Medium size solar pump stations

Does anyone have experience with medium to large scale commercial solar

pump stations?







I'm looking for a dual pump solar pump station with heat exchange

for a project with roughly 1000 sf of flat plate collectors (design flow

rate ~ 17GPM). Does anyone know of a good pump station in this scale.

We've always built our own, but I am interested to see what is available commercially.





I'm familiar with Purist Energy, Enerworks and PAW. Any others?







The PAW Solex HF would be great, but I think it is about half as big

as we need. Does anyone have any experience with ganging a couple pump

stations together in parallel? What are the issues associated with that?







I look forward to hearing your experience.







thanks

    Solar pump stations

    run up to about 10 GPM with a Wilo Star 30 pump. The only other one I've seen is that large Heliodyne skid mount package with HX and multiple Grundfos Magna's.



    Generally those large arrays can be broken up into several small array groups and use two pump stations, it may be less money than the large Heliodyne station.



    Or custom size and build a pump station to your exact spec.
