National brands vs. local installers: what to expect
Large companies such as Sunrun, Sunnova, and Blue Raven Solar advertise heavily and can offer standardized processes and nationwide support. Local installers tend to be smaller, know local permitting and permitting officials, and may react faster after a storm. Neither option is universally better. National firms can offer scale and sometimes financing channels, while local crews may be more familiar with Miami-Dade code, roof types common in Miami, and hurricane-related installation details. Ask any installer about their experience with local permits, Miami-Dade approval processes, and recent work in your neighborhood. That will tell you whether they can handle the specific challenges of your roof and storm exposure.
What to compare on every quote
Make quotes apples-to-apples before picking a winner. Compare: system size in kilowatts, expected annual production for your address, panel and inverter brands, mounting and flashing details for your roof type, and estimated timeline. Look at permit and inspection handling, who will coordinate with the utility for interconnection, and what the installer’s workmanship warranty covers. Normalize price comparisons (for example, cost per watt) but remember that price alone doesn't show long-term service or quality. Also check installer credentials, local references, and how assumptions like shading, panel orientation, and tilt affect production numbers. Finally, remember that final price and performance depend on your location, roof condition, electricity use, financing, and installer quality.
Hurricane and durability considerations
Wind resistance matters in Miami. Panels and racking are rated for different wind speeds, and correct attachment and flashing are critical for roofs that see hurricanes. Ask installers whether they design systems for high-wind zones, whether their equipment meets local code or Miami-Dade testing where required, and how they handle roof penetrations. Also check how they respond after storms: can they make temporary repairs quickly, and do they work with your insurer for damage claims? Before installing, confirm your roof is in good condition; replacing a roof after panels are installed is more costly and disruptive.
How to get quotes and vet installers
Request at least three quotes and include both national names and local companies so you see the range of approaches. Provide the same information to each company: address, recent electric bills, and current roof photos. Ask each installer for local references and examples of recent Miami installations. Verify licensing and insurance, and ask how they handle permitting and inspections. When reviewing proposals, check that production estimates use the same assumptions about shading and panel placement. Finally, be wary of high-pressure tactics and get everything in writing before signing.
