At a 320W power rating, this PowerXT™ solar module is one of the highest power rated solar panels available in the industry. The PowerXT module is ideal for residential solar systems that can benefit from producing more power in less space. The 320R-BX requires fewer solar panels, less installation time, and lower cost of balance of system components required for a project.

Developed in California, Solaria’s patented cell cutting and assembly form ‘high density’ sub-strings, larger than conventional solar cells, which are packed more efficiently and reduce inactive space between cells. By utilizing a ribbon-less interconnection process, cells are cut and overlaid without soldering which creates a highly reliable sub-strings assembly.

Solaria PowerXT 320R-BX All-Black Solar Panel Review

PVEL tested - advancing solar

"Solaria makes the highest wattage all-black solar panels available by a wide margin." The Solaria 320R-BX is virtually “All Black”, nothing else is really like it. 

Higher Efficiency, Higher Power
With 18.7% efficiency, higher than conventional 60 cell modules at 16-17% efficiency.
Large form factor resulting in one of the highest power solar panels available on the market.

Lower System Costs
The higher power module translates to less modules required per area, reducing the balance of system components and installation costs.

Improved Shading Tolerance
Sub-strings are interconnected in parallel within each row, dramatically lower shading losses and increasing energy yield.

Rugged Design
Thicker glass and frame provides a rugged module design ideal for ground-mount and tracker applications.

Durability and Reliability
Ribbon-less, solder-free design removes wiring between cells, designed for reliability beyond 25 years.

Solaria is a 100% US owned solar manufacturer and manufactures in Silicon Valley, California and South Korea.
