Change of Policy for Design of Pump Systems
In the past, our pump tech designed systems for anyone who called. Because customers were easily able to price shop the parts from companies who do not provide design services, we could not compete with the quantity pricing.
Now, we only design systems for customers who are buying, or who have bought, off-grid solar electric systems. Pump system design is time consuming and requires effective communication with the manufacturer. We are sorry we are not able to provide this for everybody at this point.
Answer Three Basic Questions
Before we are able to assist you, you will need to answer these Three Basic Questions about pump sizing. (You may first want to read some pump facts, or some information on submersible and surface pumps.)
1. What flow rate is required?
2. What is the total lift water has to travel (vertical distance)?
3. What is the water source?
Other helpful information:
Where is the pump going to be located (city, state)?
Do you want to have an AC Power Source?
What is the recovery rate of the water source?
Do you want a float switch if pumping into a storage tank?
How do you want to mount the solar panels? (Pole mounts are generally used.)
What type of application will you be using your pump for, i.e. water system for home, irrigation, livestock, pond or other?
Our Personal Experience with Pumps
When local well drillers in northern New Mexico told us it was impossible to pump water from a 1,000 foot well with a solar electric system, we kept looking. We found Dankoff Solar, at that time, the most knowledgeable source for information and solar well pumps, and we placed a pump that has worked reliably for 12 years.
We now sell pumps for all kinds of systems, from deep wells, to water catchment systems, to cattle tanks. Call Wholesale Solar and give us the details on your well—how deep it is, how far the water has to be pumped from the well, what the drop is, what the water source is—and we'll figure out the rest.
