Stop Losing Solar Output to Dust: How Mars PT200 Protects Your ROI
PERTH, AUSTRALIA – September 2025 – The Mars PT200, a fully-automated PV trackless cleaning robot developed by Sunpure, is transforming solar operations by protecting investments and boosting energy output across rooftop and utility-scale projects.
Soiling—the accumulation of dust, dirt, and pollution on solar panels—quietly strips 10–15% of PV output every year, with losses even greater in arid and industrial environments. For a 2 MW solar site in Australia, that equates to approximately 280,000–420,000 kWh of lost generation annually, translating to A$70,000–A$105,000 in lost revenue.
The Mars PT200 addresses these inefficiencies with:
​
-
Trackless Operation – No rails required, enabling flexible deployment across rooftops and ground-mounted systems.
-
Water-free Cleaning – Sustainable, eco-friendly performance without excessive water use.
-
Scalability – Adaptable to commercial & industrial (C&I) as well as utility-scale PV projects.
-
Autonomous Navigation – AI-guided cleaning that adjusts to slopes, layouts, and challenging terrain.
-
Panel Protection – Brushless cleaning technology prevents micro-scratches, extending module life.
Proven Performance Across Challenging Environments
The Mars PT200 has demonstrated measurable results in diverse global projects:​
Tangshan, China (2.7 MW rooftop): Delivered a 19% power boost despite steep-slope rooftops and heavy cement plant pollution.
Changfeng, China (12.3 MW rooftop): Achieved fully automated nightly cleaning of 50,000㎡ of modules, sustaining stable output in dusty conditions.
Wenzhou, China (1.3 MW rooftop): Provided reliable operation in corrosive C5 environments with heavy metal dust and salt spray.
Jubail, Saudi Arabia (60 MW site): Successfully deployed 55 robots, delivering continuous efficiency at utility scale
Industry Perspective
​
Soiling losses represent one of the most significant hidden costs in solar operations. Without regular and effective cleaning, operators face reduced generation, lost revenue, and long-term module degradation. The Mars PT200 addresses these issues directly, converting inefficiencies into measurable performance gains while supporting operators’ sustainability objectives.
Future-ready Solar Maintenance
From rooftops to desert arrays, the Mars PT200 redefines solar O&M with autonomous, rail-free, and water-free cleaning technology. By addressing the industry’s silent revenue leak—soiling—the robot ensures every installed kilowatt delivers on its potential.
