Among the newest offerings of Philadelphia Solar, M144(HCBF) is part of the 550W Wholesale series. These panels use state-of-the-art technology to achieve high efficiency and dependability. 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.

To further boost the performance, Philadelphia Solar employs half-cut cell technology. Each of the panel’s 144 cells is only half the size of a traditional solar cell. This grants M144(HCBF) lower resistive losses and better shade tolerance. Given its size and weight, M144(HCBF) efficiency of 21.3% is quite impressive. 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. The innovations made the appearance of the panel as impressive as the specs. A mere 1.38" thick, this model is completely black with a smooth surface. This beauty doesn’t compromise the quality or reliability of the panel. Philadelphia Solar provides an industry-leading 25-year performance warranty and a 12-year product warranty.

• 550 W power output

• 12-year product and 25-year performance warranties

Increased power and efficiency

PERC technology improves on an already high efficiency of 21.3 percent. The manufacturer created an efficient and highly durable model by adding a robust PID resistance and unique glass lamination on top. M144(HCBF) produces 550 W of power under standard test conditions.

Exceptional performance in hot temperatures

A low temperature coefficient provides more energy output at high working temperatures. M144(HCBF) loses just -0.35 percent efficiency for every 1.8°F over 77°F.

High quality standards

Multiple tests are part of the Philadelphia Solar tight production requirements, which offer the highest level of quality assurance. Because of the facilities' high degree of automation, the business is able to uphold strict standards and minimize the number of warranty claims to an absolute minimum.

Reliability and degradation resistance

Slow degradation over the next 25 years is guaranteed by Philadelphia Solar. The performance will decrease no more than 2% during the first year and 0.25% annually thereafter. Your modules will retain at least 87.5% of original performance after the 25 years are over. This 550 W Philadelphia Solar solar panel also comes with a generous 12-year product warranty.

Improved frame design

M144(HCBF) 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 5400 Pa. The panel's back can withstand 2400 Pa, guaranteeing that your system will resist even the fiercest winds.

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 Philadelphia Solar employ smaller gauge wires to link the cells together, creating a seamless appearance.
