Water Pumping with Solar Panels

Solar water pumps provide an effective cheap and dependable method for providing water in situations where water resources are located over long distances, fuel costs, or power-lines are unreliable. Designed specifically for DC power and requiring no conversion, they are great in low sunlight conditions.
The biggest advantage that draws more and more residential customers to solar water pumps is that they generally are able to move small amounts of water over a longer duration of time. This differs from conventionally powered AC pumps which require huge volumes of power to move large amounts of water in a short duration.  Since the solar output doesn’t spike, but rather remains consistent throughout the day, solar pumps provide a steady output of water.
Installing a solar powered pumps is a great alternative to windmills, gas/diesel pumps or even ramp pumps which are all quite costly to install. Solar pumps are stand alone systems that work effectively and avoid the cost associated with more expensive pumps.
A couple of reasons why residents of Ontario might want to consider Solar Pumps are:
  • Cheaper than other pump options.
  • Easy to install.
  • Easy to fix.
  • Environmentally friendly
  • Stand-alone systems that don’t require additional power.

These are typically 220-volt alternative current models. One of the biggest problems our clients at Solar Panel Ontario have found is that such high-voltage systems can put a huge strain on your inverter when you start it up. Users have experienced a slight to massive power surge in the home when starting these systems.  You might experience the lights dimming or worse yet, a full-out inverter failure.

 

 

 

 

Two kinds of solar water pumps, submersible and surface pumps:

One of the easiest options is to use a smaller model. A 120-volt AC model works well and is much more efficient and doesn’t put the same amount of strain on your inverter.
One area of caution is when setting up your outdoor solar panel system for your well pump please be sure to use a proper mounting rack.  The rack should give enough clearance between the ground and the solar panel.  This is important to avoid damage from falling debris, pets, floodwater or other animals.
As discussed in the inverter section, if you are unsure about the amount of wattage required to run your solar pump just check on the rating located on the backside of the device.  Your well drilling company should also be able to determine what wattage rating you’ll need from your solar panel.

Surface pumps are great for smaller areas of water: ponds, streams or wells. Although they won’t get the vertical lift that submersible pumps can get they are still an effective way to generate power in rural ares in Ontario.
