Imagine a modern, sleek black solar panel designed to generate power effortlessly for years to come, that’s the TCL Solar SunPower Performance 7 455 W All Black. This panel combines high output with a neat appearance, making it ideal for rooftops where both performance and looks are important.
At its core, the panel uses monocrystalline N-type TOPCon cells, a modern cell technology known for its high efficiency and slow degradation. The shingled design, where the cells overlap like roof tiles, creates a robust assembly that continues to perform surprisingly well even under partial shade. No standard half-cells, but cleverly overlapping cells that utilize more light and are less likely to develop hot spots.
Its output is 455 watts, with an efficiency of up to about 22.7%. That means the panel manages to extract a lot of energy from every bit of sunlight, ideal if your roof area is limited. Electrically, the panel operates around
With its glass-glass construction, the panel feels sturdy and solid. This type of construction protects the cells on both sides and ensures that moisture and temperature changes have much less impact. The assembly weighs about 22 pounds, with dimensions of 1790 x 1134 x 30 mm, so comparable in size to other high-power panels.
And then the sustainability bit: SunPower dares to offer a 30-year product and power warranty. The first year the yield is allowed to drop a maximum of 1% and after that only 0.4% per year. That means that even after decades, this panel will still deliver a large portion of its power – something not many brands guarantee so strongly.
Finally, there is the aesthetics: everything is completely black, from the cells to the frame. This makes the panel look calm and sleek on dark or modern roofs.
