PLEASE READ: Aligned 6 panels in series, flat on a trailer, sun @ 30 degrees off, recieved full 54.6v w/ 8 amps with 21.6v per panel's output maximizing the Makeskyblue MPPT voltage demand. That is 440w (after the 95% MPPT loss) of 600w, 75% panel output with ease (77% w/ MPPT loss). The panels were ready for more, load could have been heavier, panels voltage was optimal, and not an optimal charge angle. Six in series means the weaker panel sets the lowest amp reference, yet MPPT uses the combined voltage to maximizes low light output which is far overall superior! In Series these panels were amazing. Out of 1200w, I will get what I hoped for (12 panels).

Disappointingly low output of about 0.3 amps in full winter sunlight, new out of the box. It's just enough to trickle charge a small lead-acid battery. It's not anywhere near it's rated output and it consistently outputs no more amperage than my 15 year old 3x15 watt Harbor Freight poly-crystalline panels which are partially delaminated around the edges.

Beautiful design ! The red colored frog in the package was a nice touch! But I think he is poisoness
Verified purchase: Yes | Condition: New
bought this panel to add to solar on roof of RV. Fit eight in, operates as specified, may buy more.
Verified purchase: Yes | Condition: New
The new design is substantially smaller than the old one and produces the same output.
