Cleaning solar panels regularly is crucial to maintaining optimal energy output, especially in regions prone to dust accumulation, pollen, or other environmental particulates. Manual cleaning methods can be labor-intensive, risky on large installations, and often water-intensive. Automated cleaning robots have emerged as an efficient, safe, and environmentally friendly alternative. In this article, we’ll explore key considerations when choosing a solar panel cleaning robot, review some of the top solutions on the market—including the industry-leading NXR-Ⅳ by Neexgent—and provide guidance for PV system operators seeking to maximize their return on investment.

The Impact of Soiling on Solar Panel Performance

Solar panels accumulate dust, bird droppings, pollen, and other debris—collectively referred to as “soiling”—which can reduce conversion efficiency by up to 30% in high-dust or desert environments. Researchers at the University of Houston estimate that the average soiling loss worldwide was at least 3–4% in , with localized losses far higher in arid regions. Even a 1% loss can translate to thousands of dollars of lost energy revenue annually for utility-scale installations. Therefore, systematic cleaning is not merely cosmetic but economically imperative.
