Solaria - Next generation solar panels

Founded in 2000 when solar energy was virtually non-existent, Solaria was one of the early innovators of next-generation solar panels and systems. Our most recent product, the Solaria PowerXT solar panel, is based on a ground-breaking technology in which solar cells are cut, overlapped (shingled), and more densely packed into the panel to create a substantially higher-power, higher-efficiency panel than conventional solar panels. Starting in 2014, Solaria was an early innovator in developing shingled panels, and has over 250 issued and pending patents in the field.
