The fixed solar panel mounting bracket, as the name suggests, refers to a solar panel mounting bracket system whose orientation, angle, etc. remain unchanged after installation. The fixed installation method directly places the solar photovoltaic modules toward low-latitude areas (at a certain angle to the ground), and forms a solar photovoltaic array in series and parallel to achieve the purpose of solar photovoltaic power generation. There are many ways to fix it. For example, there are pile foundation method (direct embedding method), concrete block counterweight method, pre-embedded method, ground anchor method, etc., and the roof fixing method has different schemes depending on the roof material. .
The support of the solar cell array is usually fixed by steel hot-dip galvanized processed products or stainless steel anchor bolts protruding from the reinforced concrete foundation. When the concrete foundation is used on the roof of the house, a part of the waterproof layer of the house is uncovered, and the concrete surface is peeled off. The steel bars of the concrete base for the array are welded together on the steel bars of the patio. When steel bars cannot be welded, in order to use the adhesion and weight of the concrete to resist wind pressure, the surface of the concrete base is uneven to increase the adhesion. After that, a second water repellent treatment is performed with a water repellent filler.
If the above method can not be implemented, you can lay expensive silica gel and other weather-resistant cushioning materials on the waterproof layer, install a hot-dip galvanized steel frame on it, and then fix the array solar panel mounting bracket on the steel frame. The steel frame is connected by plastic bolts to the protruding eaves wall around the house. The purpose is that the wind pressure does not cause the array and the steel frame to move. Play an auxiliary strengthening role.
