Im more interested in the panels in the second ad--a matching set of 4, 300w Trina panels.
They have never been installed and are 36V panels.
I will be using a Morningstar Tristar 60A MPPT charge controller into a 24V battery bank, so I'm not worried about any of that stuff.
From what I've read, the efficiency of mono vs poly seems almost negligible.
What I'm trying to figure out is if these Trina panels are quality enough and if the lack of warranty is worth the 60% savings in upfront cost (1600 vs 900).
The panels I was originally considering are these:
SolarWorld SW 315 Pro XL
15W more and they are Mono, which, I'm not sure how much I am worried about.
I am set on 4 panels, and their dimensions cannot exceed 40"x80"
I want 1200W of rated panel power.
