Project Enif, Banda 70 MW Solar Plant: Achieving Higher Energy Yield with Intelligent Robotic Solar Cleaning

As utility-scale solar power plants continue to expand across India, maintaining module cleanliness has become one of the most important factors influencing long-term energy generation, performance ratio (PR), and return on investment. Dust accumulation, seasonal weather patterns, water scarcity, and labor-intensive cleaning operations can significantly impact plant efficiency when not addressed through a structured maintenance strategy.

The Banda Solar Power Plant in Uttar Pradesh faced these exact challenges. Operating across a large 70 MW ground-mounted solar installation, the project required a cleaning solution capable of maintaining consistent module cleanliness while reducing water consumption, minimizing operational complexity, and improving cleaning accountability.

Traditional cleaning approaches relied heavily on manual intervention, recurring water usage, and large maintenance teams. These methods often struggled to keep pace with seasonal dust accumulation and growing operational demands. Plant operators needed a more scalable and sustainable solution that could support long-term solar asset performance while reducing dependency on water and manpower.

To address these challenges, Taypro deployed one of its most comprehensive robotic cleaning ecosystems. The project includes 106 GLYDE Automatic Solar Cleaning Robots, 54 NYUMA Semi-Automatic Cleaning Systems, and the NECTYR Fleet Monitoring Platform. Together, these technologies create a fully integrated robotic cleaning environment designed specifically for utility-scale solar operations.

Today, the Banda project demonstrates how intelligent robotic cleaning technology can transform solar operations and maintenance. By combining automation, waterless cleaning, data-driven scheduling, and fleet visibility, the project has delivered measurable operational, environmental, and financial benefits while supporting higher energy generation and improved sustainability outcomes.

Project Overview

The Challenge: Solar Module Soiling in Uttar Pradesh

Utility-scale solar assets in Uttar Pradesh operate under environmental conditions that can significantly accelerate module soiling. Dust generated from agricultural activity, transportation corridors, construction movement, seasonal winds, and dry weather conditions gradually accumulates on module surfaces and reduces solar energy conversion efficiency.

For a 70 MW solar plant, even a small reduction in module cleanliness can result in considerable annual energy losses. Maintaining a consistent cleaning schedule therefore becomes essential for preserving plant performance and maximizing energy generation.

Before the implementation of robotic cleaning technology, conventional cleaning programs presented several operational challenges:

• High annual water consumption.

• Large labor requirements.

• Inconsistent cleaning frequency.

• Difficulty maintaining cleaning quality across large areas.

• Limited visibility into completed cleaning activities.

• Increased operational costs.

• Weather-related disruptions.

• Safety concerns during manual cleaning operations.

As the plant expanded its operational focus toward performance optimization and sustainability, it became clear that a more advanced cleaning strategy was required.

Taypro's Robotic Cleaning Solution

Following a detailed site assessment and operational analysis, Taypro designed a customized robotic cleaning solution tailored specifically for the Banda Solar Plant.

The deployment combines multiple technologies to create a comprehensive cleaning ecosystem:

• 106 GLYDE Automatic Robotic Cleaning Systems.

• 54 NYUMA Semi-Automatic Cleaning Units.

• NECTYR Fleet Monitoring and Analytics Platform.

• Waterless Dry-Cleaning Technology.

Rather than relying on periodic manual intervention, the robotic fleet provides consistent, repeatable cleaning cycles while enabling plant operators to monitor performance and cleaning activities through a centralized platform.

GLYDE Automatic Robots: The Foundation of Continuous Cleaning

The GLYDE Automatic Robot serves as the primary cleaning technology deployed throughout the Banda Solar Plant. Designed specifically for utility-scale solar applications, GLYDE robots perform scheduled cleaning cycles across fixed solar module rows while operating independently within assigned cleaning zones.

Each robot is engineered to perform efficient waterless cleaning using specialized brush systems that remove accumulated dust and debris without damaging module surfaces.

Key advantages of the GLYDE system include:

• Automated cleaning operations.

• Reduced dependency on manual labor.

• Consistent cleaning quality.

• Waterless cleaning technology.

• Predictable cleaning schedules.

• Improved cleaning frequency.

• Scalable deployment across utility-scale assets.

The deployment of 106 GLYDE units ensures broad coverage across the plant's operational footprint while maintaining cleaning consistency throughout the year.

NYUMA Semi-Automatic Systems for Flexible Coverage

While automatic robots handle the majority of routine cleaning operations, utility-scale solar plants often contain sections where additional flexibility is required.

To address these areas, Taypro deployed 54 NYUMA Semi-Automatic Cleaning Systems.

NYUMA units provide supplemental cleaning support for:

• Irregular table layouts.

• Transition zones.

• Special maintenance areas.

• Temporary operational requirements.

• Complex access locations.

• Sections requiring targeted cleaning.

This mixed-fleet approach allows the plant to combine the efficiency of automation with the flexibility needed for dynamic operating environments.

One of the defining features of the Banda deployment is the integration of Taypro's NECTYR Fleet Monitoring Platform.

NECTYR provides centralized visibility into robotic cleaning operations, allowing plant operators to monitor fleet performance, cleaning schedules, system status, and operational alerts through a single interface.

The platform supports:

• Fleet performance monitoring.

• Cleaning schedule management.

• Equipment diagnostics.

• Operational reporting.

• Alert management.

• Maintenance planning.

• Cleaning verification.

• Data-driven decision making.

Rather than relying on assumptions about cleaning completion, operators gain access to real-time operational data that improves accountability and maintenance efficiency.

Weather-Aware Cleaning Strategy

A common misconception about robotic solar cleaning is that robots clean every module every night. In reality, efficient utility-scale cleaning programs require intelligent scheduling that adapts to changing environmental conditions.

At Banda, cleaning operations are supported by weather-aware scheduling logic integrated through the NECTYR platform.

This approach considers:

• Dust accumulation rates.

• Rainfall forecasts.

• Wind conditions.

• Operational priorities.

• Fleet availability.

• Site-specific cleaning requirements.

Following effective rainfall, cleaning schedules may be adjusted to avoid unnecessary operations. During peak dust seasons, cleaning frequencies can be increased to maintain module performance and prevent excessive soiling losses.

This dynamic approach improves cleaning efficiency while reducing unnecessary equipment utilization.

Water Conservation and Sustainability Benefits

Water scarcity continues to be a growing concern for many solar power plants across India. Conventional wet-cleaning methods often require significant volumes of water throughout the year, creating both operational costs and environmental challenges.

By implementing Taypro's waterless robotic cleaning technology, the Banda Solar Plant reports approximately 9.8 million litres of annual water savings.

These savings provide multiple benefits:
