Wisconsin homeowners are increasingly pairing solar panels with battery storage as technology improves and concerns about power outages, utility costs and grid reliability grow. Although the expense of a fully off-grid system once discouraged many prospective buyers, homeowners are now approaching battery storage with more practical expectations.
JD Smith, director of marketing and public relations at Milwaukee-based Arch Solar, explained that about six years ago, roughly one in four customers asked about installing enough solar and storage to disconnect entirely from the electric grid. Interest often disappeared when customers learned that such a system could cost more than $50,000. Today, however, homeowners are less focused on achieving complete energy independence and more interested in maintaining essential power during shorter outages. Smith said at least half of Arch Solar’s customers now choose to include batteries with their projects.
This shift reflects the growing role of solar-plus-storage as a household resilience tool rather than a luxury. A battery can keep lights and critical appliances running during blackouts, protect refrigerated food and medications, and reduce a homeowner’s dependence on an increasingly strained grid. These benefits are becoming more important as electricity demand rises, particularly from large energy users such as data centers.
Emma Heins, a principal at Advanced Energy United, noted that renewable energy is among the fastest and least expensive forms of generation to add to the electric grid. Despite recent reductions in federal clean-energy incentives, technological improvements and strong consumer demand are helping the industry continue growing.
Wisconsin homeowners may also benefit from two programs funded through earlier Inflation Reduction Act allocations. The Home Efficiency Rebates, or HOMES, program offers up to $10,000 for qualifying efficiency improvements. The Home Electrification and Appliance Rebates, or HEAR, program provides up to $14,000 to qualifying low- and moderate-income households. The funding is expected to remain available through 2031, helping residents lower utility costs and plan larger home-energy upgrades.
