There are two main types of solar batteries: lead-acid batteries and lithium-ion batteries.

  • Lead-acid batteries: Lead-acid batteries are the most common type of solar battery. Lead-acid batteries are relatively inexpensive, but they have a shorter lifespan than lithium-ion batteries.
  • Lithium-ion batteries: Lithium-ion batteries are more expensive than lead-acid batteries, but they have a longer lifespan and a higher energy density.
