SES is thrilled to be a SUNPOWER Authorized Dealer because SUNPOWER has the highest efficiency, most durable panels on the planet. Key to the efficiency and durability is the Maxeon technology that powers their solar cells.
No grid lines on the front of the panel means that more sun gets through, solid copper backing with thicker connectors means less cell failure. The consequence of all this superior engineering is that SUNPOWER now offers some of the highest wattage residential solar panels on the the market; including the 400W panel which we have in stock now and use on many of our projects.
