Low generation can come from weather, shading, soiling, inverter downtime, string faults, grid outages, design assumptions or a genuine equipment problem. Compare measured data with the contract and a realistic expected range.
Make the comparison honest
Daily and monthly inverter generation.
System size, orientation and shading conditions.
Downtime or error logs.
Sales proposal or guaranteed-performance wording.
The small dashboard
For this case, the answer can change when daily and monthly inverter generation, system size, orientation and shading conditions, downtime or error logs, sales proposal or guaranteed-performance wording. Build a dated generation-versus-downtime table. Warranty or consumer claims are stronger when the technical shortfall is isolated from ordinary environmental variation.
Proof, not promises
Keep monitoring exports, electricity bills, site photos, commissioning report and warranty documents in one folder for this case. Name files with dates and retain original PDFs where possible.
| Record | Use it to verify | Why keep it |
|---|---|---|
| Monitoring exports | Daily and monthly inverter generation | Protects the decision if a portal, account screen or verbal explanation changes. |
| Electricity bills | System size, orientation and shading conditions | Separates a written fact from a sales statement. |
| Site photos | Downtime or error logs | Creates a dated record another reviewer can verify. |
| Commissioning report and warranty documents | Sales proposal or guaranteed-performance wording | Lets you challenge the exact field, charge, date or obligation. |
From question to action
- Pin down the first controlling fact: daily and monthly inverter generation.
- Reconcile it against monitoring exports and electricity bills.
- Test the decision under one realistic adverse case instead of assuming the best outcome.
- Record dates, reference numbers and the institution responsible for the next step.
- Escalate only the unresolved point; do not restart the case with a vague complaint.
Stop conditions
Pause before the next irreversible step if one cloudy month is treated as proof of a defective system, the vendor refuses to provide monitoring access, a performance promise has no stated assumptions.
- One cloudy month is treated as proof of a defective system.
