Solar battery costs are widely varied and are higher for more significant batteries.  Smaller lead-acid batteries can be purchased for as little as $200. Lithium-ion battery costs range from $7,000 to $14,000. Costs are also determined by kWh. For example:
$4,500-9,600 for 6kWh
$9,800-14,000 for 10kWh
$8,000-18,000 for 13kWh
These costs are for the batteries only. Installation is an added expense. PPM Solar’s experts can help you through the decision process to ensure you get the size battery needed for your business.
