A renowned reputation built on decades pushing the efficiency limits of solar module design exists within the Sunpower brand. However, with a new decade comes a new era for Sunpower, poised to cease solar module manufacturing altogether from 2020 onwards. 

.Manufacturer:  SunPower Solar/ Maxeon.

Series: P-Series, X-Series, Maxeon Series.

Variants: Monocrystalline.

Sunpower ceasing manufacture should be devastating news for the industry as a whole. Remarkably, though, it is not. Maxeon, the pioneering trademark cell design, powering Sunpower solar panels will resume the manufacturing arm as a separate entity.

No matter the corporate structure though, Sunpower’s legacy will continue into 2020. With such, the current Sunpower solar panels and technical specifications are available for a promising compilation of solar module offerings.

Note; Equivalent of (industry standard) residential 60-cell solar panels considered only. Above 3.3 is considered a VERY GOOD score.

Shingled-cell mono.

Presenting a more affordable P-type monocrystalline shingle cell design, the Sunpower P-Series is a new direction for the brand. Although adopting a less expensive design, notable Sunpower qualities remain apparent.

Sunpower solar panels in the P-Series are ideally suited for those who seek the renowned Sunpower brand at a more affordable price point. Less efficient than alternative Sunpower offerings, additional surface area is required to accommodate a similar output.

Maxeon cells.

Even though the Maxeon 3 solar panel is slightly larger in dimensions compared to its X-Series counterparts, the dimensions are still not too dissimilar from a standard 60-cell solar panel at 1690 x 1046 mm. Bolstered by an efficiency upgrade (max 22.6%) the Sunpower Maxeon 3 presents as Sunpower’s new premier solar module offering in 2020.
