SUNPOWER PERFORMANCE 3 DC SOLAR PANEL

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.

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.

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

A Track Record of Innovation Leadership

SunPower Performance panels represent the most deployed
shingled cell panel in the industry—innovation protected by a
growing portfolio of patents worldwide

Engineered for Performance

• Smaller cells stay cooler when shaded, extending panel life
• Advanced encapsulant minimizes degradation from environmental exposure
• Conductive adhesive defends against daily temperature swings
• Redundant cell connections create flexible paths for continuous electricity flow

A Better Product. A Better Warranty.

Each SunPower Performance panel is manufactured with 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%
