At Wizard Wash Exterior Cleans, we provide specialist solar panel cleaning designed to improve efficiency, maintain performance, and protect your investment.

Solar panels rely on maximum light exposure to operate efficiently. Over time, dirt, dust, bird droppings, algae, and pollution build up on the surface, reducing the amount of sunlight reaching the cells. Regular professional cleaning helps ensure your system performs as it should.

​

Why Solar Panel Cleaning Matters

Even a thin layer of dirt can significantly reduce solar panel output. Neglected panels can suffer from:

• Reduced energy efficiency and output by up to 30%

• Localised “hot spots” caused by uneven soiling

• Long-term performance degradation

• Voided manufacturer warranties if cleaned incorrectly

Unlike windows or roofs, solar panels require specific cleaning methods to avoid damage.

​

How Our Solar Panel Cleaning Works

We use non-abrasive, manufacturer-safe methods specifically designed for solar panels.

1. Initial Assessment

We inspect the panels, access points, and surrounding roof area to determine the safest and most effective cleaning approach.

2. Pure Water Cleaning System

Using de-ionised, purified water, we gently remove dirt, grime, and contamination without leaving residue, streaks, or mineral deposits.

3. Soft Bristle Brushes

Specialist soft brushes are used to lift contamination without scratching the glass or damaging the panel surface.

4. Spot-Free Rinse

Panels are thoroughly rinsed and left to air-dry naturally, leaving a clear, streak-free finish that maximises light transmission.

​

Why We Don’t Use Pressure or Chemicals

Pressure washing and harsh chemicals can:

• Damage the panel surface or seals

• Cause micro-cracks in the glass

• Reduce efficiency

• Void manufacturer warranties

Our method is safe, controlled, and industry-approved.

​

How Often Should Solar Panels Be Cleaned?

For most domestic systems, we recommend cleaning once or twice per year, depending on:

• Roof pitch and orientation

We’ll always provide honest advice based on your setup.
