Most solar arrays go years without anyone looking at them closely. They sit on the roof, the app says they are working, and nobody climbs up to check. That is mostly fine, because panels are tough.

But hail, birds, wind, heat and time all leave marks, and some of those marks matter. A visual inspection is how you find them while they are small. This article walks through what we look at, panel by panel, and just as important, what a visual inspection cannot tell you.

What is a visual inspection, exactly?

A careful, documented look at the array, done from the roof edge, a ladder and the ground, with photos of everything. Nobody walks on the panels. Nothing gets opened, unplugged or tested.

On our crew, the inspection lead does it and writes the notes. You get a photo report that says what was seen, where, and who should look at it next. It is the same glass-level check that comes with every wash, done as its own visit when you want it on its own. Our visual solar inspection service describes the visit and the report.

What do we look at on the glass?

The glass is the first thing light hits, so it gets the closest look:

  • Cracks. Straight lines, spiderweb patterns from an impact point, or hairline cracks running from a corner.
  • Chips and impact marks. Small pits or bruises, often clustered after hail.
  • Scratches. Usually from a past cleaning with the wrong tool.
  • Film and spotting. Dust, pollen, mineral rings from hose water.
  • Droppings and sap. Hard shading spots that rain will not move.

Cracked glass is not only a production issue. It can let moisture reach the cells over time. A crack always goes in the report with a photo and a recommendation to call the installer.

What can you see through the glass?

More than you would think, with the right light:

  • Browning or yellowing. Discoloration over the cells, often in patches. It usually means the material behind the glass is aging or was affected by heat.
  • Snail trails. Thin dark lines that wander across a cell. They are often a sign of fine cracks in the cell itself, which a visual check can flag but not measure.
  • Burn marks. Small brown or dark spots, sometimes at a cell edge or a ribbon. These go straight to the installer.
  • Bubbles or delamination. Places where layers inside the module have started to separate.

None of these are things you can fix by washing. All of them are things your installer will want to know about, ideally while the panel is still under warranty.

What about frames and racking?

The metal around and under the glass holds everything in place. We check:

  • Frames. Bent, dented or separated corners.
  • Clips and clamps. Anything loose, missing or visibly shifted.
  • Rails. Sagging, corrosion or damage at the ends.
  • Grounding hardware. Whether it is visibly present and attached. We note what we see, but testing it is an electrician’s job.

A loose clip is a small fix for an installer. Left alone through a few windstorms, it can turn into a module that shifts.

What about cables and connectors?

We look, carefully, at what is visible:

  • Hanging cables. Wires drooping below the array or resting on the roof surface.
  • Failed cable ties. Brittle or broken ties that let cables swing in the wind.
  • Damaged insulation. Chafing, cracks, or chew marks.
  • Connectors. Whether they look seated and dry, and whether they sit in debris.

We do not unplug, open, test or move any of it. If something looks wrong, we photograph it and send it to your installer or a licensed electrician. That line is firm on every visit.

What lives under the array?

The gap between the panels and the roof is where trouble hides. We look under every edge we can see for:

  • Nests. Pigeons above all. Our page on pigeons nesting under panels explains why.
  • Droppings and debris. Twigs, leaves, cottonwood fluff, needles.
  • Signs of chewing. On cables or roof materials.
  • Standing debris against mounts. Which can hold water against the roof.

We do not remove nests or install critter guards. We document what we find and recommend your installer or a wildlife specialist.

Do you check the roof?

Only what we can see around the array. Lifted shingles near a mount, missing flashing, a soft-looking spot, granules washing out of a gutter after a storm. Those go in the report with a note to call a roofer.

We are not roofers, and a visual note is not a roof inspection. It is a flag that someone qualified should take a look.

What does a visual inspection miss?

This is the honest part. A visual inspection cannot:

  • Measure electrical output of a single module or string.
  • Find heat problems that do not show on the surface.
  • Confirm hidden cell cracks that leave no visible trace.
  • Test grounding, insulation or connectors.
  • Certify anything for an insurer, lender or buyer.

That is why we pair what we see with what your data shows. If your monitoring app or panel-level data says one module is consistently weak, and the inspection finds a snail trail or a burn mark on that same module, that is a strong case to bring to the installer. If the data and the glass both look fine, you can relax.

When is an inspection worth booking?

A few moments come up again and again on the Front Range:

  • After hail. The storm check is a visual inspection timed for after a storm, with photos of every module for your installer and, if needed, your insurer. Start with our after a hailstorm checklist from the ground.
  • Before selling a home. The home sale solar report adds production history to the photos.
  • When your numbers dip. A slow slide with no obvious cause is worth a look.
  • Once a year, in spring. Before the long summer days, so anything found can be fixed in time. That is the spring report in year-round care.

If none of those apply and your numbers look normal, a yearly glass-level check during a wash is usually enough. Panels that look fine from the street and produce what they did last year rarely need a separate visit.

What does the report look like?

Plain language, photos and a recommendation for each item. A typical report covers:

  1. A summary. What we saw overall, in two or three sentences.
  2. Photos of every row. From the roof edge and the ground.
  3. Findings, one by one. Location, what it is, a close photo, and who should look at it next.
  4. Production notes. What your app shows, if you have shared read-only access.
  5. Next steps. Installer, electrician, roofer, insurer, or nothing at all.

If a word in the report is unfamiliar, our solar care glossary defines the terms we use.

What does it cost?

A visual inspection with a photo report starts from $129. A storm check after hail starts from $119, and a home sale report from $199. Every wash includes a glass-level check at no extra cost. Prices are indicative and confirmed once we see your roof.

The short version

  • A visual inspection looks at every module, the racking, the cables and the gap underneath.
  • It finds cracks, browning, snail trails, loose clips, nests and debris.
  • It cannot test electrical parts or certify anything.
  • Every finding goes to the right trade: installer, electrician, roofer or insurer.
  • It works best alongside your own production data.

If you would like a careful look at your array, you can book an inspection, and we will send back the photos and notes in plain language.
