What are the key benefits of partnering with SunPower?
As a SunPower partner, you gain access to high-quality solar technology known for its reliability and efficiency. This means fewer service calls and more satisfied customers, allowing you to focus on expanding your client base. Additionally, the partnership offers streamlined operations with the fullest range of solutions from a single supplier, reducing complexity and operational costs.
What happens during power outages?
Unless you have an energy storage battery, 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.
What is the typical cost advantage of using SunPower Performance panels?
Costs vary from project to project. Performance panels generally have a price point that is competitive with Conventional Panels.
What kind of warranty and product reliability can partners expect?

What types of panels are sold under the TCL SunPower brand and how are they different from SunPower panels?
SunPower interdigitated back contact (IBC) M Class panels offer industry-leading efficiency, a 40-year warranty, and enduring reliability in the face of real-world challenges. SunPower Performance panels provide a balance of efficiency and value with TOPCon cell technology facilitating powerful, reliable energy production from a shingled-cell panel design. TCL Solar panels complement the SunPower Maxeon and SunPower Performance product lines with a mix of highly reliable, bifacial back contact and TOPCon panel designs. TCL Solar panels come in a variety of form factors, making them suitable for deployment across residential, commercial, and large-scale installations.
What warranties do SunPower panels come with?
SunPower M Class panels are backed by an industry-leading 40-year warranty, covering performance, product defects, and service. This ensures peace of mind for both installers and customers, offering one of the most comprehensive warranties in the solar industry.
Why is SunPower selling TCL-branded solar panels?
In November 2024, Maxeon Solar Technologies and TCL announced an agreement-in-principle for the sale of Maxeon's EMEA, APAC and LATAM sales and marketing organization to TCL - forming a new solar solutions business unit within TCL that can maximise the benefits of vertical integration—TCL SunPower Global.
The combined innovation, technology leadership, and manufacturing expertise of the two organizations sets the foundation for an integrated energy solutions platform that enables more customers in more locations to take control of their energy future - generating, storing, and using energy in their homes and business more efficiently and cost-effectively than ever. Maxeon Solar Technologies will continue to operate as an independent, publicly traded NASDAQ-listed company solely focused on the U.S. residential, commercial, and utility-scale markets.
