Energy Storage System Buyer''s Guide 2022. By SB Staff August 8, 2022. Energy storage systems (ESS) are increasingly being paired with solar PV arrays to optimize use of the generated energy. ESS, in turn, is getting savvier and feature-rich. Batteries can be smartly deployed to maximize ROI.
A solar-plus-storage system costs about $25,000–$35,000, depending on the size of the battery and other factors. It is easier and cheaper to install the panels and battery at the same time. But if you''ve already installed solar panels and want to add storage, you can: The battery will cost anywhere from $12,000 to $22,000.
