For Payson, Utah homeowners eyeing solar in 2025, battery storage is key to profitability and resilience—especially with expiring tax credits creating urgency. At Ask Solar Mike, we specialize in EG4 ESS and Tesla Powerwall 3 installations, helping families navigate Payson's 10kW system limits while maximizing savings. With Utah's Renewable Energy Systems Tax Credit (RESTC) ending for systems after 2025 per HB 264, and the federal Investment Tax Credit (ITC) at 30% but stepping down soon, now's the time to compare these top batteries. In this ultimate guide, we'll pit EG4 ESS against Tesla Powerwall 3, tailored for Payson and Utah County needs, to position you for optimal energy independence.
Understanding the Urgency: Expiring Solar Tax Credits in Utah for 2025
Utah's solar boom, fueled by 200+ sunny days and incentives, faces changes that demand action:
Federal ITC: 30% credit on solar and batteries through 2032, reducing to 26% in 2033 and expiring by 2035. For a $20,000 battery addition, that's $6,000 in savings—critical before potential shifts.
Utah State RESTC: Up to $400 extra, but it phases out post-2025 per legislation. Combined, Payson residents could save $8,000+ on systems—opportunities vanishing if you delay.
Google Trends shows a 50% rise in "Utah solar battery incentives 2025" searches, echoing inquiries from Payson, Salem, and Spanish Fork. Don't wait—get a free personalized quote at https://www.asksolarmike.com/google to lock in these benefits.
