I have the exact pump that John shows above. They are on Ebay for about $80. I am running it on 2 12v 100w solar panels in series. I am pumping from a spring against approximately 65' of head. Very similar to your situation.
There are no batteries. The pump starts when full sun hits the panels. If it clouds up it slows way down. It pumps constantly from about 8:30 AM to about 4:00 PM as long as the sun is shining. It is delivering one gallon per minute.
I know this may seem marginal but it is nearly 500 gallons per day and would easily supply domestic use. It is doing wonders for our garden. It is affordable, it cost me about $300. It is free. It is solar. I don't see how anyone can complain about that.
I think the pump is capable of pumping 2 gallons per minute. More panels and a controller could get more water out of it. The pump is guaranteed for a year. If you ran it at high speed it might not last as long. There are a lot of pumps out there, this one is entry level I figure.
