Perhaps the most important nexus between solar power and evs is energy storage he said in particular referring to ev batteries being reused to store solar power.
Car batteries for solar power storage.
This is very similar to an energy storage system where you may be generating power from solar wind water or magnetic power even as you are using electric devices that feed from the batteries.
Capacity is the total amount of electricity that a solar battery can store measured in kilowatt hours kwh.
As long as you keep the drain low you can indeed use a shallow cycle battery for storing power and a steady discharge.
With unreliable solar battery storage you will only be able to enjoy solar power when the solar panels are producing it.
Although a car or truck battery may be used for a small solar power system it may only have a life of 2 to 3 years if used continously compared to 10 to 15 years for a deep cycle battery.
The car or truck battery is therefor designed to be used virtually fully charged all of the time.
Moreover since the panels produce energy during the day and you may not use all the energy at the time a stable power bank is essential to store this energy.
