What are the advantages of vacuum tubes over solar panels
Advantage of Evacuated Tube Solar Collector based systems over Solar Panel Collectors:
- Larger surface area exposed to the sun at any time due to round structure
- Efficient in heat absorbance: 50%
- Frost tolerant and can be used in sub-zero temperatures
- Strong and durable with 25mm hail rating
- Provide excellent performance in overcast conditions
- Require a smaller roof area than comparable flat plate collectors
- Install with pressurised storage tanks
- Replace flat panels
- Modular
