Executive summary
The Sungazing plant is a 2.5 MW ground-mounted utility asset in India. Five NYUMA semi-automatic portables on 2.5 MW (~2.0 robots/MW) with inspection-led plans from 2025 commissioning. Taypro implemented Semi-automatic waterless cleaning under CAPEX.
Operations report roughly 350 thousand litres of water saved per year, about 93.8 MWh of additional clean generation, and 47 metric tons CO₂ equivalent (site-reported; validate with your SCADA).
Robotic cleaning means scheduled cycles and weather-aware holds—not flooding modules on a daily wash calendar.

Fleet design at 2.5 MW
Five NYUMA semi-automatic portables on 2.5 MW (~2.0 robots/MW) with inspection-led plans from 2025 commissioning.
Sungazing contrasts Khopoli and Chakan-VI automatic micro programmes—five portables prove waterless coverage without GLYDE on every row.
Operations rhythm with inspection-led accountability
Published weekly block plans and inspection sign-off drive accountability. Technicians own brush care, holds, and dated reschedules when telematics are not the primary layer.
Cleaning cadence: planned portable cycles and weather holds
NYUMA semi-automatic coverage on this site is driven by published weekly block plans, supervisor prioritisation, and inspection sign-off—not continuous daily washing of every hectare. Technicians execute waterless brush cycles when wind, rain, and site conditions are safe; wind holds apply, and passes are skipped or deferred after effective rain when glass is already rinsed.
Seasonal soiling still dictates intensity: busier months concentrate portables on downwind edges, haul-road strings, and blocks with the steepest inverter trends—often comparable in frequency philosophy to the 3–10 cycles per month band used on automatic peers, without implying one robot pass per module per night. See semi-automatic systems and cleaning technology.
Commissioning and handover
Commissioning sequenced high-soiling blocks first, validated geometry and docking or staging, and trained technicians on waterless compliance and hold rules.
What Sungazing teaches owners at 2.5 MW
Sungazing contrasts Khopoli and Chakan-VI automatic micro programmes—five portables prove waterless coverage without GLYDE on every row. Use the ROI calculator with conservative GWh attribution and utility operations framing.
Lenders should request block-level proof: signed inspection sheets and weekly block plans. Pair 350 thousand litres, 93.8 MWh, and 47 tCO₂e on one assumption set.
Regional soiling at 2.5 MW
Site-specific dust on a 2.5 MW portable-first table. Downwind rows soften in inverter data before drive-by inspections; programmed cleaning with block proof beats episodic tanker washes.
Before Taypro, manual programmes struggled with frequency, water logistics, and auditability on 2.5 MW tables.
Monthly operating calendar
Jan–Feb: review brush wear and cycle plans. Mar–Jun: peak dust—scheduled density toward 6–10 cycles per month class on automatic peers where applicable; not nightly full-plant wash. Monsoon transition: stand down after effective rain. Post-monsoon: re-walk paths after civil or vegetation works.
SCADA correlation
Pair inverter trends with inspection timestamps. If PR stays soft after logged cleans, investigate brush wear, partial coverage, or equipment fault.
Water and finance narrative
Model 350 thousand litres avoided against tanker and wet-wash baselines. Stress-test 93.8 MWh at 50% and 75% attribution before sign-off.

ESG and insurer pack
Include night traffic plans, training records, and sample inspection weeks with water and carbon slides on consistent assumptions.
Procurement checklist
- Row repeatability map before copying robots/MW from this case study.
- Manual baseline year for water and labour.
- Block-level completion proof requirement in contracts.
- Phase commissioning on highest-soiling blocks first.
- Read cleaning technology and performance methodology.
Who should benchmark Sungazing?
Owners with 2.5 MW India assets and semi-automatic constraints—not plants copying fleet counts without maps.
How many cycles per month?
Site-specific; commonly roughly 3–10 dry cycles per month, weather permitting—not daily washing of every module.
Seasonal operating calendar
Jan–Feb: review brush wear and cycle plans; validate wind and rain hold rules in NECTYR or inspection logs. Mar–Jun: peak dust—scheduled cycle density increases on priority blocks (weather permitting), often toward the 6–10 cycles per month class for automatic fleets; not nightly coverage of every module. Monsoon transition: stand down or lighten cycles after effective rain; inspection-heavy weeks where appropriate. Post-monsoon: re-walk paths after vegetation or civil works; update block timers before the next approved cleaning window.

Technical committee closing brief for Sungazing
Attach row maps, inspection samples, and conservative 93.8 MWh / 47 tCO₂e stress tests. 350 thousand litres water avoided should use the same assumptions as generation slides.
Scheduled cycles and weather-aware holds—roughly 3–10 dry cycles per month on automatic peers, weather permitting—not daily plant-wide washing. Read cleaning technology and performance methodology.
Compare peers linked above; request layout review via contact when row maps are preliminary.
Finance workshop agenda
Validate manual baseline; agree PR normalization; review inspection cadence; align ESG water and carbon on one assumption set; budget spares and training through year five.
Operations FAQ
How are cycles scheduled?
Weekly NYUMA block plans and inspection sign-off—not a daily wash of the full plant.
What should lenders review?
Water statistics, inspection sheets, training records, and GWh stress tests at 50% and 75% attribution.
Operations evidence summary
Owners should validate reported water, generation, and carbon statistics with local SCADA and tariffs; pair this 2.5 MW case study with performance methodology, the projects hub, and the ROI calculator. Scheduled cycles and weather-aware holds—not plant-wide daily washing—define Taypro utility programmes.
Compare Soyegaon, Chhayan, and tier-1 peers before copying robot density. Block-level proof—inspection sign-off—belongs in lender packs alongside 350 thousand litres and 93.8 MWh stress tests at fifty and seventy-five percent attribution.
