Solaria PowerXT 350R solar panel home

At a 355 Watt power rating, this PowerXT™ solar panel is one of the highest power rated 60 cell PV modules available in the industry. The Solaria PowerXT 355R-PD solar panel is ideal for residential solar systems. It’s efficiency allows fewer solar panels, installation time, and 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. These modules are built on its proprietary technology, which utilizes an advanced cell interconnect and module production processes.
