Solar Panel Cleaning Market Opportunity, Growth Drivers, Industry Trend Analysis and Forecast 2026-2035

The Global Solar Panel Cleaning Market was valued at USD 1.22 billion in 2025 and is estimated to grow at a CAGR of 3.5% to reach USD 1.72 billion by 2035.

Market growth is fueled by the need to maintain optimal solar panel performance, advances in cleaning technologies, and large-scale solar adoption worldwide. Solar panels accumulate dust, pollen, industrial pollutants, and debris, which can significantly reduce efficiency if left unaddressed. Cleaning solutions have evolved from manual washing to autonomous robotic systems, dry-brush methods, and electrostatic dust removal technologies. Government-supported research initiatives promote anti-soiling coatings and robotic cleaning innovations, enhancing efficiency while minimizing environmental impact. Regions facing water scarcity, including the Middle East, parts of North Africa, India, and the southwestern U.S., are increasingly turning to waterless and dry-robotic cleaning solutions. Sustainable cleaning approaches not only conserve water but also support large-scale solar farm operations in arid zones. Rising adoption of utility-scale solar farms, often covering hundreds of acres, further strengthens demand for automated, efficient, and eco-friendly cleaning solutions.

The wet cleaning segment is forecasted to reach USD 1 billion by 2035. Wet cleaning, using water and mild detergents, effectively removes stubborn debris such as pollen, industrial dust, and other contaminants. Studies indicate that wet cleaning can restore 2-5% more panel efficiency compared to dry methods under heavily soiled conditions, which is critical for maintaining peak energy output. Modern wet cleaning approaches are increasingly integrated with autonomous systems and smart water management, allowing precise application of demineralized water and reducing consumption by up to 90% compared to traditional manual washing. These technologies ensure effective maintenance while aligning with environmental sustainability and cost-efficiency goals.

The semi-automated segment is expected to grow at a CAGR of 5.5% by 2035. Semi-automated systems blend human oversight with mechanized tools, offering an efficient yet cost-effective alternative to fully robotic cleaning solutions. These systems, including motorized brushes and portable cleaning machines, are versatile and adaptable to varied panel layouts such as rooftop installations, ground-mounted arrays, and tilted solar modules. By combining efficiency with flexibility, semi-automated tools deliver faster, more uniform cleaning results, making them ideal for mid-sized solar farms that need operational reliability without large capital investments.

U.S. Solar Panel Cleaning Market is anticipated to reach USD 138 million by 2035. The country experienced robust solar capacity expansion, with utility-scale installations leading the growth. Dust-prone states and regions with low rainfall face efficiency losses exceeding 30% due to soiling, which drives demand for automated and water-efficient cleaning solutions. Incentives from policies such as the Inflation Reduction Act promote large-scale solar development and preventive maintenance programs, indirectly supporting the solar panel cleaning market. The U.S. market emphasizes water-saving technologies, robotic cleaning systems, and scalable maintenance solutions to optimize energy generation from expanding solar assets.
