- LID: Lower than PERC — First-year fade.
- Temp coeff: ~−0.29 %/°C — Better than PERC.
- Accept TOPCon with flash and serials.
Advantages and disadvantages
- This is what most honest Pakistani lists still have in quantity. Jinko Tiger Neo 3.0 is the 630–650 W 20BB story. JA and Trina sit next to it. Hi-MO X7 is TOPCon; Hi-MO X10 is HPBC — do not confuse the two because both say Longi.
- You can photograph serials, protocol, and a shed test.
- X7 sold as X10

What it is
This is what most honest Pakistani lists still have in quantity. Jinko Tiger Neo 3.0 is the 630–650 W 20BB story. JA and Trina sit next to it. Hi-MO X7 is TOPCon; Hi-MO X10 is HPBC — do not confuse the two because both say Longi.
In Pakistan 2026
Street Rs/W for documented A-grade TOPCon in 2026 often lands high-30s to mid-40s depending on week and city. Cheaper than ABC/HJT, dearer than leftover PERC — correctly.
How we spec it
Accept TOPCon with flash and serials. Prefer 640–650 if the roof is tight. 575–590 is still a real module if the cell is N-type.
Numbers you can actually use
Street ranges, not a quotation. Confirm the carton the week you book.

Worked example — Islamabad
Take a 10 kW-class hybrid in Islamabad (IESCO, ~5.2 PSH). 16 × 645 W is 10.32 kW DC. Derated yield ≈ 10.32 × 5.2 × 0.78 ≈ 41.9 kWh on a clean day — then CDA/DHA NOCs stacked on the DISCO. This page (TOPCon) is the piece of that plant people skip on WhatsApp. If your quote cannot survive this Islamabad sentence, it will not survive May. Open the calculator with city set to Islamabad, and the lookup map for a stocking dealer — not a green-meter SKU.
Keywords this lesson actually answers
People land here asking topcon panel, tiger neo, vertex n. 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 IESCO. Everything else on this page is how not to get robbed while buying those things.

FAQ — TOPCon
TOPCon or HPBC?
HPBC/ABC if you pay for anti-shade/dust and the flash is real. Otherwise TOPCon is the workhorse.
Is Tiger Neo TOPCon?
Yes, N-type TOPCon. Neo 3.0 is the 2026 plate, not 2022 leftover.
Glass-glass TOPCon?
Some bifacial dual-glass. Heavier. Check iron SWG.
