    Bigger Than Batteries: Why the Cost of Other Components Matters to Storage Deployment

    When it comes to energy storage systems, the cost of the battery itself receives a great deal of attention, but a new report shows that the plummeting price of other storage components could prove just as significant for the proliferation of the resource. The 15 to 20 different items in the balance of the system (BOS) represent one-half to three-fourths of the installation’s cost. Those costs are likely to plummet over the next five years – if the growth of storage deployment continues.
