Specifications

1,Germany improted blue titanium absorbers
2, Laser welding for copper and absorber
3, 25 years lifetimes,SRCC Solar Keymark

 

 

The following is our solar collectors’ advantages:

 

1)S-type tube flat plate solar collector,have gotten the line patent in China.no any

 

welding on the tube,no any leakage.

 

2) Laser welding between whole absorber panel and copper tube, high strength

 

thicken heavy duty aluminium frame.

 

3) The instant heat efficiency of the collector can up to 81.1%,much higher than the

 

72% standard,very rare in China.

 

4)Germany imported high efficient selective blue titanium coating.use best copper

 

tubes in domestic.

 

5)Special low-iron tempered glass with transmittance more than 92%.

 

6) Mechanical load, freeze resistance, rain penetration, exposure, hail impact,

 

external andinternalshock tested etc.

 

7) Long lifetime, large absorber area,good warm keeping , European,North America

 

specialdesigned.

 

Manufacturing technique difference

 

 

 

 

 

 

 

 

 

 

1)Laser welding strengh tensile test

 

Quality requirements: 1, the strength tensile of welding >=10 Kgf.

 

2)Resistance to high temperature aging tes

 

Quality requirements:

 

a, after test, appearance have no

 

deformation, discoloration, stratification of volatile fade, crack and breakage.

 

b, after test, under the performance of the prescribed temperature,

 

all the performance parameters of carbide change should comply with the

 

relevant standards

 

3)Impact resistance test

 

Quality standard requirements:

 

The test result judgment criteria: 1.0 m, no broken, no crack of qualified

 

4)Rainfull test

 

Quality standard:

 

four hours in the rain,water into collector: <5 g/m2 or less.

 

Flat plate collector shall not be damaged and produce a large number of water vapor and water droplets

 

5)Visible light through/ reflectivity test

 

Quality standard:

 

a,no dark marks in the test products smooth surface which should be clean, no

 

variegation, bubble, crack,qualitative, defects such as gas line.

 

b,Light transmittance >= 91% or higher

 

6) Hardness test

 

Quality standard requirements:

 

a,the material is black, the hardness is type A 70 degree +/- 3

 

b,material surface is smooth and soft elastic.

 

The more test items and each test process ,we will show you in our testing room

 

when you come to visit our company if possible.
