Batteries

Virtually all power generation systems require some form of energy storage.  For grid-tied systems, the utility accepts surplus power and gives it back when needed.  For systems that need to function without the grid, either all of the time or during an outage, a battery bank is required.  In these systems, the solar array charges the batteries whenever they are producing power and the batteries supply power whenever it is needed.

The most common battery technology used for renewable energy systems is Lead-acid, in which lead plates are submerged in sulfuric acid.  Lead acid batteries (while bulky) are relatively inexpensive and readily available compared to other battery types.

Lithium-ion battery technology encompasses a range of battery chemistries that use various Lithium compounds to store electrical energy.  These batteries are much smaller and lighter than equivalent lead-acid batteries and can be charged and discharged faster and to greater extremes without suffering damage, decreasing the capacity required.  Despite being significantly more expensive than lead-acid batteries, they can be the right choice when transportation costs and/or storage space is at a premium.
