Net metering is a billing arrangement that lets a business export surplus solar electricity to the IESCO grid and receive credit against future electricity bills, instead of that excess generation going to waste. It requires an IESCO-approved bidirectional meter and connection, and the process from application to activation typically takes about 4-6 weeks when documentation is complete. For businesses, net metering makes it possible to size a system efficiently without worrying about generation that exceeds real-time consumption.
How net metering works for a business
During business hours, solar generation offsets consumption directly. On weekends, holidays, or any time generation outpaces the business's real-time load, the surplus flows out to the grid through the bidirectional meter, and that exported amount is credited against the business's account. When the business draws more than it generates — such as at night — it draws normally from the grid, with net billing reflecting the balance between what was exported and what was consumed.
Requirements and process
- NEPRA and IESCO approval: required for any grid-tied installation; Tripower is NEPRA certified and IESCO-approved for net metering.
- Documentation: includes the NOC and IESCO application paperwork, handled as part of Tripower's standard installation process.
- Bidirectional meter installation: installed and commissioned as part of the connection process.
- Timeline: roughly 4-6 weeks from application to activation when paperwork is complete, though this can vary.

Why net metering matters for commercial ROI
Without net metering, any solar generation beyond immediate consumption would be wasted, forcing businesses to undersize systems conservatively to avoid overproduction. With net metering in place, businesses can size systems closer to their full consumption potential, improving overall payback and making the roughly 3-5 year payback period achievable across a wider range of commercial use cases. See our guide on the ROI of commercial solar for how this factors into overall returns.
Frequently Asked Questions
Does every commercial solar installation need net metering?
Net metering is optional but strongly recommended for grid-tied systems, since it ensures surplus generation isn't wasted and improves overall system economics.
Who handles the net metering application for a business?
Tripower manages the NOC and IESCO documentation and application as part of its standard installation process, from paperwork through commissioning and meter activation.
What happens if net metering approval is delayed?
The solar system can typically still generate and offset on-site consumption while approval is pending, though formal grid export and billing credit only begin once the net metering connection is activated.
