Technical Field

[0001] The utility model relates to the technical field of photovoltaics, in particular to an installation mechanism of a photovoltaic system and a photovoltaic system. Background Art

[0002] The BIPV system includes photovoltaic modules and buildings for placing photovoltaic modules.
