Constant salt exposure accelerates connector corrosion faster here than anywhere else on our route. A drone thermography sweep with handheld infrared confirmation catches a failing connector or cell before it takes down a whole string.
Direct Gulf salt spray
Homes on the Gulf side of the island, especially around Bean Point and along Gulf Drive, take a near-daily salt mist that forms a hard film within weeks of a clean if left alone.
Bay-side salt and marine growth
Sarasota Bay-facing homes near the north end see slightly less direct spray but more biological growth thanks to calmer water and higher humidity along the shoreline.
Salt-air metal roof staining
The island's many metal roofs show streaking around fasteners and panel seams faster than shingle does, and that staining can bleed onto lower-mounted arrays if not addressed.
Mostly older Old Florida-style elevated homes on stilts with metal roofs in Anna Maria and Bean Point, alongside a denser mix of shingle and low-slope roofs on Holmes Beach and Bradenton Beach rentals and cottages. Elevated stilt homes change our approach — poles often need to reach both up and around a wraparound deck rather than straight off the ground.
We fly a radiometric thermal camera over the full array under load, then follow up with handheld imaging on anything ambiguous or shaded. Radiometric means every pixel carries an actual temperature value, not just a false-colour gradient, so we can measure the delta between a suspect cell and its healthy neighbours instead of guessing from a pretty picture.
Single-cell hot spots from micro-cracks or manufacturing defects. Whole-substring heating that points to a failed bypass diode. Warm junction boxes and connectors that signal a resistive joint on its way to an arc fault. Reverse-biased shaded cells that soiling or a new tree branch has pushed into dissipating power instead of producing it.
Anna Maria Island sits outside Hillsborough County, so a $50–$100 travel fee applies depending on routing. Booking alongside a neighbour usually removes it.
