Product catalog summary
Introduction
The document describes the manufacturing and technical specifications of a mirror panel system designed for solar applications. The system combines a mirror surface with a rigid composite panel structure, incorporating a corrosion-resistant aluminum sheet.

Material and Design
The mirror panel is designed to have a uniform thermal coefficient of expansion, minimizing temperature effects on shape stability. It is lightweight and has high stiffness, simplifying construction and reducing costs. The panel's shape and dimensions can be customized to meet specific customer requirements.

Technical Characteristics
The panel structure, reflector size, and curvature are adjustable. The reflectors have exceptional flexural rigidity, allowing them to resist high loads without deformation. This reduces the complexity and weight of the mechanical support structure.

Mounting
The panels can be mounted easily with fewer points due to their light weight and high rigidity. They can be attached using conventional methods or directly to a support frame without affecting reflective performance.

Mirror Surface
The mirror surface is made of high-purity aluminum with a PVD applied reflection enhancing system, achieving over 95% reflectance. It is protected by a weather-resistant top coat.

Durability and Performance
The panels are designed for long-term high reflectivity performance, with a guarantee of maintaining reflectance within 3% of the original value for 10 years. They are also 100% recyclable.

Physical Properties
The document provides detailed physical properties, including specific weight, stiffness, impact resistance, thermal expansion, and surface hardness.

Applications
The panels are suitable for solar thermal and photovoltaic electricity generation, solar-powered desalination equipment, heat pump air conditioning systems, and thermal fluids for industrial process heating.

Advantages
The system offers advantages such as design flexibility, robustness, durability, recyclability, and ease of installation. It is also noted for its improved wind resistance and reduced maintenance costs.

Conclusion
The document highlights the innovative design and efficiency of the mirror panel system, emphasizing its suitability for various solar applications and its economic and environmental benefits.

advantages Simplicity Large scale modular structure Installation Design flexibility Mirrors are supplied complete with rigid backing shaped to customers’ specification. Thanks to their unique production technology, single element curved mirrors can be produced with apertures up to 6500 mm. Light weight (about 50% compared with traditional solutions) and robust mechanical properties result in easier and more economical installation with low breakage losses during assembly. parabolic mirrors can be supplied with small concentrating apertures for ‘micro’ installations and with radius of curvature...
