Photovoltaic panel manufacturers support as an important part of the photovoltaic power station, it is bearing the weight of the power subject of photovoltaic power station. Support the choice of a direct impact on the safety operation of the photovoltaic modules, breakage and construction investment, choosing the appropriate photovoltaic stents can not only reduce work
photovoltaic panel manufacturers support as photovoltaic power station 【 Photovoltaic power station, is a use of solar energy panels, the use of special materials such as silicon, composed of electronic components such as inverter power generation system, connected to the grid and sending electricity to the grid photovoltaic power generation systems. 】 Important part of it is bearing the weight of the power subject of photovoltaic power station. The choice of stent directly affects the photovoltaic modules' Monomer solar cells cannot be used directly do the power. 】 Running safety, breakage and construction investment, choosing the appropriate photovoltaic stents can not only reduce the project cost, late will also reduce the maintenance cost.
one, photovoltaic bracket type
1, according to the material classification
according to pv support main stress bar adopted by the different material, it can be divided into aluminum alloy stents, steel stents and nonmetal, including non-metallic stent is less, steel and aluminum alloy stent and bracket have their own characteristics.
2 according to the installation classification
2, fixed photovoltaic stents to introduce photovoltaic array of incidence Angle with the sun
' The sun Angle of incidence is point-blank light and the Angle between the surface normals. 】 Change and rotation, receiving solar radiation in the form of fixed. According to the Angle setting situation can be divided into: best Angle fixed inclined roofing, stationary and Angle adjustable stationary.
1, the best Angle stationary
to calculate the local optimal installation Angle, then the entire array using the Angle of fixed installation, is widely used in flat roof power station and the ground.
1, flat roof Concrete foundation stents
flat roof concrete foundation is current the most commonly used in the flat roof plant installations, according to the basic form, can be divided for strip foundation and independent foundation; Support columns and basic way of connection can be through anchor bolt connection' Content: as yet, anchor bolt connection is refers to the part of the bolt rod connected to the ground, held out to part of the through hole, through the nut and tighten. 】 Or directly to the columns embedded concrete foundation.
the advantages: good wind resistance, strong reliability, without destroying the roof waterproof structure.
weakness: the need to make good concrete foundation, and follow-up maintenance enough strength to support the installation, construction period is longer than the other.
2, flat roof Concrete ballast brackets
advantages: simple concrete ballast bracket construction way, making a counter weight can be simultaneously bracket installation, save construction time.
faults: concrete ballast stents, relatively poor ability to resist wind design counter weight weight need to fully consider the local maximum wind.
3, ground station - Concrete foundation stents
the ground power station concrete foundation is varied, according to don't project geological condition, can choose the corresponding installation, the following main introduction cast-in-place reinforced concrete strip foundation, independence and concrete, precast concrete hollow column, such as several of the most common form of concrete foundation installation.
cast-in-place reinforced concrete foundation according to different foundation forms, cast-in-site concrete cast-in-place reinforced concrete foundation can be divided into the Cast-in-situ concrete in the construction site is die casting of the concrete, and generally refers to the mixing of concrete. 】 Pile and cast anchor.
advantage: the cast-in-situ reinforced concrete of foundation excavation earthwork quantity is little, reinforced concrete is small, low cost, fast construction speed.
faults: cast-in-place reinforced concrete foundation construction are susceptible to season and weather to environmental factors such as the construction demand is high, once be unable to adjust.
bar concrete foundation advantages, independent, independence and the expansion of concrete foundation USES the reinforcement bar type, simple construction method, geological adaptability is strong, foundation embedment depth
