Common Solar Panel Problems Mesa Homeowners Should Watch For

Solar panels are common across Mesa, but Arizona dust, heat, birds, and hard water can create a few problems homeowners should watch for.

Dust and Dirt Buildup

Mesa's dry climate makes dust buildup common.

Rain may rinse away some loose dirt, but it does not always leave panels clean. Over time, dirt, pollen, and other debris can remain on the glass.

If the panels are visibly dirty, professional solar panel cleaning in Mesa can remove buildup using purified water and a nonabrasive brush.

Pigeons Nesting Under Solar Panels

The space underneath solar panels gives pigeons shade and protection, making it a common nesting area.

Signs can include:

• Pigeons repeatedly entering under the panels

• Droppings around the roof or driveway

• Feathers

• Nesting debris

• Birds returning to the same section of the roof

If pigeons are already established, pigeon control in Mesa may require physically blocking access to the nesting area rather than simply cleaning it.

Loose or Damaged Bird Mesh

Homes that already have solar panel bird mesh should occasionally check it from the ground.

Loose sections or openings can allow pigeons back underneath the array.

Proper solar panel bird mesh should fit closely around the accessible perimeter of the panels.

Bird Droppings on the Panels

Pigeons and other birds may leave droppings directly on the solar panels.

Droppings can be harder to remove than ordinary dust, especially after they have dried in the Arizona sun.

Repeated droppings can also be a sign that birds are regularly roosting or nesting nearby.

Hard Water Spots

Sprinklers that spray onto solar panels can leave mineral deposits behind after the water evaporates.

Mesa has hard water, so repeated sprinkler exposure can create noticeable spotting over time.

Adjusting sprinklers so they do not hit the panels can help prevent additional buildup.

Debris Under the Solar Array

Leaves, nesting material, feathers, and other debris can collect underneath solar panels.

Because homeowners usually cannot see beneath the array from the ground, the problem may go unnoticed until birds or debris start appearing around the roofline.

Watch for Changes

You do not need to constantly inspect your solar system. Just watch for obvious changes such as increasing dirt, pigeons going underneath the panels, loose mesh, or repeated droppings.
