Layout Analysis: Will 9 Panels Fit?
| Measurement | Value | Status |
|---|
| Roof Width | 12.00 ft (3658mm) | Reference |
| 3 Panels (portrait) | 3 x 4.27 = 12.81ft | Exceeds ~10in |
| L3 Stand Frame | 10.83ft (3300mm) | Fits (7in/side) |
| Panels overhang stand ~6.5in each side (standard in Pakistan) |
| Roof Length | 39.00 ft | Reference |
| 1 Panel Length | 7.82 ft | Fits easily |
| Remaining | 31+ ft free | Expansion space |
Verdict: Yes, 9 Panels CAN Fit
- Width is TIGHT: L3 stand frame (10.83ft) fits in 12ft with 7in margin per side. 720W panels (1303mm wide) overhang ~6.5in each side. Standard practice but tight.
- Length VERY comfortable: Panels use ~7.8ft of 39ft. 31+ ft free for expansion.
- Must use portrait orientation: 4.27ft wide x 3 = 12.81ft (tight). Landscape impossible on 12ft width.
- North-facing + no shade = ideal: Perfect for Pakistan latitude. 15-degree tilt appropriate.
- Future expansion: Room for up to 24 panels (8 L3 stands) along remaining 31ft.
Important: 720W panels at 1303mm width exceed L3 stand's nominal 1000mm per-panel slot. Verify with supplier that L3 variant supports 1303mm panels. Newer stands from Zaksun, Soluna, Comfort Solar are designed for this.
Recommended Layout
3 L3 stands side by side across 12ft width, each holding 3 panels in portrait, tilted 15 degrees north. Positioned at north end of roof.
