Tilted mounting structures

Mounting systems are a crucial component in solar technology, ensuring that photovoltaic or solar modules are positioned at an optimal angle to the sun. This technology is frequently used on flat roofs, open spaces, and even pitched roofs to maximize the energy efficiency and performance of the solar system. This article will tell you everything you need to know about mounting systems, how they work, their advantages, and their applications.

What is a raised platform?

A mounting system is a structure that positions solar modules at a specific angle above a surface. It consists of a stable frame that supports and aligns the modules. The structure can be permanently installed or flexibly adaptable, depending on the project requirements.

How a mounting system works

The main purpose of a mounting system is to align the solar panels at an optimal angle to the sun. This ensures that the panels capture as much sunlight as possible. Important factors include:

• Tilt angle: The optimal tilt angle depends on the geographical location and in Central Europe is usually between 30° and 40°.
• Orientation: Ideally, the modules should be oriented towards the south to maximize solar radiation.
• Weather resistance: The mounting structure must be stable enough to withstand wind loads, snowfall and other weather conditions.

Types of mounting systems

There are different types of mounting systems, each suitable for different applications:

1. Fixed mounting

A fixed mounting system has a fixed tilt angle and is particularly cost-effective. It is suitable for projects where the modules can remain permanently in an optimal position.

2. Adjustable stand

Adjustable mounting brackets allow the tilt angle to be adjusted according to the season or weather conditions in order to maximize energy yield.

3. Tracking systems

These systems automatically move the modules to follow the sun's position. Tracking systems offer the highest energy efficiency but are more expensive and require more maintenance.

Advantages of a raised mounting system

Using a mounting system offers numerous advantages, especially for solar installations on flat roofs or open spaces:

1. Maximum energy yield

By optimally aligning the solar modules, the yield of the system can be significantly increased.

2. Flexibility

Mounting systems enable the use of solar modules on surfaces that could not be used without this technology, such as flat roofs or open spaces.

3. Module protection

The structure lifts the modules and protects them from dirt, water accumulation, or other harmful influences.

4. Reduced shading

The modules are positioned so that they do not shade each other, which increases the efficiency of the entire system.

Application areas of the mounting system

Mounting brackets are used in various areas:

• Flat roofs: Particularly suitable for buildings with flat roofs where there is no natural slope.
• Open spaces: On large open areas, elevated structures enable the efficient use of the available space.
• Commercial installations: Companies often rely on mounting systems to meet their energy needs through solar installations.

Materials for mounting structures

The structure of a mounting frame must be stable and weatherproof. Commonly used materials include:

• Aluminum: Lightweight, corrosion-resistant and durable.
• Steel: Particularly robust, but susceptible to corrosion if not specially treated.
• Plastic: Used less frequently, but is lightweight and inexpensive for smaller projects.

Challenges and solutions

Installing a mounting system can present some challenges:

• Wind loads: On flat roofs or open areas, the structure must be strong enough to withstand high wind speeds.
• Statics: The roof or the substrate must be able to support the weight of the mounting system and the solar modules.
• Costs: Mounting systems can increase the overall cost of a solar power system. However, the long-term increases in yield often offset these costs.

Conclusion: The importance of the mounting system

Mounting systems are an essential component for solar power installations, especially on flat roofs or open land. They ensure optimal alignment of the solar modules, increase energy efficiency, and offer flexible deployment options. With proper planning and high-quality materials, mounting systems represent a sustainable and worthwhile investment in renewable energy.
