The SunPower M-Class solar panel delivers world-record efficiency and is engineered with a 40-year warranty, providing maximum energy production and the industry's longest-lasting peace of mind.
This combination of leading efficiency and unmatched durability ensures you'll generate more power over the lifetime of your system.
SunPower M Class solar panels redefine energy production with cutting-edge technology, delivering unmatched efficiency, reliability, and aesthetics.
Powered by proprietary interdigitated back contact (IBC) technology and a shingled-cell design, these panels are engineered to maximise energy output while standing up to the harshest environmental conditions.
With an industry-leading efficiency of up to 24.5% and a power output of up to 475W, SunPower M Class panels generate more energy than any other solar panel.
They deliver up to 12.3% more energy by Year 25 and retain 93% of their power output, outperforming competitors. Their low degradation rate of just 0.25% per year ensures consistent, long-lasting energy production for decades.
SunPower M Class panels are designed to endure extreme conditions, including high heat, wind, hail, and snow.
Featuring durable copper cell connections, heat-strengthened glass, and a robust frame, these panels resist thermal stress, corrosion, and physical damage.
With impact resilience up to 25mm hailstones and mechanical test loads of 5400 Pa for snow and 2400 Pa for wind, they are built to last for 40 years—and beyond.
Their low temperature coefficient ensures superior performance in extreme heat, while their broad spectral response enhances energy production during low-light conditions, such as dawn, dusk, and cloudy days.
The innovative electrical design minimises reverse bias voltage and reduces hotspot risks, ensuring safe and efficient operation even in shaded areas.
Backed by a 40-year warranty covering product, power, and service, SunPower M Class panels offer peace of mind and long-term value.
With over 40 years of solar innovation, 1900+ patents, and 11 world records in efficiency, SunPower is a global leader in solar technology.
