Solar energy is a rapidly growing industry, and the durability and longevity of solar mounting structures are crucial for the efficient functioning of solar power systems. One of the key factors that determine the longevity of solar mounting structures is the type of coating used on them. In this blog post, we will discuss the different types of coatings used on solar mounting structures, their unique properties and the industry standard grading in use.

Anodized coating: Anodizing is an electrochemical process that creates a protective oxide layer on the surface of aluminium. This coating is highly durable, resistant to weathering, and provides excellent insulation. Anodized coatings are often used on aluminium solar mounting structures. AA10 is the common industry standard of anodized coating which is 10 microns thick.

Powder coating: This type of coating is applied as a dry powder and then cured under heat. It is an environmentally friendly process and provides a durable, long-lasting finish. Powder coating is often used for steel and aluminium solar mounting structures.

Galvanized coating: This type of coating is used to protect steel from corrosion. Galvanized coatings are available in two forms: electro-galvanized and hot-dip galvanized. Electro-galvanized coating is applied by electroplating zinc onto the steel, while hot-dip galvanized coating is applied by immersing the steel in a bath of molten zinc. Both types of galvanized coatings provide excellent corrosion resistance. Hot rolled sheets with Hot Dip Galvanizing coat ranging from 80 microns to special coating of 120 microns is the industry standard for hot-dip galvanized coating.

Galvalume coating: This type of coating is a type of alloy coating that is composed of a mixture of aluminium, zinc, and silicon. Galvalume coating is highly corrosion-resistant and provides excellent protection for steel solar mounting structures. 150 AZ coating is the industry standard for Galvalume coating.

PosMAC coating: POSMAC coating is a corrosion-resistant product that is 5 to 10 times stronger resistance than that of a normal hot-dip galvanized steel sheet [GI, GI(H)]with the same coating weight. PosMAC has an excellent cross-section corrosion resistance; normal thick plating products can be replaced with this product. The same processing, assembly, and painting process can be applied to PosMAC as one would apply to GI. GP Sheets with coating upto 550 GSM is the industry standard for PosMAC coating.

In conclusion, the type of coating used on solar mounting structures plays a crucial role in determining the longevity and durability of the structures. The use of anodized, powder, galvanized, Galvalume and PosMAC coatings provides excellent protection against corrosion and weathering, ensuring the efficient functioning of solar power systems. It’s important to choose the right coating based on the specific needs and requirements of the project.

Solar energy is becoming increasingly popular in India, as the country accelerates its efforts to become a leader in clean energy and reduce its carbon footprint. Solar mounting structures are an essential component of any solar energy project, as they support the solar panels and allow them to capture enough sunlight. There are several different types of solar mounting structures to choose from, each with its own unique features and benefits.


Rooftop Mounts: Rooftop mounts are the most common type of solar mounting structure in India, and are typically used for residential and commercial projects. They are available in both railed and rail-less systems, and are generally attached to the roof with bolts or screws. Railed systems have rails that support the solar panels, while rail-less systems attach the panels directly to hardware connected to the bolts/screws. Rooftop mounts are available in sloped and flat roof versions, and can be used to maximize the amount of sunlight captured.


Ground Mounts: Ground mounts are another common type of solar mounting structure in India, and are typically used for larger-scale projects. These mounts are usually constructed of either aluminum or stainless steel, and they are designed to securely hold the solar array in place. Ground mounts can be stationary or adjustable, and they can also be combined with tracking systems to increase the efficiency of the solar array. Ground mounts can further be classified into the following types:

  • Foundation Mount
  • Ballasted Footing Mount
  • Pole Mount
  • Multi Pole Mount (Carports, Sheds)
  • Smart Flowers

Floating Mounts: Floating mounts are a relatively new type of solar mounting structure, and they are becoming increasingly popular in India. As their name suggests, these mounts are designed to float on water, making them ideal for installations on lakes and other bodies of water. Floating mounts are typically constructed of plastic or polymer, and they are designed to securely hold the solar array in place while also allowing for a certain amount of flexibility.

In summary, there are various types of solar mounting structures available in the Indian market, each with its own advantages and disadvantages. Ground-mounted structures are best for large-scale projects, roof-mounted structures are more suitable for small-scale projects, and floating structures offer an innovative solution for water bodies. It’s important to consider factors specific to your needs when choosing a solar mounting structure for a project.

As the demand for renewable energy continues to grow, solar panel installations are becoming increasingly common on homes and businesses. While solar panels are a reliable and cost-effective source of energy, it’s important to remember that their performance and lifespan are largely dependent on proper installation. This is where solar mounting structures come into play.

Solar mounting structures are the framework that holds the solar panels in place and allows them to capture sunlight effectively. These structures can be ground-mounted, roof-mounted, or even mounted on walls or poles. No matter the type of mounting structure, it’s crucial that it is properly designed, engineered, and installed to ensure the stability and efficiency of the solar panel system.

One of the key benefits of using a solar mounting structure is that it helps to optimize the angle and orientation of the solar panels. By positioning the panels at the right angle and facing the right direction, you can maximize the amount of sunlight they capture and, in turn, increase the efficiency of the system. Solar mounting structures also play a critical role in protecting the panels from wind, snow, and other weather-related hazards. Without a proper mounting structure, the panels could become damaged or even come loose, causing significant damage and costly repairs.

In addition to ensuring the stability and efficiency of the solar panel system, proper solar panel installation is also important for safety reasons. Incorrect installation can lead to accidents or injuries, such as falls from roofs or electrocution. By using a professionally designed and installed solar mounting structure, you can ensure that your solar panel system is safe and compliant with local building codes.

In summary, proper solar panel installation is essential for maximizing the performance and lifespan of your solar panel system. Solar mounting structures play a vital role in this process, providing the necessary support and protection for the panels while also optimizing their angle and orientation. When choosing a solar panel installation company, be sure to look for one that uses high-quality mounting structures and has a proven track record of successful installations.
