LONGi Panel Verification to Check a Real Hi-MO

Key Takeaways
- LONGi's official module authenticity page asks for the product barcode, described as a string of numbers on the front or back of the module (July 2026).
- LONGi launched One Module One Code on 16 March 2022, attaching a unique anti-counterfeiting QR code to each module nameplate that returns type, certification, electrical parameters and warranty.
- LONGi told ARY News its panel manufacturing business has been "directly impacted" by counterfeiting in Pakistan and that consumer awareness remains low.
- Pakistani price sheets quoted LONGi at Rs 43.50 per watt documented (24 July 2026), Rs 38 to Rs 39.50 per watt general market (25 July 2026), and Rs 32 to Rs 40 per watt on non-documents lists (25 July 2026).
- Hi-MO 7 610W is listed at 22.60% efficiency, -0.280%/degC temperature coefficient, 12-year product warranty and 30-year power warranty (July 2026).
Why is LONGi the most faked panel brand in Pakistan?
Because it is the most bought. LONGi is the world's largest module manufacturer by shipment volume, and Pakistani market coverage in 2026 describes the 575-610W Hi-MO 7 as the best-selling model in the country. Counterfeiters do not chase obscure brands. They chase the sticker a customer walks in and asks for by name.
LONGi itself is on record about this. Speaking to ARY News, a LONGi official said the company's solar panel manufacturing business has been "directly impacted" by counterfeit stock in Pakistan, noted that "consumer awareness remains low", and pointed to a 157-point checklist and a unique verification process as the company's response. Pakistani market reporting in the same piece describes rejected B-grade and C-grade panels being relabelled with well-known brand stickers, and a large volume of substandard modules entering through border routes such as Chaman and Torkham.
The commercial mechanics are simple. A no-name 585W module and a genuine Hi-MO 7 look nearly identical from three feet away on a rooftop. The difference is a laminated barcode, a database record, and about Rs 6,000 per panel. That gap is the entire business model of the people you are trying to avoid.
LONGi ran its largest Pakistan summit in Lahore on 29 April 2026, launching Hi-MO One commercial storage, the OneBank 3.1MW/6.25MWh package and a solar pumping system. A brand investing at that level in a market is also a brand whose name is worth stealing in that market.
Where is the barcode on a LONGi Hi-MO module?
LONGi's own module authenticity page states the product barcode is "a string of numbers on the front or back of the module". In practice on Hi-MO series modules you will find the identifier in two places. It is laminated under the front glass, and it is on the rear nameplate label alongside the electrical data.
Since March 2022, LONGi has also run One Module One Code. LONGi describes it as attaching "a specific anti-counterfeiting QR code" to module nameplates, and says scanning it gives customers access to module type and level, product certification, electrical parameters, product specification and warranty. That is a meaningfully richer response than a plain yes/no authenticity check, and it is the reason a QR scan on a genuine recent Hi-MO should return a data page rather than a bare confirmation.
The physical test comes first, before any phone comes out. Run a fingernail across the front barcode. On a genuine laminated module it is smooth and sealed beneath the glass, because it was placed between the encapsulant and the front glass before the panel was pressed. Pakistani buying guides put this plainly. A barcode you can scratch off with a nail is a sticker, not a barcode, and the panel under that sticker is different from what is claimed.

How do you run LONGi panel verification step by step?
- Choose the modules yourself from different layers of the pallet, including one from the middle of the stack. Never accept a list of serials handed to you on paper.
- Nail-test the front barcode on each chosen panel. Anything that lifts, catches or peels ends the inspection there.
- Photograph the front barcode and the rear nameplate with the frame edge visible, so each image is tied to a specific physical panel.
- Type longi.com into your browser yourself and go to the module authenticity page. Do not arrive via a search result, a QR code printed on the dealer's own paperwork, or a WhatsApp link.
- Enter the product barcode as printed. Confusing 0 with O and 1 with I is the most common cause of a false failure.
- If the module carries a One Module One Code QR, scan it separately and confirm the returned model, electrical parameters and warranty match the panel and the invoice in front of you.
- Repeat on the delivered pallet, not only on the showroom sample. Showing a genuine sample and delivering something else is the standard method here.
LONGi lists a support hotline of (+86) 4008 601012 on its authenticity page. That is a China number, which tells you something useful. The manufacturer's verification chain does not run through your dealer, and your dealer cannot influence its answer.
What LONGi Hi-MO specifications promise

Item | Hi-MO 7 (610W) | Hi-MO X6 Max Explorer |
|---|---|---|
Module efficiency | 22.60% | Not published on the same page |
Temperature coefficient of Pmax | -0.280%/degC | -0.28%/degC |
Product warranty | 12 years | 15 years |
Power warranty | 30 years | 25 years, ending 89.4% |
Annual degradation | up to 0.4% | Year 1 at 99% |
Figures as of July 2026.
Two things are worth saying out loud. First, the product warranty and the power warranty are different promises, and the shorter one matters more. A junction box failure, a cracked backsheet or a delaminated laminate in year seven is a product warranty claim, and those are the failures that happen. The 30-year number only pays if you can prove sustained underperformance against a curve, which requires instruments, roof access and documentation most homeowners never assemble.
Second, warranty terms vary by product line and by market. LONGi's own pages show a 12-year product warranty on Hi-MO 7 and 15 years on Hi-MO X6 Max Explorer. Anyone quoting you a single flat LONGi warranty figure without naming the exact model has not read the datasheet for the panel they are selling you.
What does the July 2026 LONGi price spread tell you?
Three Pakistani price sheets published within two days of each other quoted LONGi very differently, and that spread is the most honest counterfeiting indicator in the market.
- solarpanelpriceinpakistan.pk, 24 July 2026. Hi-MO 7 585W bifacial and 610W double glass both at Rs 43.50 per watt, described as Tier-1 documented.
- pakistansolarmarket.com, 25 July 2026: "The price of Longi solar panels varies between Rs. 38 and Rs. 39.5 per watt".
- solarpanelmarket.pk, 25 July 2026. Rs 32 to Rs 40 per watt, with a Hi-MO 7 610W double glass listed at Rs 33 per watt.
On a 610W module, Rs 43.50 per watt is about Rs 26,500 (July 2026) and Rs 33 per watt is about Rs 20,100 (July 2026). That Rs 6,400 per panel is not a bargaining win. It is the price of the paperwork. This includes a GST-paid import, a commercial invoice in your name, a packing list carrying your serial numbers, and an original warranty card rather than a photocopy.
For a 10 kW rooftop of roughly 17 modules, choosing the cheaper column saves around Rs 109,000 (July 2026) and removes your ability to make a claim on any of them. Whether that trade is sensible depends entirely on how long you intend to own the system. On a five-year horizon with a tolerance for risk, maybe. On a system you expect to outlive your car loan, no.
What are the fake LONGi tells to check on site?

- Peelable front barcode. The fastest disqualifier. Genuine identifiers are laminated under the glass.
- Front barcode and rear nameplate disagree. Relabelling usually replaces one copy, not both.
- QR code that leads anywhere other than LONGi's own domain. Scan it, then read the URL before you read the page.
- A nameplate wattage that does not match the module's physical size or cell count. A 540W-class laminate relabelled as 585W is a common Pakistani fraud.
- Cell colour drift within one panel. Genuine A-grade cells are uniform; mottled or mismatched cells indicate sorted rejects.
- Uneven busbars or solder splash on the cell surface, and hand-smeared silicone at the junction box or frame corners.
- No serial-matched flash test report. Ask for the sheet that lists your specific serial numbers, not a generic model datasheet.
- A quoted rate far below the documented band with no stated reason. Pakistani wholesale guides flag Rs 5 to Rs 8 per watt below market as suspicious, and the July 2026 LONGi spread runs wider than that.
One more thing, because nobody selling you panels will say it. Verifying the serial protects you from a fake. It does not protect you from a genuine module that was never meant for this market and therefore has no local service channel. Ask the dealer, in writing on the invoice, who honours the warranty inside Pakistan and at what address. If the answer is vague, treat the panel as unwarranted regardless of what the portal says.
