The 10-point solar AMC checklist
Read any AMC against these ten points. A contract that names each one in writing is a structured maintenance program; one that doesn’t is occasional service visits.
| # | Contract point | What to look for |
|---|---|---|
| 1 | Engineer visits | How often a solar engineer visits, and what each visit checks |
| 2 | Panel cleaning | How often panels are cleaned, and the method, matched to your site’s dust |
| 3 | Continuous inspection | Who watches output between visits, at string level, on your inverter brand |
| 4 | Fault detection and rectification | Which faults are fixed under the contract, and how quickly someone responds |
| 5 | Parts and replacements | What is included and what is charged separately |
| 6 | Service reports | A written report after every visit: observations, work done, recommendations |
| 7 | Performance reporting | Output reported against what the system should produce, not just raw units |
| 8 | Who you call | A named team or operations center, with hours and a response route |
| 9 | Systems covered | Whether the AMC covers a system another company installed |
| 10 | Term and renewal | Contract length, renewal and what happens at the end |
Why every solar system needs an AMC
A system doesn’t have to stop working to lose performance. Dust, loose connections, equipment faults, communication failures and gradual degradation reduce production long before anyone notices. In Lahore’s dry season, peer-reviewed measurements put soiling loss at about 0.8% of output per day at typical tilt, so a missed cleaning schedule shows up in the bill quickly.
The faults that cost most are the hidden ones. Across the solar Wattey SPC monitors, 61% of inverters had a dead string or went silent within 60 days while the owner’s app still showed a working plant (as of 25 August 2026). An AMC that only cleans panels never finds those.
What Wattey Energy’s AMC includes
Wattey Energy’s AMC keeps a system at its best with scheduled maintenance, routine engineer visits, professional panel cleaning, 24/7 solar inspection and intelligent energy monitoring. It is powered by Wattey Solar Performance Cloud (Wattey SPC), WattEY EMS, our own Network Operations Center (NOC) and experienced solar engineers.
- 24/7 solar inspection: Wattey SPC continuously inspects for hidden performance issues.
- Intelligent energy monitoring: WattEY EMS gives real-time visibility of electrical performance.
- Routine engineer visits: scheduled preventive maintenance.
- Professional panel cleaning: regular washing for maximum production.
- Fault detection and rectification: issues resolved before they cause major losses or downtime.
- Detailed service reports: observations, completed work and recommendations after every visit.

AMC or O&M: what’s the difference?
O&M (operation and maintenance) is the work: monitoring, cleaning, fixing and reporting. An AMC is the contract that commits a company to doing that work for a year at a defined scope. For a large commercial or industrial plant, the same work may run as a full O&M service; for most businesses and homes, the AMC is how it is bought.
