I'm looking for a budget-friendly way to securely mount 19 solar panels on the trapezoidal tin roof of a remote fishing club. Building codes aren't a concern since the location isn't heavily used. I've been thinking about using Unistrut as mounting rails paired with L-brackets to attach them directly to the roof. However, I need to figure out how to install the brackets securely without risking leaks or damaging the metal. Has anyone successfully mounted panels on a similar roof? What fastening methods or clamps would you recommend? I'm open to any tips, material suggestions, or experiences you might have had with similar setups. Thanks!

You should definitely check out S-5 clamps. They’re great because they don’t penetrate the roof, so you won’t have to worry about leaks. Just make sure to find the right clamp for your type of roof.
Also, be sure to clarify if your roof is actual tin or if it's a magnetic steel type. If it’s the latter, you might be able to use magnetic mounts, which could simplify the process. Just keep in mind that with a large installation like yours, that could get tricky.
If you're on a tight budget, consider using Unistrut but ensuring you seal the brackets properly. Plenty of DIY folks have made it work without issues. Just remember to keep the fasteners rust-resistant!
Thanks! I’m aware of S-5 but was hoping for something a bit cheaper since this is a not-for-profit club and we only use it a few times a year.
