I have noticed that the Longi 545 Watt Solar Panel is the most popular and in demand in Pakistan, especially Lahore, Faisalabad, Multan, and Karachi, because of its long life as well as performance to generate electricity.
The Longi 545 Watt Solar Panel price is 16,500 to 19,800 for the A-Garde single glass mono ficial solar panel in Lahore, Karachi, and Faisalabad, and this huge price differnce because of dealer margin and transport. The latest solar panel prices totally depend on brand, size, technology and availability in Pakistan.
The Longi 545 Watt Solar Panel price per-watt is very cheap, which is about 30 to 36 rupees, also depending on area and availability in Pakistan. The solar panel prices in Karachi are the cheapest because of the very low shipping cost and availability.
The Longi 545 Watt Solar Panel has an efficiency rate 22% and a life of 12 years for product warranty and 25 years with 85% performace warrant in Pakistan.
My personal experience today: There is a 3 to 4 rupees per-watt decrease in Pakistan for all brands of solar panels.
What Is the Longi 545 Watt Solar Panel?
The Longi 545W is part of Longi Solar’s Hi-Mo 5 series, a generation of panels that brought monocrystalline PERC half-cut cell technology into mainstream affordability.
It is also informative news that Longi (officially LONGi Green Energy Technology Co., Ltd.) was founded in 2000 and has since grown into the world’s largest solar panel manufacturer by shipment volume.
The company holds a permanent Tier-1 classification, which means it meets the financial, manufacturing, and quality benchmarks that separate serious solar brands from fly-by-night importers.
The 545W model specifically uses M10 wafer technology — a slightly larger silicon wafer size (182mm) that extracts more power per cell without dramatically increasing the physical size of the panel.
Longi 545 Watt Solar Panel Price in Pakistan Today
The latest Longi 545-watt solar panel price in Pakistan falls within the following range, depending on the variant, supplier, and city:
| Variant | Price Per Panel (PKR) | Price Per Watt (PKR) |

| Hi-Mo 5 Single Glass (Mono PERC) | PKR 16,000 – 18,500 | PKR 29 – 34/W |
| Hi-Mo 5 Double Glass (Bifacial N-Type) | PKR 17,500 – 20,500 | PKR 32 – 38/W |
| Hi-Mo 5 (Wholesale, 10+ panels) | PKR 15,000 – 16,500 | PKR 27 – 30/W |
These prices are sourced from market rates across Lahore, Karachi, Rawalpindi, and Peshawar. Prices vary due to transport costs, dealer margins, and daily fluctuations in the USD/PKR exchange rate, since most panels are imported and priced against the dollar.
City-Wise Price Comparison
There, we will discuss City-Wise Price Comparison of Longi 545 Watt Solar Panel in Pakistan, like Lahore, Karachi, Rawalpindi, Multan, and Faisalabad.
| City | Approximate Price Per Panel |
|---|---|
| Lahore (Hall Road Market) | PKR 16,000 – 18,000 |
| Karachi (Saddar / Burns Road) | PKR 16,500 – 19,000 |
| Rawalpindi / Islamabad | PKR 16,200 – 18,500 |
| Multan | PKR 15,800 – 17,500 |
| Peshawar | PKR 16,000 – 18,200 |
| Faisalabad | PKR 15,500 – 17,000 |
Buyers in Lahore and Karachi generally have the widest selection of authorized dealers, which means more price competition and better odds of finding genuine stock. In smaller cities, margins may be slightly higher due to fewer suppliers.
Why Does the Price Change Frequently?
Exchange Rate Fluctuations — Pakistan imports the vast majority of its solar panels from China. Since these transactions happen in US dollars, a rupee devaluation directly increases the local price. When the dollar rises, panel prices typically follow within days.
Import Duties and GST — The federal government periodically revises import duties and sales tax on solar equipment. Any new policy announcement can shift prices overnight.
Seasonal Demand — Solar installations spike before summer (March–May) as everyone tries to get panels on the roof before peak electricity demand. This seasonal surge increases prices by 5–10% at the retail level.
Batch Quality and Certifications — Authorized A-grade panels certified under AEDB standards cost more than uncertified or B-grade panels. Always confirm the grade before purchasing.

Single Glass vs Double Glass — Which Should You Choose?
The Longi 545W comes in two structural variants that Pakistani buyers frequently confuse:
The single glass version uses a standard tempered front glass with a polymer backsheet. It is lighter, slightly cheaper, and perfectly adequate for rooftop residential setups where moisture and mechanical stress are not extreme concerns. Most Pakistani homes do well with this version.
The double glass (bifacial) variant replaces the polymer backsheet with a second sheet of tempered glass. This makes the panel heavier and more expensive, but it offers two important advantages.
First, the bifacial design generates electricity from both the front and rear sides of the panel — particularly useful on white or light-colored rooftops where reflected sunlight can boost output by 5–15%.
Second, double glass construction offers significantly better resistance to humidity, salt mist, and mechanical load — important for coastal cities like Karachi and for rooftop environments that experience heavy dust and monsoon rains.
For a typical Pakistani home in Lahore, Faisalabad, or Multan, the single glass 545W panel is the more practical and economical choice.
For commercial flat rooftops, agricultural pump systems, or coastal installations, the double glass bifacial version delivers better long-term returns.
How Much Power Does a Longi 545W Panel Actually Generate in Pakistan?
This is the question that matters most to anyone calculating their electricity savings. The rated output of 545 watts refers to performance under Standard Test Conditions (STC), specifically 1000 W/m² irradiance, 25°C cell temperature, and 1.5 air mass.
Real-world conditions in Pakistan are rarely this clean, but Pakistan is fortunate to have one of the highest solar irradiance rates in the region.
Daily Units (kWh) by City
Using average peak sun hours (PSH) for each major Pakistani city:
| City | Avg. Peak Sun Hours | Daily Output (Single Panel) | Monthly Output (Single Panel) |
|---|---|---|---|
| Karachi | 5.5 – 6.0 hrs | 2.8 – 3.0 kWh | 84 – 90 kWh |
| Lahore | 4.8 – 5.5 hrs | 2.6 – 2.9 kWh | 78 – 87 kWh |
| Multan | 5.5 – 6.2 hrs | 2.9 – 3.3 kWh | 87 – 99 kWh |
| Islamabad | 4.5 – 5.2 hrs | 2.5 – 2.8 kWh | 75 – 84 kWh |
| Peshawar | 4.8 – 5.5 hrs | 2.5 – 2.9 kWh | 75 – 87 kWh |
| Quetta | 6.0 – 6.5 hrs | 3.1 – 3.4 kWh | 93 – 102 kWh |
On average, a single Longi 545W panel generates approximately 2.2 to 2.7 units (kWh) per day across Pakistan’s diverse climate zones. Multan and Quetta, sitting in the sunny belt, squeeze the most out of every panel.
Real Temperature Performance
One of the most overlooked issues in Pakistani solar installations is heat-related power loss. During summer, a panel’s surface can reach 60°C–70°C on a black rooftop. At this temperature, efficiency drops from the rated figure.
The Longi 545W’s temperature coefficient of -0.35%/°C means that for every degree above 25°C, output drops by 0.35%. At 65°C (a realistic rooftop temperature in Lahore in June), that is a 14% drop in output.
This sounds alarming, but it is better than most budget panels, which commonly carry coefficients of -0.40% to -0.45%/°C, resulting in even steeper summer losses.
How Many Longi 545W Panels Do You Need?
One of the most practical questions every buyer asks is: how many panels will I actually need? The answer depends on your system size, which in turn depends on your monthly electricity consumption.
Panel Count by System Size
| System Size | Panels Required | Ideal For |
|---|---|---|
| 3 kW | 5–6 panels | Small apartment, 2–3 fans, 1 AC, basic lighting |
| 5 kW | 9–10 panels | Medium home, 2 ACs, refrigerator, TV, lighting |
| 7 kW | 12–13 panels | Large home or small office, 3–4 ACs |
| 10 kW | 18–19 panels | Commercial shop, small factory floor |
| 15 kW | 27–28 panels | Mid-scale commercial or industrial setup |
A standard Pakistani household with a monthly consumption of 500–700 units typically needs a 5–7 kW system, meaning 9 to 13 panels of the 545W variant.
If you are aiming to fully offset your WAPDA bill through net metering, aim for a system that generates at least 110–120% of your average monthly consumption to account for cloudy days and seasonal variation.
Longi 545W and Net Metering in Pakistan
Net metering has transformed the financial math of going solar in Pakistan. Under NEPRA’s net metering policy, any excess electricity your panels generate during the day is exported to the grid and credited against your nighttime consumption. The Longi 545W is fully compatible with net metering in Pakistan.
What You Need for Net Metering
To register for net metering in Pakistan, your system must include a grid-tied or hybrid inverter approved by NEPRA, and your installer must be registered with the Alternative Energy Development Board (AEDB).
Longi panels are among the most commonly approved and specified panels in DISCO-registered net metering applications across LESCO, HESCO, PESCO, and other distribution companies.
The financial case is straightforward. A 10-panel Longi 545W system (approximately 5.45 kW) connected to the grid in Lahore can generate roughly 750–800 units per month.
If your home consumes 400 units per month, the surplus 350–400 units are credited by LESCO at the applicable per-unit rate.
Over 25 years, the life of the panel, this translates to a significant and compounding return on your investment.
Longi 545W vs Competing Panels in Pakistan
Pakistani buyers often compare the Longi 545W against other popular options. Here is how it stacks up:
Longi 545W vs Jinko 545W
Both are Tier-1 Chinese manufacturers with globally comparable build quality. Jinko panels in the same wattage range are often priced PKR 1–3 per watt cheaper than Longi, making them attractive for cost-sensitive buyers.
However, Longi has a marginal edge in temperature coefficient and degradation rate, which matters in Pakistan’s brutal summers. Both carry the same 12-year product warranty and 25-year output warranty.
Longi 545W vs Canadian Solar 545W
Canadian Solar panels are slightly premium-priced and well-suited to hybrid inverter setups. They perform comparably to Longi under Pakistani conditions but have a slightly narrower authorized dealer network.
Longi 545W vs Local/B-Grade Panels
This is where the comparison becomes critical. Locally assembled or B-grade panels may cost 30–40% less per panel, but they carry risks that outweigh the savings:
higher degradation rates (1.5–2% per year versus Longi’s 0.7%), shorter lifespan (5–10 years versus 25 years), and absent or worthless warranty claims.
Over 10 years, a system built on cheap panels costs more in replacements and lost generation than a properly priced Tier-1 system from day one.
What Factors Affect the Longi 545W Price in Pakistan?
There are also many Factors Affect the Longi 545W Price in Pakistan and here we will discuss them one by one as follows.
Import Duties and Taxes
Pakistan periodically adjusts its solar import duty policy. As of 2026, Tier-1 solar panels are largely free of additional customs duties under the government’s renewable energy promotion policy, though GST applicability can vary based on system type and registration.
Always ask your dealer for a GST-inclusive vs. GST-exclusive price breakdown.
USD to PKR Exchange Rate
Because solar panels are priced in dollars at the import stage, a 10-rupee movement in the exchange rate can shift panel prices by PKR 1,500–2,000 per panel.
Authorized vs Unauthorized Dealers
Authorized LONGi distributors in Pakistan include Royal Solar Energy, Nanosun DMCC, and Power House Express.
Panels purchased through authorized channels come with original manufacturer warranty cards, traceable serial numbers, and AEDB-compatible documentation.
How to Verify an Original Longi 545W Panel in Pakistan
The market for counterfeit and mislabeled solar panels in Pakistan is, unfortunately, active. A B-grade panel may be relabeled as A-grade, or a lower-wattage panel may have its sticker swapped. Here is how to protect yourself:
Check the serial number printed on the panel’s back label. Every genuine LONGi panel can be verified on LONGI’s official website at longi.com using the serial number. If the number returns no results or an error, the panel is likely not genuine.
Examine the frame. Genuine LONGi panels have the LONGi logo embossed into the aluminum frame — not applied as a sticker. Press your nail gently on the logo area; if it peels or feels adhesive, walk away.
Ask for the original warranty card. Longi panels come with a physical warranty card that matches the panel’s serial number. If your dealer provides only a hand-written receipt or a dealer-issued warranty without the manufacturer’s card, that is a red flag.
Compare the per-watt price against current market rates. In May 2026, anything under PKR 27/watt for a genuine A-grade Longi 545W panel should be treated with skepticism. Genuine Tier-1 panels have a price floor below which an authentic product cannot be profitably supplied.
Request an IEC certification document from the dealer. Legitimate importers carry batch-level certification documents issued by testing labs.
