LinkSolar is a China-based B2B supplier of custom & OEM solar panels, solar cells and mounting hardware. This page is for buyers who need solar cells cut to a size or current that a stock cell does not come in: a strip that fits a narrow enclosure, a segment count that hits a target voltage, or cells tabbed and ready to solder.
Two ways to buy. Standard cuts of the 125 mm and 166 mm back-contact (IBC) cells are listed online in packs of 10 or 20. Anything else — a strip width, a centre strip, pre-tabbed cells or a tiled kit — is quoted on your drawing. Quotes come back within 12 hours and the quote is free.
Standard cuts you can order online
The values below are typical figures at STC from the product listings. Cutting keeps the cell voltage and divides the current by the number of pieces.
125 mm back-contact IBC cell
| Cut | Size (mm, approx.) | Vmp | Imp | Pmp |
|---|---|---|---|---|
| Full cell | 125 × 125 | 0.625 V | 6.05 A | 3.78 W |
| Half cut | 125 × 62.5 | 0.625 V | 3.03 A | 1.89 W |
| 1/3 cut | 125 × 41.6 | 0.625 V | 2.02 A | 1.26 W |
| 1/6 cut | 125 × 20.8 | 0.625 V | 1.01 A | 0.63 W |
Packs of 10 or 20 cells. A 10-cell pack of full cells is US$46.60; prices for each cut are on the product page. Centre-strip options (1/3-width and 1/6-width) are listed in the variant selector when in stock.
166 mm back-contact IBC cell
| Cut | Size (mm, approx.) | Vmp | Imp | Pmp |
|---|---|---|---|---|
| Full cell | 166 × 166 | 0.60 V | 11.0 A | 6.60 W |
| Half cut | 166 × 83 | 0.60 V | 5.50 A | 3.30 W |
| 1/4 cut | 166 × 41 | 0.60 V | 2.75 A | 1.65 W |
| 1/8 cut | 166 × 20 | 0.60 V | 1.37 A | 0.82 W |
Packs of 10 or 20 cells; prices for each cut are on the product page. Centre-strip options (1/4-width and 1/8-width) are listed when in stock.
Choosing a cut: voltage from the count, current from the size
Every piece of a cut cell keeps the full-cell voltage, so the number of pieces in series sets your voltage and the cut size sets your current. With the 125 mm cell, 8 pieces in series give about 5.0 V typical (8 × 0.625 V); with the 166 mm cell, 9 pieces give about 5.4 V typical (9 × 0.60 V). Then pick the cut whose current fits your load and whose width fits the space you have.
If you are still working out the count, the guide to how many solar cells you need walks through the arithmetic, and the guide to soldering solar cells covers joining cut pieces.
Cut to order
When none of the listed cuts fits, send the size you need. Custom options listed for the 125 mm cell are below; for the 166 mm cell, ask with your drawing.
- Custom strip dimensions, for enclosures and surfaces where a standard 1/3 or 1/6 cut is the wrong width.
- Centre strips, where one trimmed strip is taken from the middle of each source cell and the side pieces are not supplied.
- Pre-tabbed or solder-ready cells, so cut pieces arrive ready to string. Tabbing parts are also sold separately, for example IBC dog-bone tabbing strips.
- Tiled cell kits for higher-voltage layouts.
Cells are cut by laser scoring and mechanical separation. Whether a particular outline can be cut is confirmed on your drawing before we quote.
What to send for a quote
| Send us | Why it matters |
|---|---|
| Cell format (125 mm or 166 mm), or the finished piece size in mm | Sets which source cell is used and how many pieces come from each cell |
| Target voltage and current at your string | Lets us check the cut and piece count against what you need |
| Quantity per order | Custom orders are quoted on your drawing and quantity |
| Bare, pre-tabbed or solder-ready | Changes the processing and the price |
Samples take 7–14 days and cost US$10–200 depending on the spec. The quote is free; samples are not. Every order is checked against the confirmed specification before it ships, and orders ship from China.
Other cells in stock
Back-contact cells are not the only option. We also list 182 × 183.75 mm N-type TOPCon cells, 158.75 × 79 mm PERC cells and smaller monocrystalline and polycrystalline formats in the solar cells collection.
Common questions
Is there a minimum order?
Standard cuts are sold online in packs of 10 or 20 cells. Custom cuts are quoted on your drawing and quantity.
Will my cut cells match the listed figures?
The listed values are typical reference figures at STC. Cutting loss, soldering, shading and your test setup can all change your results, so test a sample build before you commit to a production run.
Are these official SunPower or Maxeon cells?
No. The cells are de-branded, and LinkSolar is not affiliated with, endorsed by or authorized by SunPower or Maxeon. Cutting and processing are done to the confirmed specification before shipment.
What if I need a finished panel rather than loose cells?
That is a different order: see custom solar panels, where cells are laminated into a panel built to your dimensions by partner production lines.
