Selecting suitable materials is important when constructing reliable solar panel systems and switchgear.
This article explores a wide range of reasons why steel is essential for solar panels and switch gear, the types of steel used, and why Baldwins Metal Land is THE steel supplier for your solar panel and switch gear frames.
The Impact of Tariff Hikes SA’s Solar Industry
The solar industry has taken off due to skyrocketing electricity costs and Eskom’s numerous tariff hike requests. As recently as September 2024, Eskom sought a 36% increase in electricity tariffs from NERSA (National Energy Regulator of South Africa). With potential price hikes like this, investing in durable solar panels has become imperative for businesses looking to manage escalating energy costs.
Why Steel is Essential for Solar Panels and Switch Gear?
The steel structures are designed to endure the harshest environments. That is why steel is critical in solar energy and electrical systems.
Steel is used in solar panel mounting systems, frames, and support structures to stabilise and withstand harsh weather conditions.
Switchgear consists of multiple switching devices that control and isolate power systems. Switchgear plays a big part in managing electrical circuits and ensuring the safe distribution of electricity.
Steel plays a crucial role in the need for reliable electrical distribution and the rise of renewable energy initiatives.
The need for steel has resulted in an increasing demand for trusted suppliers like Baldwins Metal Land to provide high-quality steel solutions that meet the needs of the solar energy and electrical sectors in South Africa.
Steel’s Role in the Building of Core Parts of Steel Products
Mounting Structures for Solar Panels:
The mounting structure is one of the most critical elements of a solar power system. Galvanised steel frames support solar panels, securing them in place and positioning them correctly to maximise sunlight exposure.
The strength steel provides helps these structures withstand strong winds and other environmental challenges, enhancing the longevity of the solar panels.
Frames and Racks:
Steel is used in the frames and racks holding individual solar panels and mounting structures. These components must be lightweight yet strong enough to provide support without adding excessive weight to the installation.
Using steel ensures a balance between stability and manageability, making it the preferred choice.
Enclosures and Casings for Switchgear:
Switchgear systems require durable enclosures and are essential for controlling, protecting, and isolating electrical equipment. Steel casings are commonly used to protect these components from physical damage, moisture, and other environmental factors.
Steel’s strength ensures the safety and reliability of switch gear systems, which are often exposed to high levels of electrical stress.
The Types of Steel Used in Solar Panels and Switchgear
Different types of steel excel in specific environments. Choosing the correct steel that aligns with the demands of solar panel installations and switchgear production can make all the difference. Below are some of the common types:
- Galvanised Steel
This is a top choice for solar panel mounting systems because it offers excellent resistance to rust and corrosion, which is crucial for outdoor applications exposed to the elements.
- Stainless Steel
Stainless steel is designed to provide durability and high resistance to extreme temperatures; it is ideal for switchgear components facing high electrical and thermal stress.
- Carbon Steel
Often used in support structures, carbon steel provides the necessary strength at a lower cost, making it an economical option for large-scale projects.
The Benefits of Steel in Solar Panels and Switch Gear
Using steel in the construction of solar panels as well as switch gear offers numerous benefits, making it the material of choice for manufacturers and engineers:
Tensile Strength:
Steel’s high tensile strength allows it to withstand significant loads and stresses, making it ideal for the demanding environments of solar farms and electrical systems. It can endure harsh weather, including strong winds and heavy rain, without compromising structural integrity.
Corrosion Resistance:
Galvanised and stainless steels provide excellent corrosion resistance, which is essential for outdoor installations exposed to the elements. This resistance helps extend the lifespan of solar panel mounting systems and switch gear housings by reducing maintenance costs and ensuring long-term reliability.
Affordability:
Steel is an affordable material that offers a great balance of strength and cost. Its availability and ease of fabrication make it a cost-effective solution for large-scale installations, such as solar farms and electrical distribution networks.
Recyclability:
One of the significant environmental benefits of steel is its recyclability. Steel can be recycled multiple times without losing its properties. Thus, it is the best eco-friendly choice for sustainable energy projects. This aligns with the growing emphasis on green construction practices in South Africa’s renewable energy sector.
