If you are planning rooftop solar in Pakistan this year, one detail decides whether your application is approved or thrown out: the **AEDB-approved panel and inverter list**. In 2026, only equipment that appears on this list clears DISCO inspection for net billing. Buy the wrong inverter — however powerful — and your file gets rejected at the technical stage, costing you months and, in some cases, the price of a second inverter.

This guide explains exactly how the AEDB-approved list works in 2026, how to check it before you pay, the mistakes that get applications rejected, and why hybrid inverters now dominate almost every new installation.

What the AEDB-approved list actually is

The Alternative Energy Development Board (AEDB) is the federal body that vets solar equipment for grid-connected use in Pakistan. Under NEPRA's framework, your Distribution Company (LESCO, K-Electric, IESCO, MEPCO and the rest) will only sanction a grid-tied system if the inverter — and increasingly the panel brand — sits on the approved equipment list.

The important shift in 2026 is the policy itself. NEPRA has replaced classic net *metering* with a **net billing** model under the Prosumer Regulations, 2026. Instead of one-for-one unit adjustment, your exported units are now bought at a lower rate — the buyback for new consumers has been cut to roughly **Rs 8–11 per unit**, while you still import from the grid at Rs 40–50 per unit. Existing net-metering consumers are grandfathered on their older terms (around Rs 25 per unit) for the remainder of their contract, which has shrunk from 7 years to 5 for new applicants.

The equipment rule did not relax when the tariff changed. If your inverter is not AEDB-approved, no buyback rate applies at all — your file simply does not clear inspection.

How to check the AEDB-approved list before you buy

Never take a vendor's word for it. Verify approval in writing before any payment:

  • **Ask for the model number in writing**, then match it against your DISCO's current approved-inverter list — not last year's PDF. Each DISCO maintains its own list, and a model approved by LESCO is not automatically approved by K-Electric.
  • **Confirm the installer is AEDB-certified** as an "Active Installer." Only a registered installer can legally submit your single-line diagram (SLD) and installation certificate.
  • **Contact AEDB directly** by helpline or email if a specific model or import batch is unclear — approvals are issued per model and per batch, so a look-alike unit can be unapproved.
  • **Check anti-islanding certification** (UL 1741 or IEC 62116). This safety standard is non-negotiable for grid tie-in and is checked at inspection.

A genuine, current approval reference on the AEDB list is your single best protection against a rejected file. Our team at Best Solar Company PK cross-checks every model against the live DISCO list before quoting — see our net metering application guide for the full document checklist.

Why applications get rejected at DISCO inspection

Most rejections have nothing to do with the quality of your panels. They come from avoidable paperwork and equipment mismatches:

  • **Non-approved inverter model** — the number-one cause. The unit works fine but is not on the list.
  • **CNIC and electricity-account name mismatch** — the meter must be in the applicant's name.
  • **Inverter capacity exceeding sanctioned load** — net billing is typically allowed on systems with an adequate sanctioned load and (for most DISCOs) a three-phase connection; a common threshold is a **5 kW** minimum.
  • **Missing safety gear** — no DC/AC surge protection devices or inadequate earthing/grounding.
  • **Transformer saturation** — if your local transformer has already absorbed too much solar export from neighbours, your file is delayed until a grid upgrade, regardless of perfect paperwork.
  • **Unregistered vendor** — applications filed by non-AEDB installers are refused outright.

Why hybrid inverters now dominate

Three years ago most homes fitted a simple on-grid (string) inverter. In 2026, **hybrid inverters** have taken over new installations — and the net billing rules are the main reason.

Under net billing, the units you export earn only Rs 8–11, but the units you *avoid buying* save you Rs 40–50. That gap makes it far smarter to **store cheap solar energy and use it yourself** than to sell it back. A hybrid inverter charges a battery during the day and discharges it in the evening peak, so you consume your own generation instead of exporting it at a loss.

Hybrids also ride through Pakistan's frequent load-shedding — an on-grid inverter shuts off the instant the grid drops, while a hybrid keeps your home powered from the battery. Most modern hybrid models on the AEDB list already carry the required anti-islanding protection, which keeps your application clean.

| Factor | On-grid (string) | Hybrid inverter | |---|---|---| | Battery support | No | Yes | | Works in load-shedding | No | Yes | | Best under net billing | Weak (export at low rate) | Strong (self-consume) | | Typical 5 kW price (PKR) | 180,000–320,000 | 450,000–850,000 | | AEDB approval available | Yes | Yes (wide range) |

The higher upfront cost of a hybrid is increasingly justified because self-consumption, not export, is now where the savings live. For a deeper cost breakdown, read our solar system price guide.

What a compliant 2026 net-billing setup costs

Beyond panels and inverter, budget for the process itself. A bidirectional smart meter runs about **Rs 18,500**, and total net-billing connection costs — processing fees, meter and installation labour — typically land between **Rs 100,000 and Rs 200,000**. Expect **30 to 90 days** from application to commissioning, sometimes 3–4 months depending on your DISCO and how clean your documents are.

Frequently Asked Questions

**Is net metering still available in Pakistan in 2026?** Classic net metering has been replaced by net billing under NEPRA's Prosumer Regulations, 2026 for new applicants. Existing net-metering consumers keep their original terms and older buyback rate until their contract ends.

**How do I know if my inverter is AEDB-approved?** Get the exact model number in writing and match it against your DISCO's current approved-inverter list, or confirm directly with AEDB. Never rely on a shop's verbal assurance — approvals are issued per model and per batch.

**Will a non-approved inverter still pass DISCO inspection?** No. If the inverter is not on the approved list, the technical inspection fails and your application is rejected, no matter how good the equipment is. You would have to replace it to proceed.

**Why should I choose a hybrid inverter over an on-grid one?** Under net billing, exported units earn only Rs 8–11 while imported units cost Rs 40–50. A hybrid stores your solar in a battery so you self-consume it, saves far more, and keeps running during load-shedding.

The bottom line

In 2026, the AEDB-approved list is the gatekeeper for every net billing application in Pakistan. Verify your panel and inverter models against your DISCO's live list before you pay, insist on an AEDB-certified installer, and lean toward a hybrid inverter so the new net billing economics work in your favour. Get those three right and your DISCO inspection becomes a formality — not a gamble. **Talk to Best Solar Company PK for a free, list-verified quote before you commit.**
