1. Different compositions
1. Solar Battery: This is the application of “battery” in solar photovoltaic power generation. Currently, maintenance-free lead-acid batteries are ordinary lead-acid batteries. Batteries and gel batteries are used. There are four types of nickel-cadmium alkaline batteries. The most commonly used solar batteries are mainly maintenance-free lead-acid batteries and gel batteries.
2. Lead-acid battery: The electrode is composed of lead and lead oxide, and the electrolyte is an aqueous solution of sulfuric acid.
2. Different advantages and disadvantages
1. Solar battery: It has the characteristics of “free” maintenance and less pollution to the environment.
2. Lead-acid batteries: The main advantages are stable voltage and low price; disadvantages are low specific energy (i.e.the amount of electricity stored per kilogram of battery), short life and frequent use. daily maintenance. Ordinary old-fashioned batteries generally have a lifespan of about 2 years, and the electrolyte level should be checked regularly and distilled water added.
3. Different applications
1. Solar Battery: Used for reliable solar power systems, especially unattended workstations.
2. Lead Acid Batteries: Used in tractors, tricycles, car starters, etc. Maintenance-free lead-acid batteries have a wider range of applications, including uninterruptible power supplies, electric vehicle power supply, electric bicycles. batteries, etc. Lead-acid batteries are divided into constant current discharge (such as uninterrupted power supply) and instantaneous discharge (such as car starting battery)depending on the needs of the application.
