One of the most important features of any type of solar photovoltaic component assembly component is weatherability. It must be ensured that the structure must be robust and reliable for 25 years, such as environmental erosion, wind and snow loads and other external effects. Safe and reliable installation, maximum installation efficiency, almost maintenance-free, reliable maintenance, and recyclability with minimal installation costs are important factors to consider when making alternatives. At present, some photovoltaic bracket enterprises apply high wear-resistant materials to resist wind and snow loads and other corrosive effects, and comprehensively utilize aluminum alloy anodizing, ultra-thick hot-dip galvanizing, stainless steel, anti-UV aging and other technical processes to ensure solar energy support and solar energy. Track the service life.

Common forms of photovoltaic supports

Photovoltaic stents are available in a variety of classifications, such as welding and assembly according to the connection method. They are divided into fixed and daily depending on the installation structure, z profile steel manufacturer,and are divided into ground and roof according to the installation location. Regardless of the type of photovoltaic system, the brackets are generally similar, including connectors, columns, keels, beams, and auxiliary parts.

Fixed PV bracket refers to the bracket system whose orientation, angle, etc. remain unchanged after installation. The fixed installation method directly places the solar photovoltaic modules toward low latitudes (at an 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 various fixing methods. For example, the ground fixing method includes pile foundation method (direct embedding method), concrete block weight method, pre-buried method, ground anchor method, etc. The roof fixing method has different schemes depending on the roofing material. .

Photovoltaic stents for solar arrays are typically secured by steel hot dip galvanized workpieces or stainless steel anchor bolts that extend from the reinforced concrete foundation. Where a concrete foundation is used on the roof of the house, the waterproof layer of the house is uncovered and the concrete surface is peeled off. The reinforcing bars of the concrete blocks for the array are welded together on the steel bars of the patio. When the steel bar cannot be welded, in order to resist the wind pressure by the adhesion of the concrete and the self-weight, the surface of the concrete base is uneven and the adhesion is increased. Thereafter, a secondary waterproofing treatment is performed with a water-repellent filler.

If the above method cannot be carried out, a weather-resistant cushioning material such as a relatively expensive silica gel may be applied to the waterproof layer, and a heavy-weight steel skeleton of hot-dip galvanizing may be attached thereto, and then the array holder may be fixed on the steel skeleton. The steel skeleton is connected by plastic bolts to the protruding wall around the room. The aim is that the wind pressure does not move the array and the steel skeleton. Provides auxiliary reinforcement.
