635W Back Contact (BC) Solar Panel | 23.5% High-Efficiency Monocrystalline Module
Specifications
How we verify OE matching
Every EV battery SKU is cross-checked against the manufacturer's original part number before shipping. Three-step verification process:
-
1
OE number cross-reference. Catalog part number matched against the OEM's published reference for the target vehicle (Toyota, Honda, BYD, Tesla, etc.). Identical OE = guaranteed fitment.
-
2
Cell-level grading. Each pack is assembled from capacity-matched and internal-resistance-matched cells. Voltage, IR, and self-discharge values recorded against the OE spec.
-
3
Diagnostic compatibility check. BMS protocol calibrated to the target vehicle's ECU so the pack registers without re-coding for most hybrid applications.
Description
635W Back Contact (BC) Solar Panel — Premium High-Efficiency Monocrystalline Module The LIANLI 635W back contact (BC) solar panel represents the cutting edge of monocrystalline PV technology. By relocating all electrical contacts to the rear of the cell, BC modules achieve 23.5% module efficiency — among the highest commercially available — while presenting an unobstructed all-black front surface for maximum light absorption. Key Specifications Peak Power (Pmax): 635W Module...

FAQ
Frequently Asked Questions
▸ What is the actual output of the LLSP-635W?
Under STC (1000W/m2, AM1.5, 25C cell temperature), the LLSP-635W delivers its nameplate wattage with +/-3% power tolerance. Real-world output typically ranges 85-92% of STC depending on irradiance, temperature, and soiling losses.
▸ Is this panel compatible with my inverter and racking?
Yes. Standard MC4 connectors and 30mm/35mm/40mm frame thickness options ensure compatibility with all major string and micro inverters (SMA, Fronius, Sungrow, Huawei, Enphase) and rail-based or ballasted racking systems from Schletter, K2, IronRidge, and Ecofasten.
▸ What certifications and warranty apply?
All LIANLI solar panels carry IEC61215, IEC61730, UL61730, CE, and ISO9001/14001 certifications. Linear performance warranty: 25 years to 84.8% of initial power output. Product workmanship warranty: 12 years.
▸ Do you ship internationally and what are the terms?
Yes. Panels ship via 40HC containers (typically 700-900 pieces per container depending on wattage and frame size). FOB, CIF, and DDP terms available for major destinations. Pallet packaging with corner protection included.
▸ What is the difference between PERC, TOPCon, and HJT cell technologies?
PERC (Passivated Emitter Rear Cell) is the proven mainstream technology with 19-21% efficiency. TOPCon (Tunnel Oxide Passivated Contact) adds a rear-side passivation layer for 22-24% efficiency and better bifacial gain. HJT (Heterojunction) combines amorphous and crystalline silicon for 24-26% efficiency with superior temperature coefficient and bifaciality.
