About product

PS545M6-10BR is part of the TWINPLUS Series — one of the most recent made by Phono Solar. These panels employ cutting-edge technologies to achieve superior efficiency and reliability. This panel takes full advantage of the Passivated Emitter Rear Contact (PERC) technology that allows it to capture up to 12% more energy. All thanks to a reflective layer on the back. This design maximizes the number of photons absorbed by solar cells. 

Another advantage is the half-cut cell technology. PS545M6-10BR 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. Not surprisingly, the efficiency of this module is quite high – 21.10%. Cell surface, back foil and frame are completely black, giving the model unrivaled aesthetics. Phono Solar provides 12 years of product warranty and guarantees that after 25 years, performance will be at 84.8% or more. 

  • 144 half-cut PERC cells
  • 545 W nameplate capacity
  • 21.10% efficiency
  • 1500 V DC maximum system voltage
  • MC4 connectors
  • 12 years of product and 25 years of performance warranty

Increased efficiency of up to 21.10 percent

PS545M6-10BR ensures maximum power production. The combination of PERC technology and a powerful antireflective coating results in 21.10 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

PS545M6-10BR manages to stay efficient even at high temperatures. For every 1.8°F above 77°F, it loses just 0.05% in efficiency, allowing you to make the most of the sunniest hours.

Quality and reliability

PS545M6-10BR receives multiple quality checks throughout the manufacturing process and is subject to stringent quality and reliability testing. The manufacturing facilities are highly automated, eliminating the risk of human error. Phono Solar is dedicated to quality, safety and reliability to ensure you get the very best.

Low degradation for increased lifespan

The amount of power output loss experienced by these panels during the first year of operation will not exceed 2%. The average yearly power drop from the second to the 25th year will not surpass 0.55%. After 25 years, the module will still produce more than 84.8% of its initial output.

A panel that can handle hail, wind and snow

The 1.38" frame made from anodized aluminum and a layer of protective tempered glass make this module resistant to the foulest of weather. The front side of the modules can resist a 5400 Pa load, and the back side 2400 Pa.

Stunning black aesthetics

The sleek, all-black aesthetics of the panel will complement any rooftop. By using a variety of treatments and selection criteria, the producer guarantees high quality cell color. Engineers at Phono Solar employ smaller gauge wires to link the cells together, creating a seamless appearance.

Hi, I'm Kim and I recently had the Phono 545 TwinPlus panels installed on our roof. I was looking for a solar panel that could produce enough energy for my small business, and this one exceeded my expectations. The 144 cells generate a lot of power even on cloudy days, and the panels blend in well with my roof. The installation and interconnection were quick and easy, and the panels seem durable and well-built.

Hey guys, just wanted to leave a quick review for the Phono 400W solar panels I recently purchased from A1. I gotta say, I'm pretty impressed. The installation process was a bit of a pain, but that's just because I'm not really a DIY guy. Once the system was up and running though, it's been smooth sailing. I've noticed a significant decrease in my energy bills, and it feels great knowing that I'm doing my part for the environment.

A reliable workhorse. But what it has in reliability and affordability it lacks in aesthetics

I need a dozen of these, how much would the shipping cost?
04/19/2023, 00:24
Shipping starts at $250 for up to 8 solar panels, and goes up by $25 with every 4 modules on top of that. Some panels qualify for free shipping when ordering over 10 items.
What kind of racking comes with this panel?
