Solar street lamps of 10 meters high

Now many rural areas are already installed solar street lamp, solar street light battery lithium battery and lead acid battery, it can be stumped a lot of buyers, many buyers buy solar street light often entangled with this problem. Now solar

today, solar street lights have been installed in many rural areas, but the battery solar street lamps divided into lithium battery and lead acid batteries, this makes many buyers are confused, they often encounter the problem when buying solar street light. At present, solar power lithium battery technology is very mature. No matter how much the price of solar street lights and use effect, solar street lamp manufacturers think use lithium batteries have more advantages. Why do you say that? We know that the battery is installed on the external and buried in the ground. If the external, it is better to install on the height of 6 meters of solar street light, solar street lamp beside should not have to climb, pay attention to guard against theft; If the embedded type, it is better to pay attention to waterproof, the ground should be compacted concrete, effect is better. Lead acid battery and lithium battery has different features, we can from these four aspects carries on the analysis and comparison: 1. Power supply mode: lithium-ion batteries in 24 v 120 ah's storage capacity is higher than lead-acid batteries 12 v storage capacity of 200 ah. Lithium battery can be recharged, service life is 3 ~ 5 times of lead-acid gel battery. 2. Annual maintenance cost: the life of the lead-acid battery for 2 ~ 3 years, the total life of lithium-ion batteries for 8 ~ 10 years, the service life of the lithium battery for 10 years, almost no maintenance cost. 3. Environmental protection: lead-acid battery production pollution is serious, lead-acid battery can not recycling, heavy metal pollution is serious, is not a green battery; Lithium battery is a kind of environmental protection batteries. Lithium is a kind of light elements, harmless to the human body. The iron in the soil are everywhere. 4. Costs and expenses: the lithium battery is a new kind of environmental protection battery, the price is slightly higher than that of lead-acid batteries. Therefore, manufacturers think solar street lamps, solar street lamps use lithium iron phosphate batteries, has more than 2000 times charging and discharging cycle, long service life, high safety, high temperature resistant performance is good. These are lead-acid batteries.
