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.
