Best Solar Panel Mounting Rails in the UK – 2023

Last updated: February 13th, 2024 at 04:25 am

Solar panel mounting rail is a compulsory component of solar PV system installations as they securely hold the solar panels in place on rooftops or ground-mounted structures. Almost every solar panel mounting structure is lightweight, durable, and weather-resistant. They are designed to make solar panel installation easy and ensure optimal panel alignment, maximizing energy production while providing long-lasting support for sustainable power solutions.

Solar mounting rails come in different designs and sizes. But the primary purpose of all these rails is to securely hold the panels while maintaining their alignment.

Key Notes

• Solar panel mounting rails are the most common type of mounting system for rooftop solar panels. They are made of aluminum or steel and are designed to be strong and durable.
• The cost of solar panel mounting rails typically accounts for about 10% of the total cost of a solar system.
• Solar panel mounting rails are available in a variety of sizes and styles to accommodate different roof types and solar panel configurations.
• Solar panel mounting rails are typically made of corrosion-resistant materials to withstand the elements.

What Are Solar Panel Mounting Rails? 

When considering solar panel installation, solar panel rails play an essential role in ensuring a proper and efficient system setup. They serve as the foundational framework onto which solar panels are securely attached, facilitating the optimal positioning of panels to capture sunlight efficiently.

Solar mounting rails are available in various sizes and configurations to accommodate different solar panel sizes and installation types. Typically constructed from materials such as aluminum or steel, they ensure longevity and resistance to environmental factors.

What Are the Benefits of Using Solar Panel Mounting Rails?

Solar panel mounting rails are the structures that support solar panels on roofs or on the ground. They come in a variety of materials, styles, and sizes, and are designed to withstand the weight of the solar panels, as well as the wind and snow loads in your area.

Some of The Benefits of Using Solar Panel Mounting Rail

Flexibility

 Solar panel mounting rail can be adjusted to accommodate different roof pitches and styles, as well as different sizes and types of solar panels. This makes them a versatile option for a variety of solar installations.

Durability

Solar mounting rails are made from strong materials that can withstand the elements. This ensures that your solar panels will be secure and protected from damage, even in harsh weather conditions.

Ease of installation

Solar panel mounting rails are relatively easy to install, even for DIYers. This can save you money on installation costs.

Long lifespan 

Solar panel mounting rails are designed to last for many years. This means that you won’t have to worry about replacing them often.

Safety

Solar panel mounting rails are designed to keep solar panels secure and prevent them from falling. This is important for safety, as well as for the performance of your solar system.

Types of Solar Panel Mounting Rails in the UK

Solar mounting rails come in various design, materials and sizes, and their prices vary depending on your choice of material and size. However, here are the most frequently used solar panel mounting rail in the UK:

Fixed-Tilt Mounting Rails

Fixed tilt mounting rails are the most common type of mounting rail for solar panels. They are attached to the roof and the solar panels are mounted to the rails in a fixed position. The tilt angle of the rails is typically set to the optimal angle for the location, which is usually between 15 and 30 degrees.

Fixed tilt mounting rails are relatively inexpensive and easy to install. They are also a good option for roofs with a limited pitch. However, they are not as efficient as adjustable-tilt or tracker mounting rails, which can track the sun’s movement throughout the day to maximize solar energy production.

Adjustable-Tilt Mounting Rails

Adjustable-tilt mounting rails are a type of mounting rail that allows the solar panels to be tilted to different angles. This allows the solar panels to be optimized for the time of year and the location of the roof. Adjustable-tilt mounting rails are a good option for roofs with a limited pitch or for roofs that are facing north or south. Adjustable-tilt mounting rails can increase solar energy production by up to 20% compared to fixed tilt mounting rails.

Tracker Mounting Rails

Tracker solar panel mounting rails are a type of mounting rail that tracks the sun’s movement throughout the day to keep the solar panels facing the sun. This allows the solar panels to collect the maximum amount of solar energy possible. Tracker mounting rails are the most efficient type of mounting rail, but they are also the most expensive.

How Are Solar Panels Attached to Rails?

Solar panels are attached to rails using a combination of mounting hardware and brackets. Here’s a basic overview of the process.

Solar Panel Frame

Solar panels typically have an aluminum frame around their edges. These frames are designed with mounting holes or channels that allow for easy attachment to mounting rails.

Mounting Rails

Mounting rails are installed on the mounting structure, which could be a rooftop or ground-mounted structure. These rails run horizontally and provide a stable framework for securing the solar panels.

Clamps or Brackets

Specialized clamps or brackets are used to secure the solar panels to the mounting rails. These clamps or brackets are typically adjustable to accommodate various panel sizes and frame dimensions.

Positioning

Installers carefully position the solar panels on the rails, ensuring they are correctly aligned and spaced for optimal sunlight exposure.

Attachment

The clamps or brackets are then attached to the mounting rails and the solar panel frame. This step requires a certified and experienced installer to ensure the secure fitting of the solar panels.

Tightening

The clamps or brackets are tightened to secure the panels firmly in place. It’s essential not to over-tighten, as this could damage the panels or the mounting structure.

Final Inspection

Installers conduct a final inspection to ensure that all panels are securely attached and correctly positioned. They also check the wiring for safety and functionality. 

What Is the Spacing for Solar Rail Mount?

To ensure optimal solar panel installation, it’s crucial to maintain the correct spacing between the mounting rails. Ideally, the distance between the rails should be approximately three-quarters of the panel’s height. This spacing ensures proper support and stability for the panels, allowing them to securely capture sunlight and generate energy efficiently. Precise rail placement, guided by certified installers, plays a key role in maximizing the effectiveness and longevity of solar panel systems.

Summary  

Solar panel mounting rails are an essential part of solar panel installations, as without them, solar panels cannot be securely positioned to generate efficient power. There are three main types of solar panel mounting rails: Fixed-Tilt Mounting Rails, Adjustable-Tilt Mounting Rails, and Tracker Mounting Rails. Among these, fixed-tilt mounting rails are the most commonly used due to their affordability and durability. Conversely, the most efficient rails are tracker mounting rails, they come at a higher cost, offering the potential to generate up to 30% more electricity compared to other mounting rail types.
