Installation methods of solar energy in sloping roof residences

There are mainly two ways to install solar energy in sloping roof residences:

Install photovoltaic panels directly against the inclined tile surface

Installation location selection: Install the photovoltaic panels on the unobstructed south slope and east and west slopes, and fix them directly on the tile surface. This installation method has a high power generation efficiency and a high fit with the roof.

Specific operation

Layout and positioning: Determine the installation position, make proper markings, and ensure the accuracy and standardization of the installation.

Install the hooks: Remove the tiles at the corresponding position, position the installation holes, then drill holes, place the expansion bolts, put the hooks in place and tighten the bolts, apply waterproof glue and reset the tiles. Install the remaining hooks in sequence.

Guide rail installation: After the hooks are installed, install the guide rails to provide support for the subsequent installation of the solar panels.

Solar panel installation: Place the solar panels on the guide rail, put in the grounding conductive sheet, install the edge press block, and install the middle press block for the solar panel wiring installation. Install all the solar panels in sequence.

Electrical connection and equipment installation: Determine the cable path and the installation position of the distribution box, install the inverter and the grid connection box, connect the string DC cable, connect the AC side cable of the inverter to the grid connection box, connect the grid connection side cable of the grid connection box to the power grid, connect the grounding wire of the inverter casing to the grid connection box, and lead the grounding wire of the grid connection box to the grounding electrode. Finally, ground the photovoltaic array.

Install photovoltaic tiles throughout the steel structure

Installation advantages: The steel structure is directly and fully covered on the roof, providing excellent waterproofing effect.

Installation points

Steel structure construction: According to the size and shape of the roof, build a suitable steel structure frame to ensure its stability and load-bearing capacity.

Installation of photovoltaic tiles: Install the photovoltaic tiles on the steel structure frame, paying attention to the connection and sealing between the photovoltaic tiles to ensure waterproof performance.

Electrical connection: Make electrical connections in accordance with relevant standards to transfer the electrical energy generated by the photovoltaic tiles to devices such as inverters.
