BEFORE YOU BUY
Do you know there are 2 TYPES of Solar Hot Water System?
1. Flat Panel System
- Copper Pipe Solar Collector
- Open Loop (Water pass through the solar collector)
- Harm Your Health
- SS304 Stainless Steel
- For Slope Roof Only
2. Evacuated HEAT TUBE System
- Active Heat Tube Collector
- Close Loop (Water won’t pass through the solar collector)
- Healthy Hot Water
- SS316L Stainless Steel
- For Flat Roof and Slope Roof
Sunlight Absorbing Efficiency
*Maximum Heating Power when surface perpendicular with Sunlight.
Reflected Sunlight
Peak efficiency only on noon time.
Passive Sunlight Tracking
Peak Efficiency every hour at day time.
Angel of Absorbing
One-Way Angle
Less surface area to absorb sunlight.
360° Absorbing Angle
• Absorbing surface area is bigger than flat panel.
• CPC reflecting sunlight at every angle.
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.
The Comparison
Smart Solar Evacuated Tube System | Flat Panel System |
|---|---|
 |  |
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 ProtectionMagnesium Rod use as anode rod to maximize anti-rust protection to prolong the lifespan. | No ProtectionNo such feature. |
Longevity
316L Marine Grade Stainless SteelMarine Grade Stainless Steel that have high resistance and protection in corrosion. | 304 Normal Stainless SteelNormal Grade Stainless Steel |
Leaking ProtectionNo 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. |
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. |
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. |
How to Choose the Right One?
3 Things to Consider Before You Buy Solar Hot Water System
WHY MUST
HEALTHY?
Do you know Copper Poisoning? Hot water that contact with copper pipe will cause copper contamination.
WHY MUST
EFFICIENCY?
Different Solar Hot Water System will have different efficiency. Higher efficiency will produce more hot water.
WHY MUST
SMART?
How can you know the temperature inside your tank? Do you have a Smart Panel that can automatic control the temperature inside tank?
