Why LONGi is Pakistan's Most Trusted Solar Panel Brand
LONGi Solar (隆基绿能) was founded in 2000 and has grown to become the world's largest monocrystalline solar manufacturer. As of 2025, LONGi produces over 60 GW of solar panels annually — more than any other manufacturer. Their HPBC (Hybrid Passivated Back Contact) cell technology delivers among the highest efficiencies available in mass production.
For Pakistan's climate — high ambient temperatures, frequent dust storms, and intense summer radiation — LONGi panels are particularly well-suited. Their low temperature coefficient means they lose less power in Faisalabad's summer heat compared to lower-grade alternatives.

Why LONGi Matters in Pakistan's Climate
Low Temperature Coefficient
At -0.29%/°C, the HiMo X10 loses far less power in Faisalabad's 45°C+ summers than conventional panels (-0.40%/°C). On a 50°C panel surface (common in July), you recover 3.3% more power vs. average panels — significant over 25 years.
LID and LeTID Resistance
Light-Induced Degradation (LID) and Light and Elevated Temperature Induced Degradation (LeTID) cause hidden power losses in the first year of operation. LONGi's HPBC technology is inherently resistant to both, giving you the rated power from day one.
Dust Tolerance
LONGi panels feature an anti-reflective coated, hydrophobic glass surface. In Faisalabad's dusty conditions, this reduces soiling losses and allows rain to clean the panel surface more effectively than flat-glass alternatives.
Genuine Warranty Enforcement
As an authorised flagship dealer, Saigal Solar can submit warranty claims directly to LONGi's Pakistan representative. Panels from unauthorised dealers may have voided warranties regardless of what the seller claims.
How to Verify Your LONGi Panels Are Genuine
Check the Serial Number Label
Each genuine LONGi panel has a barcode label with a unique serial number on the back of the panel and on the junction box. The label should clearly show the LONGi brand, model number, and wattage.
Verify via LONGi's Online Portal
Scan the QR code on the panel or enter the serial number on LONGi's official product authentication page. Genuine panels will show manufacturing date, specifications, and warranty status.
Check the Warranty Card
Genuine LONGi panels from authorised dealers include a warranty card with the dealer stamp and installation date. Saigal Solar provides this for every order.
Request Import Clearance Documentation
For large orders, ask for the Bill of Lading or import clearance certificate confirming the panels were imported through official channels and cleared NEECA inspection.
