Multimeter verified that it was producing power. Panel weighs about 14 lbs. The frame was a little smaller than all the other panels I have. I purchased Renogy "Z" brackets, y adapter and extension cables separately. This is a well built panel. Looks nice on roof. ### ⭐⭐⭐ Review *by B***D on 14 March 2026* Ive ordered the 100 single setup twice, both came with everything i needed to install at work. Worked great. The new 2 pack 200w kit came with just the panels, NO mounting brackets. The ad doesn't specify or give any options for brackets. Pretty bummed i cannot complete my project this weekend and i need to find/order a set of brackets. FYI, on amazon.
