HPBC is back-contact N-type. It is “latest Longi” in September 2026.
Back-contact cells hide the busbars. HPBC (LONGi) and ABC (AIKO) are the 2026 flagship talk: 640–650 W, pretty face, anti-shade/anti-dust slides.

Key takeaways
- You still wash.
- X10 watts: 640–650 W — HPBC 2.0.
- AIKO ABC: ~640 W — Fewer PK dealers.
- Wash: Still required — Marketing is not water.
- Pay HPBC when the roof is tight or dirty and the lot is documented.
Advantages and disadvantages
- You still wash. You still need 14 SWG iron. You still need a flash report. The premium is for a bit of shade/dust behaviour and watts in a 2278 mm frame — not for skipping engineering.
- You can photograph serials, protocol, and a shed test.
- Hi-MO 5 called HPBC
- No flash on X10
- Premium with 16 SWG iron
What it is
You still wash. You still need 14 SWG iron. You still need a flash report. The premium is for a bit of shade/dust behaviour and watts in a 2278 mm frame — not for skipping engineering.
In Pakistan 2026
If the dealer cannot show X10 vs X7 on the datasheet, you are buying a word. Hi-MO 5/6 is not HPBC. “Longi 550 HPBC” is a lie.
How we spec it
Pay HPBC when the roof is tight or dirty and the lot is documented. Otherwise volume TOPCon is the adult buy. Handling and clamps are the same family as other 645 W glass.
Numbers you can actually use
Street ranges, not a quotation. Confirm the carton the week you book.
| Thing | 2026 number | How to use it |
|---|---|---|
| X10 watts | 640–650 W | HPBC 2.0 |
| AIKO ABC | ~640 W | Fewer PK dealers |
| Wash | Still required | Marketing is not water |
Worked example — Quetta
Take a 6 kW-class hybrid in Quetta (QESCO, ~5.8 PSH). 10 × 645 W is 6.45 kW DC. Derated yield ≈ 6.45 × 5.8 × 0.78 ≈ 29.2 kWh on a clean day — then high PSH and cold January Voc. This page (HPBC / ABC) is the piece of that plant people skip on WhatsApp. If your quote cannot survive this Quetta sentence, it will not survive May. Open the calculator with city set to Quetta, and the lookup map for a stocking dealer — not a green-meter SKU.
Keywords this lesson actually answers
People land here asking hpbc 2.0, aiko abc, himo x10. The honest 2026 answers still collapse to: N-type plates with flash, IP65 hybrid with GRID vs LOAD, 51.2 V LFP on CAN, 14 SWG, XLPO, derate 0.78, and net-billing at ~Rs 11 export if you file with QESCO. Everything else on this page is how not to get robbed while buying those things.

FAQ — HPBC / ABC
Is HPBC bifacial?
Many are. Rear gain needs bright high iron, not a sooty flush mount.
Does ABC stop shade loss?
It reduces some mismatch. A chimney still wins. Do not skip string layout.
LONGi or AIKO?
Flash + importer invoice + iron. Fewer AIKO boards in small towns.
