Solaria PowerXT® - High performance, high density solar panels that produce up to 20% more power than conventional modules.

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 power unit assembly. The PowerXT module is electrically designed to reduce the power losses due to shadowing across the module by utilizing parallel connections between sets of sub-strings within each quadrant of the module. By removing visual gaps between cells on the conventional modules, the PowerXT module provides a visually stunning appearance compared to any other solar system. 


  • Higher Efficiency, Higher PowerPowerXT modules achieve higher efficiency over conventional modules, making Solaria modules one of the highest power modules available

  • Lower System CostsHigher efficiency modules produce more power per square meter area, reducing the number of panels, balance of system components, and installation labor

  • Improved Shading ToleranceSub-strings are interconnected in parallel, dramatically lowering the shading losses and increasing energy yield

  • Durability and ReliabilityRibbon-less, solder-free cell-to-cell connections increase reliability and are designed to exceed the 25-year warranty
