Can these go on ground mounts
A1 SolarStore
Absolutely. Ground racks or carports work great and often boost bifacial gain by reflecting light off gravel or grass.

Will the all black look match a dark roof?
A1 SolarStore
Definitely. The monochrome cells, black frame, and black backsheet blend in nicely, so most homeowners say they “disappear” on charcoal or black shingles.

About product

TS-BBT54(440) is a model that uses a number of technologies to bring durability and performance to the next level. The N-Type cell technology ensures excellent power output.

To further boost the performance, Thornova Solar employs half-cut cell technology. Each of the panel’s 108 cells is only half the size of a traditional solar cell. This grants TS-BBT54(440) lower resistive losses and better shade tolerance. Not surprisingly, the efficiency of this module is quite high – 22.5%. And while conventional panels use only one side to absorb photons, bifacial modules employ both sides at the same time. Thanks to the technology, this model can be up to 30% more efficient. Cell surface, back foil and frame are completely black, giving the model unrivaled aesthetics. Thornova Solar paid as much attention to durability as they did to performance. TS-BBT54(440) is guaranteed to retain at least 87.4% of output after 30 years. Product warranty for this panel lasts 25 years.

  • 440 W power output
  • 108 half-cut N-Type cells

Increased efficiency of up to 22.5 percent

TS-BBT54(440) ensures maximum power production. The combination of N-Type cell technology and a powerful antireflective coating results in 22.5 percent module efficiency. This is much greater than the average, resulting in significant extra savings over the years of production.

Keeping the cool in high temperatures

Even under extreme heat, TS-BBT54(440) maintains high efficiency. You may take advantage of the sunniest hours because it loses just -0.29% of efficiency for every 1.8°F over 77°F.

High quality standards

Thornova Solar stringent production requirements include various tests to guarantee high quality. The facilities are highly automated, allowing the manufacturer to maintain high standards while keeping warranty claims to a minimum.

Reliability and degradation resistance

Thornova 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 0.4% every year after that. After the 30 years are over, your modules will retain at least 87.4% of their original performance. This 440 W Thornova Solar solar panel also comes with a substantial 25-year product warranty.

Certified for the worst environmental conditions

TS-BBT54(440) is PID, salt, acid, and ammonia resistant. It can also bear mechanical loads of up to 5400 Pa on the front and 2400 Pa on the back. This durability is mostly owing to the 1.38" thick anodized aluminum alloy frame and a layer of protective glass.

Outstanding all-black design

The panel features all-black design which looks great on any roof. The manufacturer ensures excellent cell color by special treatment and selection processes. Thornova Solar engineers use thinner wires to connect the cells together, and at a distance the surface of the modules appears smooth and uninterrupted.
