JinkoSolar and what a record shipping year does not tell you

JinkoSolar supplies us n-type TOPCon modules in the Tiger Neo family, in the volumes that keep a large array from waiting on stock. It shipped more modules than any other maker in 2025 and still reported a full-year net loss, and its place on the BloombergNEF Tier 1 list has been interrupted once. On a commercial roof it sits in the value part of our line-up, where the binding number is cost per watt across a wide, regular plane.

The largest module supplier by volume, specified where roof area is plentiful and the case turns on cost per watt rather than watts per square metre.

JinkoSolar is the module maker most likely to be in a UK distributor’s warehouse on the day you ask. That is worth something real on a scheme above 50 kWp, where the panels are usually the one item on the programme that ought never to be the reason a roof sits empty.

It is also the maker whose headline figures are the easiest to misread, so this page spends its first chapters on the reading rather than on the range.

01 Bankability

The biggest shipper is not automatically the safest counterparty

Volume and financeability are two different readings, and JinkoSolar is the clearest case on this site of them pulling apart. It shipped 86.8 GW of modules in 2025, taking the global first place by sales for the seventh time and passing 400 GW cumulative by the first quarter of 2026. In the same year it reported a full-year net loss, because module prices fell across the whole industry rather than because demand for its product did.

There is a second thing a diligence team should have in front of it. The ticker most people look up, JKS on the NYSE, belongs to a Cayman-incorporated holding company. The operating subsidiary, Jiangxi Jinko, is listed separately on the Shanghai STAR Market under 688223, and that is the side of the group a module warranty is administered from. Neither structure is unusual for a Chinese manufacturer of this size, but a funder who has only read the NYSE filing has not read the manufacturer.

BloombergNEF Tier 1 lists JinkoSolar for Q1 2026. We re-verify the listing for the exact module before contract.

02 The range

JinkoSolar supplies solar modules

Solar modules

Volume n-type TOPCon modules, 72 and 78 cell

The panel we reach for on a long, uninterrupted roof run where the array is limited by budget rather than by area. The large 78-cell format covers more square metres per fixing and per connection, which takes cost out of the mounting and the labour rather than out of the module.

  • Tiger Neo 72HL4-BDV
  • Tiger Neo 78HL4-BDV
  • Tiger Neo 3.0
  • Cell architecture: N-type TOPCon
  • Format: 72-cell and 78-cell large format
  • Build: Bifacial, dual-glass on the BDV codes

We hold no JinkoSolar datasheet in our own registry, so the power bin, the efficiency figure and the warranty years are read off the current sheet for the exact code rather than quoted from a brochure.

Datasheet figures only. We publish no price, and the exact model is confirmed against the design and the current datasheet before order.

04 The 2025 accounts

Record volume, negative result

Both numbers are true of the same twelve months, which is why we put them next to each other rather than choosing the flattering one.

  • 86.8 GW Modules shipped More than any other manufacturer
  • Net loss Full-year 2025 result Industry-wide price pressure, not insolvency
  • Seventh time Global first by sales A volume ranking, not a credit rating
05 The cell

Tiger Neo, and why TOPCon suits a roof that gets hot The technology reason we are content to put a value module on a twenty-five-year asset.

JinkoSolar reaches the UK commercial market mainly through the Tiger Neo family, built on n-type TOPCon cells. TOPCon places a thin tunnel-oxide passivating layer behind the cell. Two consequences matter on a flat commercial roof: light-induced degradation is lower, so less of the first year’s output is given away, and the temperature coefficient is flatter than the older p-type PERC cell it replaced.

The temperature point is the practical one. A dark membrane roof in July runs a long way above the 25 degrees Celsius the nameplate is measured at, and that is also the part of the year when a distribution shed or a chilled store is drawing hardest. A flatter coefficient means more of the modelled yield actually arrives in the hours the building is paying most for its electricity.

The dual-glass bifacial codes add rear-side response, which is worth having on a light single-ply membrane and worth very little on a dark one. We model it rather than assume it, and the assumption is set out in the yield model rather than left in the sales figure. Our comparison of TOPCon, HJT and PERC sets the cell types side by side.

06 Diligence

Two ways a JinkoSolar specification goes wrong

Both of these have been seen in real tender documents, and both are avoidable at the specification stage rather than at the claim stage.

Mistake one

Specifying the family, not the code

Tiger Neo spans several formats, power bins and datasheet revisions, and a document that names only the family does not describe a panel. The bin governs the string design, the dead load and the row spacing.

  • Name the full code, including the format and the bin
  • Record the datasheet revision the design was built against
  • Re-read the sheet if the order slips into a new production run

We fix the code in the written specification, not in the covering email.

Mistake two

Treating the ticker as the counterparty

A diligence pack that quotes the NYSE holding company has described the group but not the entity behind the module. The operating arm is listed separately in Shanghai, and that is where a warranty claim is administered.

  • Identify the supplying entity and the distributor of record
  • Check who the warranty is written by, not who is listed
  • Keep the group structure in the pack rather than one ticker

Neither point argues against specifying JinkoSolar. Both argue for describing it accurately in the documents that will outlive the sale.

JinkoSolar is a mainstream choice rather than a specialist one, and the honest version of that is a shorter list of places it wins than a value brand usually gets written up with.

07 Honest placement

Where we specify JinkoSolar, and where we do not

Specify

Where it fits

  • Wide, regular roof planes where the array is capped by budget and not by square metres.
  • Programmes that cannot carry a stock risk, because mainstream Tiger Neo codes are held deep in UK distribution.
  • Funders who will accept a current listing once they have been told plainly that it has been interrupted.
Specify something else

Where it does not

  • A funding pack that asks for an unbroken Tier 1 record. JinkoSolar cannot evidence one, and we will not word around it.
  • Roofs where the limit is area rather than cost, where a back-contact module puts more generation into the same footprint.
  • A specification frozen months ahead of the order, because the power bin and the datasheet revision move with the production run.
08 FAQ

JinkoSolar on a commercial roof: common questions

No, and this is the one question worth asking about this maker specifically. JinkoSolar was removed in the second quarter of 2024 over a minor unresolved legal matter and was later reinstated. It is on the list for Q1 2026. We describe the current listing with its quarter named, never a continuous record, and we re-verify the live quarter for your exact module code before contract.

It is a fact that belongs in your pack rather than a reason to rule the maker out. The loss came with the highest shipment volume in the industry and reflects module prices falling across the sector. A listing measures financeability and industry acceptance; it does not certify financial strength, which is exactly why we state the result rather than let the listing stand in for it. We confirm the manufacturer’s current standing as part of the diligence before specifying.

A Tiger Neo code from the 72-cell or 78-cell family, chosen after the roof is surveyed and the layout is fixed. We do not publish a wattage, an efficiency percentage or a dimension here, because we hold no JinkoSolar datasheet in our own registry and will not print a figure we cannot stand behind. The code, the bin and the warranty years are read from the current manufacturer sheet and written into your specification.

We publish no per-panel or per-watt figure. On a commercial roof the module is a modest share of an installed cost that is set by the roof type, the fixing method, the inverter selection and the grid connection works. JinkoSolar generally lands in the value part of our line-up rather than the premium end, which changes the shape of the figure rather than the way it is built. The bands are explained in our commercial solar cost guide.

Rarely, and that is the practical argument for this maker. Mainstream Tiger Neo codes are held in depth by UK distribution, so the pacing items on a scheme above 50 kWp are the structural survey, the design sign-off and the G99 connection rather than the panels. We confirm the live stock position and the delivery date for the exact code at proposal stage.

No. MCS is a domestic scheme and a commercial array of this size sits outside it, so the assurance is engineered rather than badged: design and installation to BS 7671, commissioning and verification to IEC 62446-1, a G99 connection agreed with the network operator, CDM 2015 duties through the works and a structural survey behind the layout. RVTC Installations Ltd holds the contract. Our quality without MCS guide sets out the full stack.
