In the context of the global advocacy of clean energy, solar energy, as a green, environmentally friendly and inexhaustible energy source, has received widespread attention. As an important part of solar photovoltaic power generation, the applicability of solar roof support system is closely related to the roof type, tile roof type and installation method. The following will introduce in detail the roof type, tile roof type and corresponding installation method in the solar roof support system.
(I) Flat roof
The slope of the flat roof is small, generally less than 10%, and the common slope is 2% - 5%. It has a simple structure, convenient construction, large available area, and can flexibly arrange solar panels. It is widely used in industrial plants, warehouses, large shopping malls, office buildings and other buildings, as well as multi-story residential and affordable housing.
(II) Sloped roof
The slope of the sloping roof is between 10% and 60%, with good drainage performance, which can effectively avoid water accumulation and protect the roof. There are various forms, including single slope, double slope, four slope, etc. It is widely used in civil buildings such as villas, multi-storey houses and traditional houses. Different forms can adapt to different architectural shapes and functional requirements.
(III) Curved roofs
The curved roof has a unique and beautiful shape and is in the shape of a curved surface. It is divided into regular geometric surfaces (such as arches, spheres, paraboloids) and irregular free surfaces. Although it can give the building a unique appearance, it is difficult to construct and has high requirements for the installation of solar energy equipment. It is often used in public buildings with high requirements for appearance (such as cultural and art centers, exhibition halls, gymnasiums) as well as high-end commercial buildings and landmark buildings.
(IV) Metal roofs
The metal roof uses metal materials such as color steel plates, aluminum alloy plates, copper plates, etc. as the roof covering layer. It has the advantages of light weight, high strength, good waterproof performance, corrosion resistance, and fast construction speed. It can be well combined with solar panels to form an integrated system. It is widely used in large-span buildings such as industrial buildings, storage buildings, stadiums, exhibition halls, and buildings with high requirements for durability and energy saving.
(V) Glass roofs
Glass roofs use glass as the main light-transmitting material, which has good lighting performance and can make the interior bright and transparent. Single-layer, double-layer or multi-layer hollow glass, as well as special glass such as coated glass and laminated glass can be used. It is often used in buildings with high lighting requirements, such as greenhouses, sun rooms, commercial atriums, exhibition halls, etc., and is also used in high-end residences and villas to increase lighting and spatial layering.
(I) Cement tiles
Cement tiles are made of cement, sand and other main raw materials, which are mixed, pressed and cured. It has the characteristics of high strength, affordable price, good durability, various colors and styles, and can adapt to different architectural styles. However, it is heavy and has high requirements for the load-bearing capacity of the roof structure.
(II) Ceramic tiles
Ceramic tiles are made of high-quality clay and fired at high temperature. They have good waterproof, heat insulation and decorative properties, bright colors, rich shapes, and a strong traditional flavor. They are often used in antique buildings and traditional-style houses. However, ceramic tiles are brittle and easily damaged during transportation and installation.
(III) Glazed tile
Glazed tile is a kind of ceramic tile with glaze on the surface. It is colorful, glossy and highly decorative. It is a commonly used tile material in traditional Chinese architecture. It has excellent waterproof performance and long service life, but the price is relatively high and the installation process requirements are also relatively complicated.
(IV) Asphalt tile
Asphalt tile is a tile-shaped roof waterproof sheet made of glass fiber felt as the base. After being dipped in asphalt, one side is covered with colored mineral particles and the other side is sprinkled with isolation materials. It has the advantages of light weight, simple construction, rich colors and low price. It is suitable for sloping roofs with large slopes. However, it has poor high temperature resistance and relatively short service life.
(V) Metal tile
Metal tiles mainly include color steel tiles, aluminum zinc steel plate tiles, etc., which have the characteristics of light weight, high strength, good waterproofness, easy installation and long service life. They can adapt to various climatic conditions and can be recycled, meeting environmental protection requirements. However, metal tiles may generate noise during use, and corresponding sound insulation measures need to be taken.
(I) Flat roof installation method
Concrete foundation fixation: Pour a concrete foundation on the flat roof, and connect and fix the bracket to the foundation through embedded parts or expansion bolts. This method has good stability and is suitable for flat roofs with good bearing capacity, but the construction is relatively complex and the cost is high.
Ballast installation: Use heavy objects such as sandbags and concrete blocks to ballast and fix the solar bracket. There is no need to damage the roof waterproof layer. It is convenient to install and has little impact on the roof structure. However, it is necessary to check the stability of the ballast regularly. It is suitable for situations where there are strict restrictions on roof damage.
Piercing installation: Penetrate the roof structure through bolts and other connectors, and fix the bracket directly to the roof load-bearing structure. The installation is firm, but it will damage the roof waterproof layer. Waterproof treatment is required to prevent leakage.
(II) Sloped roof installation method
Hook installation: Install a special hook on the purlin or rafter of the sloping roof, and then connect the bracket to the hook. This method does not damage the roof tiles, is easy to install, has little impact on the roof structure, and is suitable for most sloping roofs.
Guide rail installation: Lay the guide rail along the slope of the sloping roof, and then fix the solar panel on the guide rail. The guide rail can be customized according to the roof slope and the size of the panel, with high installation accuracy, which can effectively improve the installation efficiency and stability of the panel.
Direct fixation: For some special sloping roof structures, such as wooden roofs, the bracket can be directly fixed to the wooden beams of the roof by bolts. However, it is necessary to ensure that the bearing capacity of the wooden beams meets the requirements and that anti-corrosion treatment is done.
(III) Tile roof installation method
For cement tiles, ceramic tiles, and glazed tiles: Use special tile hooks or clamps to fix them on the purlins of the roof, and then connect the bracket to the tile hooks or clamps. Be careful during installation to avoid damaging the tiles, and ensure that the tile hooks or clamps are firmly installed to ensure the stability of the bracket system.
For asphalt tiles: Because asphalt tiles are thin and soft, wooden or metal keels are usually installed first, and then the bracket is fixed to the keel. The keel can provide better support and stability, and also protect the asphalt tiles from damage.
For metal tiles: self-tapping screws or special clamps can be used to fix the bracket directly on the metal tiles. During installation, pay attention to the spacing and tightening strength of the screws or clamps to prevent deformation or leakage of the metal tiles, and do a good job of rust prevention.
From various roof types to rich types of tile roofs, each form corresponds to a unique installation strategy, which together builds a complete system of solar roof bracket system. With the accelerated arrival of the clean energy era, in-depth understanding and reasonable application of this knowledge can not only help us to efficiently utilize solar energy resources, but also contribute to sustainable development. Whether it is building owners, engineers, or everyone who pays attention to energy transformation, they can find a way to achieve a green future from the solar roof bracket system. Let us use scientific installation methods as a bridge to transform the roof into a production base for clean energy and open a new chapter in the use of green energy.
