The City of Madison's solar page lists several. You need a building permit, which requires drawings and calculations showing the system is safe plus a site plan and placement plan. You also need an electrical permit, which requires a cut sheet showing the photovoltaic equipment is UL listed. A solar hot water system needs a plumbing permit, and some systems need a heating permit. Zoning approvals depend on your property. Planned development, historic district, urban design and conditional use properties need extra approvals, which can add days. Fees apply, and staff can quote the total when you apply. After you get the permits, post them at the site and schedule inspections, including a final inspection. This covers the City of Madison only; other communities set their own rules.
