Ground mounting is the general choice for installing solar power systems in rural areas. Compared to roof mounting, ground mounting is easy to construct, easy to maintain, and also flexible to adjust the angle according to the light conditions. Today we will introduce 3 kinds of ground solar racking options suitable for rural areas to help you choose the most suitable installation.
Option 1: Concrete foundation fixed mounting
This type of mounting is the most traditional and solid, suitable for long-term home solar system. During construction, a pit will first need to be dug and concrete poured to create the foundation. The galvanized steel mounts will then be secured to the concrete piers. This solution is very wind-resistant and has a service life of more than 25 years, making it particularly suitable for windy areas. However, the pre-construction is relatively complex and usually requires a 3 to 5 day maintenance period. This approach is ideal for farmers who have a fixed site and do not intend to move their solar panels. When installing, special attention needs to be paid to the depth of the foundation, which should usually exceed the local permafrost layer, and for northern regions, it is recommended to reach more than 1 meter.
Option 2: Helical Ground Pile Mount
If you find it too troublesome to drive concrete, spiral ground stake is a time-saving option. The support is directly mechanically screwed into the ground, and the installation can be completed on the same day, especially suitable for loose sandy or clay soil. The bracket attached to the top of the ground stake can be adjusted in height and angle, and can be easily remodeled if you want to move the position at a later date. It is slightly more expensive than a concrete foundation, but saves labor and time costs and is suitable for farmers who want to install quickly or lease land for solar installation. It should be noted that rocky plots are not suitable for helical ground piles and may experience difficulty screwing in.
Option 3: Counterweight block support
For those who are worried about damaging the ground, such as temporary land or farmers who are afraid of destroying cultivated land, counterweight block support is the best option. This kind of support directly uses cement blocks, sandbags and other heavy objects to press down on the support base, without digging or piling. It is the easiest to install and can be dismantled and moved at any time, which is especially suitable for the planting mode of “solar energy + agriculture”. However, the wind resistance is relatively weak, suitable for the plains where the wind is not strong, and the weight should be calculated when installing, generally each solar panel needs 200-300 kilograms of ballast. Low crops can be planted around the mounts, which do not interfere with power generation and allow for continued farming.
Installation of any choice of program, need to pay attention to due south, tilt angle adjusted according to the local latitude (generally take the local ± 5 °), so that the highest power generation efficiency, stent spacing needs to be enough, the front row do not cover the back row of light. Rural installation of solar racking can be used to utilize unused land, while increasing income, choose the right installation can also make the solar energy system safer and more efficient operation.
