Evacuated Tube VS Flat Panel
Evacuated Tube VS Flat Panel
What is Evacuated Tube and what is Flat Panel?
Both are solar heating collector, and their job is simple; it sits in the sun, absorbs the heat, and transfers it to where you need it. To do this efficiently, solar heating collectors need to absorb – and retain – a large volume of sunlight every day. Now you know the function of solar heating collector, so lets take a look at the main comparison.

Smart Solar Evacuated Tube System
Flat Panel System
1. Health
Close Loop
- Water Don’t Pass through Solar Collector
- Healthy Hot Water
Open Loop
- Water Pass through Solar Collector
- Copper Corrosion
- Copper toxicity
Active Protection
Magnesium Rod use as anode rod to maximize anti-rust protection to prolong the lifespan.
No Protection
No such feature.
2. Longevity
316L Marine Grade Stainless Steel
Marine Grade Stainless Steel that have high resistance and protection in corrosion.
304 Normal Stainless Steel
Normal Grade Stainless Steel
Leaking Protection
No Pipe Fitting connect the tank and the evacuated tube. Therefore, the chance of water leakage is virtually zero.
Possible Leaking Issue
There are Copper Compression Fitting connect the pipe between flat plat and tank. Thermal expansion and contraction at outdoor environment will cause leak issue.
3. Efficiency
High Heat Retain
High Heat Retain, the vacuum state between inner and outer layer glass create ``Thermos Effect``.
Low Heat Retain
Heat loss due to uninsulated between copper plate and glass in Heat Plate panel.
Most Efficient System
Water Temperature can reach over 90°C in sunny day, cloudy day can reach 40-50°C. High efficiency 360° CPC sunlight collector booster.
Old System
Only 50-60°C in sunny day, during cloudy day need electric heater to assist. Less Effective because sunlight only hit Flat Surface.
4. Smart
Smart Heater Control
Auto Switch on Heater when the temperature below set point and auto switch off when the temperature above set point.
Manual Switch
Need manual switch on when there is no hot water. Forgot to close may cost a bomb to your electric bill!
Smart Temperature Display
Tank equip with temperature sensor. You can clearly know what is the temperature inside your tank.
No Such Feature
Don't have sensor.
