I recently purchased two Sunpower SPR-E20-327 panels from a contractor that had some extras. The VMP is 54.7, Imp 5.98, Voc 64.9, Is 6.46, A=15. I would like to set up a system using these panels to drive 5 small pumps at 1300 watts per day, with the capability to expand to 10 pumps. Trying to put together the best set of components to go with the panels, or should I start from scratch, just looking for a reliable system

Thanks,
Ken
 
What pump do you intend on running?
How are you going to operate them? Continuous, daytime? Etc.

Mount the array sturdy, dont skimp on height or beef in the materials.
Use the MC brand connectors and you should be good. There usually arent too many parts unless you need continuous operation.
