How do I choose a Solar Pump and the Solar Panels to power it?
Selecting the Solar Water Pump
Solar water pumps can be used with ponds, streams, or wells (generally 10-15 cm well casings). If the water level is lower than 6 meter and the solar pump will need to lift more than that, a submersible solar pump will work great and can lift vertical distances of up to 213 meter. Surface solar pumps can use suction to draw water vertically about 3-6 meter. However, once they have lifted that relatively small amount, surface solar pumps can then push water great distances, like 60 meter or more! The Solar Pump System on Promotion can produce 1600 litres per sun hour at max. 45 meter head.
Selecting the Solar Panels
The solar panels powering the solar water pump are sold separately. We provide technical support showing you how many watts of solar panels are needed to produce the desired water flow.
The size of the solar pump and the amount of solar panels needed both depend on how many liters per day or liters per minute you want to pump and the vertical head the pump needs to overcome. Call us to get friendly, technical advice to help you design your Solar Water Pumping System.
Should I use Batteries with my Solar Water Pumping System?
Most solar water pumps run directly off solar panels (PV direct) and do not require batteries. Using batteries may complicate an otherwise straight forward application. Instead of storing electricity in batteries to run the solar pump at non-sunny times, most people prefer to store the water in a holding tank. This results in the same effect, water when you need it, with less cost and less complexity |
