Every mounting component needs approval here
The Florida Building Code defines the High Velocity Hurricane Zone as Miami-Dade and Broward counties. It is the strictest wind-resistance framework in the state and it exists because of what happened in 1992.
Mounting components used in that zone are expected to carry a Miami-Dade Notice of Acceptance or a statewide Florida Product Approval with High Velocity Hurricane Zone certification. A Florida Product Approval with HVHZ certification is accepted statewide, including in Miami-Dade and Broward.
So ask any installer a direct question: which specific racking, clamps, flashing and fasteners are you proposing, and does each carry a current Notice of Acceptance or Florida Product Approval with HVHZ certification. Ask for the approval numbers, not an assurance.
Ask the building department what your specific installation requires, including whether site-specific wind load calculations and a Florida professional engineer's stamp are needed. Confirm that before an installation date is agreed rather than during plan review.
Why two Miami quotes can differ so much
Two quotes for the same roof can differ substantially purely because one has priced HVHZ-compliant hardware and engineering and the other has assumed standard components. The cheaper one is not cheaper, it is incomplete, and the difference surfaces after you have committed.
Ask each installer to itemise the engineering and the approved mounting hardware separately rather than folding everything into a single figure. Then compare the remaining lines against each other so you are comparing like with like.
Ask how many projects they have permitted in Miami-Dade and what the review process involved. An installer who works here routinely will discuss Notices of Acceptance without prompting, because every job they do needs them.
Ask what happens if plan review requires additional attachment points or different hardware than assumed. Establish in the contract whether that is priced in or billed as an extra, because in this zone it is a foreseeable outcome rather than an unlucky one.
How your exported solar is credited
Florida investor-owned utilities offer full retail net metering under Rule 25-6.065: excess solar is credited at the retail rate and rolled forward monthly, with an annual true-up at the utility's lower avoided-cost rate. Systems are generally sized to no more than 115 percent of annual usage.
Note the true-up. Monthly rollover at the retail rate is favourable, but a surplus that survives to the end of the year is settled at the avoided-cost rate, which is considerably lower. A system deliberately oversized to bank credit is giving value away at the annual reconciliation.
That, together with the 115 percent sizing guidance, means the sensible design is matched to your consumption rather than to your roof. Ask your installer what percentage of your annual usage the proposed system covers and how the true-up was handled in the projection.
Confirm which utility serves your address first, because municipal electric utilities in Florida set their own net metering policies and credit rates and are not bound by the substantive parts of Rule 25-6.065.
Your association cannot say no, and what the federal change means
Florida Statute 163.04 provides that a deed restriction, covenant, declaration or similar binding agreement may not prohibit or have the effect of prohibiting solar collectors or other renewable energy devices from being installed. A property owner may not be denied permission to install them by any entity granted the power to approve, forbid, control or direct alteration of property.
An association does retain one specific power. It may determine where on the roof solar collectors may be installed, within an orientation to the south or within 45 degrees east or west of due south, and only if that determination does not impair the effective operation of the collectors. So a proposed relocation that costs you meaningful production is worth challenging with a production model rather than an argument.
Follow the normal application process even so. Submitting layout, mounting method, panel and frame colour and conduit routing removes most of the uncertainty a committee is actually reacting to, and an application that arrives complete is approved far more often than one that arrives as a dispute.
On the federal side, the 30 percent Residential Clean Energy Credit under Section 25D expired for property placed in service after December 31, 2025, so a cash or loan purchase now receives no federal credit. Section 48E survives at 30 percent for third-party owners under leases and power purchase agreements, so ask any such provider what they claim and what of that value reaches you, and confirm with a tax advisor.
