SunPower® Performance solar panels combine conventional cells with SunPower's 30+ years of materials and manufacturing expertise to deliver a panel that surpasses the performance, reliability and aesthetics of Conventional Panels.*

  • *. Definition of “Conventional Panel” is a 310W panel, 16% efficient, approx. 1.94 m2, made with Conventional Cells. Conventional Cells are silicon cells that have many thin metal lines on the front and interconnect ribbons soldered along the front and back.


Performance panels for residential installations

SunPower Performance solar panels deliver premium aesthetics for homeowners, while vastly improving on the quality and reliability of Conventional Panel offerings.



Performance panels for commercial rooftops

SunPower Performance solar panels help organizations minimize up-front project costs while providing better savings, performance and reliability than Conventional Panels.



Engineered for reliability

An innovative shingled design addresses the reliability challenges of Conventional Panels.

  • Expands active cell area to capture more energy
  • Uses flexible and redundant cell connections to keep energy flowing
  • Lowers peak cell temperatures to enable longer panel life

Built for performance

Performance panels can deliver up to 32% more energy in the same space over the first 25 years of operation when compared to Conventional Panels.*

SunPower® Performance Panels Frequently Asked Questions

How do SunPower® Performance solar panels differ from Conventional Panels?

There are a variety of key technical differences between SunPower Performance solar panels and Conventional Panels, including the design and layout of the solar cells, the conductive material used, and the electric architecture—which combine to enhance the reliability, performance and aesthetics of Performance panels.

To go into a bit more technical detail, first, we laser cut each SunPower Performance cell into six strips and layer them in a shingled configuration to create a ‘hypercell’. This shingled hypercell allows us to fit more active cell area into each panel, boosting power and efficiency. Second, Performance cells are connected with a conductive adhesive borrowed from the aerospace industry to offer multiple and redundant paths for energy flow. This allows us to remove the front contact conductive ribbons and solder bonds found in conventional cells that can block active cell area and deteriorate over time, leading to cell failures and power deficits. Finally, SunPower Performance panels feature a unique parallel circuit architecture that significantly limits power loss in shade and soiling. The result is a superior shingled panel constructed with commodity cells, outperforming conventional panels in efficiency, performance and reliability.

How do SunPower Performance solar panels differ from SunPower® Maxeon® panel technology?

SunPower® Performance solar panels use high efficiency mono PERC cells, as opposed to SunPower's proprietary back contact technology developed for our Maxeon panels.

What is the typical performance advantage gained from using SunPower Performance panels?

We built the Performance solar panels for high reliability, high efficiency and low degradation—driving an estimated 32% more energy yield in a fixed space over the first 25 years of operation when compared to Conventional Panels.*

What is the typical cost advantage of using SunPower Performance panels?

Costs vary from project to project. However, Performance panels generally have a price point that is competitive with Conventional Panels. Additionally, Performance panels take advantage of many of the materials and processes used to produce nearly 25 million Maxeon panels, delivering the same trusted SunPower quality and reliability.
