SunPower® Performance
Solar Panels

SunPower® Performance solar panels combine conventional cells with SunPower’s 30+ years of materials and manufacturing expertise to deliver panels that surpass the performance, reliability and aesthetics of Conventional Panels1Definition 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..

Since 2015, SunPower’s innovative shingled cell Performance panels have been delivering the enhanced reliability and durability that energy providers demand. With more than 1.5 GW deployed to date, and backed by an international portfolio of patents and patent applications to secure our technology advantage, we expect SunPower Performance panels to be a force in the market for years to come.

More lifetime energy

Performance panels can deliver as much as 25% more energy in the same space over the first 25 years when compared to conventional panels*SunPower 410 W, 19.9% efficient, compared to a Conventional Panel on same-sized arrays (330 W multi, 17% efficient, approx. 2 m²), 3% more energy per watt (based on PVSim runs for avg US climate), 0.25%/yr slower degradation rate (Jordan, et. al.

Proven reliability

The reality is that not all solar panels are created equal. The reliable operation of your solar panels in real-world conditions is critical to achieving your energy production and savings targets.


Video: Whether from leaves, birds, or neighbouring structures, your installation will ultimately encounter shading. The design and engineering behind your solar panels make a big difference on how reliable they perform when shaded, as well as the savings you’ll see on your electric bill.

In the 2018 DNV GL PV Module Reliability Scorecard, SunPower Performance panels were named as a top performer in all four reliability tests conducted: thermal cycling, damp heat, dynamic mechanical load and potential induced degradation.

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 25% more energy yield in a fixed space over the first 25 years of operation when compared to Conventional Panels1SunPower 410 W, 19.9% efficient, compared to a Conventional Panel on same-sized arrays (330 W multi, 17% efficient, approx. 2 m²), 3% more energy per watt (based on PVSim runs for avg US climate), 0.25%/yr slower degradation rate (Jordan, et. al. Robust PV Degradation Methodology and Application. PVSC 2018; Leidos Engineering. SunPower P-Series Technology Review. 2017)..

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

Costs vary from project to project. Performance panels generally have a price point that is competitive with Conventional Panels.
