We use safe, purified water and soft-bristled poles to gently lift grime without scratching or damaging your panels. Clean panels = more power, better savings, and longer-lasting equipment.

Why Clean Your Solar Panels?

Solar panels are exposed to the elements 24/7. Over time, they collect:

Bird droppings
Dust and pollen
Moss, algae, and lichen
Tree sap and pollution

This buildup creates a film that blocks sunlight — reducing the efficiency of your system by up to 20–30%. Regular cleaning restores performance and prevents damage to panel coatings or seals.

Key benefits of cleaning:

Improve solar output and energy savings
Maintain manufacturer warranties
Prevent long-term surface damage
Extend the lifespan of your system
Keep your panels looking pristine

Frequently Asked Questions

Will cleaning my solar panels really make a difference?

Yes! Dirty panels can lose up to 30% efficiency. Cleaning restores their ability to absorb sunlight and improves energy output.

Is it safe to use pressure washing?

No — pressure washing can damage seals and void warranties. We use low-pressure, soft-pole cleaning and purified water only.

What is pure water and why is it better?

Pure water contains no minerals or particles. It dries clean without streaks or residue and doesn’t harm your panels’ surface.

Do I need to be home during the clean?

Only if we need internal access. For rooftop panels, you don’t need to be present — just allow safe exterior access.

Can I clean them myself?

We don’t recommend it. Accessing roof panels can be dangerous, and DIY tools may scratch or damage the surface. Leave it to the pros!

Can I combine this with other cleaning services?

Yes — many customers combine this with roof cleaning, gutter cleaning, or window cleaning for full exterior care.
