Discrepancy in rooftop billing
I recently noticed a discrepancy in my solar rooftop system readings and wanted to understand if this is normal or if there’s an issue.
I installed a 3.6 kW solar panel system around three months ago. On average, the system generates about 19–20 units per day. However, the export reading shown in the app is only around 13–14 units daily.
Initially, I assumed the export figure represented net export (total generation minus daytime consumption), but the app clearly labels it as “Total Export” and separately shows “Total Import.” So it doesn’t seem to be a net calculation.
There’s consistently a difference of around 6-7 units every day between the generated units and exported units. I’ve attached a screenshot for reference.
Can anyone explain how this is possible and whether this indicates a system issue, inverter setting problem, or meter discrepancy? Also, how can I rectify it if something is wrong?
