7 KEY POINT FOR SOLAR LIGHTING PROJECT
You do not always need to pay attention on questions of how much brightness and how long it can last when you are doing a traditional LED lighting, because you knew what power it requires, what brightness it demands before you decide to start lighting project. then dig ditch, lay cable and connect to grid, you will get them done after turn on switch.
The appropriate solar street light will be good option if you do not want spend money and time digging ditches and lay cables. At moment, solar street light can reach similar lighting performance to traditional LED lighting, the precondition is we need to confirm each parameters with solar street light supplier and make sure lighting performance reach demand.
In this article, I will help you give suggestion on how to assess a lighting project is available solar lights or not, and how choose a suitable solar lighting solution. First of all, I will introduce some information before project started, which is better for comparing a different solar lights models.
Contractors need to make 7 questions clearly when collecting manufacturer or product information.
Propose 7 questions assist contractors get an appropriate solution based on overall demand, budget, why we need to realize the 7 key points.
Avoid budget beyond: Make sure lighting system at a good condition between cost and lighting performance, we do not only get a lighting performance solution, but also have a cost competitive solution, avoid solutions with high cost while its technology has large shortage.
Avoid replacing battery frequently or system defects: Installing an advance lighting system instead of battery or controller at bad condition.
1. Get to know project location?
We need to know specific location, because supplier can consider relevant factors in the lighting system.
Different areas receive different sunshine strength, for example, in western and eastern, their solar radiation is different and in different seasons, which is also different, we can check specific solar energy radiation rate and make decision.
Besides, we need to consider shade factors, like tree, building and other subject may cover sunshine for solar panel.
2. Get to know application field
What kind of district you would light? Different area road has different lighting requirements.
Why? Different application areas has different effects for pole height, distance between poles and lighting level demand, for example, solar lights at pathway has higher brightness demand than garden or alley, some applications may below:
pedestrian street, neighborhood, garden, parking lot, main road, building entry and etc.
3. Get to know project lighting area dimensions
Distance of road/street and area of parking lot?
Why, lighting area and street distance affects required solar lights numbers and lighting uniformity, all of these factors can affect project cost, for example, some projects like below:
20000 Square meter playground, 1000 meter road, 150m x 300m parking lot.
4. Get to know what kind of lighting pole
Do customer has specific demand for poles? Like pole height, color and pattern.
Why, because pole height can affect light numbers, which is related to cost. For example, ordinary road need 6-7m pole, public passage is 8-10m pole.
5. Get to know required light level
Each country government has their own lighting level demand, they are mainly for light intensity, lighting uniformity and etc.
Why, different application has different light levels, which is very important for the project, we can do it according to Road Lighting Design Standard.
6. Get to know Operating Profile
How long lighting in night? When light on, what specific time frame must meet lighting requirement? You must need an experienced supplier to get solution if you are not sure about this.
Why, in specific operating aspect, factory will adjust battery controlling system according to customer’s different demands.
Below is common solution,
Light all night: solar light will be on through all night.
Turn lower brightness in off peak time: for example, light is on at 100% brightness at 5hours and turn to lower brightness to 30% in other 5 hours and turn to 100% brightness in last 2 hours.
Light on in specific time frame: for example, light on to 11P.M and turn off.
7. Get to know required color temperature
Need to what temperature required, 3000K or 6000K?
Why, different citizen prefer different color temperature, while most people like high temperature.
Above all, we indeed to realize relevant design and requirements, the lighting projects has large budget invest, we need to make sure every aspects compatible to technical standard and get best solution.
