The CORAB PB-94 is a mounting system designed for photovoltaic modules, primarily for flat roofs. It is a robust and versatile solution, engineered to provide a secure and efficient installation for solar panels, ensuring optimal performance and longevity.

Function Description

The primary function of the CORAB PB-94 system is to securely mount photovoltaic modules on flat roofs, orienting them at an optimal angle for maximum solar energy capture. The system is designed to create a stable and durable structure that can withstand various environmental conditions, including wind loads and snow. It facilitates the creation of both single-row and multi-row solar installations, offering flexibility in design and scalability for different project sizes. The system ensures proper ventilation for the modules, which is crucial for maintaining their efficiency and preventing overheating.

Important Technical Specifications

The CORAB PB-94 system is designed for a flat roof installation with a module tilt angle of 15 degrees. It is suitable for modules with a width of 1000mm. The system components are manufactured from high-quality materials, primarily aluminum, ensuring durability and resistance to corrosion.

Key components include:

Mounting Brackets (XPF_PB094.1.001): These are the primary structural elements that support the modules and provide the tilt angle. They are designed for easy assembly and secure attachment. The system includes 10 pieces of these brackets per module layout.
Wind Deflectors/Windchests (XPF_PB068.5.001A): These components are crucial for managing wind loads, protecting the modules, and enhancing the aerodynamic stability of the entire installation. The system includes 8 pieces of these per module layout.
Clamps (M950): These are used to secure the modules to the mounting structure. They are designed for quick and easy installation. The system includes 32 pieces of these.
Screws and Nuts (M485, M935, M484, M529): Various types of screws and nuts (M8x20 DIN912, M8 DIN7980, M8 DIN125, 6x25 A2 + EPDM) are provided for assembling the different components of the system. The quantities are specified for each type to ensure a complete assembly.
Tools: The installation requires standard tools such as a screwdriver/drill and an 8mm wrench.

The system is certified by TÜV Rheinland, indicating compliance with international quality and safety standards. It also holds a CE mark, confirming its conformity with European health, safety, and environmental protection standards.

Usage Features

The CORAB PB-94 system offers several usage features that make it a practical choice for photovoltaic installations:

Ease of Installation: The manual emphasizes a straightforward assembly process. Components are designed for quick and intuitive connection, reducing installation time and labor costs. The step-by-step instructions, accompanied by clear diagrams, guide installers through each stage, from assembling the main brackets to securing the modules.
Modular Design: The system's modular nature allows for flexible configuration. It can be adapted to various roof dimensions and project requirements, enabling the creation of both small-scale and large-scale solar arrays. The ability to combine multiple modules into rows simplifies planning and execution.
Optimized Tilt Angle: The fixed 15-degree tilt angle is chosen to maximize solar energy capture in many geographical locations, especially in regions where a moderate tilt is beneficial for year-round performance.
Aerodynamic Stability: The inclusion of wind deflectors is a key feature, significantly improving the system's resistance to wind uplift and shear forces. This design aspect is critical for the long-term safety and stability of the installation, particularly on exposed flat roofs.
Compatibility: The system is designed to be compatible with standard PV modules, specifically those with a width of 1000mm. This broad compatibility ensures that installers can choose from a wide range of available modules.
Robust Construction: The use of high-quality aluminum components ensures the system's durability and resistance to harsh weather conditions, including UV radiation, temperature fluctuations, and moisture. This contributes to a long service life for the entire PV installation.
Flexible Module Attachment: The system allows for module attachment using standard clamps or M8 nuts with hex rivnuts, providing options for installers based on their preferences and specific module types.

Maintenance Features

The CORAB PB-94 system is designed for minimal maintenance, focusing on durability and long-term reliability:

Corrosion Resistance: The primary use of aluminum components ensures excellent resistance to corrosion, which is crucial for outdoor installations exposed to varying weather conditions. This minimizes the need for rust-related maintenance.
Durable Fasteners: The use of specified screws and nuts, including those with EPDM washers, helps create secure and weather-resistant connections, reducing the likelihood of loosening or material degradation over time.
Self-Cleaning Design: The 15-degree tilt angle can aid in the natural self-cleaning of the modules by rainwater, helping to wash away dust and debris. This can reduce the frequency of manual cleaning required to maintain optimal module performance.
Accessibility for Inspection: While the system is robust, its design allows for relatively easy access to components for periodic inspections. This enables installers or maintenance personnel to check the integrity of connections, the condition of the modules, and the overall stability of the array.
Component Replacement: In the unlikely event of damage to a specific component, the modular design facilitates the replacement of individual parts without needing to dismantle the entire system, simplifying repairs and extending the life of the installation.

The CORAB PB-94 system is a comprehensive and reliable solution for mounting photovoltaic modules on flat roofs, combining ease of installation with robust construction and features designed for long-term performance and minimal maintenance.
