What it is
Skip leftover PERC on new hybrids. TOPCon volume. HPBC/HJT when the paper and the roof say so. This page is the long version of that sentence, with a sequence you can hand to an electrician.
In Pakistan 2026
Pakistan 2026 context: net-billing (SRO 251) for new files, hybrid+LFP default for shed houses, 645 W N-type plates, 14 SWG, XLPO, CAN closed-loop. Anything that still sounds like 1:1 net-metering and 540 W PERC is leftover talk.
How we spec it
Follow the steps in order. Photograph each step. If a shop skips a step, that skip is the quote discount.
Numbers you can actually use
Street ranges, not a quotation. Confirm the carton the week you book.
| Thing | 2026 number | How to use it |
|---|---|---|
| Default plate | 645 W N-type | Calculator |
| Default house box | 6 kW IP65 hybrid | LOAD vs GRID |
| Default pack | 5.12 kWh LFP CAN | 90% DoD |
| Derate | 0.78 | Heat and dust |
Do this in order
- Ask the cell name.
- Ask flash.
- Compare NOCT on hot roofs.
- Match iron to frame weight.
- Do not mix generations on one MPPT.
What “done” looks like
Owner app login, serial folder, earth reading, protocol photograph, and — if hybrid — a shed test with the fridge still running. If any of those are missing, you are still in the shop, even if you paid.
Related calculators
Load, plates, battery, wires, iron, net-billing. Use them before you argue with a package price. This how-to (perc vs topcon vs hpbc vs hjt) is the human sequence around those numbers.
Worked example — Faisalabad
Take a 8 kW-class hybrid in Faisalabad (FESCO, ~5.1 PSH). 13 × 645 W is 8.38 kW DC. Derated yield ≈ 8.38 × 5.1 × 0.78 ≈ 33.3 kWh on a clean day — then mills, 3-phase, and tube-well neighbours. This page (PERC vs TOPCon vs HPBC vs HJT) is the piece of that plant people skip on WhatsApp. If your quote cannot survive this Faisalabad sentence, it will not survive May. Open the calculator with city set to Faisalabad, and the lookup map for a stocking dealer — not a green-meter SKU.
Keywords this lesson actually answers
People land here asking perc vs topcon vs hpbc vs hjt, solar guide pakistan. 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 FESCO. Everything else on this page is how not to get robbed while buying those things.

FAQ — PERC vs TOPCon vs HPBC vs HJT
Can I skip a step if it turned on?

No. Carton wins. This is the Pakistan-shaped checklist around it.
Do I need a DISCO file for this?
Only if you export. The how-to still applies.
Where do I find shops?
Lookup map. Still use this checklist on them.
