Solar Powered DC Water Pump

Wow, assuming you can get 7 hours of sun light a day from solar you would need a bunch!  10,000 gallons a day would work out to about 24 gallons per min. X 60 Min's X 7 hours, a monumental task for a solar array.  I would consider a undershot water wheel driven by the river current hooked to a pump. You could use a stationary wheel or a floating platform (boat - with 2 paddle wheels)and a belt or gear drive pump. Since the water wheel will run 24/7 you would only need a pump that delivers about 7 gal. per min.  I have a rough sketch of a similar arrangement for electrical generation if you visit alternativeenergy.com and look up my profile, we can get in touch and email each other.  Look under Jim c. Look for the solar powered canoe in pictures to find me.

Dear Terry, I suggest you use 2 x Grundfos SQF2.5 pumps. Each pump will deliver about 22000 liters per day(4900 gall per day). Power each pump with a 1kw array of PV. Alternatively use the Grundfos 5A6 pump with a 1.6Kw array PV. The delivery will be about 7000 gall per day. We have used the Grundfos range of RE pumps extensively in our country and they are marvelous. They can be powered with a DC supply like PV or Wind or combination,from 30V to 300VDC or 90V to 240V AC from a generator or mains supply without any problems.
Feel free to email if you need more info or a quotation to deliver to Nigeria.
