25-Year Electric Utility Inflation & Solar Wealth Simulator (2026)
Doing nothing about your electric bill is a guaranteed 25-year variable-rate liability. Use the interactive slider below to see how compounding utility rate hikes (2%–8%/yr) compare against owning a fair-priced solar + LFP battery system outright.

📈 WEALTH MATH FAQHow much does a $280/month electric bill actually cost over 25 years with utility rate inflation?
At the historical US utility rate inflation average of 4.5% per year, a $280/month electric bill does not cost $84,000 over 25 years—it compounds to $149,730 in cumulative payments to your electric utility, with your monthly bill reaching $805/month by Year 25. In high-inflation territories like California (PG&E, SDG&E, SCE) and the Northeast (ConEd, Eversource) where rates have risen 6%–8% annually, a $280/month bill exceeds $204,000 over 25 years.
📈 WEALTH MATH FAQWhy does paying Fair Cash or buying Direct Hardware move my breakeven crossover 7 years earlier?
When you sign a $42,500 solar loan inflated by 30% dealer fees, it takes 9 to 11 years just to recover the inflated principal. When you pay Fair Market Cash ($26,500) or source UL9540 hybrid battery hardware directly ($10,500), your breakeven crossover drops to 3.5 to 5.8 years—meaning you enjoy 19+ years of 100% tax-free electricity savings.
Skip the $14,000 Installer Markup: Direct-Purchase Hardware & Vetted Quotes
Turnkey solar salespeople routinely charge $3.60–$4.80/W by bundling 30% loan dealer fees and $12,000+ battery margins. Buying Tier-1 UL9540 hardware directly—either DIY or hiring a local licensed electrician ($1,500–$2,500)—cuts total cost by 50–65%.
