Features:   * The semi-flexible solar panel used is flexible and thin, with anti-penetration contour bending and custom quick installation. * Power tolerance range (output power is within a positive and negative tolerance range of 5%).   * Able to withstand strong wind and snow loads Solar panels can withstand wind loads (1400 Pascal) and snow loads (2400 Pascal). * Color EVA light-conversion film, breaking through the color optical coating transmittance of 99%, making the color of the photovoltaic panel no longer monotonous. * And at the same time, it has the same photoelectric conversion efficiency as the transparent high-transmittance EVA encapsulation film.
