Application Site: 5MW Rooftop Plant in Mumbai

  • Key Features:
    • Dual-mode cleaning (dry/wet) for mixed pollution (dust + industrial residue)
    • 18kg lightweight design with foldable wheels for rooftop access
    • 4K camera with debris recognition (identifies bird droppings, cement particles, etc.)

Implementation:

  • 8 units serving 25,000 panels across 12 buildings
  • Semi-automatic operation via tablet (1 operator controls 3 robots simultaneously)
  • 30-minute quick-change battery system for continuous work

ROI Analysis:

  • Payback period: 14 months (vs 22 months for manual cleaning)
  • Achieved 21.5% efficiency recovery during monsoon smog periods
  • Reduced insurance claims for fall accidents by 100%

Comparative Advantage

FactorDesert ModelUrban Model
Cleaning CycleFixed dailyOn-demand (2-4x/week)
Speed0.8m/s0.5m/s (precision mode)
Slope Adaptability≤25°≤40° (for complex rooftops)
Data OutputPerformance logsTime-lapse cleanliness reports

Industry Feedback:

  • NTPC Ltd reported 23% reduction in module degradation rate after 18-month deployment
  • Tata Power achieved 102% IRR through combined use of both models in hybrid plants

Environmental Impact:

  • Equivalent to planting 8,700 neem trees annually in desert deployments
  • Prevented 450 tons of chemical cleaner discharge in urban areas
