[0040] As the installed capacity of distributed photovoltaic power stations increases, the existing installation methods of distributed photovoltaic power stations have shown many shortcomings.

[0041] The steps to install a distributed photovoltaic power station in an existing building are: pouring concrete bosses, laying out the steel frame structure, fixing the photovoltaic panels one by one on the steel frame structure, and finally connecting the power station to the grid.

[0042] Due to the variety of existing building structures, the steel frame structure also needs to be adjusted according to the surface where the photovoltaic panels are laid. For example, the sloped roof and the rooftop are suitable for two types of steel frame structures. When laying photovoltaic panels on a surface that cannot be drilled, it is necessary to first cast a concrete boss for drilling holes to fix the steel frame structure.

[0043] Therefore, the construction process of adding photovoltaic panels to existing buildings is relatively complicated, requiring multiple installers to carry out construction according to the structure of the existing building, assemble the steel frame, and then lay the photovoltaic panels.

[0044] In order to quickly install a distributed photovoltaic power station on an existing building, the present application provides a method for adding a photovoltaic structure to an existing building, which can quickly complete the layout of the distributed photovoltaic power station.
