When installing the photovoltaic component 100, it can be installed directly through the mounting portion 132 without performing other operations, thereby further reducing the difficulty of installing the photovoltaic component 100 on buildings or other objects.

[0046] Specifically, if Figure 4 As shown, the second cover plate 130 protrudes from the first cover plate 110 in a direction AB, which may be along a stacking direction CD perpendicular to the first cover plate 110 and the second cover plate 130 .
