My brother bought a Longi Hi-MO 7 620W Bifacial Solar Panel yesterday from the local market in Sahiwal, and I found that its latest price is 23,000 rupees today. The per-watt price of the Longi Hi-MO 7 620W Bifacial Solar Panel is 43 rupees for A-Grade in Pakistan.
The Longi Hi-MO 7 620W Bifacial Solar Panel is the most popular and trending because of its highest potential rate 25% to generate huge electricity, as well as a longer life span of more than 25 years with little care in Pakistan.
The combination of N-Type HPDC technology, low temperature coefficient, bifacial rear generation, and a 30-year performance warranty makes this one of the smartest long-term investments for Pakistani buyers. It will payback our investment in just 3 years at a high rate of electricity costs in Pakistan.
The 620W variant specifically is excellent for large commercial projects and solar farms like solar tube wells because they carry small space but generate more electricity. According to my brother, it generates 600 watts of solar energy at a time and 3000 watts or 3 units in a day.
My Personal Experience: I installed a set of Longi Hi-MO 7 panels on my rooftop in Okara last year, and the experience completely changed how I look at solar energy in Pakistan in 2026.
What Is the Longi Hi-MO 7 620W Bifacial Solar Panel?
The Longi Hi-MO 7 is not just another solar panel sitting on a shelf. It is one of the most talked-about modules in Pakistan’s solar market right now, and for good reason.
The 620W variant (model: LR8-66HGD-620M) is the high-capacity version of the Hi-MO 7 series. It is built for utility-scale power plants, large commercial rooftops, and serious residential setups where you need maximum output from limited roof space.
Key Technology Behind the Panel
The panel runs on N-Type HPDC (High-Performance Dual Cell) bifacial technology. In simple terms, HPDC splits each solar cell into two halves, which reduces internal resistance and boosts energy output, especially in partial shade or high-heat conditions. Pakistan has plenty of both, so this matters.
What really impressed me was the busbar-free black front design. No metal lines crossing the surface means more sunlight hits the actual cell. The result is a sleeker look and better performance at the same time.

| Longi Hi-MO 7 – 620W | PKR 42–43/watt | PKR 26,040 – 27,280 |
Note: Prices vary by city, dealer, and market demand. Always get at least three quotes before buying.
Why the 620W Costs a Little More
The 620W model is a commercial/utility-grade product. It uses a slightly larger frame (2382mm × 1134mm × 30mm) and delivers a module efficiency of 25%, which is among the highest available in Pakistan today. You pay a small premium, but you get significantly more power per panel installed.
My personal experience: When I was comparing options, a dealer in Lahore told me, “The 620W is mostly bought by commercial buyers and solar farms.
Homeowners usually go for 575W or 580W because the solar panel is lighter and easier to mount on a standard residential roof.”

Why the Temperature Coefficient Matters in Pakistan
I want to highlight one specification that most buyers ignore completely: the -0.28%/°C temperature coefficient.
Pakistan’s summers are brutal. Rooftop temperatures in Lahore, Multan, and Okara regularly cross 60°C–65°C in June and July.
Standard solar panels can lose 7–9% of their rated output at these temperatures. The Hi-MO 7 loses only around 5.5% even at 45°C above its rated temperature.
Over a full Pakistani summer, this small difference adds up to hundreds of extra kilowatt-hours, which means real savings on your electricity bill.
I noticed this myself. On the hottest days in July, my Hi-MO 7 panels were still producing noticeably more than my neighbor’s older PERC panels of the same wattage.
He was actually surprised when I showed him the comparison on my monitoring app.
The Bifacial Advantage on Pakistani Rooftops
There, we will also discuss the Bifacial Advantage on Pakistani Rooftops in Pakistan, and here we will also discuss as follows.
What “Bifacial” Actually Means
Bifacial panels generate electricity from both the front and the rear of the panel. The rear captures light reflected off the surface below, white-painted rooftops, concrete, and even light-colored gravel.
The Hi-MO 7 has an 80% bifaciality rate, which means the rear can produce up to 80% of what the front generates from reflected light. In practical terms, this can add 5–15% extra energy output at no extra cost.
My Personal Experience with Rear-Side Generation
My roof is painted white, which is typical in Punjab. After monitoring for three months, I noticed my solar panels were consistently outperforming their rated output on clear days.
My solar installer confirmed this was partly the rear-side generation at work. It is not dramatic, but it is free extra electricity, and over 25 years, it adds up.
Where to Buy Longi Hi-MO 7 620W in Pakistan
Authorized Dealers and Trusted Sources
One of the biggest risks in Pakistan’s solar market right now is counterfeit panels. Low-quality copies are being sold with Longi branding, and they perform terribly within 2–3 years.
Here is my advice based on personal experience:
Always buy from an authorized dealer or a well-known distributor. Ask for the QR code verification on the panel and scan it through LONGi’s official verification system before accepting delivery.
Major cities where genuine stock is readily available:
- Lahore – Several established dealers in Anarkali, Shahrah-e-Quaid-e-Azam, and DHA
- Karachi – Industrial areas in Korangi and SITE
- Islamabad/Rawalpindi – Dealers near Raja Bazaar and Blue Area
- Multan, Faisalabad, Okara – Smaller distributors, so verify extra carefully
Online Platforms
Platforms like solarpricehub.com and a few others do deliver Longi panels nationwide with cash-on-delivery options.
I ordered a sample panel this way to check quality before buying in bulk. Just make sure any online seller provides a proper invoice and warranty card.
Longi Hi-MO 7 vs Other Solar Panels in Pakistan (2026 Comparison)
| Brand & Model | Price/Watt | Efficiency | Temperature Coefficient |
|---|---|---|---|
| Longi Hi-MO 7 | PKR 38–43 | ~22.8–23% | -0.28%/°C |
| Jinko Tiger Neo (N-Type) | PKR 38–43 | ~22.5–23% | -0.30%/°C |
| Canadian Solar TOPCon | PKR 40–44 | ~22–23% | -0.29%/°C |
| JA Solar DeepBlue 4.0 | PKR 29–31 | ~21–22% | -0.30%/°C |
The Longi Hi-MO 7 has a slight but meaningful edge in temperature coefficient over Jinko Tiger Neo. In a hot country like Pakistan, that edge matters every single summer.
How Many Panels Do You Need for Your Home?
This is a question I get from neighbors regularly. Here is a simple breakdown:
For a Typical Pakistani Home
- 3–5 kW system (medium house, 5–8 ACs): 6–9 panels of 580W
- 8–10 kW system (large house): 14–18 panels of 580W
- For 620W panels, you need slightly fewer panels for the same system size — useful if roof space is limited
My own 6 kW system uses 10 solar panels of the 580W variant. If I had gone with 620W panels, I could have done the same job with 9 solar panels and saved some mounting hardware cost.
Installation Costs to Budget For
The panel price is just one part of the total cost. When I installed my system, the full breakdown looked roughly like this:
- Solar panels – the highest cost (varies by wattage and quantity)
- Inverter – PKR 80,000–200,000+, depending on brand and capacity
- Mounting structure – PKR 15,000–40,000 depending on roof type
- Wiring, breakers, meters – PKR 20,000–50,000
- Installation labor – PKR 20,000–50,000 depending on system size and location
Always get a written quotation with warranties included. A good installer will honor the panel manufacturer’s warranty and handle any claims process on your behalf.
Warranty and Long-Term Reliability
- 12-year product warranty (materials and workmanship)
- 30-year linear performance warranty — guaranteeing at least 87.4% output at year 30
With an annual degradation rate of only 0.40%, this panel is genuinely built to last. That is one of the lowest degradation rates available in the market today.
Compare that to cheaper no-name panels that degrade at 0.7–1.0% per year. After 25 years, the difference in output is enormous.
Should You Buy the 620W or the 580W?
Buy the 620W if:
- You are installing a commercial or industrial system
- You have limited roof space and need maximum watts per panel
- You are building a ground-mounted system where the larger, heavier panel is not a problem
Stick with 575W–585W if:
- You have a standard residential rooftop
- You want an easier installation (lighter panels, same technology)
- Your installer recommends it based on your inverter’s string configuration
Personally, I went with the 580W for my home and have no regrets. The 620W is a great panel; it is just designed for a different scale of project.
