Solar batteries
 
Batteries are sources of energy (discharging) via period when solar modules, wind or hydro agregate do not produce, respectively excess store of produced energy (charging). Ratio between obtained energy during discharge and energy which is required for battery charge is called efficiency. Mode method in which battery is usually discharged and charged is called cyclic and is extremely demanding for battery.   durability in cyclic operation
high efficieny ( > 85% )
small self-discharge ( < 3% monthly )
Battery is "heart" of every autonomous
system for supplying and is necessary to
dedicate the largest care at selection.


IMPORTANT NOTE!!!

It is clear that starting batteries which are used for trucks and cars, do not nearly satisfy needs in solar systems.

Cyclic mode operation, is normal in systems for supplying from renewable energy sources, drastically reduces lifetime of carbatteries.
