About product

Among the newest offerings of Phono Solar, PSM4 H24TH is part of the TwinPlus 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. 

Another advantage is the half-cut cell technology. PSM4 H24TH 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, PSM4 H24TH efficiency of 20.57% is quite impressive. Phono Solar provides an industry-leading 25-year performance warranty and a 12-year product warranty. 

  • 144 half-cut PERC cells
  • 450 W nameplate capacity
  • 20.57% efficiency
  • 1500 V DC maximum system voltage
  • MC4 connectors
  • 12 years of product and 25 years of performance warranty

More power and efficiency

An already high efficiency of 20.57% is further enhanced by PERC technology. By adding a solid PID resistance and special glass lamination on top, the manufacturer ended up with an efficient and very durable model. Under standard test conditions, PSM4 H24TH outputs 450 W of power.

Keeping the cool in high temperatures

Even under extreme heat, PSM4 H24TH maintains high efficiency. You may take advantage of the sunniest hours because it loses just 0.38% of efficiency for every 1.8°F over 77°F.

High quality standards

Phono Solar strict manufacturing standards include multiple tests to provide extreme quality assurance. The facilities are highly automated, allowing the company to maintain high standards and keep the level of warranty claims very low.

Reliability and degradation resistance

Slow degradation over the next 25 years is guaranteed by Phono Solar. The performance will decrease no more than 2% during the first year and 0.25% annually thereafter. Your modules will retain at least 89.8% of original performance after the 25 years are over. This 450 W Phono Solar solar panel also comes with a generous 12-year product warranty.

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.
