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...

Yes, lower cost of PWM is TAD offset by the number=cost of panels and a bit more wiring pains. What annoys me is that PWM are not as "automated" as MPPT.
Solar PWM vs MPPT Cost comparison 1-23-17
PWM
Cynergy 160W $115, 5 panels 800W $575
TriStar TS-60 $183
Installation cost over MPPT $100
Total $858
MPPT
Amerisolar 250W $163, 3 panels 750W $489
TriStar MPPT 60 $483
Total $972
Wow my 750W system cost $1400 without the remote display in 2014!
Based on this I'd make the same decision favoring MPPT today.

There are of course many other factors to consider. It seems clear to me from numerous posts that many start with a smaller solar system and PWM is much more cost effective for smaller sizes. And then with upgrades to more solar there is just no practical starting over.
