When it comes to the install solar street light project, a lot of people would ask what is solar street light is and how do I find a trustable solar street light manufacturer. Usually solar street light is a huge project, it needs to be customized based on the climate conditions of the users. The top solar street light manufacturers will configure cost-effective light solutions to provide efficient lighting. This article is a guide on how to choose a good solar street light manufacturer.
1. Which type of solar street light that the manufacturer provide?
Solar street lights are composed of split solar street lights and all in one integrated solar street light. What’s the difference between these two types of solar street lights?
Split type solar street light: the solar panel is separated from the light source and the battery.
All in one led solar street light: It is to integrate all the components and connect them together. It integrates the solar panel, rechargeable battery, LED light source, controller, mounting bracket, etc. into one street lamp.
The integrated light advantage is easy to install but the disadvantage is the angle of the solar panel can’t be adjusted. The split type can adjust the angle of the solar panel. You need to know the lights that the manufacturer provided. Some small manufacturers only provide one of them. You can provide your requirements for the solar street light so that the manufacturer can configure the light that suits you.
2. Warranty period and maintenance provided by the manufacturer
The lifespan of solar street lights is affected by many factors, such as the lifespan of batteries, solar panels, etc. A high-performance solar street light system can be used for at least 5 years if properly maintained. most solar street light manufacturers in China provided 2-3 years warranty, some quality solar street light suppliers provided 5 years warranty. However, solar street lamp maintenance matters a lot. Top solar street lamp manufacturer has a perfect after-sales team.
3. Solar street light battery used
The battery is a key factor that affects the lifespan of solar street lights. Lead-acid battery, ternary lithium battery, lithium iron phosphate battery can all be used. Among these batteries, the lithium iron phosphate battery has the best performance, although the price is a little higher. To find a reliable manufacturer, you should know the components that they used in the street lights are good or not. Solar street light is consist of solar panels, batteries, controllers, light sources, etc. The quality of each component is significant. Some manufacturers will use low-quality materials to replace the good ones.
Don’t just look at the parameters only
When we buy quality solar street lights, we must not just look at the specifications advertised by the suppliers, because the battery that the supplier may advertise is 100Ah, but the actual product purchased is only 10Ah. Even with the same capacity, the available capacity of batteries of different grades is different. For the same solar street light, some suppliers label 60W, and some may label 300W.
The actual capacity of the battery
Some parameter table Ah looks very big, but in fact, we bought Wh instead of Ah. Wh=Ah*V, we can’t just look at the capacity of Ah, but also the voltage. E.g:
90Ah, 3.2V actual battery capacity is 90Ah*3.2V=288Wh.
30Ah, 12.8V actual battery capacity is 30Ah*12.8V=384Wh
4. Pay attention to the number of continuous rainy days
One of the important indicators of solar-powered led street lights is the number of continuous rainy days. At present, most solar street lights on the market still can only provide lighting for three to five consecutive rainy days. The battery capacity of this kind of solar street lamp is also often depleted, resulting in a decline in battery life. Therefore, it is recommended not to buy solar street lights with few continuous rainy days. When buying the solar street light, provide the longest number of rainy days in the local area so that the solar street light manufacturer can configure a suitable battery according to the customer’s local climate.
5. Cheap price ≠ Cost-effective performance
Solar-powered led street lights with false standard parameters cannot be purchased. There are many solar street lights with false standard parameters on the market. These products use false standard parameters such as light sources, solar panels, batteries, and electrode materials to reduce costs and achieve the purpose of attracting customers.
Let users spend the same money but buy substandard products. These products are shoddy and contain a variety of safety hazards. Even if the price of this solar street light is very low, it cannot be purchased
People want to buy the cheapest solar street light, but the cheap ones do not mean the most cost-effective. It also depends on the effect and longevity. For example:
With the 10 years lifespan of a $300 high-quality solar light, the average annual cost is $30.
With the 1-year lifespan of a $100 poor-quality solar light, the average annual cost is $100. If it is broken, there is a waste of time and energy cost, which is actually not worth it.
We hope you will know how to choose the right solar street light manufacturer after reading this article.
