📖 Product Details

Advanced TOPCon BC Technology
The UE485B-54HBD utilizes cutting-edge Back Contact (BC) cell technology. By moving the metal contacts to the rear of the cell, we eliminate front-side shading, resulting in higher current generation, better temperature coefficients, and outstanding performance even when partially shaded.

Bifacial Double-Glass Design
Built with 2.0mm + 2.0mm coated semi-tempered glass on both sides, this module is highly resistant to harsh environmental conditions, including PID, salt mist, and ammonia. The double-glass structure significantly reduces micro-crack risks during transportation and installation, while the transparent backside allows for extra power generation from ground reflection (albedo).

Engineered for Maximum ROI
With a power tolerance of 0 to +3%, you are guaranteed to get the power you pay for. The lightweight (24.3kg) and compact design (1757×1134×30mm) reduce shipping costs (962 pcs per 40' HC) and make installation faster and safer.

FAQS

Q :

What is the advantage of BC (Back Contact) technology over standard solar panels?

A :

BC technology moves all the metal gridlines to the back of the solar cell. This completely eliminates front-side shading, allowing more sunlight to be absorbed. It results in higher power output, a better temperature coefficient, and significantly better performance under partial shading conditions (e.g., passing clouds or nearby trees).

Q :

How much additional power can the bifacial double-glass design generate?

A :

The exact power gain depends on your installation (height, tilt, and structure) and ground albedo (reflectivity of the surface below, like snow or white roofing). With a bifaciality factor of 70±5%, the module can generate up to 10-25% additional energy from the rear side compared to a standard single-glass monofacial panel.

Q :

What are the packaging details and MOQ (Minimum Order Quantity) for shipping?

A :

We pack 37 pieces per pallet. A standard 20-foot container (20' GP) holds 222 pieces, and a 40-foot high cube container (40' HC) holds 962 pieces. We support customized cable lengths and welcome inquiries for mixed container orders.
