1. The 6-Point Solar Panel Selection Checklist
Follow this checklist when buying panels in Pakistan:
1. Tier-1 Brand Status: Choose globally recognized manufacturers (Jinko, Longi, Canadian Solar, JA Solar, Trina Solar).
2. Cell Chemistry: Insist on N-Type TOPCon over older P-Type PERC for superior heat tolerance.
3. Dual-Glass Bifacial Construction: Provides superior mechanical hail resistance and zero backsheet peeling.
4. Embedded Sub-Glass Barcode: Confirm barcode is laminated inside the glass, not glued on top.
5. Temperature Coefficient: Target values between -0.28%/°C and -0.30%/°C.
6. Authorized Importer Warranty: Verify that warranty is backed by an established Pakistani distributor.
2. How to Avoid Second-Hand or Refurbished Panels
Wholesale markets occasionally re-label decommissioned commercial modules as new. Check frame screw holes for prior clamping scratches and verify that junction box diode seals are intact.
