 Batteries store electricity for night time in off grid solar systems. An off grid home will have 4 to 6 days of storage in the batteries, while grid tie systems may have no batteries at all. Batteries also help loads to run at a constant voltage, while allowing the solar modules (or other power sources) to still charge as much as it can. In On Grid homes, batteries are only used to power loads if there is a blackout.
Batteries are the "weakest link" in a modern solar system. They're heavy, full of lead and sulfuric acid, require regular maintenance, and will wear out sooner than any other component. |
