Why Solar Panel Cleaning is Critical for Maximizing Your Energy ROI?

       By the end of 2024, the cumulative global installed photovoltaic(PV) capacity reached a staggering 2.26 TW, which is equivalent to 2,260,000 MW of photovoltaic installed capacity. Converted at a rate of 150 W per square meter of photovoltaic panels, this amounts to 15,067 square kilometers.

       The rapid expansion presents of the photovoltaic industry immense opportunities for components and applications. For example photovoltaic panels, controllers, inverters, and related photovoltaic application appliances have all seen new opportunities and growth points.

It also unveils a massive, often overlooked market:

PV cleaning and maintenance.

       Solar panels are designed to harness nature's power, but they are also exposed to its elements.

       Large-scale centralized photovoltaic power stations need to be widely distributed in deserts, gobi, hillsides, fish ponds, etc. Small-scale distributed photovoltaic systems can use existing buildings to install photovoltaic panels, such as factory rooftops, house rooftops, carports, agricultural greenhouse roofs and walls, etc. 

       Due to factors such as sandstorms, dust, and bird droppings, will affect solar panels’surface to reduce power generation efficiency.

• Dust & Sand: Accumulates steadily, blocking sunlight.
• Bird Droppings: Cause localized hot spots and permanent damage.
• Pollen & Pollution: Create a stubborn film that drastically reduces light transmittance.

        This soiling isn't just a cosmetic issue; it's a direct drain on your revenue. A layer of grime can reduce a system's efficiency by 10-30% or more. For an aging project, regular cleaning can restore this lost performance, making it the most effective and cost-efficient way to boost energy yield from existing assets.
