Pondering another solar install!
In my previous home I had a trouble-free SolarEdge system and enjoyed near zero electrical bills most of the year. This helped sell the home! I've now moved South to Florida and would like to go solar again only this time with battery backup. I have an outbuilding with a large roof that's South facing and already wired that I suspect would be a good location as it sees little shade. Be a real shame if something happened to that one damn pine...
My previous system was on a standing seam metal roof - no exposed fasteners. Rails clamped down to the ribs but I had some fairly ugly conduit to look at - zero penetrations. The building I'm considering now has an asphalt shingle roof in good shape, the main house has shingles too but in less great shape. The outbuilding roof would probably be straightforward to replace with tin and I'm wondering if this might be a good idea. I'm new to the state but close enough to the coast to know that hurricane winds are for sure a possibility.
Is replacing the roof with metal a good idea as I'm considering a new system? I like the idea of not sweating shingles or roof penetrations but I'm not sure about uplift on clamps holding down panels. When my last install was done the county had never inspected solar on a tin roof and tried to tell me it had to be drilled down and manufacturer engineers had to get involved to satisfy them. Is this a bigger concern in Florida? Impact damage is another thought - should I consider buying a few spare panels when I'm getting quoted?
Paying a couple hundred bux a month for power after years of no electrical bill is a shock and knowing I'll be here for years this project is high on my list! Having battery backup for storms would be really nice, power on sunny days has even been iffy - don't get me started on Spectrum lol. I'm East Coast South of Cocoa FWIW and if the roof this is probably going on wasn't as high as it is I'd consider a DIY install I swear. Any other Florida weirdness I need to know about?
Thanks!
