Outstanding energy density is the priority of many, and your particular project deserves nothing less. Sunpower/ Maxeon 6 is the eagerly awaited next generation solar module by the world renowned module efficiency design leader adding greater  investment versatility over its predecessor, the Maxeon 5. All you have to do is pick one.

Model:  

Sunpower/ Maxeon 6.

Variants:

Maxeon 6 (66-Cell); 420 – 440W.

Maxeon 6 AC (66-Cell); 420 – 440W.

Maxeon 6 BLK (66-Cell); 410 – 425W.

Maxeon 6 COM (72-Cell); 450 – 475W.

TLDR: 

The evolution of the the Maxeon 5 improves on an already outstanding efficiency yet again ensuring a Sunpower Maxeon solar module continues to reign supreme in the world of module energy density in the form of the Maxeon 6. Overall Elite with minor durability variations between models.
