Make sure to clearly read your jurisdiction’s setback requirements. Mine does not comprehend solar on a fence, it only clearly defines rules for privacy fences, solar on existing permitted structures, and dedicated ground mount solar installations. Solar on a fence isn’t a configuration it considers so I expect if I would apply for a permit to build a solar fence that I would have to convince my AHJ that it’s a privacy fence in order to use fence setback allowances, which would be tricky and likely not be a quick process.
Talk to your AHJ before spending any money.
