## Complete Guide to Solar Net Metering in Pakistan
**Net Metering** allows solar energy system owners to export excess electricity generated during peak daylight hours back to the main power grid. Your DISCO credits your monthly bill for every unit (kWh) exported.

Key Requirements for Net Metering Approval
1. **Three-Phase Connection**: Your property must have an active 3-phase commercial or domestic DISCO connection. 2. **Inverter Certification**: Solar inverters must be NEPRA-approved (Category V grid-tied with anti-islanding protection). 3. **Green Meter (Bi-Directional Meter)**: Installed by DISCO to record import (consumed) vs export (fed to grid) units. 4. **Sanctioned Load Matching**: Installed solar capacity generally should not exceed your sanctioned load.
