Solar Panel Cleaning in Conway, AR

A solar array is the only thing on your house that tells you when it needs cleaning — you
just have to look at the right number. If your production this month is meaningfully below the
same month last year and nothing else has changed, soiling is the usual explanation, and it is the
cheapest of all the possible causes to fix.

Conway has a specific version of this problem, and it is the same thing that fills the gutters:
loblolly pine.

Why Conway Arrays Soil Faster

Pine pollen. The spring drop coats everything, and on glass it forms an even
yellow film that reduces the light reaching the cells across the whole panel. It is also abrasive,
which matters for how it is removed.

Pine needles and debris. Needles lodge along the bottom edge of a panel where
the frame creates a lip. They trap moisture and dirt, and that lower band of the panel stays soiled
long after the rest has been rained clean.

Tree shade and sap. Anything overhanging drops resin, which bonds to glass and
attracts dust.

Bird droppings. These are the serious one and the reason spot-cleaning matters,
which is explained below.

Red clay dust in dry spells, which is what you get in a drought — less
rain means no natural rinsing at exactly the time there is most dust in the air.

Bird Droppings Are Not a Cosmetic Problem

This is the part most homeowners do not know and it is worth understanding.

A solar panel is a series circuit of cells. Light dust across the whole panel reduces output
proportionally — annoying but linear. A completely opaque spot, such as a
bird dropping, does something different: the shaded cell stops generating and instead resists the
current the other cells are still pushing through it. That resistance turns into heat, and a
localized hot spot can permanently damage the cell and, over time, the panel.

Most modern panels have bypass diodes that limit this, but they work at the level of a whole
cell string rather than a single cell, so the protection is partial. The practical takeaway: an
even film of dust can wait for the next cleaning. A solid dropping is worth dealing with sooner.

How Panels Should Be Cleaned

Purified water and nothing else. We use deionised water through a soft brush.
It leaves no mineral residue as it dries, which means no spotting and no squeegee needed. Ordinary
tap water is the opposite: Arkansas groundwater carries dissolved minerals that dry into exactly
the spotting you were trying to remove, and over repeated cycles those deposits bond into the
glass.

No detergents. Soap leaves a film that attracts soiling faster than before, and
some cleaners damage the anti-reflective coating on the panel surface — which is part of what
you paid for. Most manufacturers’ warranties have something to say about this.

Never on a hot panel. A Conway roof in July gets extremely hot, and cold water
on hot glass risks thermal shock. Cleaning happens early morning or on an overcast day, which is
also when the array is producing least, so you lose the smallest amount of generation.

Never walking on the panels. Standing on a module causes micro-cracks in the
cells that do not show as damage but do show as reduced output and eventually as failure. We work
from the roof surface around the array, or from ladders and extension equipment.

What Else We Look At

Being up there is a good opportunity to check the things that quietly cost you output:

• Debris under the array — in Conway, usually pine needles packed between
  panels and roof, which holds moisture against the shingle.
• Nesting. Birds and squirrels get into the gap under panels and chew wiring.
  Critter guard along the array edge is inexpensive and prevents a genuinely expensive
  problem.
• New shading. Trees grow. An array sized for the shading in 2018 may be
  partially shaded in 2026, and a branch trim is the cheapest output improvement available.
• Visible damage — cracked glass, delamination, discolored cells, or
  burn marks around a junction box, which we photograph and tell you to raise with your
  installer.

How Often

Twice a year suits most Conway arrays: once after the spring pine pollen has finished
— not during, or you will see the film return within two weeks — and once in
fall after the leaf and needle drop. Arrays under or near trees want more. Arrays on an open
roof with a decent tilt shed a lot naturally in rain and need less.

In a dry spell, cleaning matters more than usual, because the rain that normally does a partial
job for free is not falling.
