Panel's output is around 75% in perfect conditions
800 watt array =4 200 watt panels wired in series,the best I got was 600 watts in absolutely full sun and clear skies. Iโm a little disappointed I thought I would get at least 700 plus

Perform Well
Amazing how little light is required to produce power. Frames are a bit flimsy. Keep the span short for support.

low output
Panels seem to be holding up fine but the output is way less than expected. On a good day I'm seeing 180 watts at best from these 2 panels.

Under a year and toasting themselves!
I threw 6 of the 100w versions on my shed for a mini off grid setup. Also use them for a portable setup for desert trips. I have to say they are compact and put out great power. Maxed out the Victron 150V/35A MPPT. Solid setup. Great value! Updated: I have had 12 of these for under a year and have had 5 lf them get hotspots and melt. Not good at all. Offer me 1/2 off on replacing. Hahahaha. Note all are wired under 150v total, way under specified rating.
