Solar cell suppliers for US module makers

A mixed bin of cells shows up as a weak module later.

Cells decide what your line can make, and a batch with loose efficiency bins or hidden cracks costs you twice: once in yield, again in returns. We check solar cell suppliers on certification, manufacturing capability and trade history before they can quote, and we can fund up to 100% of the order.

  • Suppliers checked before they quote
  • Mono PERC, TOPCon and HJT
  • M10 and G12 formats

Tell us what cells your line needs

Technology, format, efficiency bin and monthly volume are enough to start. A procurement specialist replies within one working day.

No cost to talk. No credit check for the first conversation.

Before you order cells

Three conversations every module line should have with its cell supplier

What changes when solar cell suppliers are checked before they quote.

You

“The last shipment's efficiency bins were all over the place.”

VyaparCred

Then the bin belongs in the requirement, with the tolerance you can live with. Mixed bins mean mismatch losses in every module you build, so specify the efficiency bin and color sorting, and every quote answers to them.

And the only solar cell suppliers able to bid on it are ones that have passed our checks on certification, manufacturing capability and trade history.

You

“Will G12 cells even run on our stringer?”

VyaparCred

That's the first thing to settle. M10 cells use a 182mm wafer and G12 cells a 210mm wafer, and your stringer and module layout decide which your line can take.

Put the format in the spec, and suppliers quote only what your line can actually use.

M10 vs G12, compared

You

“Cells arrive cracked, and we only find out on the line.”

VyaparCred

Ask for EL images of the batch before it ships, and write a breakage tolerance into the requirement, so inspection happens before the money's gone rather than on your stringer.

Documents, inspection and milestones are tracked on the order in one place.

Fund the batch before it ships

Cell buyer's checklist

What to check before you buy solar cells in bulk

Six checks that keep your module line fed with cells it can actually use. We handle the first pair before any maker can bid; the other four go in your requirement.

Line up checked cell makers

  1. Certification

    We check this

    Checked before the supplier can quote. Confirm on the quote that it covers the cell type and format you're ordering, so finished modules have a clean path through IEC testing.

  2. A real cell line and a shipping record

    We check this

    Manufacturing capability and trade history, checked before any quote reaches you.

  3. Format that fits your line

    In your spec

    M10 (182mm) or G12 (210mm), matched to your stringer and module layout before you order.

  4. Efficiency bin and color sorting

    In your spec

    Tight bins and consistent color, so modules don't lose output to mismatch or fail on appearance.

  5. EL images and breakage tolerance

    Ask for this

    Electroluminescence images of the batch and an agreed breakage tolerance, before the balance is paid.

  6. Landed cost per watt

    In every quote

    A cheap cell that ships expensively isn't cheap. Every bid shows the delivered cost, next to its rivals.

Cell technologies

PERC, TOPCon or HJT cells: what you can source

Every mainstream cell technology in M10 and G12 formats, from solar cell suppliers checked before they quote.

Proven and economical

Mono PERC

The mainstream cell for cost-sensitive module lines.

  • M10
  • G12

Higher efficiency

TOPCon

TOPCon cells deliver more output than standard PERC, and they're now the default on many new lines.

  • M10
  • G12

Top efficiency

HJT

High efficiency and low temperature losses, for premium module lines.

  • M10
  • G12

Financing

Keep the line fed without draining cash

Two ways module makers fund cell orders.

When the cell maker wants a deposit before production

Pre-shipment financing

Cover up to 100% of a confirmed cell order, paid straight to the maker, with a decision on funding inside 48 hours.

How pre-shipment financing works

When you buy cells every month

Supply chain finance

Monthly cell supply on 90-day terms for you, with the cell maker paid at T+2 through a vendor payment program.

FAQ

Solar cell supplier questions, answered

How do I find reliable solar cell suppliers?
Begin with a shortlist that's already been vetted. Solar cell suppliers on VyaparCred pass checks on certification, manufacturing capability and trade history before they're allowed to bid, so every cell quote you compare comes from a proven maker.
What's the difference between M10 and G12 solar cells?
M10 cells use a 182mm wafer and G12 cells a larger 210mm wafer. G12 fits fewer, larger cells per module and suits higher-power formats, while M10 remains the mainstream size.
Can I buy TOPCon and HJT cells in bulk?
Yes. Put the technology, format, efficiency bin and monthly volume in one requirement, and cell makers who can meet it quote against it.
What should I check on a cell batch before paying the balance?
The efficiency bin and color sorting against your spec, EL images of the batch, and the breakage tolerance you agreed. Documents, inspection and milestones are tracked on the order.
Can you finance a cell order?
Yes. A single confirmed batch can be funded through pre-shipment financing at up to 100% of its value, while standing monthly cell supply fits a vendor payment program better.

Keep your line running on cells that fit it.

Technology, format and volume gets you checked solar cell suppliers, landed-cost quotes and a funding number. No cost to talk.
