Why HPBC?
The "No-Busbar" Revolution.

Traditional panels block sunlight with metal grid lines.

Our HPBC (Hybrid Passivated Back Contact) technology moves all electrical contacts to the back, leaving a 100% unobstructed surface to capture every photon.

The result? Higher efficiency (25%) and a stunning, pure black look.

IP68 Waterproof & Stain-Resistant

We reinvented the fabric solar panel.

The UT-220H features a specialized high-density textured fabric (Chenille style) that is treated with a hydrophobic coating.

It creates a “Lotus Effect”—water beads up and rolls off, taking dirt with it. It offers the luxury feel of fabric with the rugged durability of industrial plastic.

 

Key Features

11.9A High-Current Output

Designed for speed. With an operating current of 11.9A and voltage of 18.5V, the UT-220H pushes the limits of portable charging. It fills up 1000Wh+ solar generators faster than standard 10A panels. Note: For maximum efficiency, we recommend using the XT60 or Anderson connectors.

Only 6.1kg – Travel Lighter

Thanks to advanced composite materials and high-density cells, we shaved off over 1kg compared to traditional panels. At just 6.1kg, it is effortless to carry with one hand, making it the ultimate choice for hiking, RVing, and mobile workstations.

25% High-Efficiency

Powered by next-gen HPBC (Hybrid Passivated Back Contact) technology, the UT-220H eliminates front metal grid lines to achieve 100% light absorption surface. With an industry-leading efficiency of $\ge$25%, it delivers higher energy yield than PERC panels, especially in low-light conditions like cloudy days, dawn, or dusk.

FAQ (Frequently Asked Questions)

Q1: Is the fabric difficult to clean if it gets muddy?

A: Not at all. The fabric is treated with a hydrophobic coating (IP68 rated). Mud and water bead up on the surface and can be easily rinsed off or wiped away, keeping the panel looking premium.

A: We recommend using the XT60 or Anderson connectors for full 11.9A output. The standard DC5521 port is best for lower-power devices, as it may heat up under prolonged high-current (11A+) load.

A: HPBC cells have no metal lines on the front, meaning 100% of the surface area absorbs sunlight. This makes them more efficient (25% vs 23%) and aesthetically superior (Solid Black) compared to PERC panels.
