About product

PS365M4H-20 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. The Passivated Emitter Rear Contact (PERC) technology ensures excellent power output. This solar cell type employs an additional reflective layer to absorb more sunlight. To further boost the performance, Phono Solar employs half-cut cell technology. Each of the panel’s 120 cells is only half the size of a traditional solar cell. This grants PS365M4H-20 lower resistive losses and better shade tolerance. Not surprisingly, the efficiency of this module is quite high – 19.9%. Cell surface, back foil and frame are completely black, giving the model unrivaled aesthetics. Phono Solar provides a 12-year product warranty. Stable power output is also guaranteed — performance warranty will protect you during 25 years.

  • 365 W power output
  • 120 half-cut PERC cells
  • 19.9% efficiency
  • 1500 V DC maximum system voltage
  • MC4 compatible connectors
  • 12-year product and 25-year performance warranties

High efficiency of 19.9%

Phono Solar Twinplus panels take full advantage of the company’s technologies that have won Phono Solar multiple awards. This PERC option offers higher power output per square foot of PV modules. This means quicker installation times and fewer clamps and racks. All of which reduces your overall costs, shortening the payback time.

Keeping the cool in high temperatures

PS365M4H-20 manages to stay efficient even at high temperatures. For every 1.8°F above 77°F, it loses just 0.3% in efficiency, allowing you to make the most of the sunniest hours.

Quality and reliability

PS365M4H-20 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 a longer lifespan

These panels will lose no more than 3% of their power output in the first year of service. From the 2nd year to the 25th year, the average annual power decline will be no more than 0.7%. The module retains over 80.2% of its original output after 25 years. Guaranteed by Phono Solar.

Certified for the most challenging environmental conditions

PS365M4H-20 is resistant to PID, salt, acid and ammonia. It can also withstand up to 5400 Pa mechanical load on the front and 2400 Pa on the back. Such robustness is mainly due to the 1.38" thick anodized aluminum 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. Phono Solar engineers use thinner wires to connect the cells together, and at a distance the surface of the modules appears smooth and uninterrupted.

So far, everything appears okay. I believe we generate around 40 each day, but I'm not sure. The most generation happens from 10 am to 4 pm.

Need a few more months and bills before I can comment on our new system. But the store did a great job, we enjoyed working with you guys

Due to the configuration of our roof, the system had to be divided into three arrays, each having 16 panels facing west and 8 panels facing north. We generate 40 kWh on average daily and nearly 60 kWh on clear days. For our purposes, the micro inverters are wonderful. We couldn't produce anything close to these numbers using a string system.
