must be used where there is a steady, constant wind for maximum results while solar powered pumps operate anywhere the sun shines. Solar pumping systems can be installed in less than a day by an individual or small crew and can be portable, while windmills (because of the need to erect a tower) can take a larger crew a much longer time to install. Windmills are secured to the ground and are stationary. Solar powered water pumping systems are the modern day, upgraded version of the wind.

How to gathering data for Solar water Pumping

To choose the right pump, we need to know:
- Daily quantity of water required (m3/day)
- Is there a minimum requirement for water flow (m3/h)?
- Vertical lift of water: depth of water in the well + elevation of the tank
- Depth of the well
- Is the water available all the time?
- Volume of the tank (m3)
- Distance Well to tank
- Diameter of the well
All the pumps can work with solar or batteries. It just doesn't make sense to use batteries if you have a tank. It is better to oversize the solar installation to make sure that the customer has water everytime in the year.
