What’s the story?

Solar output depends on available sunlight. Storage can hold energy produced at one time and release it later, including when solar output is lower.

Why does it work this way?

Timing matters because electricity demand does not always match solar production. A battery shifts energy in time, but charging, discharging and storage have limits and losses.

What comes next?

Compare both power and storage duration when reading about a project. A description of a large battery is incomplete without knowing how long it can deliver that power.

Why should you care?

Solar and batteries should be evaluated as complementary equipment, with distinct costs and roles. Storage helps manage supply; it is not an unlimited source of new energy.
