Why does the space under Escalon solar panels matter so much?
The three to six inches of clearance beneath a module gives birds shelter, warmth and protection from predators and weather alike.
That 3-to-6-inch clearance exists so air can circulate and keep modules from overheating, but it also happens to match the size of a comfortable nesting cavity for pigeons and smaller birds. Once one pair claims a spot, droppings and nesting material accumulate quickly, and the same cavity often gets reused across 2 or more breeding cycles.
Homes near Main Street, along Jones Road, or set back off Dent Avenue in the 95320 ZIP are not exempt just because they sit farther from open orchard land; pigeons range widely across the central valley grid and treat any unguarded array within San Joaquin County as fair territory.
Because the array itself is elevated and largely undisturbed compared to ground-level structures, it can go unnoticed by homeowners for 2 or 3 months while a colony grows through Escalon's hot, dry summers and tule fog winters, which is why symptoms like staining or a 10% output drop are often the first clue.

How the exclusion barrier is built
Mesh is measured to the array's exact outline and clamped to the aluminum module frame rather than fastened to the roof.
Exterior Prime professionals run a tape measure around the full perimeter of the array before cutting mesh, since an undersized piece leaves gaps at the corners that birds exploit within 2 to 3 days. The mesh itself is galvanized steel, chosen for its resistance to rust through Escalon's tule fog winters and the agricultural dust that drifts off nearby almond orchards during hulling season.
Clamps grip the module frame at regular intervals, distributing load without any screw passing through the panel glass, the racking rails or the roofing underneath. This keeps manufacturer warranties on both the solar system and the roof intact.
Where perching continues along a ridge or valley outside the array's footprint, stainless spikes can be added as a secondary measure, though the mesh itself handles the actual nesting risk underneath the modules.
C
Cleaning up before the barrier closes
Any droppings, feathers or nesting debris already inside the cavity are cleared and sanitized before the mesh seals the space.
Sealing an occupied nesting cavity without clearing it first would trap birds inside, which is never the intent of this work on any Escalon, 95320 property Exterior Prime serves in San Joaquin County. Reachable material is bagged at height within about 30 minutes and removed from the property rather than pushed toward a gutter or ground level.
The roof deck underneath is rinsed to lift acidic residue that droppings leave behind over time, since that residue can otherwise continue degrading roofing granules and metal flashing long after the birds are gone.
Cleanup pricing starts at $200 and scales with how much material has accumulated, which is typically higher on homes that have hosted a nesting pair through two or more breeding seasons without intervention.

What happens after the mesh goes on
Once the cavity is sealed, birds lose access to the nesting space and typically relocate within days.
Pigeons are creatures of habit, but without a viable cavity to return to, most move on to another perch within 1 or 2 days. Ridge or gutter perching may continue nearby, which is a separate, lower-stakes issue than actual nesting under the array.
The finished job is documented with before-and-after photos so homeowners have a record for insurance or resale purposes, and the treated area carries a five-year workmanship warranty on the clips and seams that hold the mesh in place.
Follow-up visits within the 5-year warranty period address any clip that lifts or seam that opens, at no additional charge, keeping the barrier effective through Escalon's full seasonal cycle for homes stretching from Main Street to McHenry Avenue.
