The TCL Solar HSM-BD54-DA465 is a modern 465 W solar panel built around N-type back-contact cells. That means all the electrical connections are on the back, leaving the front completely free of busbars. The result: a sleek, full-black surface as well as higher light absorption, making this panel particularly efficient, up to about 23.5% efficiency.
The panel uses a glass-glass construction, with 2 mm tempered glass on both sides. This construction makes the panel extra robust, less sensitive to moisture, and more resistant to temperature changes. At the same time, the panel is bifacial: the back side can also pick up light, which gives extra yield especially on a reflective surface or raised mounting system.
Electrically, the panel operates around 34-35 volts at maximum power, with a current of about 13.4 amps. The open-clamp voltage is just above 41 volts, which fits well with modern string inverters. The low temperature coefficient of -0.26% per degree keeps the output stable even on hot days.
In terms of size, the panel is similar to other high-power 54-cell modules: about 1757 × 1134 × 30 mm, weighing around 24.3 kg. The mechanical load can handle up to 5400 Pa of snow and 2400 Pa of wind, making it suitable for almost all roofs in the Netherlands.
In short, a powerful, efficient and visually sleek all-black panel with modern back-contact technology, solid glass-glass construction and high reliability – ideal for those seeking maximum power per square meter without compromising on durability or design.
