Is that an amorphous, mono or polycrystalline solar panel? How many watts is it rated at?


I guess you could say I got the pump from myself. smile There are lots of distributors and you should be able to get them for around $200-$220.

It is a Gast pump and the performance curve says 1-1.2 cfm's at 3 psi. It uses 75W-80W at full speed running. I don't worry about start up with the LCB

Panels- I am testing both Amorphos, and poly. For this application, I don't see any advantage. I am using a 135W panel and a 150W panel. I am finding out there is no need for this much "over power" to compensate for the cloudy days


Thanks for info. The wattage, cfms, and psi you're showing jives with what I'm seeing in the catalogs for other brands of 12 volt pumps. I think I'll stay way from the Chinese made ones though for sale on Ebay. 3 month warranty and no spare parts doesn't sound good to me.

If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.
