Outstanding technology: SunPower Maxeon cell panel with 20.4% module efficiency

Release:2017/02/17 Company News

Maxeon® solar cell is fundamentally different with its unique technology. Normal cells are very fragile due to its material and structure, while Maxeon cell is built with unique strong copper foundationthis ,so it can deliver unmatched reliability and enables sunpower to build panels with the world record for highest efficiency.

Below info is detailed instruction for this outstanding cell and cell module.


High Performance & Excellent Durability


Engineered for Peace of Mind
Designed to deliver consistent, trouble-free energy over a very long lifetime


Designed for Durability
The SunPower Maxeon Solar Cell is the only cell built on a solid copper foundation. Virtually impervious to the corrosion and cracking that degrade Conventional Panels.

High Efficiency
More than 20%,ideal for roofs where space is at a premium or where future expansion might be needed. This panel can convert more sunlight to electricity producing 31% more power per panel, and 60% more energy per square foot over 25 Years.

Maxeon cell solar panels are designed to wake up earlier, work harder, and turn off later in the day.
So you can make the most of abundant solar energy and the vast savings it brings.

High Energy Production 
Delivers excellent performance in real world conditions, such as high temperatures, clouds and low light.High year one performance delivers 7-9% more energy per rated watt. This advantage increases over time, producing 20% more energy over the first 25 years to meet your needs.

Performance Beyond Compare
It’s easy to see why conventional panels just don’t stack up against SunPower® technology.


SunPower Maxeon Cell VS  Conventional Cell

No Grid Lines on Front of Cell
Maxeon cells obsord more sunlight and look incredible on roof

Lines of Metal Paste on Front of Cell
Power output drops as the thin paste reflects light and corrodes

Solid Copper Backing
Our thick copper foundation adds massive strength and is almost impervious to corrosion

Even More Metal Paste on Back of Cell
Offers no strength.Cell can crack and lose power when exposed to temperature swings

Thick Connectors
Expanding and contracting from daily temperature swings are no problem with our built-in strain relief

Thin,Weak Connections
Lose just one of these narrow ribbons and the entire cell fails
