Quality Control from the source- Copper Tubes
*Copper tube adopts TP2 copper oxidation resistance, corrosion resistance is strong.
TP2 copper excellent welding performance, welding node good ductility;
*Copper adopt domestic brand copper suppliers, to ensure the quality of copper;
*Copper wall thickness are above 0.6 mm to ensure the sealing of copper pipe flow;
Solar Industry Disclose
1, In order to reduce costs, some manufacturers use inferior copper pipe instead of high quality copper pipe;
2, In order to reduce costs, some factory products are inconsistent with the contract requirements, when mass production, some factories changecollectors inside diameter and wall thickness of the copper pipe;
Solution: sample testing ( random testingq when massProduction )
Quality Control from the source - Aluminum Alloy Frame
* 6063 - T5 aluminum hou resistance is strong, high mechanical strength, is the guarantee of flat collector sturdy and durable ;
* Aluminum surface oxidation treatment,surface generates a layer of protective film layer, to ensure that the plate collector to adapt to the harsh outdoor environment;
* Our aluminum alloy frame from domestic brand aluminum suppliers.
Quality Control from the source - Absorber Material
Absorber is used with imported Germany high efficiency bul titanium, it is of high absorbility, low emissvity, α≥95%, ε≤5%, stable performance.
Quality Control from the source - Absorber Material
The material is EPDM with the good & reliable famous brand supplier,it is of Anti High temperature, weather resistance, uvioresistant,can be more than 20 years working life.
Quality Control from the source -Glass cover
It is used 3.2mm low iron braided tempered glass, the light transmittance can upto 91.2%, also the matted finish on the glass can prevent the second reflex, more important, the hardness of the tempered glass is 5 times harder than normal glass.
Quality control from the source - thermal insulation material
*Insulating materials use glass fiber cotton and stearic foam polyurethane
*Glass fiber cotton high temperature resistance, ageing resistance, coefficient of thermal conductivity is 0.042 W/M * h * ℃, insulation Can good, high hydrophobic, cost-effective;
*Hard foam polyurethane, coefficient of thermal conductivity is 0.027 W/M * h * ℃;
*Our insulation materials are from domestic brand suppliers;
