A safe investment for your home

Choosing a solar panel can be a once-in-a-lifetime decision, but only if you invest in a technology built and tested for the long term.

The problem?
Standard solar panels are produced and tested in ideal lab conditions—equivalent to noon on a clear summer day. Your panels will need to power through all types of weather conditions to provide the energy you need.

Maxeon panels are designed
• Uninterrupted Energy - Flow from redundant cell connections that protect against temperature swings and moisture-induced corrosion.
• Reinforced Cell - Protection from encapsulant layer designed to absorb stresses and prevent dead zones from forming.
• Extreme Crack - Resistance from solid metal foundation.
• Optional Factory Integrated - Micro inverter operates independently for added safety.

With SunPower Maxeon panels, you are protected from the most common failure points in standard solar
In addition to their durability, they are proven to perform better in shade from passing clouds or soiling built up over time. This protects your panels from developing hot-spots—an electrical failure that occurs when standard cells heat up and shade blocks their ability to create energy. Invest with confidence, knowing that the reliability of your SunPower Maxeon panel is third-party verified as a Top Performer and backed by the industry’s leading warranty.

More energy for your money

SunPower Maxeon panels begin creating more energy than standard solar panels on their very first day.

Each panel is designed to maximise power conversion from sunlight to electricity for your home by:
• Operating at a lower temperature to increase power production in hot, sunny conditions.
• Capturing more sun in low light(2) to ensure your panels are creating power earlier in the morning, later in the evening, and on cloudy days.

When coupled with an industry-leading 40-year warranty, SunPower Maxeon panels multiply in value and provide a better return on your solar investment.


SunPower Maxeon panels are warranted to maintain their efficiency and power output advantage for longer than standard panels.

And a better tomorrow for all

SunPower Maxeon panels are lead-free and made with recyclable materials in our resource-efficient facilities. Each panel benefits from third-party certifications so you do not have to sacrifice premium performance to make a good choice for the planet. SunPower Maxeon solar panels.
