Expert Solar Panel Cleaning in Oshawa To Maximize Energy Output
Your solar panels can quickly rack up spring pollen, fall leaves, winter dust, algae, and other debris in Ontario’s seasonal climate. The result is that not enough sunlight will reach the photovoltaic cells, and your system won’t produce sufficient power to run your household.
For this reason, you must clean your solar panels regularly to maintain optimal efficiency and ensure the buildups don’t eat away at the material over time. See-More Window Cleaning, a trusted, experienced provider of professional solar panel cleaning in Oshawa, ON, can help boost your panel efficiency and ROI.
We handle both residential and commercial solar panel washing services using a manual water-fed pole system with purified water. This protects all panel materials from harsh chemical damage. Ladders and telescoping poles ensure safe cleaning for hard-to-reach areas.
Our visual inspections during the service help identify cracks or issues before they become costly.

Solar Panel Cleaning Costs Transparent and Honest Pricing
Service Pricing Breakdown
- Small Residential Systems: Start at $250
- Typical Residential Range: $200–$800
- Large Commercial Jobs: Up to $8,000 for campuses, colleges, or multi-roof systems
We calculate pricing based on:
- Number of panels.
- Type of property (residential rooftop, commercial rooftop, or ground-mount).
- Accessibility (e.g., ladder access, roof pitch, or panel placement near the roof edge).
- Safety requirements, such as harnessing for low-parapet rooftops.
You’ll typically supply water. In some cases, we bring a buffer tank with approximately 100 gallons to the site to handle “drip-fed” cleaning setups.


Solar Systems We Clean
Rooftop to Ground Mount

Residential Rooftop Panels
Most residential solar panel cleaning jobs require ladder access, which can be complex depending on the roof design. In that case, we complete the tasks manually using a purified water-fed pole system. We may clean some panels from the ground, depending on the pitch and height.

Commercial Rooftop Systems
Most Oshawa commercial roofs are flat, allowing for safe movement during cleaning. For commercial solar panel cleaning in Oshawa, ON, our technicians use harnesses when working within six feet of an unprotected edge to minimize risks. We hand-clean your panels with purified water. Our commercial clients are often able to measure energy output improvements immediately after the service.

Commercial Ground-Mount Systems
We efficiently clean these easy-to-access systems with the same purified water-fed pole method. We often find them in schools, industrial sites, solar farms, and corporate campuses.
