  • What are Solar Lights?

    If Scientifically define, Solar lights are portable light fixtures composed of LED lamps, photovoltaic solar panels, and rechargeable batteries.

    If you need more information please, don't hesitate to contact us. Our staff will be glad to help you in any your requirements.

  • Do I have to charge the batteries?

    Batteries are shipped 60% -70% charged. The batteries will be at 100% charged within two weeks of proper operation.

  • What do we need to know to customize your solar light project?

    In order to customize your solar light project the first thing we need to focus on is the location for installing the solar power lighting system and the perfect location where you want to install your solar light project, because different locations and surface have different levels of sunlight which can have an impact on the outcome of the solar light project.If you tell us the location where you want to install the solar LED systems, we can estimate the irradiation to calculate the solar panel size.

  • 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.

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

    Shangqi’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. Shangqi 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.

  • Which types of warranties you will have?

    1. Solar Panel: mininum 25 years of power generation capacity, with 10-years warranty
    2. LED Light: Mininum 50.000 hours life span, with 2-year all inclusive warranty - covers everything on the LED street lights, including lamp holder parts, power supply, radiatior, scaling gasket, LED modules & lens
    3. Battery: 5 to 7 years life span, with a 2-year warranty 
    4. Controller inverter and all the electronic parts: Minimum 8 years by ordinary usage, with a 2- year warranty
    5. Pole solar panel bracket and all the metal parts: up to 10 years life span
  • 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.

  • Which are the information you should give us to best customize our solar lights?

    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 5 raining days with little sunshine)
    3.The brightness of LED lamp(50Watt, for example)
    4.Working time of solar light every day(12 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
