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.
