Actual / theoretical. Engineer word for derate honesty. In a 2026 Pakistani hybrid quote this word should show up with a number, not as decoration.

Key takeaways

What it is

Houses can watch app kWh vs calculator.

In Pakistan 2026

On Hall Road and Saddar, performance ratio is either printed on a carton or it is a vibe. Net-billing, 645 W N-type, 51.2 V LFP and 14 SWG are the default stack. If a shop cannot place performance ratio inside that stack, they are selling 2019.

How we spec it

When we spec performance ratio, we write it on the BOM, photograph it at handover, and refuse to hide it inside a package name. Use the calculators for kW, kWh, mm² and iron. Use lookup for a dealer who stocks boards.

Numbers you can actually use

Street ranges, not a quotation. Confirm the carton the week you book.

Performance ratio on a real BOM

If performance ratio belongs on your job, it gets a SKU or a measured number. If it only belongs on a brochure, you are being entertained. Pakistan 2026 is a bad year to be entertained: export is cheap and leftover PERC is still being sold as latest.

How this ties to load-shedding

On-grid dies in shed on purpose (anti-islanding). Hybrid LOAD + LFP is the house product. Place performance ratio on the correct side of that split or you will “own solar” and still light candles.

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 (Performance ratio) 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 performance ratio, performance ratio solar. 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 — Performance ratio

Do I need to memorise Performance ratio?

You need to see it on the quote and the carton. This page is the translation.

Does this change after net-billing?

Self-use and LFP matter more. The definition of the term did not magically change.

Is this in the calculator?

If it is kW, kWh, mm², iron, or city PSH, yes. If it is a DISCO paper, see the DISCO guides.
