Changes in Pakistan's solar billing policy

Net Billing Makes it No More Beneficial to Sell Solar Energy Back to WAPDA

NEPRA’s net-metering pause decoded. A practical guide to net billing, no-export solar, PCS+BESS, hybrid inverters, and future-proofing solar in Pakistan.

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.

Using a Power Conditioning System (PCS) with a Battery Energy Storage System (BESS), existing on-grid inverters can be made functional even without live grid reference.

What’s Actually Happening Technically?

  • The PCS generates a synthetic grid signal
  • Voltage is provided 180° apart and 120° out of phase (3-phase simulation)
  • On-grid inverters “see” a grid and continue producing
  • Energy is absorbed by loads and/or batteries

This is not theory. We’ve deployed it in controlled industrial environments where grid export was legally or technically impossible.

Result: Existing assets keep earning value instead of becoming stranded.
