LONGi HiMo X10 Scientist — 640~670W
N-TaiRay + HPBC 2.0 + 0BB (Zero Busbar) technology — no frontal gridlines, A+ anti-shading, prevents localised overheating. Up to 24.80% module efficiency (670W). Dual-glass construction, -0.26%/°C temperature coefficient — engineered for Pakistan's 45°C+ summers.
In Stock · High Bifaciality
LONGi Hi-MO 7 — LR8-66HGD 595~625W Bifacial
Advanced HPDC half-cell bifacial technology — 80±5% bifaciality captures rear reflected light for additional generation on light-coloured or elevated rooftops. 23.1% module efficiency. Excellent for large industrial rooftops and elevated ground mounts where rear irradiance is available.
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 flagship HiMo X10 Scientist uses N-TaiRay + HPBC 2.0 + 0BB technology (up to 24.80% efficiency), while the Hi-MO 7 uses HPDC half-cell bifacial technology — both among the highest-output panels 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 -0.26%/°C (Pmax), the HiMo X10 Scientist 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 over 3.5% more power vs. average panels — significant over 30 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.
Why X10 Beats TOPCon on Faisalabad Rooftops
Every rooftop in Faisalabad has some partial shading — water tanks, AC outdoor units, parapets, or a neighbour's boundary wall. This is where most solar panels silently lose money. The Hi-MO X10 Scientist is engineered specifically to keep producing even under these conditions.
What this means for you: When a single leaf, bird dropping, or shadow from your water tank covers one cell — a TOPCon panel drops output for the entire string (up to 35% loss). The Hi-MO X10's 0BB back-contact design lets current route around the shaded cell. Energy loss: 8% vs 35% — 70% better than TOPCon. Over 15–30 years on a Faisalabad rooftop, that difference is measured in hundreds of thousands of rupees.
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 at longi.com/en/modules-authenticity/ — 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.
LONGi — World Records & Global Recognition
LONGi doesn't just claim efficiency leadership — they hold the certified world records. When you buy LONGi through Saigal Solar, you're buying from a company that S&P Global has independently rated as the solar industry's sustainability leader for 2025.
