SOLAR ROOFTOP OPERATIONS & MAINTENANCE (O&M) SERVICES
O&M stands for “Operations & Maintenance”—running and taking care of something. For solar power, O&M is a professional service package that keeps rooftop solar systems working smoothly and protects them throughout their lifetime.
There are different ways to handle solar system maintenance:
- Preventive Maintenance: Regular checkups and care to stop problems before they start, avoiding breakdowns or lost production.
- Corrective Maintenance: Fixing issues after they happen to get the system back up quickly.
- Condition-Based Maintenance: Using real-time data to predict problems and decide what needs attention first.
Once a rooftop solar system is installed and connected, it needs ongoing operations support to work properly. After that, regular maintenance is key to keep it running smoothly, reduce risks, and make equipment like panels and inverters last longer. Investors care most about running the system in a way that manages costs well and keeps everything efficient.

ON Energy’s Solar O&M Services Include:
- Panel Cleaning: Using special tools to clean solar panels.
- Roof Leak Protection: Fixing leaks on factory roofs with solar systems.
- System Upgrades: Improving solar setups to meet standards.
- Equipment Fixes: Replacing parts or repairing small issues during the warranty period, based on technical advice.
- Asset Management for Rooftop Solar Systems:
- Managing the entire solar system to ensure safety and top performance (keeping PR and Availability metrics high).
- Handling paperwork and working with authorities on behalf of the owner.
- Managing transformers (110kV, 220kV) and maintaining spare parts storage.
- Yearly scheduled maintenance for panels, inverter stations, transformers, control rooms, etc.
- Providing daily, monthly, yearly, maintenance, and incident reports.
