    Samples are sent by express, usually via customer’s appointed carrier such as FEDEX, UPS, DHL etc.

    Production begins as soon as the customer agrees to our terms, upon sample approval.


     

    Quality Assurance:

    Our process includes many quality procedures, in-line and final production.

    At our workterm, we are committed to quality requirements of the best standard. We do not sacrifice on quality. We make sure quality is adhered to throughout our operation from sampling to final shipment. We take extra efforts in ensuring the suppliers comply with strict quality control. Quality Assurance is an inherent part of our services and we ensure that our customers do not face any problem at any stage


     

    Quality Control and Inspection Procedures:

    We normally follow AQL Level 4.0 inspection method, but on special case we follow any inspection method our customers require. Our quality control and inspection procedure includes the following functions:

    1. Our Quality Assurance department checks all the fabric/Accessories to ensure that quality/color etc conforms to the order / style.

    2. Our Quality Assurance and merchandising team goes to factory location to evaluate pre-production (size set) sample, patterns, etc to approve for trial production.

    3. Quality Assurance team evaluates trial production and then finally approves for bulk production

    4. As bulk production starts, our Quality Assurance team goes for inline inspection. This inline inspection during production is performed on daily basis.

    5. At the middle stage of production if (standard of quality) result is acceptable / good then we go for pre-final inspection. Here we check the case pack, carton quality, shipping mark, assortment, presentation etc.

    6. If the pre-final result is acceptable then we go for final inspection & if it passes, we approve for the final shipment.

    To ensure quality of the highest standard, we inspect at every stage of the production process. The following Quality & Inspection steps are being currently employed in sourcing and manufacturing:

     

    7. Accessories Inspection

    8. Raw Material  Inspection

    9. Measurement Spec checking

    10. Accessories Inspection testing

    11. Accessories Color Matching checking

    FAQ


    • What information does China Sol need to offer you the best customized solar lamps?

      Generally, China Solar Factory needs those questions answered.

      1) The sunshine hours per day or the exact city the street lights will be installed
      2) How many continuous rainy days in the raining season there? (It matters because we have to make sure the light can still work in 3 or 4 raining days with little sunshine)
      3) The brightness of LED lamp(50Watt, for example)
      4) Working time of solar light every day(10 hours, for example)
      5) The height of the poles, or the width of road
      6) It is best to offer the pictures on the locations where the solar lamps going to be installed.

    • What is an LED driver?

      An LED driver is a self-contained power supply that has outputs matched to the electrical characteristics of your LED or array of LEDs. There are currently no industry standards, so understanding the electrical characteristics of your LED or array is critical in selecting or designing a driver circuit. Drivers should be current-regulated (deliver a consistent current over a range of load voltages). Drivers may also offer dimming by means of pulse width modulation (PWM) circuits. Drivers may have more than one channel for separate control of different LEDs or arrays.

    • What is a sun hour?

      A sun hour is a unit of measurement of the intensity of sunlight on the earth at a given time that can be used for generation of solar power, recognizing factors such as climate and weather. A full sun hour is measured as the intensity of sunlight at noon, whereas less than a full sun hour will result during the hours before and after noon.

    • How does the light know when to turn on and turn off?

      China Solar Factory's solar controller uses a photocell and/or timer to control when the light will turn on, when the sun goes down, and to turn off when the sun  comes up.  The photocell detects when the sun comes down and when the sun comes up again. China Solar Factory can make the lamp last anywhere from 8-14 hours, and this varies on the customer's needs.

      The solar controller utilizes an internal timer that is pre-set for a specific number of hours to determine when to switch the light off. If the solar controller is set to leave the light on until dawn, it determines when the sun rise (and when to switch the light off) by means of voltage readings from the solar panel array.

    • What happens if there are cloudy days?

      Electrical energy is stored in the battery each day, and some of that energy is used to operate the light at night. Generally, we design your system so that the battery will operate the light for five nights without charging. This means that, even after a series of cloudy days, there will be plenty energy in the battery to power the light each night. Also, the solar panel will continue to charge the battery (although at a reduced rate) even when it is cloudy.

    • What is the typical maintenance schedule for a solar lighting system?

      There is no regular maintenance required for a solar lighting system. However, it is helpful to keep the solar panels clean, especially in a dusty climate.

    • Do I have to charge the batteries?

      Batteries are shipped 85% charged. The batteries will be at 100% charged within two weeks of proper operation.
