Maxwell Equation do not take into account the quantum nature that comes after introducing the Planks constant. The energy of a photon is Planck constant X frequency. There is no Planck constant in Maxwell equations in this sense they are termed classical. To explain photoelectric effect the quantum nature of light has to be assumed.
