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.

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.
