What Details Should Be Paid Attention To When Designing Solar Street Lighting System?

Solar energy is one of the most popular renewable energy. Solar energy resources are inexhaustible. The solar energy irradiated on the earth is 6000 times larger than the energy currently consumed by human beings. Moreover, solar energy is widely distributed on the earth. As long as there is light, solar power generation systems can be used, regardless of geographical, altitude and other factors. Solar energy resources are available everywhere and can be supplied nearby without long-distance transmission, which avoids the loss of electric energy caused by long-distance transmission lines.

Solar street lighting system illuminate the roads by absorbing solar energy and transfer it into electricity. The kind of solar lighting system can bring unending benefits for the citizens and the society. They require nearly no maintenance and no extra electricity bills are generated. If you are eager to invest such outdoor lighting projects, the first thing you need to know is how to configure it.

1. Lighting hours and brightness

First of all, you have to figure out where are the solar street lighting systems are installed. Countryside or cities? The traffic between these two places are totally different. Light hours may be set longer in the cities. Because cities get more traffic. And you need to confirm the lighting efficacy which is measured in lumens per watt. It means how much light is generated compared to energy consumed.  The lumen of the LED chip emits light, its efficiency is high, and the street light will be brighter. Some solar street lighting system manufacturers choose LED chips with lumens in pursuit of profit. LED street lights produced by the latest LED chips will soon be a lower grade.

2. You need motion sensor?

PIR sensor and microwave sensors both belong to motion sensor. Now, many high quality solar street lighting systems use motion sensor to save energy. If someone pass by the light, the light will keep 100% brightness. If people leave, the solar streetlight will drop to 30% brightness. There is no doubt, this way will cost less energy than the auto-time lighting. Solar street lighting systems equipped with microwave sensor would be more expensive. The microwave sensor has longer sensing distance and is more sensitive.

3. Local conditions

The longest continuous rainy days in the area is a very important information. This information determines the battery capacity and the solar panel power required to restore the battery capacity after the continuous rainy days. Another thing to know is the number of sunny days between two consecutive rainy days. It should be noted here that when calculating the relevant parameters, the average sunshine is generally used as the basis for supplementary charging on a sunny day, and the actual radiation amount in a sunny day is greater than the average sunshine. Width of the road is also significant. With the width of the road can we determine the light pole height and the installation distance of the solar street lighting system. Besides, the solar panel of the street light can't be obscured. If there are plants nearby that may be obscure the solar panel, remove them.
