What Types of Panels and Roofs Can We Clean?

Residential and Commercial Rooftop Panels

Residential Rooftop Solar Panels

We specialize in rooftop residential systems, and start with a thorough panel inspection to identify cracks and loose wires. When it comes to cleaning, we use reverse osmosis or deionized, purified water and soft-bristled water-fed poles to preserve the integrity of your panels.

Suppose you have a severe buildup. In that case, we apply a biodegradable detergent at a 1:20 dilution and let it sit for three to five minutes. Next, we use a soft brush while closely monitoring to prevent streaks or chemical residue.

Our trained crew can also clean ground-mounted panels and elevated panels on churches and commercial buildings. You can even call us for a panel or roof wash service that requires harnesses, lifts, or complex access strategies.

Our Proven
Solar Panel Cleaning Process

Let’s see how solar panel cleaning in San Antonio, TX works: 

Site Assessment and Safety Preparation

Before we arrive, you should power down your solar panel system. Our crew may inspect your panels in person or via submitted photos. We’ll bring ladders, water poles, and safety gear for an efficient service. A dedicated technician will water your landscaping before, during, and after the job to prevent detergent damage.
1

Safe Roof Access and Pre-Clean Setup

Our crew uses ladders or roof-walk gear as needed. Harnesses and fall arrest systems help us ensure safety when working at heights. We may establish a safety perimeter around commercial or public buildings and protect your fragile surfaces with soft ladder attachments and non-invasive techniques.
2

Pure Water Cleaning and Final Inspection

We use soft-bristled brushes and RO/DI purified water for grime and debris removal from your panels. For stubborn buildup, we use a 1:20 detergent solution for three to five minutes with gentle brush agitation. A thorough final rinse ensures a streak-free finish.

After the job, our technicians invite you for a walkthrough to confirm your satisfaction. We send an invoice via Jobber CRM and accept payment online or in person.

Another wonderful job by Bellows Window Cleaning! My house is so bright now. Great communication, on-time arrival and so professional. My third time using them but certainly not my last!
Response from the owner:Thank you so much, Melissa! It was a pleasure working with you 🙂
I have used Bellows Window Cleaning since Daniel first started the business, almost two decades ago. Although I have to pay a small travel fee because I live in Kerrville, I have found that Tom and his crew do a far superior job than my local window cleaning companies. Their willingness to clean the high windows, inside and out, is not something the locals will do. His prices are very competitive and his results are outstanding. I subscribe to 6-month service, now.
Response from the owner:Thank you so much, Marian! We truly appreciate your loyalty and support over the years—it means the world to us! We’re glad to hear that Tom and the team continue to provide the high-quality service you deserve, even with the extra travel. Ensuring your windows shine inside and out is our priority, and we’re grateful to have you as a valued 6-month service subscriber. Looking forward to keeping your windows spotless for years to come!
