What Do You Use for Cleaning a Solar Panel? | Tools and Techniques

Solar panels are a real investment that has provided clean and sustainable electricity for years. Like any other outdoor equipment, solar panels are exposed to dust, dirt, bird droppings, and other environmental contaminants, which can reduce their performance over time. Cleaning regularly is necessary for optimal performance. In this tutorial, we'll try to cover all information about the most asked query “what do you use for cleaning a solar panel” and look at the exceptional tools, and procedures for cleaning solar panels with tips from Golden Rays Solar Cleaning Company specialists.

Why is Cleaning Solar Panels Important?

When solar panels become dirty or hindered by debris, the sunlight they capture decreases, resulting in lower energy generation. Studies have shown that accumulated dirt and contaminants can reduce performance by up to 25%. Over time, this can lead to significant energy loss and a worse return on investment. Keeping your solar panels clean ensures that they perform efficiently and last as long as possible.

How Often Should Solar Panels Be Cleaned?

Cleaning frequency varies according to location, weather conditions, and the presence of nearby pollutants. In general, panels should be cleaned at least twice a year. However, places prone to excessive dust, pollution, or bird activity may necessitate more frequent care. Golden Rays stands out among solar panel cleaning companies for commitment to enhancing panel efficiency and longevity with expert, and eco-friendly cleaning solutions.

Tools for Cleaning Solar Panels

Solar panels must be cleaned using specialist instruments that protect their sensitive surface. Here are the primary tools utilized by professionals:

Soft-Bristled Brushes and Sponges

Why It’s Used

Surface dust and debris can be removed with soft brushes or sponges that will not scratch the glass. 

Technique

Golden Rays professionals use soft-bristled brushes with telescoping handles to safely reach high panels. These brushes ensure that all panel portions are cleaned without damaging the delicate surface.

Deionized Water System 

Why It’s Used

Deionized water is mineral-free, making it excellent for achieving a spotless, streak-free surface. 

Technique

Solar panel cleaners can avoid hard water stains by using deionized water instead. This procedure ensures no chemical residue is left behind, which may lower panel efficiency. The deionized water system is handy for panels in hard water areas.

Squeegees

Why It’s Used

Squeegees help to remove excess water from the panels, resulting in a clean, dry surface. 

Technique

After washing the solar panels, squeegees remove any residual water droplets, preventing streaks and ensuring no moisture is left to attract fresh dust and debris.

Extension Poles

Why It’s Used

These poles allow cleaners to access high or difficult-to-reach panels safely.

Technique

Extension poles, which come with attachments for brushes and squeegees, allow professionals to clean panels without ladders or heavy climbing, lowering the danger of accidents.

Pressure Washers (Low Pressure)

Why It’s Used

Low-pressure washers are suitable for removing tight dirt while protecting the panel surface.

Can you power wash solar panels?

While pressure washers are typically avoided, Golden Rays advocates utilizing low-pressure washers built exclusively for solar panels. This enables effective cleaning without causing cracking or other damage to the panels.

Techniques for Effective Solar Panel Cleaning

Washing and Soft Scrubbing

Step-by-Step

Wash the panels with deionized water to remove dirt, then clean gently with a soft brush or sponge. The squeegee is then used to remove any remaining water. 

Benefits

This approach is simple but effective, safe for most panels, and leaves no residue or streaking. 

Two-Bucket Method

Step-by-Step

Cleaners use one pail of deionized water and another bucket to wash. The cleaning brush is dipped in soapy water to scrub the panels, while the second bucket helps wash and limit dirt transfer.

Benefits

The two-bucket procedure reduces cross-contamination and keeps panels cleaner, especially in regions where dirt accumulates. 

Biodegradable Soap and Water Solution

Step-by-Step

A light, biodegradable soap solution is applied to the panels to remove stubborn grime, which is then rinsed away with deionized water. 

Benefits

This eco-friendly method effectively removes oil, bird droppings, and sticky residues without harming the environment or the panels. 

Professional Vs. DIY Solar Panel Cleaning

While DIY cleaning may seem attractive, professional cleaning provides real benefits: 

Safety

Professionals like Golden Rays Solar Cleaning Company have the necessary training and solar panel cleaning equipment to safely reach and clean high or awkwardly placed panels.

Thoroughness

Professional cleaners use specialized tools, such as deionized water systems and telescoping brushes, to clean panels more thoroughly than household methods. 

Warranty Protection

Many solar panel warranties require professional cleaning. DIY approaches can occasionally void warranties if they cause damage. 

Common Mistakes to Avoid When Cleaning Solar Panels

Using Harsh Chemicals

Chemicals can degrade the protective coatings of panels, resulting in lower efficiency and a shorter lifespan. 

Applying Too Much Pressure

High-pressure washing can break panels, while hard scrubbing can damage the glass.

Cleaning During Peak Sunlight

Cleaning in direct sunlight may cause the cleaning solution to dry fast, producing streaks or residue.

Golden Rays Solar Cleaning Company recommends cleaning panels early in the morning or late evening for optimal results.
