Different Types of Solar Light For Sale
Solar Street Light
These bulk solar light china are mainly developed to illuminate large areas with the highest intensity of light, such as Street Lighting, Roadway Lighting, Pathway Lighting, Ramp Lighting, Sidewalk Lighting.

Solar Garden Light
Coupled with unique optical designed, these China solar lights with high luminous efficiency can be irradiated to a wider area. They provide a perfect way to emphasize the beautiful landscaping in your garden.

Solar street lights use solar energy as the energy source. Capable of realizing conversion from photovoltaic to electricity through solar panels, the solar powered lights produced by Anern use their batteries to store electricity during the daytime, and power the light through the controller at night to achieve the required functional lighting. As a mature solar light supplier and solar light manufacturer, Anern is a comprehensive enterprise with 12 years of experience in R&D, production, and sales of China solar lights. Anern owns dozens of product-related patents, and our different types of solar lights are sold to more than 100 countries around the world, participating in the completion of thousands of government solar lighting projects.

How Do Solar Lights Work
Solar lighting uses solar panels to absorb solar radiation during the daytime and converts it to electrical energy. It is stored in the battery bank through a charge and discharge controller. At night, when the daylight gradually decreases to about 10lux and the solar panel open circuit voltage is about 4.5V, the controller shall detect this voltage value and then direct the battery to discharge and power the led bulb light source to realize functional lighting.

Solar Light Components
Batteries
There are two main types of batteries for solar-powered lights, lead-acid batteries, and lithium batteries.
The advantages of lead-acid batteries are that they have been used in solar lighting for the longest time, and are more stable and cost-effective. The disadvantage is that the lead-acid battery is large in size and can generate serious environmental pollution during production, and its price fluctuation is big due to the effect of the lead cost.
The advantage of lithium batteries is that under the same capacity, their volume and weight are smaller than lead-acid batteries, the energy density is bigger, and its use is more flexible. The disadvantage is that its price is higher compared with a lead-acid battery. However, with the technical development and increasing high acceptance in the market, the lithium battery cost has gradually decreased and becomes the main battery type used in solar lighting.

Solar panel
Solar PV modules, also called solar panels, are the core part of the solar photovoltaic power generation system and the most valuable part of the solar energy system. Its function is to convert the sunshine radiation to electric energy and send to batteries for storage. It can also energize the loads directly.
Controller
The controller mainly plays the role of charge/discharge control and management in the solar lighting system. During the daytime, the solar panel generates electricity and charge to the battery through the controller. At night, the battery of the solar lights is discharged through the controller to supply power to the light source for lighting. When the rainy days are too long, if the battery voltage drops below the controller preset battery lack-of-power voltage, the controller shall cut off the battery power supply. In addition, the controller has an intelligent power mode which can adjust the light source brightness based on battery surplus capacity for energy-saving purposes and can extend lighting time to the maximum in continuous rainy/cloudy conditions.

LED Light Source
LED is the newest generation of light sources. Currently, different types of led lights are widely applied in both outdoor lightings such as street lights, floodlights, garden lights, and also indoor lighting such as bulbs, tubes, ceiling lights, etc.

Solar Lights Replacement
Anern solar-powered light has engineering quality. We promise that the raw materials we used do not contain any defective or second-hand product.
When solar-powered lights failure occurs, please check the following places:
Please check whether the solar panel wire is connected to the lamp cap wire and tighten it.
When connected to the solar panel line, the battery indicator (red light) of the controller will always be on, if not on, the battery may be out of power. Place the lamp cap and the solar panel in the sun at the same time and then observe the state of the controller indicator, to see whether the red light is always on and the blue light flashes slowly; If the indicator lights are not on, please consult the engineer of Anern for further guidance.
Regularly check the remote. Press the remote control to see is there any flashing at the controller. If there appears no flashing, adjust the remote distance and then

FAQs of Anern Solar Lights
Q： How bright are solar lights？
A：First of all, the lighting range of the solar-powered street lights is not fixed and will be affected by the height of the solar street lamp, the power of the lamp head, and other factors. Generally speaking, the illumination range of a 6 meter China solar light is about 20 square meters. The installation distance between two solar-powered lights is best controlled in about ten meters so that the installation of solar street lamps is the best.

Q： How long do outdoor solar lights last？
A：Generally, the batteries of the bulk solar lights will work for about 3-4 years and the solar lights themselves can last for about 10 years or more.

Q：How do i make my solar lights brighter？
A：To make the solar lights shine brighter, you need to make sure the solar panel is adjusted to the right angle so as to receive the solar power as much as possible. Moreover, it is also very important to clean the solar panel on the regular basis.

Q：Should solar lights be left out in the winter？
A：As a professional solar light supplier, Anern produces high-quality solar lights, such as our commercial solar flood lights, that can be left out even in cold weather. Feel free to ask us for more info.

Q：Should you turn solar lights off at night？
A：By turning off the solar lights, you can give the battery a chance of getting a full charge over several days of sunlight. It is up to you to decide whether you would love to turn the solar lights off or not.

Q：Can you charge solar lights without the sun?
A：Solar-powered lights can also be charged when there is no sun, but the amount of charging will vary according to the degree of overcast and rainy days. The bulk solar lights at Anern are all equipped with battery charging and discharging devices, usually, when the sun is full, they will charge themselves. And these solar lights will rely on battery power to maintain the power supply of street lamps on rainy days. On cloudy days when the sun's light is weak, the charging capacity of solar light is relatively weak.

Q：Do outdoor solar lights need rechargeable batteries？
A：Outdoor solar lamps normally require rechargeable batteries because the solar panels of this type of solar light will convert sunlight into electricity, so as to further charge the batteries which will then power the lamps.

Q：What to do when solar lights stop working ?
A：First check whether the controller of the solar-powered lights is broken. If the controller is broken, then you should conduct a timely repair towards the light controller. Then you should observe the recent weather conditions. The normal charging of a solar-powered light should last for about 5-7 hours per day, so if the charging is only up to 2-3 hours such a situation is normal. Finally, you can check whether the battery inside the solar light is broken.
