Legacy SunPower system support

If your solar system was installed through SunPower, you may be looking for information about support, monitoring, or next steps for your Legacy SunPower system. This page is here to help.

In August 2024, SunPower Corporation began a Chapter 11 restructuring process. Later that year, Complete Solaria, Inc. acquired certain assets and now operates as SunPower. This transition brings together the expertise of both organizations to continue supporting solar customers.

If your Legacy SunPower system is powered by Enphase, you can continue monitoring your system, explore upgrade options, and get help from our support team. We’re committed to making sure your system stays up and running—now and in the future.
