☀️ Trina 670W Solar Panel Price in Pakistan 2026 — Vertex Series
Complete guide to Trina 670W Vertex solar panels: current PKR prices, full specs, system sizing table (fewer panels needed), 210mm cell advantage, vs 550W comparison, and warranty.
📋 In this guide
1. Trina 670W Vertex — Overview
The Trina Solar Vertex TSM-DE21 670W uses Trina's 210mm large-cell technology. Compared to standard 182mm cells in most 550W panels, the 210mm format runs at lower current density — meaning less resistive heating per area and marginally better real-world output in Pakistan's extreme summer heat.
Core Pakistan appeal: fewer panels for the same power. A 10kW system needs 15× 670W panels vs 18–19× 550W — saving mounting hardware, roof penetrations, installation time and MC4 connectors. For commercial installations this translates to lower per-watt installation costs.
2. Trina 670W Price in Pakistan 2026
| Quantity | Price Per Panel | Rs. Per Watt | System |
|---|---|---|---|
| 1–5 panels | Rs. 42,000–55,000 | Rs. 63–82/W | Small top-up |
| 8 panels (~5kW) | Rs. 38,000–50,000 | Rs. 57–75/W | 5.4kW residential |
| 15 panels (~10kW) | Rs. 36,000–48,000 | Rs. 54–72/W | Large residential |
| 30+ panels (20kW+) | Rs. 34,000–44,000 | Rs. 51–66/W | Commercial bulk |
Lahore benchmark — other cities add 5–20%. Trina 670W typically carries a 5–15% per-watt premium over JA Solar 550W for the 210mm large-format benefit. Confirm stock from authorized distributor before committing — Trina 670W availability is city-dependent.

5. Trina 670W vs JA Solar 550W — Head-to-Head
| Factor | Trina 670W | JA Solar 550W |
|---|---|---|
| Price per watt | Rs. 51–82/W | Rs. 47–64/W ✅ cheaper |
| Panels for 10kW | 15 panels ✅ | 18–19 panels |
| Roof space saved | ~6m² less | Baseline |
| Inverter compatibility | Check Isc limit | Universal |
| Pakistan availability | Moderate | Best nationwide ✅ |
| Heat performance | -0.34%/°C (same P-Type) | Same |
| Best for | Commercial / space-constrained | Most residential buyers ✅ |
For most Pakistani residential buyers: JA Solar 550W is better value — lower per-watt, wider availability, universal compatibility. For commercial buyers needing to minimize panel count on a fixed roof: Trina 670W's fewer-panels advantage becomes financially meaningful at 20kW+ scale.
6. Heat Performance Pakistan Summer
| City | Operating Temp | Trina 670W Output | vs Rated |
|---|---|---|---|
| Lahore | 70°C | ~566W actual | 15.5% below STC |
| Multan | 75°C | ~554W actual | 17.3% below STC |
| DG Khan / Jacobabad | 80°C | ~541W actual | 19.3% below STC |
Trina 670W shares the standard P-Type temperature coefficient (-0.34%/°C) with JA Solar 550W — heat performance percentage is identical. Trina generates more absolute watts due to higher wattage base but loses the same fraction to heat. For extreme-heat buyers: N-Type TOPCon (LONGi Hi-MO 9, JA DeepBlue) with -0.27%/°C is the better choice regardless of panel size.

Frequently Asked Questions
Trina 670W Vertex: Rs. 34,000–55,000 per panel (Rs. 51–82/W). 8-panel 5kW system: Rs. 2,72,000–4,00,000. 15-panel 10kW system: Rs. 5,10,000–7,20,000. Lahore prices — other cities add 5–20%. Always compare in Rs./watt for fair comparison with other panel sizes.
For most Pakistani residential buyers: JA Solar 550W — lower per-watt cost (Rs. 47–64/W vs Rs. 51–82/W), wider availability, universal inverter compatibility, same heat performance. Trina 670W is better for: commercial systems minimizing panel count, space-constrained rooftops, buyers where fewer panels and MC4 connectors reduce system complexity. Heat performance is identical (both -0.34%/°C P-Type).
Most modern inverters handle Trina 670W: GoodWe EM, Sungrow SH, Solis RHI (larger models), Fronius GEN24 — all compatible. Key check: Isc is 18.11A — verify your inverter's max input current per MPPT is ≥18.5A. Some Growatt SPH and Inverex NitroX models have lower current limits — confirm with your installer before purchasing 670W panels for parallel string configurations.
15 panels × 670W = 10,050W DC — standard for a 10kW system. Saves 3–4 panels vs 550W (18–19 panels needed). Roof space: 15 panels × 2.6m² = ~39m². String configuration: 2 strings of 7–8 panels each (Voc per string: 38.3V × 8 = 306V — within most inverter MPPT ranges).
Yes — Trina Solar is Bloomberg Tier-1, one of the world's top 5 panel manufacturers. Trina Vertex 210mm series is newer technology with excellent global reliability data. Pakistan field performance feedback is positive. Buy from authorized Trina distributors and verify serial numbers at trinasolar.com after installation. Trina is less widely available than JA Solar nationwide — confirm stock before committing to a large order.

5kW on-grid with Trina 670W (8 panels) + GoodWe ES inverter + mounting + wiring + installation + net metering: Rs. 6–9 Lac (Lahore). Hybrid with 10kWh Pylontech battery: Rs. 11–16 Lac. Premium configuration with LONGi N-Type panels instead: Rs. 9–13 Lac on-grid. Trina 670W systems cost 5–15% more per kW than JA Solar 550W but require fewer panels — installation savings partially offset premium.
Same brand, very different specs: (1) Wattage: 670W vs 550W — 21.8% more power per panel. (2) Cell size: 210mm (670W) vs 182mm (550W) — affects Isc and string design. (3) Physical size: 670W is 12.8cm wider and longer — needs larger mounting space. (4) Price: 670W is 30–40% more per panel but only 5–15% more per watt. (5) Use case: 670W for commercial/space-constrained, 550W for standard residential. Same efficiency class (21.6% vs 21.3%) and same temperature coefficient (-0.34%/°C).
