Which energy storage technology is most commonly paired with solar power systems for residential use?

  1. Lead-acid battery
  2. Lithium-ion battery
  3. Flow battery
  4. Compressed air

Answer: Lithium-ion battery

Lithium-ion batteries offer high energy density, long cycle life, and declining costs, making them ideal for residential solar storage. Lead-acid is cheaper but heavier with shorter lifespan. Flow batteries suit grid-scale storage. India's PLI scheme promotes domestic Li-ion cell manufacturing for energy transition.
