如何安装地面太阳能系统? Jan 07,2021

如何安装地面太阳能系统?很多国家在安装地面支架系统有不同的问题存在,例如光照,国家政策,运输,海拔,土壤等等

这里主要是进行关于不同土壤类型的太阳能地面支架安装解决方案。根据海拔,地下水位和环境的不同,土壤可以大致分为:沙土,软质土,岩石和黏土。

根据不同的土壤,一般有4中常见的太阳能地面基础解决方案:螺旋地桩,水泥柱,平面压载,C或者U梁。这些方案大致可以解决不同的土壤问题。

螺旋地桩:

螺旋地桩主要是热镀锌材质,外径有76毫米,长1000-3000毫米且法兰盘是200毫米到220毫米。安装或连接在柱子底部附近的螺旋地桩 一旦打入到适当的深度,螺旋地桩的螺旋部分将会通过在它上面形成一个土壤锥来抵抗被拉出(所以除了砂土和岩石土)。


Xiamen Kseng Metal Tech Company fabricates and installs ground screws of varying sizes to adapt to different soil types. Ground screws work in a wide range of soils and it comes down to how you design the ground screw to accommodate where you’re trying to install into.

To install a ground screw in dense soils, set the screw inside and drive the mount into the ground using a proprietary machinery. In medium-dense to loose soils, ground screws can be driven directly into the ground. And use the ground screw can fast to install, strong, lightweight, low cost, robust, low mess, and kind to the environment.

 

concrete foundations :

Concrete base ground mounts is a highly versatile ground mounted solution that can be widely applied in smaller projects, site with corrosive or swampy soils and installations in regions prone to hurricanes and high winds. The concrete foundation ground mounting method that requires significantly more excavation than narrower, pile-driven foundations: concrete piers. These posts are suspended in holes 12 to 18 in. in diameter, with a depth of 6 to 8 ft., and wet concrete is poured around them.

flat ground ballast:

Flat groundballasted systems are a non-penetrating foundation solution for solar. Racking is attached directly to a footing, block or basket, and concrete is commonly used as the weight to hold it in place. The concrete is either precast, in which posted are mounted to blocks brought to the site; or concrete is poured into basins and cured on-site around the posts.

Deciding which concrete solution to use depends on site conditions, job costs and system size. Flat ground ballasted systems are often used on volatile sites, like landfills, brown fields and Super funds, where the soil cannot be penetrated due to potential contamination.

C /U piles:

C/U piles are a common component across the field of construction, used as structural supports in horizontal and vertical applications in buildings. They are also the most common ground-mount option for solar systems.

C/U piles are installed using a piledriver that pushes them directly into the earth. Racking is then attached to the exposed beam. C/U piles can be mounted in clay, black and sandy soils, and work best when the site is rock-free. The soil’s friction keeps the piles in place.

For C/U piles in sandy soil, embedment depth is based on grain size. Higher water tables can reduce friction and require a pile to be driven deeper than usual.
