Customer Success Story: Using the WLS-5 Solar Panel Cleaning Brush to Boost Income in 2025

As the global demand for clean energy continues to rise, solar panel owners are becoming increasingly aware of one critical issue—dust, sand, and pollution significantly reduce solar power generation efficiency. In 2025, with many countries pushing for higher renewable energy output, professional solar panel cleaning services have rapidly become a profitable small business worldwide.

Recently, one of our customers shared real photos of him using WLS-5 Solar Panel Cleaning Brush from Wuxi Wanlv Intelligent Technology Co., Ltd. to clean photovoltaic panels in his local area. By offering cleaning services to nearby solar farm owners and residential PV system users, he is now earning stable income every week.

A Growing Opportunity: Solar Panel Cleaning Is Becoming a New Income Stream

Globally, solar power installations in 2024–2025 have reached new highs, bringing a new trend:
More panels = More cleaning demand
More dust (especially in desert and coastal regions) = More power loss
More owners looking for reliable and affordable cleaning solutions

Industry data shows that dirty solar panels can reduce output by 15%–35%, and in some regions even more. This has created a booming market for affordable, efficient manual cleaning equipment—and this is exactly where the WLS-5 roller brush shines.
