The origins of “solar + storage” came from the earliest combinations of photovoltaic modules, power electronics, and lead-acid batteries used exclusively in the domain of what we now categorize as off-grid solar. With rapid advances in those core technologies, the applications for energy storage have broadened significantly, and energy storage is now central to solutions ranging from utility-connected residential systems to micro-grids providing reliable power for rural electrification.

Residential Off-Grid Solar Batteries

Store energy generated by on-site renewables to support autonomous living or small commercial and farming operations without a connection to the electric utility grid.

Whole-Home Backup Batteries

Store energy to power your home during blackouts or weather-related grid outage and enable self-consumption of renewable energy to avoid peak period utility rates.

Rural Microgrid Batteries

Large capacity energy storage combined with localized generation to create an autonomous electric grid that will support a farm, resort, commercial operation, or multiple residences.

Utility Surcharge Avoidance Batteries

Store on-site renewable and electrical grid energy during times of low demand and low utility rates for consumption later avoiding peak period surcharges.

Battery Comparison & Cost Calculator

Having difficulty explaining the real cost of energy storage options in a way your customers can understand? Discover’s Energy Storage Cost Calculator is a tool for installers that compares CAPEX vs OPEX of the major storage chemistries used in off-grid solar over a 10-year period.

Compare AES lithium to other lithium, tubular or lead acid battery systems. All you need is the manufacturer’s data sheet and battery specifications. Discover’s Energy Storage Cost Calculator generates a printable report that will help you demonstrate the impact of battery chemistry choice on your customer’s total cost of energy storage.
