There are a variety of key technical differences between SunPower Performance solar panels and Conventional Panels, including the design and layout of the solar cells and the electric architecture—which combine to enhance the reliability, performance and aesthetics of Performance panels.

To go into a bit more technical detail, first, we laser cut each SunPower Performance cell into strips and layer them in a shingled configuration to create a ‘hypercell’. This shingled hypercell allows us to fit more active cell area into each panel, boosting power and efficiency. Second, Performance cells are connected with a flexible joint interconnection to offer multiple and redundant paths for energy flow. This allows us to remove the front contact conductive ribbons and solder bonds found in conventional cells that can block active cell area and deteriorate over time, leading to cell failures and power deficits. Finally, SunPower Performance panels feature a unique parallel circuit architecture that significantly limits power loss in shade and soiling. The result is a superior shingled panel constructed with commodity cells, outperforming conventional panels in efficiency, performance and reliability.

Some customers have achieved some clever customised DIY solutions for re-directing surplus power using Enphase APIs, however, Enphase does not currently offer products that re-direct surplus power.​

If the microinverter (or the associated PV module) should fail, only that PV module is offline. The remainder of the system continues to operate as normal – a key benefit of AC modules.​

No, the microinverter is detachable from the PV module so each component can be serviced separately.

SunPower residential and commercial panels are backed by a 25-year limited Combined Power and Product Warranty.

SunPower® Performance solar panels use a combination of TOPCon solar in a highly efficient shingled-cell design, as opposed to SunPower's proprietary back contact technology developed for our Maxeon panels.
