Best 12W Solar Street Lights

Application scene: Secure a 3-5 meter pole height to the outdoor public lighting places. Some of these public places include parks, community corridors, community public spaces, bicycle parking lots next to public buildings, etc. Technical suggestion: Set the LED power between 10W and 20W according to the height of the street light pole, the customer’s requirements, and the budget for brightness. You should adjust the solar panel power and battery capacity according to the LED power. ADN highly recommends using a 3V low voltage battery system for this wattage outdoor solar light. Nothing else, a 3V low voltage battery system can low down the cost a lot.

The usual wattage of these solar lights is between 30W and 60W. Higher wattage can be made, but the solar panel and battery size will become quite large. Therefore,  using them to make low-wattage solar lights, the cost will become relatively high. However, in some projects, a street lamp is selected because of its unique design. After all, a good product is what customers will spend money on. This is why ADN keeps developing new solar lamps every year.

Best 30W 60W Solar Street Light

Application scenario: The outdoor public lighting from 6 meters to 8 meters must be considered. For example, parks (6 meters), community roads (6 meters), country roads (6 meters to 8 meters), public lighting sites in remote areas (6 meters to 8 meters), commercial streets (6 meters to 8 meters), industrial areas Roads and parking lots (6m to 8m), main road (8m). 

Technical suggestion: The average lighting brightness basically needs to reach 15 lux – 20lux. The dimming method is set to induction dimming, time-controlled dimming, and mixed dimming of the above two dimming methods according to the traffic flow and the flow of people. The appearance of the lamps can be selected according to the installation site conditions and customer preferences.

Because the application scenarios of this part are the most critical in solar street light applications. ADN then decided to make more detailed solar street light solutions for the following scenarios: the 6-meter-high solar street light scheme in low-latitude areas, the 6-meter-high solar street light scheme in mid-dimensional areas, the 8-meter-high solar street light scheme in low-latitude areas, and the 8-meter-high solar street light scheme in mid-dimensional areas.

The 6-meter-high Solar Street Light Scheme in Low Latitude Areas

Countries like the Philippines, Malaysia, Saudi Arabia, South Africa, Thailand, Nigeria, Southern United States, and so on belong to low latitude areas. These places have long hours of sunshine, and the temperature stabilizes between 10°C and 40°C throughout the year. There are also some projects with low budgets that prefer to use the above solar street lights. The actual power is about 10 watts to 15 watts, and the false label is 100 watts to 300 watts.

If the project requires high-quality 30W full-power solar lights, the usual configuration is as follows:

  • Led Power:30W 
  • Lumens:4000lm – 5500lm
  • Battery:12.8V 21AH – 24AH
  • 30% Pir motion dim
  • Solar panel: 50W-60W
  • 2-3 cloudy days whole night lighting
  • 3-5 years warranty
  • EXW Price: 

The 6-Meter-High Solar Street Light Scheme in Mid-Latitude Areas

Countries such as Spain, Germany, the United Kingdom, France, Australia, parts of the United States, etc. belong to Mid-Latitude Areas. The temperature in these places will hover at the freezing point for 1 to 2 months in winter, and there are relatively high requirements for the stability of lighting time. ADN suggests increasing the solar panel power to make it more effective than increasing the battery capacity. Choose low-temperature resistant batteries, such as gel batteries (large volume, heavy weight, and cheaper). You may also opt for ultra-low-temperature lithium batteries (which can reduce the operating temperature to about minus 40 degrees Celsius, but the price is 3 to 4 times higher than ordinary lithium batteries), or LiMn2o4 Lithium Battery. 

See our solar lighting solution below.

  • Led Power:30W 
  • Lumens:4000lm – 5500lm
  • Battery:12.8V 24AH – 30AH
  • 30% Pir motion dim / 4 hours 100% brightness, 30% brightness in left hours
  • Solar panel: 60W-80W
  • 2-3 cloudy days whole night lighting
  • 3-5 years warranty
  • EXW Price: 

The 8-Meter-High Solar Street Light Scheme in Low Latitude Areas

Generally, the 8-meter height pole is basically installed on the main road. Since Party A of the main road lighting project is for a government agency it should follow strict requirements. Specifically, these projects have strict requirements on brightness, lighting time, lighting time in rainy weather, and life expectancy. Thus, designs may vary slightly depending on budget. 

Below is our solar lighting solution:

  • Led Power:40W – 60W
  • Lumens:6000lm – 11000lm
  • Battery:12.8V 30AH – 54AH
  • 4 hours 100% brightness, 30% motion dim in left hours
  • Solar panel: 70W-110W
  • 2-3 cloudy days whole night lighting
  • 3-5 years warranty
  • EXW Price: 

The 8-Meter-High Solar Street Light Scheme in Mid-Latitude Area

The same as the above scene, Party A of the 8-meter height street light pole project is generally a government agency. Most likely, customers from European and American countries have stricter requirements (on brightness and lighting time) during the rainy season. 

See the solar lighting option we provide below:

  • Led Power:60W – 80W
  • Lumen:10000lm – 15000lm
  • Battery:12.8V 54AH – 72AH
  • 4 hours 100% brightness, 30% motion dim in left hours
  • Solar panel: 110W-150W
  • 2-3 cloudy days whole night lighting
  • 3-5 years warranty
  • EXW Price: 

Best 100W Solar Street Lights

Application scenarios: Main road lighting and highway lighting from 8 meters to 12 meters, basketball courts, grab courts, golf courses, etc.

Technical advice: These places have the highest requirements for lighting brightness and lighting time. The lighting brightness needs to reach 20 lux to 30 lux. So, the 100W mentioned in the title is not the highest wattage of solar street lights. Making solar street lights with higher wattages is not difficult. The challenge lies in installing oversized solar panels and batteries and ensuring they can withstand storms for many years.

As for the dimming mode, some customers want to keep the LED lights working at full power all night. We still recommend that customers at least apply time-controlled dimming. After all, making sure the LEDs work at full power all night requires a considerable increase in the cost of adding solar panel power and battery capacity. Consider our solar lighting solution below.

Split Solar-Powered-Street-Lighting
  • Led Power:80W – 150W
  • Lumens:15000lm – 27000lm
  • Battery:25.6V 80AH – 120AH
  • 6 hours 100% brightness, 50% in the left hours
  • Solar panel: 250W- 500W
  • 2-3 cloudy days whole night lighting
  • 3-5 years warranty
  • Customized design of the installed bracket for battery and solar panel

Recommendations for Solar Street Lights in Cold Regions at High Latitudes

The application of solar street lights is limited in high-latitude and cold regions for two main reasons: too low a temperature impacts battery charging and discharge, and the lighting time is short. The following is a summary of ADN’s experience.

With Cold-Resistant Batteries and Buried Batteries

Compared with lithium batteries, the minimum operating temperature of colloidal lead-acid batteries can reach minus 20 degrees Celsius. And the cost of lead-acid batteries is much lower than that of lithium batteries. Instead, use a low-temperature lithium battery that can work at temperatures around minus 40 degrees Celsius. Although, the cost of low-temperature lithium batteries is 3 to 4 times higher than that of ordinary lithium batteries.

Another way to keep batteries warm is to bury them in the soil. You can also wrap thermal insulation in the battery case. We do not recommend heating the battery pack to keep the battery warm. This method cannot ensure that all battery cells are heated uniformly. This will affect the cycle life of the battery pack.

Hybrid Wind Power 

Wind and solar energy can be added to power the solar lights. With the absence of solar energy due to the rainy season, wind power can become more prominent. However, because the demand for wind and solar street lights is not very high, the quality of the related controllers is not also stable. So be sure to choose the controller supplier carefully.
