Review: 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. I’m a little disappointed I thought I would get at least 700 plus

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

### ⭐⭐⭐ low output
*by N***A on September 18, 2025*

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.
