Solar installations have been rapidly increasing around the world. India has contributed a significant portion of the expansion, and with a target of 100 GW by 2022, it is on the verge of becoming the world's largest solar nation. Continuous price reductions in solar systems as a result of higher grid rates are growing global demand for solar solutions, resulting in significant growth. Solar is undeniably the way of the future and a leading sustainable energy source.

Solar rooftop module mounting structure refers to a system used to mount solar panels or modules on the roof of a building. The purpose of this structure is to provide a stable and secure platform for the panels, while also allowing for ease of maintenance and installation. The structure typically consists of a series of aluminum or steel frames, mounting rails, clamps, and brackets, which are used to attach the panels to the roof and keep them in place.

There are several types of solar rooftop module mounting structures, including ground-mounted systems, ballasted systems, and rooftop-mounted systems, each with its own set of advantages and disadvantages. The type of structure used depends on the specific requirements and constraints of each project, including the size and orientation of the roof, the local climate, and the available budget.

Solar module mounting structures are the supporting pillars of PV modules installed to generate electricity from sunlight. These structures set the solar panels at an angle that can collect maximum solar radiation.

Solar mounting structures are one of those crucial components of a solar system that contribute significantly to increasing the output produced. This is because solar panels, the electricity-generating gadgets function favorably when the sunlight they absorb is shade free and active for long hours of the day. For this, the panels should be mounted at a critical tilt angle.

Types of Solar Module Mounting Structure

Every location for solar system installation is not the same, same is the case with Solar Module Mounting structure. There are different applications, terrain and environmental references. Hence, an individual structure can not be favourable to every single customer. And this calls for the need for several types of solar mounting structures. So there are three types of solar mounting structures namely:

  • Rooftop Mounting Structure

  • Tin Shed Mounting Structure

  • Ground Mounting Structure

All these 3 types of solar mounting structure can further be classified into several categories. Below is the detailed information about all types of solar panel mounting structure.

Solar Rooftop Module Mounting Structure

HV Solar is one of the leading solar module mounting structure manufacturer and supplier in North India. In a rooftop mounting system, Solar PV panels are installed on the roof of the building. It can either be any residential building or any commercial/industrial building. The rooftop mounting structure is further divided into two types which are-

  • Standard Rooftop Structure

  • Elevated Rooftop Structure

Let’s know more about these types of rooftop mounting structures one by one.

Standard RCC Rooftop Module Mounting Structure

Standard Rooftop Mounting Structure is the most common choice of many households. These are the most basic mounting structures that come in three different types.

Railed Mounting Structure: In a railed mounting structure, solar panels are fixed on several rails through a set of clamps. The rails are made of Galvanized Iron and attach to your roof by using a drill and nut-bolts.

Ballast Type Mounting System: Rail less mounting structure is also known as ballasted mounting structure. In this structure, solar panels are directly fixed with the roof by using hardware. This is a cost effective and easy way to install solar panels on roofs.

Ballast type solar module mounting structure is a type of mounting system in which the panels are secured to the roof of a building using heavy weights, such as concrete blocks, to prevent them from moving.

This type of structure does not require any direct attachment to the roof, which makes it suitable for use on roofs that are unable to support the weight of other types of mounting systems, or where there is a need to avoid penetrating the roof. Ballast type mounting systems are also relatively simple to install and can be easily adjusted to accommodate changing conditions, such as wind or snow loads. However, they do require regular maintenance to ensure that the weights remain in place and the panels remain secure.

Elevated Rooftop Solar Module Mounting Structure

In elevated solar panel structure, solar panels are installed at a height of 10 to 15 ft. There will be a little room type space beneath the mounting structure. It is also the most common type of mounting structure.

An elevated rooftop solar module mounting structure refers to a type of rooftop-mounted system, in which the solar panels are mounted on a framework that is elevated above the roof of the building. This type of structure provides a number of benefits, including increased airflow under the panels for improved cooling and reduced wind resistance, as well as improved access for maintenance and cleaning.

The elevated structure typically consists of a series of poles, rails, and brackets that are attached to the roof, with the solar panels mounted on top. This type of mounting structure is often used in industrial or commercial applications, where there is a large roof area available for solar panel installation.

How to Select RCC Rooftop Solar Structure ?

Pre-galvanized and hot-dip galvanized are two different methods of coating steel components to protect them from corrosion. In the context of solar module mounting structures, these coatings are used to protect the steel frames, rails, and other components from rust and other forms of corrosion caused by exposure to the elements.

  1. Pre-galvanized: In this process, the steel components are coated with a layer of zinc prior to fabrication, which provides a protective barrier against corrosion. This method is relatively quick and inexpensive, but the zinc coating is not as thick or durable as that produced by hot-dip galvanizing.

  2. Hot-dip galvanized: In this process, the steel components are immersed in a bath of molten zinc, which provides a much thicker and more durable coating. Hot-dip galvanizing is more expensive than pre-galvanizing, but it provides better protection against corrosion and is generally considered to be a more durable option for use in harsh environments.

When choosing a solar module mounting structure, the type of galvanization used should be considered based on the local climate and the expected lifespan of the system. Hot-dip galvanized structures are generally recommended for use in areas with harsh weather conditions, while pre-galvanized structures may be suitable for use in more temperate climates. Selection of right Solar Installer will help you in getting right Solar Module Mounting structure Installed on building rooftop.

Industrial Shed Rooftop Module Mounting Structure

An industrial shed rooftop module mounting structure refers to the framework or support system used to mount and secure solar panels or other modules on the roof of an industrial shed. This structure typically consists of aluminum or steel frames, mounting rails, clamps, and brackets, which are used to attach the modules to the roof and keep them in place. These type of structures are suitable for Solar Industrial rooftop ongrid solar system Installation.

The purpose of the structure is to provide a stable and secure platform for the solar panels, while also allowing for ease of maintenance and installation. Tin shed solar structures are the cheapest of all types of solar mounting structures.

Ground Mounted Module Mounting Structure

In a ground mounting solar system, the solar panels are installed on ground. The land where the solar structure is getting installed could be parks, playgrounds, agricultural land, etc.

There are three types of ground mounting solar structure as mentioned below.

Foundation Mounting Structure: This is the most common type of ground mounting structure. In this system, land will be excavated to put the vertical pipes surrounded by a concrete foundation. The land is strong enough to hold the mounting structure or not, it finalizes after the site analysis by the Solar experts.

Ballasted Mounting Structure: In ballasted solar mounting structures, precast concrete block anchors will be used. Your solar structure will be fixed by using cementing materials.

Pole Mounting Structure: Ideal for a small solar system, especially for residential purposes, the pole mounting structure functions on a simple foundation that is pole:

  • Single Pole Mounting Structure: In a single pole mounting system, a simple steel pole with a concrete anchor will be fixed on the ground. The solar panels will be installed on this pole.

  • Multi Pole Mounting Structure: In a multi pole mounting structure, a number of poles are used in a single horizontal line. The solar panels will be installed on these poles.

Advantages of Right Solar Module Mounting Structure

  • Increase efficiency : Mounting structures play an important role in determining the overall efficiency of the solar system, both rooftop and utility. They lift the PV modules at suitable angles and assure maximum energy generation by tilting the solar panels.

  • Provide Support and Protection : Mounting structures bear the entire weight of the solar panels. They help the Solar panels to rest comfortably and work productively. Solar mounting structures protect the solar panels from being damaged.

  • Strong and Durable : Solar mounting structures are strong and durable to withstand extreme weather conditions. They are responsible for providing the solar system with an increased life expectancy.

  • Available in many different forms : They are available in a variety of materialistic forms including steel, aluminium, etc. The material they are made of assures you that they are highly durable, corrosion-resistant and rust-free.

  • Attract technological innovations : Mounting structure technologies are developing rapidly. As a result, there is a reduction in the cost of the structure. Also, the installation process has become easier and faster. Besides, with technological innovations, the mounting structures are becoming more durable and productive.
