Review on ⚡️ Solar Panel Mounting Brackets - Houseables Roof Panels Z Bracket, 2.5” x 1.5” x 3.9”, 4 Sets (16 Pc), Aluminum, Off Grid, Adjustable Mount Nuts & Bolts - Ideal for Solar Power, Boats, Wind Generators, RVs, Trailers by Eric Nelson

These brackets are very easy to install, they are strong, durable and very well constructed. I actually mounted very strong neodymium magnets on brackets and attached my small 100 watt panels to my steel roof without drilling any holes. Four brackets per panel and magnets hold each panel securely without worrying about them flying off in high winds. A few minutes later I installed the panels with brackets. They are the perfect size for my metal roof and clear the ridges between each roof panel. I highly recommend these braces and give them 5 stars.
