FAQ

Questions  for products

1.Q: How many cycles full charge  and dis-charge about your battery?

A: In 50% discharging deepness, it can be cycled for 1,200 times. In floating charging and dis-charging status, it can be cycled for 5000~6000 times.

2.Q: How to choose the system voltage 12V or 24V for street Light?

A: We can design the System 12v or 24v for solar street Light or 220-380V for normal street light.

3.Q: What's the main difference between mono-cyrstalline and poly-crystalline solar panel?

A: Production process and cost. Poly technology is more mature since it is an earlier technology compared with mono. Poly solar panel is mainly used in solar street light.

4.Q: The controller of your solar street light has time control function?

A: Our solar controller is designed with 4 time-controls function.So you can set up the lighting time in any power requirement and divide it into 4 parts.Example: 12h/night(4h 100%+2h 70%+4h 50%+2h 30%)

5.Q:What information does jiansheng need to offer the best customized solar lamps?

A: (1).Which city will you install the solar street lights in? (2).Road width & road length? (3).What type of road?Highway, National, Suburb or Parking lot? (4).How many hours of lighting per night required? (5).How many continued days lighting without sunshine? (6).If retrofit lighting, what's the existing light type and power? (7).Do you have the site photo? (8).Any other special requirement?

6. Q:What is an LED driver?

A: 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.

7. Q: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.

8. Q: How does the light know when to turn on and turn off?

A:Jian sheng 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. Jiansheng 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 preset 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.

9.Q: What happens if there are cloudy days?

A: 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.

10.Q: What is the typical maintenance schedule for a solar lighting system?

A: 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.

11.Q: Do I have to charge the batteries?

A: Batteries are shipped 85% charged. The batteries will be at 100% charged within 2-3days of proper operation.
