Path-Q Solar
What should I do first if my electricity bill does not fall after solar installation?
Answer
First compare the bill period with the system's actual production and commissioning date, rather than assuming the panels failed. Check whether the array is operating, whether consumption or bill rates changed, and whether fixed charges or export treatment obscure the reduction.
Key points
- Review monitoring data for production, alarms, and gaps.
- Compare pre- and post-installation usage, not only total bill amount.
- Confirm the system was approved, energized, and connected as expected.
What it depends on
- System commissioning and billing dates
- Actual production and household consumption
- Bill structure, rates, and export treatment
- Seasonal weather and changes in occupancy or appliances
Risks and trade-offs
- A lower energy charge can be hidden by higher consumption or fixed charges.
- A monitoring display may be inaccurate or disconnected.
- Delaying investigation can extend production loss if there is an equipment or connection fault.
Information you may need
- Bills before and after installation
- Monitoring production and alarm records
- Commissioning or permission-to-operate information
- Recent changes in usage, rates, or billing arrangement
Your next step
What to do next
Collect the first comparable bills and monitoring data, then ask the installer or utility to investigate any gap between actual production and expected operation.
