Detailed Information

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 PS-20-UHB lower resistive losses and better shade tolerance. At 20.31% efficiency, PS-20-UHB offers surprising performance for its weight and size. Cell surface, back foil and frame are completely black, giving the model unrivaled aesthetics. Phono Solar offers 12 years of product warranty and guarantees 84.8% of original performance after 25 years of operation.
