Sunpower Performance P3 Front View

Engineered for Performance.

Making the conventional, exceptional

SunPower Performance solar panels combine conventional cells with 35 years of materials and manufacturing expertise to deliver panels that surpass the performance, reliability and aesthetics of Conventional Panels.

With a sleek black design that elegantly blends into any roof, the third-generation SunPower Performance 3 panel combines enhanced warranty terms with an expanded active cell area that delivers increased power and efficiency over previous generation panels.

Engineered for Performance.

The elegance you deserve

Since 2015, innovative shingled cell SunPower Performance panels have been delivering the enhanced reliability and durability that energy providers demand. With more than 3 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.

Backed by an industry-leading warranty and an estimated 35-year useful life, SunPower Performance panels wrap conventional front contact cells with 35 years of materials, engineering and manufacturing expertise to mitigate the reliability challenges of Conventional Panel design.

Residential rooftop installation. Elegant design.

Durability that Translates to More Energy

Engineered to stand up to environmental stresses such as shading, daily temperature swings and high humidity, the SunPower Performance 3 panel delivers up to 7% more energy in the same space over 25 years compared to Conventional mono PERC Panels.

An innovative shingled cell design re-engineers conventional solar technology for added strength and enhanced performance.

– Conductive adhesives developed for aerospace reinforce cell connections to withstand the stresses of daily temperature swings.

– Redundant cell connections mitigate the impacts of cell cracks on power output by creating flexible paths for electricity flow.

– Proprietary encapsulates protect cells and minimize degradation from environmental exposure.

A Better Product. A Better Warranty.

25-year Complete Confidence panel warranty

SunPower Performance panels, the most deployed shingled solar panel in the world, are backed by the SunPower Complete Confidence Panel Warranty, the industry’s most comprehensive warranty coverage.

warranty 01

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.

Each SunPower Performance panel is manufactured with the confidence to deliver more energy and reliability over time—and backed for 25 years by the SunPower Complete Confidence Panel Warranty.

• Year 1 Minimum Warranted Power Output 98.0%

• Maximum Annual Degradation 0.45%

• Year 25 Minimum Warranted Power Output 87.2%


  • 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.

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

We built the Performance solar panels for high reliability, high efficiency and low degradation—driving an estimated 8% more energy yield in a fixed space over the first 25 years of operation when compared to Conventional mono PERC Panels.

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