Q:How many cycles full charge & discharge about your battery?
A: In 100% discharging deepness, it can be cycled for 2000~3000 times.
Q:How to Choose the System Voltage 12V or 24V or for normal solar street Light ?
A: We can design the System for 12v or 24v for solar street Light or 220-380V for normal street light .
Q:What's the main difference between mono and polycrystalline solar panel?
A: production process and cost. Polysilicon technology is more mature since it is an early technology compared with Monosilicon.
Q:The controller of your solar street light has dual time control function?
A: our solar charge controller is designed with dual time control function, you can set up the lighting time and divide it into two parts, like 12 hours (6 hours full power lighting + 6 hours half power lighting)
Q:What information does Borui need to offer you the best customized solar lamps?
A: I·· Which City will you install the solar street lights?
I··Road width & road length?
I··What type of road? Highway, National, Suburb or Parking lot?.
l ··How many hours of light per day required?
l ··How many continued days lighting without sunshine?
l ··If retrofit lighting ,what's the existing light type and power?
l·· Any other special requirement?
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.
Q: How does the light know when to turn on and turn off?
A: BoRui'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. Sun master 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.
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 two-three 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.
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.
Q: Do I have to charge the batteries?
A: Using the rated voltage of 4.2 V constant current constant voltage charger can make the lithium ion battery in one or two hours to get filled
