Esdec Solar Mounting Systems UK — ClickFit Evo & FlatFix Fusion

Why UK Installers Trust Esdec for Solar Mounting, FlatFix Fusion & ClickFit Evo Explained

When it comes to solar mounting systems in the UK, precision and reliability are everything. A well-designed frame doesn’t just hold the panels in place, it determines the efficiency, lifespan and safety of the entire system. That’s why professional installers across the country increasingly choose Esdec, one of the world’s leading names in rooftop solar mounting and part of the Enstall Group.

At Evergy, we’re proud to supply Esdec’s full range of ClickFit Evo and FlatFix Fusion components to trade and commercial customers nationwide. From rapid-fit pitched-roof brackets to aerodynamic flat-roof assemblies, these systems help installers deliver faster, cleaner and more compliant solar projects, supported by Esdec’s global engineering expertise and Evergy’s local stock and same-day delivery network.

Global Innovation, Local Expertise

Esdec has been developing advanced solar mounting solutions for more than twenty years, setting benchmarks for simplicity, safety and long-term durability. Now owned by Enstall, the international renewable-technology group behind several market-leading brands, Esdec continues to invest in the tools and research that make life easier for installers.

By partnering with Evergy, UK electricians, solar specialists and renewables contractors gain direct access to Esdec’s trusted hardware with no lengthy lead times or overseas ordering. Every component we stock, from FlatFix Fusion Low Bases to ClickFit Evo brackets, is backed by technical data, installation guidance and Esdec’s long-term product warranty.

Why Mounting Systems Matter

A solar array is only as strong as its foundation. Inferior or improvised mounting can lead to leaks, movement and reduced generation, especially on the diverse roof types found across the UK. Esdec’s engineered approach eliminates guesswork, ensuring every component works together for maximum structural integrity and electrical safety, whether on composite tiles in Oxfordshire or standing-seam metal in industrial London.

In the sections below, we’ll explore how ClickFit Evo streamlines pitched-roof installations, why FlatFix Fusion remains the benchmark for flat-roof projects, and how Evergy supports installers with ready-to-ship stock, expert guidance and dependable trade service.

About Esdec and the Enstall Group

Founded in the Netherlands, Esdec has grown into one of Europe’s most trusted names in solar mounting systems. Its parent company, Enstall, brings together several pioneering renewable technology brands, each focused on making solar deployment faster, safer and more scalable. Together, they combine extensive research, international experience and engineering excellence to support installers from design to delivery.

Esdec’s mission is simple: to make rooftop solar easy. Every product is designed around real-world installation challenges, helping professionals save time on site without compromising quality or compliance. Whether it’s a domestic pitched-roof system in Milton Keynes or a commercial flat-roof array in Birmingham, Esdec products offer the reassurance of tested performance and robust European manufacturing.

Technical Excellence & Independent Certification

Each Esdec system is rigorously tested to meet or exceed international standards. Components are TÜV certified, wind-tunnel tested and corrosion-resistant, ensuring long-term reliability under UK weather conditions. Esdec’s mounting systems are engineered to handle variable roof loads, thermal expansion and high wind uplift, all validated through independent structural testing.

Installers can also rely on Esdec’s extensive 20-year product warranty, demonstrating the brand’s confidence in both materials and design. For professional installers, that level of assurance means fewer callbacks, longer-lasting installations and full peace of mind for their customers.

Continuous Innovation Backed by Data

Esdec’s R&D division works closely with global installation partners to refine every detail, from the geometry of a seam clamp to the airflow across a FlatFix Fusion wind deflector. Their engineers use advanced simulation tools to optimise stability and minimise the amount of ballast or fixings required, leading to lighter, faster and more economical installations.

Because Esdec operates within the wider Enstall network, its designs also benefit from shared insight across global markets, from European urban rooftops to North American commercial buildings, making the products fully proven in varied conditions before they reach UK installers.

ClickFit Evo: The Fast, Reliable Pitched-Roof Mounting System

If you’re fitting solar panels on pitched roofs, the Esdec ClickFit Evo system is designed to make your job faster, cleaner and more consistent. Developed with installers in mind, it removes the fiddly parts of mounting – replacing time-consuming screw fittings with a simple ‘click-and-lock’ mechanism that saves hours on site while maintaining structural precision.

Engineered for Every Roof Type

Whether you’re working on slate, tile, corrugated metal or standing-seam roofs, ClickFit Evo has a dedicated fixing solution that keeps the roof watertight and the array perfectly aligned. The system uses non-penetrative or low-impact brackets and clamps that distribute weight evenly, helping maintain roof warranties while withstanding strong UK wind and weather conditions.

Installers can choose from an extensive range of components, all available from Evergy:

• ClickFit Evo Corrugated Mounting Bracket – for secure fixing through metal or fibre-cement sheeting into the purlins beneath.
• Double Folded Seam Clamp (9 mm) and Round Seam Clamp (23 mm) – non-penetrative clamping solutions for standing-seam metal roofs.
• ClickFit Evo Mounting Rail (3488 mm) – a high-strength aluminium rail that forms the backbone of the system.
• Universal Module Clamp (Grey) – fits most panel heights and clicks straight into place for rapid alignment.

Speed Without Compromise

ClickFit Evo’s hallmark is speed – installers routinely report time savings of up to 40 per cent compared with traditional systems. Each part connects intuitively, reducing the need for special tools or multiple component types on site. The result is fewer potential errors, cleaner wiring routes and a more professional-looking finish.

Strength Tested for UK Conditions

All Esdec ClickFit Evo components are independently tested to meet structural and environmental standards for use in the UK. The system has been TÜV-certified for strength and corrosion resistance, with load testing conducted to account for regional snow and wind zones. For installers, that means every project can be specified confidently using the Enstall Calculator for Esdec – generating precise layouts, fixings and ballast requirements.

Why Installers Choose ClickFit Evo

• Time efficiency: Click-in design dramatically shortens fitting time.
• Compatibility: Options for tiled, metal and standing-seam roofs.
• Reliability: Non-penetrative fixings maintain roof integrity and warranty.
• Professional results: Sleek, consistent alignment and easy cable management.

For professional installers across the UK, ClickFit Evo represents the perfect balance between efficiency, reliability and safety. It’s a system built to work as hard as you do.

FlatFix Fusion: The Proven Flat-Roof Mounting System for UK Installers

For commercial and residential flat roofs alike, Esdec FlatFix Fusion has become the installer’s benchmark for speed, strength and precision. Its modular design, aerodynamic wind-deflector system and intelligent ballast placement make it a market-leading choice for long-term performance, perfectly suited to the varied weather conditions seen across the UK.

Modular Design for Any Flat-Roof Layout

At the heart of FlatFix Fusion is its flexible, click-together architecture. Components such as the Low Base, High Base and Base Profile (1077 mm) combine to create a stable, non-penetrating frame that can be adapted to a wide range of roof sizes and surface types. Installers appreciate the simplicity, each section clicks together neatly, with no need for on-site cutting or drilling.

• Lightweight & strong: Composite and aluminium materials reduce roof load without sacrificing strength.
• Flexible layout: Works for single-row or dual-row designs, in portrait or landscape orientation.
• No roof penetrations: Ballast and aerodynamic design eliminate the need for fixings on most installations.

Engineered Aerodynamics for Wind Resistance

Each installation’s stability depends on airflow control. FlatFix Fusion uses integrated wind-deflectors and stabilisers to manage uplift efficiently, often reducing ballast weight by up to 25 per cent compared with conventional systems.

• Rear Wind Deflector (1700 mm Black) – directs air over the array to lower uplift pressure.
• Left and Right Deflectors – protect the array flanks for full perimeter aerodynamics.
• Stabilizer 1700 – connects bases to increase rigidity across long rows.

The aerodynamic structure has been tested in wind tunnels to meet or exceed UK Building Regulations for solar mounting systems, providing installers and clients with total peace of mind.

Ballast & Load Management

Rather than drilling through membranes, the system uses dedicated ballast trays to secure the structure. The FlatFix Fusion Ballast Container (1700) holds standard paving slabs or equivalent material, spreading weight evenly and protecting the roof surface. For roofs with limited capacity, ballast requirements can be refined using the Enstall Calculator for Esdec, which precisely determines load per m² based on height, zone and panel size.

Additional components such as the Fusion Mat for TPO provide further membrane protection where required, ensuring a compliant and watertight installation.

Installer-Focused Efficiency

Every element of the FlatFix Fusion range has been designed with ease of handling in mind. Parts are lightweight and colour-coded for rapid identification, while clips and couplers ensure consistent alignment across long rows. The MLPE Clip – Light Weight allows tidy mounting of micro-inverters and optimisers, keeping cables organised and protected beneath the panels. The result is a faster, safer and tidier build process that saves valuable time on site.

Trusted Durability and Warranty

As with all Esdec systems, FlatFix Fusion components are manufactured from high-grade, UV-resistant materials and are backed by a 20-year manufacturer’s warranty. For installers, that means confidence not only in performance but also in long-term reliability, reducing call-backs and maintenance.
