What Miami homeowners should check

Miami solar designs must account for hurricane wind loads, salt air, intense rain, and frequent roof work. Wind-rated mounting, corrosion-resistant hardware, drainage clearance, and the remaining life of tile or shingle roofing are central quote-review items.

FPL is the dominant utility, and interconnection follows Florida requirements. Homeowners should confirm insurance documentation and any local building-review requirements early because those steps can affect the project schedule.

At the state level, Florida currently uses full retail net metering. A typical interconnection takes 3–8 weeks, but utility review and local permitting can extend that range. Check current rules before relying on a proposal's export-credit or installation-date assumptions.

What should I verify before signing a solar contract in Miami?

Confirm that the quote names your actual utility, uses a recent electricity rate, includes measured shade and roof-condition findings, and explains who handles permits and interconnection. Ask the installer to separate guaranteed equipment and workmanship terms from estimated production, incentives, and savings.

Illustrative 5.6 peak sun hours, 14.08% production losses, 12.0 cents/kWh and $2.8/W. The retail-value ceiling assumes every kWh earns retail value; lower export credits reduce it. The cost/value ratio is not a full payback model and excludes repairs, financing and rate changes. No new Section 25D homeowner credit in 2026.
