Your system will automatically shut down. Safety requirements prohibit the system from producing electricity during a power outage or blackout, because there is a chance that the system could feed electricity into the electric grid while utility workers are accessing the grid. The system will restart automatically when power is restored.

Costs vary from project to project. Performance panels generally have a price point that is competitive with Conventional Panels.

All AC module installations must be Internet connected for the monitoring to receive the 25-year microinverter warranty. This Internet connection reports data to the Enphase monitoring platform, Enlighten on a per microinverter/module basis. The performance of each microinverter and module is visible to the installer via Enlighten and alerts are provided for any faulty equipment, such as an under-performing PV module or a faulty microinverter.

Should there be a fire, explosion, gas leak, system damage, or fuel spill around your system’s components, call your local emergency services. If the emergency requires you to seek safety immediately, do so first and then alert emergency personnel that you have a solar system so they can shut it down, if necessary. For assistance restarting your system after an emergency, please contact your Installer.

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.

SunPower® Performance solar panels use high efficiency mono PERC cells, while Maxeon panels use SunPower's proprietary back contact technology developed for our Maxeon panels.
