More Batteries vs. More Solar Panels? What''s the Best?

How Batteries Play A Vital Role In The Solar System . Batteries play a crucial role in a solar power system by storing excess energy generated by the solar panels during the day for use during the night or periods of low sunlight. Any excess energy would go to waste without batteries, as they cannot be fed back into the grid.

Why are some batteries not rechargeable?
