Which is better for attaching solar panels: GI structure or aluminium structure?

The choice between a GI structure and an aluminum structure for mounting solar panels depends on various factors such as cost, durability, weight, and maintenance.

 

GI (Galvanized Iron) mounting structures are a cheaper option and can be used for small-scale solar projects. However, GI structures are not as durable as aluminum structures, and they tend to rust and corrode over time. This can lead to a shorter lifespan and higher maintenance costs.

 

 

Aluminum structures are more expensive than GI structures, but they are more durable and long-lasting. They are also lightweight, which makes them easier to install and transport. Aluminum structures are resistant to corrosion and rust, which means they require less maintenance over their lifetime.

 

 

When considering a solar mounting structure, there are a few things to keep in mind:

 

 

Load-bearing capacity
The mounting structure should be able to bear the weight of the solar panels and any additional loads such as wind.

 

 

Tilt angle
The mounting structure should be adjustable to ensure that the solar panels are at the optimal tilt angle for the specific location.

 

 

Installation
The mounting structure should be easy to install and should come with all necessary hardware and instructions.

 

 

Weather resistance
The mounting structure should be designed to withstand all types of weather, including high winds, heavy and rain.

 

 

To determine whether a mounting structure can withstand all types of weather, it is essential to consider the wind and snow load capacity of the structure. The wind load capacity is the amount of wind pressure that the structure can withstand, and the snow load capacity is the weight of snow that the structure can hold.

 

 

The wind load capacity of a solar mounting structure depend on various factors such as the height of the structure, the location, and the specific design of the structure.

 

 

These values can be calculated by a structural engineer, and it is recommended to choose a mounting structure that has been tested and certified to meet the relevant safety standards.
