About Photovoltaic Energy StorageCapacity. A battery''s capacity measures how much energy can be stored (and eventually discharged) by the battery. While capacity numbers vary between battery models and manufacturers, lithium-ion battery technology has been well-proven to have a significantly higher energy density than lead acid batteries.
About Photovoltaic Energy StorageOlder lead-acid batteries were made from cast lead plates onto which a paste was loaded. These plates and separators were then stacked, generally with negative plates on both sides, so there was always one more negative plate than the positive plate. Batteries were often called 7-plate, 9-plate, or as many as 17-plate batteries.
