I found a great deal on some solar panels on Amazon. They are sold by a company called DMSolar. The DM145 panels (145 watts) were sold for $160. If you have Amazon prime, you get killer two day shipping. Such a steal…if the panels are legitimate. Deals like this are often too good to be true. Upon receipt and inspection, the panels look clean and of good build quality. They are marked as being manufactured in Thailand…I wish I knew who really made them.
I hooked three panels up in series to run my SQFlex pump (ideally at 60VDC). The pump runs! At this point I do not have more than anecdotal evidence on the performance. I would guess I’m getting three to four gallons per minute. The watt meter on the pump’s control unit indicated 230 watts (out of a theoretical maximum of 435 watts)
