          Material Equipment

          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;
