PeakArray — N-Type TOPCon Solar Modules for Bulk Importers

Choose your format

Three formats, three different jobs

Pick by site condition, not by wattage. A 740 W module that cannot be carried onto a roof, or that overloads the inverter's MPPT input, costs you more than the extra watts earn you.

The part most suppliers skip

String and inverter fit

High-current modules quietly break designs. The number that matters is the inverter's maximum DC input current per MPPT, checked against module Isc — not Impp — multiplied by the number of parallel strings. Bifacial gain adds roughly another 10% on top. We check this against your inverter datasheet before quoting, not after delivery.

Format	Isc at STC	Isc + 10 % bifacial	One string	Two strings in parallel	Minimum per-MPPT rating
182R-66	15.95 A	17.53 A	17.5 A	35.1 A	36 A if double-stringed
210R-78	16.19 A	17.80 A	17.8 A	35.6 A	36 A if double-stringed
210-66	18.56 A	20.42 A	20.4 A	40.8 A	41 A if double-stringed

Read this before you copy a string design across formats. On an inverter limited to 30 A per MPPT, all three formats must be single-stringed once bifacial gain is counted — double-stringing overruns the input. That is workable, but it means more MPPT channels for the same DC size, so the cheapest module per watt can end up the more expensive system. The 210-66 format is the most demanding: it needs 40 A+ per MPPT to be double-stringed at all. Send us your inverter make and model and we will tell you which format actually costs you less installed.

Voc and cold-weather strings

210R-78 runs 58.21 V per module. On a 1100 V system, corrected to −10 °C, that caps the string at 16 modules. Tell us your site's design ambient temperature and we will send the string length, not a guess.

Snow and wind load

The formats pass 2400 Pa wind and 5400 Pa snow under IEC 61215. Those are test-pass values, not design allowances. On large formats in snow load above 1.5 kN/m², have a structural engineer verify purlin spacing — we will supply the load data sheet for it.

Handling and breakage

33.5 kg is a two-person carry. 37.5–38.5 kg on a 3.1–3.2 m² panel needs suction lifters on rooftops. Larger formats also carry a higher transit breakage rate, so we cap it contractually at ≤0.3% with free replacement of the excess.

The anti-dust frame is a real gain, not a brochure claim. On the 182R format, the raised edge profile reduces water-borne dirt accumulation at the short edge. Independent field results for this class of frame sit around 1–3% additional yield, and the value depends on rainfall, tilt and dust type. In arid, low-rainfall sites with soiling losses, that is the difference between a 5-year and a 6-year payback. It is also the reason we lead with this format in the Gulf.

Where these formats go

Three site types we quote for

The format you choose follows the site, not the budget. Below is what each segment actually looks like — so you can match the array to the ground under it.

Commercial and industrial rooftop array — **Commercial & industrial rooftop.** 1–5 MW typical, 1100 V strings, existing roof structure. The 182R format wins here: 33.5 kg is a two-person carry onto a roof.

Ground-mounted array in arid terrain — **Ground-mount in arid terrain.** Gulf, North Africa, Central Asia. Soiling and heat dominate the yield model — the anti-dust frame and the −0.30 %/°C coefficient both matter.

Off-grid solar and battery microgrid — **Off-grid and hybrid microgrid.** Telecom sites, remote settlements, mining camps. 1–20 MW with storage; the array size is set by the battery autonomy, not by roof area.

About these three images. They are illustrations of the site type — as is the banner image at the top of this page — not photographs of projects we delivered. We do not present rendered or stock imagery as our own track record. For real reference installations, ask us and we will send the project list with photographs and commissioning dates — subject to the end client's permission.

Component detail

Anti-dust frame (182R only). The raised short-edge profile lets rain carry soiling off the glass instead of trapping it at the bottom rail. Independent field data for this frame class sits at 1–3 % additional yield, depending on rainfall, tilt and dust type.

Close-up of N-type TOPCon cell surface — **N-type TOPCon cell surface.** Fine busbar spacing and the passivation stack are what separate a 23.50 % module from a 21 % one. This is the same cell platform across all three formats.

Where these are made

A TOPCon line you can audit

PeakArray is an export operation working with a TOPCon manufacturing base in Jinhua, Zhejiang, China. The producer of record on export documents is that facility. Your contract, your documents and your quality recourse sit with PeakArray — one point of contact.

Ground-mounted solar plant — Reference ground-mount installation by the manufacturing partner.

Commercial rooftop solar installation — Commercial rooftop array — the segment these formats are sized for.

Quality controls you can test

Two full EL (electroluminescence) inspections per module
Per-module serialisation, traceable for the module's life
AI inline inspection plus six QC gates
Batch COA and IV test report with every shipment

Certifications held

What we do not claim. These modules are not UL-listed, so we do not sell into the United States. There is no EPD, no WEEE registration and no IEC 62938 non-uniform snow-load certification at the time of writing — if your tender requires any of those, we will tell you plainly instead of bidding and losing your deposit. We also do not claim a bankability tier: this is a value play, not a project-finance play.

A note on destination duties. Solar is the most trade-remedied category in the world. Chinese-origin modules face layered measures in the United States (Section 301, AD/CVD and UFLPA), and India applies ALMM restrictions plus high duty. We do not ship to the United States in any form. For other destinations, confirm your own import duty before you compare our FOB price with a local quote — the landed number is the only one that matters.

Straight answers

Frequently asked

Are you the factory?

No. PeakArray is an export operation. We work with a TOPCon manufacturing base in Jinhua, Zhejiang. The producer of record on the export documents is that facility; your contract, your payment terms and your quality claim all sit with PeakArray.

We can arrange a live video walk-through of the cell and module lines, or an on-site audit scheduled with the factory. Ask and we will set it up.

Why is your price below the tier-one brands?

Because our partner is a second-tier brand selling on cost and flexibility rather than on brand premium. The realistic gap is in the 5–12% range on export pricing depending on volume and destination.

If the gap on your enquiry is under about 5%, we will usually tell you to buy the tier-one module instead. Below that threshold the bankability, longer product warranty and faster global service network are worth more than the difference.

Is this a bankable module?

Honestly: not for Western project finance. The manufacturer is not on the BNEF Tier 1 list and is not a PVEL Top Performer. If your tender names either of those, do not use us — you will be disqualified on eligibility.

For an owner-builder, a commercial rooftop, an off-grid mini-grid or a government small project where the money is your own, that distinction costs you nothing and the price gap is real.

Can you put our brand on the modules?

Private labelling is available, subject to the manufacturer's authorisation and a minimum quantity. Two things must be settled in writing first: who owns the trademark risk, and who carries the patent indemnity on the TOPCon cell process. We will not print labels before both are documented.

What documents do we get before paying?

Current datasheet with version number and effective date, IEC 61215 / 61730 / 61701 / 62716 certificates, ISO certificates, a sample batch COA, and the BOM list (glass thickness, frame wall, encapsulant type and weight, junction box and connector brand). We send these on request, free, before any deposit.

Ask for the datasheet version number specifically. The market has older sheets in circulation with superseded figures.

How do you handle transit breakage?

Contract cap of 0.3% including micro-cracks, assessed by EL sampling within 7 days of arrival. Excess is replaced free within 15 days at the supplier's freight cost. Loading and unloading are filmed container by container so the evidence exists before anyone argues.

Which format should we stock?

If you serve rooftops, dusty sites, or inverters with modest per-MPPT current headroom: the 182R-66 — it is the lightest to handle, the only one with the anti-dust edge, and the most forgiving on string design. If you serve large flat ground-mount where freight per watt dominates and your inverters accept 40 A+ per MPPT: the 210-66. If land is scarce and expensive: the 210R-78, but re-run the string voltage first.

Send us your inverter model and site conditions and we will make the call with you on a call, not from a spec sheet.

Do you sell to the United States?

No. No UL listing, and the combination of Section 301, AD/CVD and UFLPA makes it uneconomic and unwise. We also do not route through third countries to dodge those measures.
