Achieving over 19% efficiency, Solaria PowerXT solar modules are one of the highest power modules in the residential solar market.

Compared to conventional modules, Solaria PowerXT modules have fewer gaps between the solar cells; this leads to higher power and superior aesthetics. Solaria PowerXT residential modules are manufactured with black backsheet and frames, giving them a striking appearance.

Developed in California, Solaria’s patented cell cutting and module assembly form high-density sub-strings, 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 highly reliable sub-string assemblies in a cost effective manner.

Higher Efficiency, Higher Power
Solaria PowerXT modules achieve over 19% efficiency; conventional modules achieve 15% – 17% efficiency. Solaria PowerXT modules are one of the highest power modules available.

Lower System Costs
Solaria PowerXT modules produce more power per square meter area. This reduces installation costs due to fewer balance of system components.

Improved Shading Tolerance
Sub-strings are interconnected in parallel, within each of the four module quadrants, which dramatically lowers the shading losses and boosts energy yield.

Improved Aesthetics
Compared to conventional modules, Solaria PowerXT modules have a more uniform appearance and superior aesthetics.

Durability and Reliability
Solder-less cell interconnections are highly reliable and designed to far exceed the industry leading 25 year warranty.
