Review on CMYYANGLIN Solar Panel Mounting Brackets ABS Corner Bracket Kit 7PCS for RVs, Caravans, Vehicles, Camper Vans, Sheds, Garages, Boats – Drill-Free Installation, White by Gary Cole

These are beautiful and powerful panel mount brackets. Leave enough space at the bottom for things that are easy to clean and dissipate heat. Looks good (mine is white to match my van's roof, but I also came in black). Easy assembly of the panels and easy access to the screws later when maintenance is required. Not sure how well they will stick to the roof over time, but for now they are glued well (time will tell if I need to use mounting screws). Metal Z-bars require screws and sealant and regular inspections (differential extensions). They appear to have enough surface area for successful bonding and do not require holes penetrating the roof. Again, time will tell.
