Solar Panel Cleaning & Bird Proofing

Why Combine Cleaning With Bird Proofing?

If pigeons or other birds have been under your solar panels, you almost always have two problems at once: the panels are soiled, and the birds are still there. Cleaning the panels without proofing the gap means the birds return within weeks and the mess builds up again. Proofing without cleaning leaves you with a protected array that is still underperforming.

The complete solution is to do both in a single visit: clear the gap and clean the panels, then fit a stainless mesh barrier so birds cannot come back. You end up with clean, protected panels that generate at full output — permanently.

How Birds Affect Your Generation

Bird droppings are acidic and opaque. When they build up on the panel glass they block light reaching the cells, and a heavily soiled array can lose 10–20% of its output. Because the drop is gradual, many homeowners do not realise how much they are losing until the panels are cleaned and generation jumps back up.

Droppings also etch the glass over time and corrode the aluminium frame, so the longer they sit, the harder they are to remove and the more likely they are to leave permanent marks.

The Combined Clean & Proof Process

1. Clear the gap — remove all nesting material, droppings, feathers and debris from beneath the panels.
2. Clean the panels — a low-pressure, pure-water wash with soft brushes lifts droppings and grime without damaging the anti-reflective coating or forcing water into the electrics.
3. Inspect cables — check the DC cables for pecked or chewed insulation.
4. Fit the mesh barrier — a stainless steel guard clipped to the panel frame seals the perimeter so birds cannot return.

Done in a single visit, this gives you a clean, protected baseline that lasts.

Why Not Just Clean?

A clean on its own is a short-term fix. The pigeons that soiled your panels will be back within days, and within weeks the array will be dirty again. The only way to keep panels clean long-term is to stop the source — the birds nesting underneath — with a proper barrier.

Why Not Just Proof?

If the panels are already heavily soiled, proofing alone leaves them underperforming. Bird droppings do not wash off in the rain (they are sticky and acidic), so the array will keep under-generating until it is properly cleaned. Combining the two restores full output straight away.

How We Clean Safely

We use low-pressure, pure (deionised) water and soft brushes. This is the industry-standard method for solar panels because:

• It does not force water under the panel frames or into junction boxes (which pressure washers do, causing faults).
• It does not scratch the anti-reflective coating on the glass.
• It leaves no chemical residue or streaks — pure water dries spot-free.
• It is safe for the roof and the environment.

We never pressure-wash solar panels, and we never use abrasive brushes or harsh chemicals.

The Proofing Barrier

The mesh barrier is welded stainless steel, fixed to the aluminium panel frame with specialist clips — no drilling, no roof contact, no scaffolding in almost all cases. It is rated for 10–15+ years and carries a 10-year workmanship guarantee.

Benefits of the Combined Service

• Restores generation — clean panels produce more power immediately
• Stops the cause — birds cannot return to nest and soil the panels
• One visit — clean and proof done together
• Warranty-safe — no pressure washing, no drilling
• Long-lasting — a clean, protected baseline for years
• Protects the glass — stops acidic droppings etching the surface

Common Mistakes Homeowners Make

The most common mistake is cleaning only — the birds return and the mess builds up again within weeks. The second is pressure-washing the panels, which can force water into the electrics and cause faults. The third is using harsh chemicals or abrasive brushes, which scratch the anti-reflective coating and reduce output.

Maintenance

After a combined clean and proof, upkeep is minimal. The mesh keeps birds out, so the panels stay clean for far longer. An annual rinse and a yearly visual check of the mesh is all most homes need.
