Hurricane design, wind load, and product approval
Miami-Dade and Broward form Florida’s High-Velocity Hurricane Zone (HVHZ), where roof-mounted solar must account for severe wind forces. Wind load is the push and uplift a system must resist, not a promise that panels are hurricane-proof. Ask for a quote that includes site-specific structural design and the applicable Florida Building Code requirements. The County’s solar permit guidelines call for roof details, wind uplift information, and attachment details. A Miami-Dade Notice of Acceptance (NOA) records approval conditions for a product or assembly. Ask the designer which NOA, Florida product approval, or other accepted documentation applies to the proposed equipment and mounting method. The approval must fit the roof and installation, not just the brand name. Use the County product-control search to check the cited approval and have the permitting office confirm what it accepts.
Flat, tile, and shingle roofs
A flat roof, tile roof, and shingle roof need different attachment and waterproofing details. On a flat roof, ask how the layout preserves drainage and service access, and how the design addresses uplift and any added weight. Do not assume loose ballast is acceptable for your building. On a tile roof, ask how mounts reach the structure below the tiles, how broken tiles are replaced, and how each penetration is sealed. With shingles, ask about flashing, roof condition, and the roof warranty. These are design questions for the installer and roofer, not a one-size-fits-all mounting recipe. Review the County’s roofing and solar permit resources. If reroofing may be needed, compare doing it first with paying to remove and reinstall panels later. Put responsibility for roof leaks, removal, and reinstallation in writing.
Condo, co-op, and HOA roof rights
A condo owner usually cannot authorize solar on a shared roof alone. Check the declaration: the roof may be a common element, with the association responsible for its upkeep. In a housing co-op, the ownership structure also differs from owning a single-family lot; start with the board and governing documents. Fla. Stat. §163.04 limits restrictions that effectively prohibit solar and permits certain location controls that do not impair operation. It does not turn a shared roof into one unit owner’s property. A single-family HOA review and a condominium association’s control of common property are different questions. Florida’s condominium statute also addresses association solar installations. Explore a board-led system for common-area loads, with costs, roof rights, maintenance, and metering reviewed together. Ask the association’s counsel how the law and documents apply before signing.
Battery storage and backup limits
A battery can store solar energy for later use, but backup power depends on the complete system design. Ordinary grid-connected solar does not by itself keep a home powered during an outage. The inverter, controls, and battery must be designed to isolate safely from the grid and serve the chosen circuits. The Department of Energy’s solar resilience guide explains that role. Start with the loads you need, such as refrigeration, lights, or medical equipment, rather than a promise of whole-home backup. Ask about usable capacity, power output, expected runtime under those loads, and how the battery recharges during bad weather. Include installation, warranty, replacement, and safe siting in the quote. Storage adds cost and does not guarantee uninterrupted power through every storm or a particular bill saving.
Renters and shared solar subscriptions
Renters generally need the property owner’s permission for a rooftop installation; a tenant’s electricity account is not ownership of the roof. Ask the landlord whether a building-wide project is planned and how costs and benefits would reach tenants. If rooftop access is unavailable, FPL SolarTogether is a separate utility subscription model: subscribers pay a charge and receive credits from shared solar generation, with no panels installed on their roof. That is not a free rooftop system or a battery backup service. It may be worth comparing for an FPL customer who rents or lives in a condo, but availability and eligibility change and must be confirmed directly with FPL. Review charges, credits, cancellation, and moving terms. Customers of a municipal utility should ask their own provider what options, if any, it offers.
County permits versus City of Miami permits
A Miami mailing address does not tell you which office issues the building permit. Check whether the property is in unincorporated Miami-Dade, the City of Miami, or another municipality before the installer files. The Miami-Dade solar photovoltaic permit page explains the County process, while the City of Miami solar permit guide describes the City’s route. Ask the local office to confirm jurisdiction and any County reviews that still apply. A proposal should identify who prepares structural and electrical plans, files them, answers review comments, and schedules inspections. Roof work may need its own approvals. Building approval and utility permission to operate are separate steps; one does not replace the other. Use FPL’s process only for FPL addresses, and the relevant municipal utility in Homestead or Lake Worth Beach. Confirm requirements before work begins.
