I’ve explained this in detail here:
👉 Sell Solar Energy Back to WAPDA – Gross / Net Billing Explained
What Changes Under Net Billing?
- Solar energy exported to the grid is credited at a lower, market-linked rate
- Imported electricity is billed at the full retail tariff
- Self-consumption becomes more valuable than export
This flips the old mindset. Solar is no longer about “sending units to WAPDA.” It’s about using every possible unit yourself.
Good News: Existing On-Grid Systems Are NOT Dead
One of the biggest myths I hear daily:
“If net metering ends, my on-grid system becomes useless.”
That is simply incorrect.
With the right engineering approach, existing grid-tied systems can be converted into high-productivity assets—even without exporting a single unit.
No-Export Operation: Maximum Productivity, Zero Policy Risk
The most immediate and compliant solution is deploying No-Export Devices.
How No-Export Works
- Solar generation is dynamically limited to match on-site load
- Zero power flows back to the grid
- DISCO permissions are not required for export
In multiple commercial retrofits I’ve executed, no-export control preserved 80–90% of daytime solar utilization while eliminating regulatory exposure.
This approach is especially effective for:
- Factories with steady base load
- Plazas and offices with daytime operations
- Institutions where export approval is delayed or denied
Advanced Solution: PCS + BESS for Grid-Independent Signaling
For larger and more sophisticated installations, we move one level up.
