PR loss of one percentage point costs you ₹50-80 lakh per MW per year. Our O&M AMC keeps PR ≥78% with seasonal cleaning, 24×7 monitoring, annual electrical inspection, and full warranty + insurance documentation.
A solar plant is a 25-year asset. Skipping O&M doesn't just lose generation — it forfeits warranty rights, insurance claims, and resale value.
4-6 cleaning cycles per year (state-specific). Pre-monsoon, mid-monsoon, post-monsoon, winter haze cycles. Desalinated water for coastal sites.
Sungrow iSolarCloud / Huawei FusionSolar continuous monitoring with API export. Real-time fault alerts to our 24×7 service center.
On-site inspection every quarter. Monthly performance reports with PR trends, energy yield, fault history, recommendations.
7-day PR measurement annually for warranty + insurance documentation. Independent third-party verification on request.
Cabinet cleaning, fan filter replacement, anti-islanding test, earthing resistance test, surge protection device replacement.
Manufacturer warranty claim coordination, replacement scheduling, insurance claim documentation. We handle the paperwork.
Indian solar plants face highly variable seasonal conditions. Our O&M calendar is tuned to your geography.
Inherit from EPC firm or take over existing plant. Asset audit, baseline PR measurement, document handover, monitoring system handshake.
Site-specific calendar with cleaning frequency tuned to your atmospheric exposure (coastal, chemical, mining, urban-haze, monsoon-belt).
24×7 SCADA tracking, fault response within 4-12 hours, monthly performance report with PR + energy + fault analytics.
Cleaning, visual inspection, electrical safety check, thermal scan (annually), photo documentation for insurance + warranty records.
IEC 62446 PR baseline measurement, warranty claim coordination, insurance renewal support, year-end report.
You don't have to have built with Sun Wave to use our O&M. We take over plants from any EPC firm — including ones that have exited the market or under-performed.
Common scenarios: original EPC went bankrupt; existing O&M provider missed PR commitments; plant was self-built and now needs professional management; portfolio operator wants standardised O&M across multi-site plants from different EPCs.

PR (Performance Ratio) loss of 1 percentage point costs ₹50-80 lakh per MW per year in foregone savings. Inadequate cleaning typically causes 2-5 percentage points of PR drop — meaning ₹1-4 Cr per MW per year of lost savings over the asset life. Professional O&M at ₹3.5-7 lakh per MW per year is the most cost-effective protection of solar plant value, plus essential for warranty + insurance claim documentation.
1.0-1.5% of capex annually for sites with standard atmospheric exposure (NCR, Bengaluru, Pune); 1.5-2.0% for high-particulate exposure (chemical clusters, mining-adjacent, coastal); 2.0-2.5% for premium service (data centres, hospitals, premium hospitality). For a 1 MW plant at ₹3.5 Cr capex, annual O&M is ₹3.5-7 lakh.
(1) 4-6 cleaning cycles per year (state-specific), (2) 24×7 SCADA monitoring with iSolarCloud / FusionSolar, (3) quarterly on-site visits, (4) monthly performance reports, (5) annual PR baseline measurement per IEC 62446, (6) annual electrical inspection (insulation resistance, IV curve, anti-islanding test), (7) inverter cabinet cleaning + filter replacement, (8) earthing system test, (9) surge protection device replacement after lightning events, (10) manufacturer warranty + insurance claim management.
Frequency depends on location: 4-6 weeks in NCR/Indo-Gangetic Plain (high dust), 6-8 weeks in inland Maharashtra/Karnataka/AP/TN, 4 weeks in coastal sites with salt + chemical exposure (Vapi, Hazira, Kochi, Aroor), monthly to quarterly in cleaner inland sites. The right schedule is determined by site-specific atmospheric exposure assessment, not generic.
Yes. As your O&M partner, Sun Wave coordinates manufacturer warranty claims for modules, inverters, and structures throughout the AMC term. We maintain commissioning records, annual PR baselines, cleaning logs, and inspection reports — exactly what manufacturers demand to honor warranty claims. ~70% of industry warranty claim rejections are due to inadequate documentation; we eliminate this risk.
Minimum 5 years bundled with the EPC contract. For long-term protection, 10-25 year extended O&M AMCs are recommended — they ensure continuous documentation, warranty pass-through, and consistent service quality across the full asset life. Sun Wave offers 5-year, 10-year, 15-year, and 25-year O&M structures with annual escalation typically at 4-5%.
