There are three major types of solar cells in solar street lamps, namely lithium batteries, lead-acid batteries and colloidal batteries. Among them, lithium batteries are increasingly favored by the solar industry because of their higher service life. So, what are the advantages of using lithium batteries for solar street lamps?
1. The charging and discharging system adopts the integrated structure of lithium battery and controller, and is a storage battery system with controllability and pollution-free. Lithium batteries generally last up to 10 years and are perfectly matched to LED streetlight systems in practical applications.
Second, lithium battery solar street light can also be based on user demand, intelligent optimization calculation of lithium battery residual capacity, day and night time, weather conditions and other factors, and reasonable distribution of power levels, and achieve light control, time control and storage memory and other functions, Make sure that 365 days are lit every day.
Third, lithium batteries are dry battery properties, more secure, more stable and safer than lead-acid batteries.
4. Lithium batteries can only be used in areas below minus 20 degrees due to the influence of temperature. They can not be used in colder north and northeast areas.
