Title, NOC, cable route, who washes. Politics before iron. Apartments and plazas. The plates do not care, the roof does. 645 W glass is a sail. 14 SWG still applies.

Key takeaways
- Mounting system, leak path, walkway, cable entry, and who owns the waterproofing are the spec — not the watt sticker.
- Plates: 645 W N-type — Same cells.
- Iron: 14 SWG or specified Al — Not 16 SWG.
- Leak: Design it — Year-2.
- Write the mount type on the quote.
What it is
Mounting system, leak path, walkway, cable entry, and who owns the waterproofing are the spec — not the watt sticker.
In Pakistan 2026
Apartments and plazas. Net-billing still wants roof title. A beautiful array on a disputed society roof is a dead file.
How we spec it
Write the mount type on the quote. Earth the iron. Re-torque. Coastal: aluminium. Photograph flashing and glands at handover.
Numbers you can actually use
Street ranges, not a quotation. Confirm the carton the week you book.
| Thing | 2026 number | How to use it |
|---|---|---|
| Plates | 645 W N-type | Same cells |
| Iron | 14 SWG or specified Al | Not 16 SWG |
| Leak | Design it | Year-2 |
| Title | Needed to file | NOC if tenant |
Handover photos
Feet, flashing, glands, earth bond, clamp zones. If the shop only photographed the selfie wall, you do not have a roof file.
Worked example — Karachi
Take a 6 kW-class hybrid in Karachi (K-Electric, ~5.4 PSH). 10 × 645 W is 6.45 kW DC. Derated yield ≈ 6.45 × 5.4 × 0.78 ≈ 27.2 kWh on a clean day — then salt air and aluminium iron. This page (Shared / society roof) is the piece of that plant people skip on WhatsApp. If your quote cannot survive this Karachi sentence, it will not survive May. Open the calculator with city set to Karachi, and the lookup map for a stocking dealer — not a green-meter SKU.

FAQ — Shared / society roof
Can I skip penetrations?
Ballast where wind and load allow. Not every roof.
Who is liable for leaks?
Write it. Waterproofing vendor + installer.
Ground mount DISCO?
Still a file if you export. Theft is extra.
Elevated bifacial?
Rear light helps. Wind loads rise. Iron must match.

guideApartment / roof rights solar
You need the roof on paper. Net-billing needs title.
guideRCC / concrete roof
Chemical anchors or properly designed feet. Waterproofing warranty. Walkways.
guideMetal / standing-seam roof
Clamp to seams where the system allows. Do not drill every rib like a barn video.
