Mounting for solar panels

A proper mounting system is not just an auxiliary component but an essential part of the reliability of a solar power plant. Poor-quality solar panel mounting hardware may fail under snow loads or strong wind gusts. The Altek catalog features solar panel mounting systems made of aluminum profiles and galvanized steel for all roof types and ground-mounted installations. Every solar panel mounting solution is designed for a service life of at least 25 years.

Solar Panel Mounting Systems: Types and Features

The design of a mounting system depends on the type of base structure. Altek offers several product lines of solar panel mounting hardware.

• Aluminum rails – the foundation of any mounting system. Length is selected according to panel dimensions and roof rafter spacing. Anodized aluminum is corrosion-resistant and can withstand loads for more than 30 years.
• End clamps and mid clamps – secure panels to the rails. End clamps are installed at the edges of a row, while mid clamps are placed between panels. Materials: aluminum or galvanized steel.
• Mounting hooks and plates – used to attach rails to pitched-roof rafters. Selected according to rafter spacing and roof tile profile.
• Anchoring systems for flat roofs – ballast-mounted (without roof penetrations) or adhesive solutions. The tilt angle is adjusted using adjustable supports.
• Ground-mounted structures – pile-driven or screw foundation systems with adjustable tilt angles for solar power plants installed on open sites.

Solar Panel Installation: Mounting Systems

A solar panel mounting system is designed for a specific project, considering roof type, orientation, and regional wind and snow loads. Altek supplies mounting solutions for:

• Pitched roofs – tile, metal tile, corrugated sheet metal, and standing seam roofs. Each roofing material requires its own type of hook or clamp.
• Flat roofs with membrane or concrete foundations – ballast-mounted frames that preserve waterproofing integrity.
• Facades – vertical mounting for BIPV systems (Building-Integrated Photovoltaics).
• Ground installations – support structures for ground-mounted solar power plants starting from 10 kW.

All system components are compatible with one another. Rail widths and clamp sizes are designed for standard 60-cell and 72-cell solar panel formats.

Solar Panel Mounts for Roofs and Ground Installations

The most popular items in the solar panel mounting catalog include:

• ALTEK 35 mm end clamp – a universal solution suitable for most panels with frame thicknesses of 30–40 mm.
• ALTEK T-shaped mid clamp – designed for paired panel rows, made of aluminum/zinc-coated materials.
• M10×200 galvanized hanger bolt – used for fastening rails to wooden rafters.
• ALTEK M8 special nut with plastic retainer – connects clamps to rails without rotation during installation.

All fasteners are galvanized or made of stainless steel. Their service life in outdoor conditions is at least 25 years, matching the warranty period of solar panels.

How to Choose Solar Panel Mounting Hardware

Four steps to selecting the right mounting system:

• Determine the type of roof or base structure: pitched roof, flat roof, facade, or ground installation. Specify the rafter spacing and roofing material, as these determine the required hook type.
• Measure the width of your panel frame, as this determines the clamp size.
• Calculate the required number of rails: one rail per panel row, with length equal to the total panel width plus spacing gaps.
• If you need assistance with system configuration calculations, Altek managers will help select all required solar panel mounting components and frame hardware based on your specifications.
