About product
Among the newest offerings of Canadian Solar, CS6.1-54TM-445H is part of the TOPHiKu6 (All-Black) series. These panels use state-of-the-art technology to achieve high efficiency and dependability.
CS6.1-54TM-445H employs monocrystalline silicon — the most efficient material for converting sunlight into electricity. Each of the model's 108 solar cells consists of a single crystal, unlike cheaper polycrystalline cells that are made of multiple crystals melted together. As a result, not only are monocrystalline panels more efficient, but they are also more resistant to degradation.
Another advantage is the half-cut cell technology. CS6.1-54TM-445H has solar cells half the size of those installed in conventional panels. The main benefits are decreased power loss, improved longevity and better low-light performance. Given its size and weight, CS6.1-54TM-445H efficiency of 21.8% is quite impressive. Cell surface, back foil and frame are completely black, giving the model unrivaled aesthetics. Canadian Solar provides 25 years of product warranty and guarantees that after 30 years, performance will be at 87.4% or more.
Canadian Solar TOPHiKu6 (All-Black) panels have a high efficiency of 21.8 percent and take full advantage of the company's technologies, which have won Canadian Solar several honors. This I don't know option produces more electricity per square foot of PV modules. This translates to shorter installation times and fewer clamps and racks. All of this lowers your overall expenditures and shortens the payback period.
A low temperature coefficient provides more energy output at high working temperatures. CS6.1-54TM-445H loses just -0.29 percent efficiency for every 1.8°F over 77°F.
CS6.1-54TM-445H is subject to rigorous quality and reliability testing as well as many quality checks throughout the production process. The level of automation in the manufacturing facilities virtually eliminates human error. To guarantee that you receive the finest, REC is committed to quality, safety and dependability.
Canadian Solar guarantees slow deterioration over the next 30 years. The performance will decline by no more than 1% during the first year and then by no more than 0.40% every year after that. After the 30 years are over, your modules will retain at least 87.4% of their original performance. This 445 W Canadian Solar solar panel also comes with a substantial 25-year product warranty.
CS6.1-54TM-445H design makes it suitable for both residential and business rooftops. The use of a strong 1.38" frame composed of anodized aluminum boosts durability and strength. The model can withstand a significant snow load of up to 8100 Pa. The panel's back can withstand 6000 Pa, guaranteeing that your system will resist even the fiercest winds.
The panel features all-black design which looks great on any roof. The manufacturer ensures excellent cell color by special treatment and selection processes. Canadian Solar engineers use thinner wires to connect the cells together, and at a distance the surface of the modules appears smooth and uninterrupted.
