Since NEPRA's Prosumer Regulations 2026 replaced net metering with net billing, choosing the wrong solar company in Pakistan costs more than it used to. This guide shows you how to establish your own savings baseline first, verify AEDB certification, compare vendor quotes on equal terms, and spot the tactics that separate serious installers from resellers.
Choosing a solar company in Pakistan used to be relatively forgiving. Under the old net metering rules, every unit you exported to the grid was swapped one-for-one against a unit you imported, so even an oversized or mediocre system still produced a decent return. The policy did most of the work.
That is no longer the case. In February 2026, NEPRA replaced the 2015 net metering framework with the Prosumer Regulations 2026, moving new solar connections onto a net billing model. Exported and imported units are no longer treated as equal, and the buyback rate for surplus power was cut sharply — reported figures have ranged from around Rs 8 to Rs 11 per unit against a previous rate in the region of Rs 25 to 27. Consumers who already held valid agreements before the change were treated separately under a subsequent amendment.
The practical effect is that system design now matters far more than it did, and the company you hire is the one making those design decisions. A vendor who sizes your system to maximise export is now optimising for the least valuable kilowatt-hour you produce. This guide shows you how to build your own savings baseline before you talk to anyone, how to verify that a company is legitimate, and how to compare quotes so you are judging value rather than sticker price.
Policy in this area is moving quickly. Buyback rates, licensing fees and grandfathering rules have all changed within 2026, and figures reported in the press have not always agreed. Confirm the current rate and terms directly with your DISCO before you sign anything, and treat any number in a sales presentation as a claim to be verified.
Step 1: Establish your own savings baseline before you call anyone
This is the single most valuable thing you can do, and almost nobody does it. If you walk into a sales conversation with no independent estimate, the vendor's number becomes the only number in the room — and you have no basis on which to challenge it.
You need four inputs, and all of them come off your own electricity bill:
Your monthly units consumed, ideally for all twelve months rather than one. Summer air conditioning in Karachi, Lahore or Multan can double or triple winter consumption, and a system sized on a January bill will be badly undersized.
Your effective per-unit cost. Do not use the headline slab rate. Divide your total bill — including fuel charge adjustments, quarterly adjustments, taxes and surcharges — by the units consumed. In Pakistan this all-in figure is frequently far higher than the tariff people quote, and it is the number solar actually replaces.
Your daytime versus night-time usage split. Under net billing this has become the most important input in the entire calculation, and it is explained in the next section.
Your available roof area and its orientation. This sets the ceiling on system size regardless of what you would like to install.
Run these through the SolarBazaar savings calculator and the system size calculator to get an independent estimate of the system size you need and the savings it should produce. Then use the payback calculator to see the timeline.
You now have a defensible number. When a vendor proposes something significantly larger or promises savings significantly higher, you can ask exactly which assumption differs — and their answer will tell you a great deal about whether they are an engineering company or a sales operation.
If you are in Karachi, our breakdown of the K-Electric unit rate for 2026 covers how slab tariffs, FCA and taxes combine into the effective rate you should be using.
Step 2: Understand what net billing changed, because it changes the design
Under the old system, the grid functioned as a free battery. You exported in the afternoon while nobody was home and imported in the evening, and the two cancelled out. Sizing generously was rational.
Under net billing, the two no longer cancel. You buy from the grid at your full tariff and sell to it at a much lower fixed rate. That gap is the entire story.
The consequence is straightforward: a unit you consume yourself is worth roughly two to three times a unit you export. Every design decision should follow from that.
What it means in practice:
Oversizing for export no longer pays. A system sized well beyond your daytime load now dumps its surplus into the grid at the low buyback rate, and the extra capacity takes far longer to justify itself.
Load shifting is genuinely valuable. Running air conditioning, water pumps, washing machines and geysers during solar hours converts low-value export into high-value self-consumption at zero cost.
Hybrid inverters and battery storage have become considerably more attractive than they were under the old regime, because storing your surplus for evening use captures the full tariff rather than the buyback rate.
Your daytime consumption pattern is now a primary design input, not a footnote. A household where everyone is out during the day has a very different optimal system to one with someone home running an AC all afternoon.
Our detailed analysis of the 2026 net metering and net billing changes covers the policy in full. For whether storage makes sense in your case, see the solar battery guide and run your evening load through the battery size calculator.
A useful test of any vendor: ask them how the 2026 net billing change affects the system they are proposing. A company that gives you a specific answer about self-consumption and load timing understands the current market. A company that still talks about "selling electricity back to the grid" as the main benefit is working from an outdated script.
Step 3: Verify the company is actually certified
This is not optional paperwork. In Pakistan, only installers certified by the Alternative Energy Development Board can submit net metering or net billing applications to your DISCO. A file submitted by an uncertified company gets rejected — which means you have a solar system on your roof and no legal grid connection for it.
What to check, in order:
Ask for the AEDB certification number and its validity date. Certificates carry categories tied to system capacity and are valid for specific provinces and a specific expiry date. A legitimate company produces this immediately.
Verify it independently. Do not accept a photograph of a certificate. AEDB and PPIB publish lists of certified installers; cross-check the company name, certificate number, expiry date and the region it is valid for.
Check the expiry date specifically. Expired certification is a common problem, and companies do not always volunteer it.
Cross-check the Pakistan Engineering Council registration. AEDB-certified companies are required to hold valid PEC licences, and PEC maintains its own searchable database.
Confirm the certificate covers your province and your system size. A certificate valid for Punjab does not authorise work in Sindh, and capacity categories are limited.
If a company hesitates, offers excuses, or says certification is "not needed for your size," end the conversation. The DISCO will not accept their paperwork regardless of what they tell you.
Step 4: Compare quotes on equal terms
Get at least three written quotes. The mistake almost everyone makes is comparing the bottom-line rupee figures, which are rarely comparable at all — a cheaper quote is usually a smaller or lower-specified system rather than a better deal.
Normalise everything to cost per kilowatt
Divide the total quoted price by the system capacity in kW. This single number strips away the packaging and lets you compare like with like. Then investigate what explains the differences, because there will be legitimate reasons as well as illegitimate ones.
Demand an itemised quotation
A lump-sum price is a refusal to be accountable. A proper quotation lists, separately:
Panel make, exact model number, wattage and quantity
Inverter make, model, capacity, type — on-grid, hybrid or off-grid — and number of MPPTs
Mounting structure specification and material
DC and AC cable specification and lengths
Protection equipment: isolators, breakers, surge protection devices, earthing
Battery make, model, usable capacity and chemistry, if included
Net billing application handling, licensing fee, bidirectional meter cost and inspection coordination — stated as included or excluded
Installation labour, and whether scaffolding or crane access is extra
Warranty terms for each component, listed separately
Anything not written down is not included. This is the most common source of post-signing disputes in the Pakistani market.
Check the equipment independently
Vague terms like "Tier 1 panels" or "imported inverter" are not specifications. Get exact model numbers and verify them yourself. Compare panel efficiency, temperature coefficient and degradation warranty in the SolarBazaar panel database, and check inverter specifications in the inverter database.
Temperature coefficient deserves particular attention in Pakistan. Panels are rated at 25°C cell temperature, and rooftop cells in Lahore or Sukkur in June run far above that. A panel with a poor temperature coefficient loses meaningfully more output in exactly the months when your air conditioning load peaks — and that difference never appears in a headline wattage comparison.
For brand-level comparisons, see LONGi vs Jinko vs Canadian Solar in Pakistan, and for inverters, Huawei vs Sungrow. Our solar inverter guide explains which specifications actually matter and why the DC to AC ratio in a quote tells you whether the design was thought through.
Interrogate the savings claim
Every quote will include a projected saving. Ask three questions about it:
What generation figure was assumed per kilowatt? If the vendor's estimate is far above what the system size calculator suggests for your location, ask why.
What derate factor was applied? Real systems lose output to heat, dust, cable losses, inverter conversion and shading. Pakistan's dust levels in particular are significant, and soiling losses during a long dry season are among the highest anywhere. A projection with no derating overstates production substantially — our solar panel calculator guide explains the arithmetic.
What buyback rate and self-consumption ratio were assumed? This is where post-2026 projections most often break. A saving calculated using pre-February 2026 export economics will be far too optimistic for a new connection.
Step 5: Judge the things that only show up later
Equipment is easy to compare. Everything below is what determines whether you are satisfied in year five, and it is where cheap quotes usually turn out to be expensive.
Workmanship warranty. Separate from the manufacturer's product warranty, this covers the installer's own errors — roof penetrations, wiring faults, mounting failures. Five years is a reasonable floor. A company offering none is telling you something.
Who files the net billing application. A serious company handles the DISCO process in-house, including the single line diagram, inspection coordination and meter installation. Being handed a folder and told to visit the DISCO yourself is a meaningful cost you were not quoted.
After-sales response. Ask what happens if the inverter fails in year four. Who collects it, who pays shipping, is there a replacement while it is away, and does the brand have service presence in Pakistan? A warranty from a manufacturer with no local support is a logistics problem waiting to happen.
Monitoring ownership. The monitoring account must be registered in your name, not the installer's. Companies close and change hands; your data should not go with them.
Verifiable references. Ask for addresses of three installations completed at least two years ago, and actually call one. Recent references tell you the sales process worked. Older ones tell you the system did.
Company longevity and structure. A registered company with a physical office, a landline and traceable history is a different proposition to a WhatsApp number and a warehouse.
Red flags specific to the Pakistani market
Quotes given without a site visit. Nobody can design a system from a photograph and a bill total.
Large upfront payment demands. A deposit is normal. Most of the money should follow delivery and commissioning.
Prices that undercut the market substantially. The saving is coming from somewhere — usually refurbished or B-grade panels, undersized cable, a no-name inverter, or an intention to disappear after the deposit clears.
Refusal to name exact equipment models, or substituting different equipment at delivery. Photograph the serial numbers on arrival and check them against your contract before installation begins.
Savings projections still built on pre-2026 export economics. Either the company has not updated its material or it is knowingly overstating returns.
Pressure to sign immediately. Discounts that expire during a single visit are a technique, not a market condition.
No written contract, or one with no penalty for delay. Installation and approval timelines slip routinely; your contract should say what happens when they do.
Putting it together
The sequence matters. Establish your own baseline with the calculators first, so you enter every conversation with an independent number. Verify AEDB certification and PEC registration before you spend time on a quote. Collect three itemised quotations and normalise them to cost per kilowatt. Check the equipment specifications yourself rather than accepting brand adjectives. Then weigh the warranty terms, the after-sales structure and the references, because those are what you will actually be relying on.
Under net billing, the difference between a well-designed system matched to your consumption pattern and a generically oversized one is now measured in years of payback. The company you choose is the one making that call — which makes vendor selection, not equipment selection, the decision that matters most.
