Dependable Commercial Storage
Battery storage is not simply an add-on to solar—it is a flexible energy management tool that can strengthen a company’s electrical strategy.
A battery system can store electricity when it is less expensive or when a solar array is producing more than the facility needs. That energy can then be used during periods of high demand, helping businesses reduce demand charges and avoid drawing as much power from the grid when rates are highest.
Energy storage also improves resilience. When designed for backup capability, batteries can support critical equipment during an outage, helping businesses protect operations, inventory, data, and essential services. The level of backup depends on the facility’s electrical loads, operational priorities, and system design.
Storage can also help businesses use more of the renewable energy produced on-site while supporting sustainability and carbon-reduction goals. As utility rates, grid constraints, and energy needs continue to change, batteries provide flexibility.
Arch Solar evaluates energy usage, demand patterns, solar production, utility rates, and resilience goals to determine whether storage makes financial and operational sense for each customer.

What is BESS?
BESS stands for Battery Energy Storage System, a technology that stores electricity generated by solar panels for later use. It allows businesses to use stored solar energy when utility rates are high, during periods of peak demand, or as backup power during an outage.
Commercial Battery Storage FAQs
Do commercial batteries get a federal tax incentive?
YES. The battery tax credit is maintained through 2032.
Can I use my commercial battery to generate revenue?
Yes, programs in other states are already active, so Wisconsin businesses will likely see this option in the next few years.
What is the useful life of a battery?
Products are under warranty for a promised number of cycles, or 10 years. Your longevity depends on battery use and cycling.
Where are batteries located?
Commercial storage is typically installed outside, near the main electrical service.
Fire code for commercial batteries requires substantial costs to locate the unit inside a building.
Commercial batteries are rated for outdoor use and have onboard heating and cooling.
How does the battery control system decide when to charge, discharge, or operate?
Each system has a PCS (Power Control System) that functions as the “brain” of the battery and is programmable.
Will the battery provide power during a grid outage?
In some cases, yes. Some manufacturers have off-grid capability as a built-in standard, while other providers can add this feature for an extra cost.
What does the financial return look like?
Unlike solar, battery performance depends on how YOU use power and energy.
Structuring your energy use with strategic backup can have a great financial return.

Solar paired with battery energy storage can help a business maintain operations around the clock by producing electricity during the day and storing excess energy for use at night, during peak-demand periods, or when grid power is unavailable.
During a power outage, a properly designed solar-plus-storage system can automatically supply electricity to selected critical loads. Depending on the system’s size and design, this may include lighting, communications, refrigeration, security systems, computers, production equipment, or other essential operations.
Businesses can also combine solar and batteries with a generator or other backup source to support longer outages and create a more resilient energy system.
Arch Solar evaluates a facility’s energy usage, critical equipment, available space, utility rates, and outage risks to design an appropriate solution.
