Review on 🔆 MMJKU Solar Panel Z Brackets for RV, Boat, and Off-Grid Installation - Set of 4 Units, Black by William Mahajan

These appear to be large black aluminum mounts but are no heavier than other mounts to support a 300w panel. Other similar (exactly the same?) specs with a max output of 150-200 watts. But the orientation of the panel mount slot does not match the holes in the panel frame and does not grip the panel properly without sawing the slot to a longer length - for Qcell panels. which are commonly used by Tesla and are very popular. An additional washer is also required, which is not included for the smaller screw head. Nut diameter is large enough. Groove dimensions are not shown so there is only one way to find out! Luckily, Revane made this easy and quick to do.
