01 Oct Transforming Solar Operations at Scale

Rolas [Chara Dynamics Pvt Ltd]

Robots that work for you

Rolas delivers waterless, automated solar panel cleaning solutions that maximize energy output, cut costs, and empower sustainable growth for solar asset owners.

The Problem

Societal Challenge Rolas Addresses

• Water Scarcity: Solar plants currently rely heavily on water-based cleaning, depleting precious groundwater in already arid regions.
• Energy Efficiency Loss: Dust and dirt on panels reduce efficiency by up to 40%, lowering clean energy output.
• High Operational Costs: Manual cleaning is labour-intensive, risky, and unsustainable at scale.
• Climate Responsibility: Wasting water to clean green energy assets creates an environmental paradox that needs immediate resolution.

The Solution

• Waterless Cleaning Technology – eliminates water dependency, addressing critical scarcity issues.
• Automated Operations – reduces manual labor, improves safety, and ensures consistent performance.
• Customizable Deployment – adaptable to rooftops, utility-scale sites, and single-axis trackers.
• Smart Dashboard – enables single-click monitoring, reporting, and fleet management across sites.
• Durable & Lightweight Design – weatherproof, rust-proof, and built for long-term use with minimal maintenance.
• Scalable Model (RaaS) – cost-effective Robotics-as-a-Service ensures affordability and faster adoption.

Impact

• 6m Utility-Scale Robot at TATA Power – Successfully deployed for India’s #2 solar player, delivering waterless cleaning across large plants.
• Single-Axis Tracker Solution for ReNew Power – India’s #3 solar company benefited from Rolas’ robust tracker-specific robots, ensuring uninterrupted operations.

• Water Conservation – Each robot saves thousands of liters of water annually by eliminating water-based cleaning.
• Enhanced Energy Yield – Consistent cleaning increases solar panel output by up to 7–10%, driving higher returns for operators.
• Scalable Deployments – Proven operations across rooftops and utility-scale plants, showcasing adaptability across diverse customer needs.
