All in one solar street light refers to the new generation solar led street light that integrated solar panels, batteries, controllers, LED lights into one lamp body. Compared with the first generation of split type solar street lights, the biggest difference in the new generation of solar street lamps is their structural integration. In practical application, each generation of solar street light has its advantages and disadvantages. Below we will specifically talk about the guide to choose all-in-one solar street light.
Solar panel is one of the components of the lamp body. Its quality is related to the lifespan of all-in-one solar led street lights. so it is one of the factors we must consider when choosing lamps. Generally speaking, monocrystalline silicon has better performance than polycrystalline silicon, especially in cold weather. monocrystalline silicon has higher energy conversion rate than polycrystalline silicon.
The solar panel size of all in one solar street light is smaller than that of split type solar street light . because the solar panel of split type solar street light is separated from the lamp body. The size can be customized as needed. However, this is not the case with all-in-one solar street light. the size of solar panel not only is constrained by the size of street lamps but also need to consider the convertible amount of solar energy within fixed time .
In earlier design , in order to give consideration to both of factors,all in one solar street light enlarge its top panel size , which make it larger than that of general national grid powered led street light at the same power.This is contrary to people's pursuit of compact and simple concept, but also does not conform to people's aesthetics of modern fashion style. on the premise of not expending the solar panel. adopting mono-crystalline silicon material as solar panels is undoubtedly an ideal solution.
It is understood that lead-acid battery, lithium battery, liFePO4 battery are three types of battery that all-in-one solar street light may use. among them, Lead-acid batteries can be used for 300-500 times and their service life is about two years. Lithium batteries can be used for more than 1200 times with a service life of 5-8 years, and LiFePO4 batteries can be used for more than 2000 times with a service life of more than 8 years. Therefore, the type of battery used by all-in-one solar street lights is also one of the information to be understood when choosing lamps.You can't just focus on price when choosing all-in-one solar street light. LiFePO4 battery is featured with small size , long service life, and high environmental value. it has been the industry's first choice for integrated solar street lamp batteries though the cost may be higher. The least recommended is lead-acid battery, which are very harmful to environmental pollution.
Since the solar panels of all-in-one solar street lights are integrated into the lamp body, the installation angle of the lamp body not only need to consider the problem of maximizing the amount of solar radiation received, but also need to consider the light distribution of the solar street light. And we all know that the optimum tilt angle of a solar panel is likely to vary from latitude to longitude. The orientation of the solar panels of all-in-one solar street lights cannot be adjusted as optionally as that of split type solar street lamps.
Street lights are installed at different latitude and longitude with different surrounding environment , where the demand of light distribution may be also different. The adjustable installation angle of lamp body can better deal with the diversity and complexity of the location of solar street lights and take into account the continuity, uniformity, maximization of solar radiation as well as the light distribution.
The all-in-one solar street light is a complete closed operation environment that operates independently from the national grid. Sunlight shines on solar panels, which absorb sunlight and convert it into electricity. During the day, the solar panels charge to the battery. at night, the battery supplies power to the LED street lamp to complete the lighting function. But precisely because of the independent operation characteristics of the whole all-in-one solar street light, continuous rainy weather, an unstable factor, has to be paid attention to when choosing integrated solar street lamps. The longer the lighting time for days of continuous overcast whether,the better the performance of all-in-one solar street lamps
Though solar energy is a free energy source , the electricity converted by solar energy is very precious. The capacity of the battery is limited, so is the duration of the power supply. Expanding the battery capacity infinitely is an unrealistic idea. extending the lighting time as long as possible with limited storage capacity of the battery is a more feasible way. Therefore, the combined use of all-in-one solar street light and intelligent control is very important.Through intelligent control, lighting on demand can be set, and the stored electric energy can be fully applied where necessary without too much waste.
Of course, as a kind of outdoor lighting, when buying all-in-one solar street lamps , it is also required to carefully understand its power ,IP rating, installation methods and other characteristics as you do usually. hope this guide help you well.
