More Solar for "Us"
Ok, I went off.the deep end? Bought 3 used 37watt uni-solar panels and a blue sky 2000e controller for the hefty price of $400, They were being listed as 75w panels, they are not The tested open...

From 10.72 or more down to 8.39 in two weeks ,same panels same wiring , saturday was clear and warm
Monday new wire & blue sky controller reading went up from 8.39 to 9.2 , that was the increase with the new setup
I know output drops with the angle of the sun, just disappointed to lose 2+ amps in two weeks
Rained last week and Monday I cleaned the panels while on the roof to make the new connections to the 8ga
Got a reading from the control at 9am 3.7 in & 3.7 out
Clamp on reading 3.9 in & 4.0 out
Will mount the shuntless in the output circuit before noon and take triple output readings at 12:30, but only two readings for input
Can't move the shuntless back & fourth
My paper work also says 30v input, these panels have a working voltage of 17.5v so stacking them in series is not going to happen, I will just have to watch for some.more compatible panels to enlarge my system
