The right solar architecture for every site
No two facilities are alike. We engineer the system type around your load, roof or land, and power-reliability needs.
Grid-tied systems that cut your electricity bill by offsetting daytime consumption, with net-metering where available.
Battery-backed standalone systems that deliver power where the grid is weak, absent or unreliable.
Solar combined with battery storage for backup, peak shaving and maximum self-consumption.
Larger-scale arrays on open land with optimised tilt, tracking options and scalable capacity.
Solar shade structures over parking and walkways — generation without using extra land, with EV-charging readiness.
Solar-fed charging hubs and canopies that power fleets and visitors with your own clean energy.
From survey to switch-on in five clear stages
The same disciplined sequence on every project — so you always know what's happening and what's next.
Survey & Assess
Site visit, load profile, shadow & roof-strength study.
Design
Yield simulation, layouts, SLD and structural design.
Procure
Certified modules, inverters and balance-of-system.
Install
Safe, quality-checked installation by our own crews.
Commission
Testing, approvals, handover and monitoring go-live.
How Zigma manages Solar AMC & O&M, end to end
A continuous loop — onboard, monitor, inspect, fix, report, improve — run by one team that knows your plant.
- 01
Onboard
Plant audit, baseline performance and a documented maintenance plan.
- 02
Monitor
Daily generation tracking and alarms, down to string level.
- 03
Inspect
Scheduled cleaning, thermography, IV-curve and electrical checks.
- 04
Fix
Fast fault diagnosis, spares and OEM / warranty coordination.
- 05
Report
Clear monthly performance and loss analysis you can act on.
- 06
Optimise
Recommendations on cleaning cycles, repowering and upgrades.
Every kilowatt-hour you paid for, actually delivered.
A solar plant that isn't maintained quietly loses output — to soiling, hot-spots, loose connections and inverter faults. Because these losses are gradual, they rarely trigger an alarm. Our AMC and O&M teams hunt them down on a schedule and fix them before they show up on your bill.
We operate plants we built and plants we didn't — every site gets a documented maintenance plan, a named engineer and a clear monthly report.
What every O&M plan covers
- Scheduled module cleaning
- Thermal imaging of panels
- String-level fault detection
- Inverter health checks
- Earthing & protection tests
- Monthly performance reports

What our O&M team does for your plant
Preventive Maintenance
Scheduled inspections, torque checks and cable & junction-box care that stop small faults becoming outages.
Module Cleaning
Cleaning cycles planned around your local dust, bird-dropping and soiling patterns to recover lost output.
Thermal & IV-Curve Testing
Thermography and IV-curve tests reveal hot-spots, mismatch and degrading strings before they cost you.
Inverter & Electrical Care
Inverter servicing, ACDB/DCDB checks, earthing and lightning-protection tests for safe, stable output.
Remote Monitoring
Daily generation tracking, alarms and string-level insight, so under-performance is caught early.
Breakdown Response
Fast fault diagnosis, spares planning and OEM / warranty coordination to cut downtime.
How Zigma manages Expertise & Inverters, end to end
From choosing the right inverter to keeping it healthy and renewing it — handled by the same engineers throughout.
Assess
We study your load profile, site and grid conditions before recommending anything.
Select
We weigh string, central, hybrid and off-grid options against your goals and explain the trade-offs.
Supply
Certified equipment is sourced and spares are planned up front, so downtime stays short.
Install
Our own field engineers install, configure and test the inverters, then commission them safely.
Service
Scheduled health checks, firmware updates and diagnostics keep output stable year after year.
Renew
When units age or fail, we plan repowering or replacement to restore full yield.
Why industry trusts Zigma with its solar
Two decades of electrical and power engineering sit behind every solar system we deliver.
In-house engineering
Design, SLDs and structural checks done by our own electrical engineers — not outsourced.
Power-systems depth
Solar, UPS, BESS and EV charging under one roof means your plant integrates cleanly with everything else.
Own field teams
Trained installers and technicians on our own payroll for consistent quality and safety on site.
Safety & standards
IS/IEC-aligned practices and an ISO-aligned quality process on every engagement.
Lifecycle accountability
The team that builds your plant is the team that maintains it — no hand-offs, no finger-pointing.
24×7 response
A real emergency line backed by engineers, so a breakdown becomes a short pause, not a long outage.
Approvals & compliance
Support with DISCOM applications, net-metering paperwork and statutory documentation so projects don't stall.
Data-driven monitoring
Generation data and alerts reviewed by engineers, turning raw numbers into fixes and clear reports.
Built for Indian conditions
Designs that account for heat, dust, monsoon and grid variability — not just textbook assumptions.
The brain of your solar plant — supplied, serviced and renewed
Inverters convert your panels' DC output into usable AC power. Pick the wrong one, or neglect it, and the whole plant under-delivers.
String Inverters
Modular and easy to service. Multiple MPPT inputs cope with varied roof orientations and partial shading.
Rooftops · commercial buildingsCentral Inverters
High-capacity units with centralised servicing, suited to large ground-mounted and captive plants.
