SunPower X-Series Solar Panel (Discontinued)

Renewable Innovations does not resell solar panels. Instead, we act as your trusted solar consultant—helping you select the best available modules and coordinate procurement through certified contractors or industry-specific distribution channels. We also assist with system design, proposal optimization, and financing when part of a complete energy solution.
 
SunPower no longer manufactures solar panels. For current high-performance alternatives, we recommend panels from Maxeon, REC Alpha, QCells Q.Tron, or Canadian Solar HiKu7—all of which offer modern support and high-efficiency options suitable for space-constrained or performance-driven systems.
 
SunPower X-Series – High-Efficiency Residential Panel from a Legacy Brand
 
The SunPower X-Series was one of the most recognized premium residential solar modules in the U.S. market, known for its high efficiency, durability, and proprietary back-contact Maxeon cell technology. Rated between 345W and 370W, these panels were commonly used in limited roof space applications where performance and aesthetics were a priority.
 
X-Series panels featured a solid copper foundation, allowing them to withstand thermal expansion, corrosion, and microcracks better than many standard panels. Many SunPower X-Series models were also available as AC modulespaired with built-in Enphase microinverters, offering module-level monitoring and plug-and-play integration with Enphase-based systems.
 
As of 2024, SunPower Corporation has exited the solar panel manufacturing business. The manufacturing arm (Maxeon Solar Technologies) now operates independently, and warranty support may vary depending on the original purchase channel. The X-Series line is no longer in production.
