SW 340-350 XL MONO: 72 cells in series (6 × 12 matrix), Module efficiency 17.29% At that efficiency, I can't imagine what the size of the panel would be, but it certainly would be bigger than mine:
96 cells, 41.2x61.3 inches, 360w, efficiency 22.2%.
And, the cells were not Sunpower, either.
There may be Sunpower cells out there in frames and fabrications not from them directly, but YMMV as to experience with them
As to Sunbeam, their corporate page speaks only to flexible panels at a max of 100w. That may be useful to some, but not for me, unfortunately.
OTOH, if you have the real estate and the means of tying lots of them together, and, by inference, they somehow are cheaper than an actual Sunpower panel, absolutely, go for as much as you can support in real estate.
For us, our upgrade is literally life-changing. In no-wind conditions (last night was the first assist of any sort we got from our KISS), we STILL have yet to have to run our
Honda...
