Not all solar systems are created equal. Of all solar panels on the market, SunPower panels convert more sunlight into electricity. This means our solar panels generate more power than conventional panels1 within the same amount of space and you’ll need fewer solar panels to produce the energy you need. You can maximise your available roof space to choose the best, unobstructed location for electricity production. You'll save more money on electricity costs over time with SunPower.
Every single panel is electrically tested and inspected for cosmetic criteria at the end of the production line. Regardless of the cosmetic grade, the cosmetic effects do not affect performance or reliability.
We built the Performance solar panels for high reliability, high efficiency and low degradation—driving an estimated 8% more energy yield in a fixed space over the first 30 years of operation when compared to Conventional mono PERC Panels1.
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.
As TCL panels are sold both directly through our installers as well as selected distributors, any perceived warranty claims should be directed back to the installer or the distributor from which the panels were purchased. In line with published warranty terms and conditions, installers and distributors will be positioned to review and remedy claims, or escalate to TCL SunPower as necessary.
SunPower’s interdigitated back contact (IBC) Maxeon panels are renowned for their industry-leading efficiency, 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.
