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.

A simulated PV system performance has been evaluated in Madrid with the following results for roofs with limited space available:

• 30% more power on the roof
• 42% higher performance
• Half the degradation

In a space unconstrained situation also in Madrid:

• 10% higher yield
• Half the degradation
• Similar cash flows
• Lower risk for future maintenance

SunPower systems will also benefit from leading warranty coverage—up to 40 years in the case of SunPower Maxeon AC panels. Enphase microinverters are warranted for 25 years. For assumptions and a personalized simulation, please contact us to be connected to a SunPower installer.​

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.​

All grid-connected modules with integrated inverters must comply with all the requirements and tests established in parts 1 and 2 of the UNE-206007 Report. Prior to the connection and/or contracting of self-consumption, and as indicated in section 4 of part 2, this compliance must be certified by a certification body accredited according to UNE-EN 1S0/IEC 17065.

No. If there are no SunPower Partners in your area, we will pair you with a qualified installer, or you can appoint an installer of your choice.

That’s ok. You can claim cashback so long as you pay your solar installer for your SunPower home energy system on or before June 30th 2024. The installation date can be later.
