Technological advancements in photovoltaic panels and LED bulbs have made solar lighting more and more popular. The perfect combination of solar photovoltaic and high-efficiency LED brings very good economic benefits upon lighting, also great environment benefits with the clear renewable solar energy. Now there are two generations solar led street lights according to the different structural design: the first generation is separated solar street lights and the second generation is integratedsolar street light.

Battery:

All in two and All in one solar street lamps store power inLithium Iron Phosphate batteries. Lithium Iron Phosphate charges and discharges cycle life is4-5 timesmore than lead acid, also Lithium Iron Phosphate batteries tend to have a longer life span of5-8 timeslonger than Lead Acid batteries.

Lead-acid batteries also don’t work well in higher temperature, life cycle is reduced to almost half for each 10°C increase if the environment temperature exceeds 25°C. But on the other hand, Lithium Iron Phosphate can operate well if the temperature exceeds to 25°C. Also the discharging range of LiFePO4 is-20°C~60°Cand charging rate is0°C~50°C.So, but the main difference on the battery for All in One and All in Two is, thebattery capacity is smallerfor All in One solar street lights as the place for battery is fixed but the battery place of All in two is comparatively big. Also another reason for the for the bigger capacity of battery is due to the larger solar panel mounted on the lighting case to store energy.

In All in two Solar Street lights, the solar panel can beadjusted to the best angle where it is able to absorb maximum sunshine and generate more energy. When the panel doesn’t get enough sunlight, it will work shorter hours at night.

In All in Two split-type solar street lighting systems, the solar panel is not fixed to the lamp so any of the size can be used.Extra-large solar panels can store enough power to last the entire night even during cloudy days or winter seasons.

With the help of advanced BMS, which is integrated on to the Lithium Iron Phosphate batteries, monitoring and controlling battery parameters are made very easy. So, this feature makes it more suitable for the All in One Solar street light solution.

So considering all the facts, both models have various or different attributes and customer usually tend to choose according to their needs. Considering all the demands of customer,EVALandEverSunboth provide better performance as per customer requirement.
