Solaria PowerXT 345R-BD 345W Solar Panel

Solaria PowerXT solar panel home

At a 345W power rating, this PowerXT™ solar module is one of the highest power rated 60 cell modules available in the industry. The Solaria PowerXT 345R-BD solar panel is ideal for home solar systems. It's efficiency allows less 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.
