1. Proprietary Glass-to-Metal Sealing
Holding over 60% market share. Our proprietary sealing process withstands thermal shocks from -50°C to 550°C, ensuring the vacuum integrity of the receiver tube for over 30 years.
2. High-Transmittance AR Coating
Cover tube solar transmittance ≥96% with a 6.5H hardness. It performs excellently in acid salt spray and damp heat tests, delivering 3.5% higher efficiency than industry standards.
3. Advanced High-Vacuum Coating
Absorptance (α) ≥0.955 and emittance (ε) ≤0.05 (at 100°C). This significantly reduces convective and radiative heat loss, enabling high-efficiency collection in all weather conditions.4. Precision Smart Tracking System
Features a tracking accuracy of ≤0.1°. Equipped with automatic wind protection, the system resets during extreme weather (high winds/snow), increasing overall system efficiency by 2%.| Parameter | Value |
| Operating Temperature | 80°C - 550°C |
| Photothermal Efficiency | 3.5x higher than PV |
| Collector Aperture | 5.7m / 6.0m (Optional) |
| Vacuum Level | ≤ 5.0×10⁻⁵ Pa |
| Reflectivity | ≥ 94% (Low-iron tempered silver mirrors) |
| Design Life | 30 Years (Efficiency no recession) |
Low Temp (40-80°C): Municipal heating, hotel hot water systems, and swimming pool heating.
Medium Temp (80-260°C): Industrial process steam for textiles, food, chemicals, and timber drying.
High Temp (>260°C): Concentrated Solar Power (CSP) and solar-driven desalination.
Based on Life Cycle Cost (LCC) analysis over 30 years, the total cost of this system (including installation and maintenance) is only 1/5 of natural gas and 1/10 of electric heating systems. The typical payback period is 3-5 years.
