Full transparency Missouri solar payback math after the federal residential ITC expired Dec 31, 2025 under OBBBA. Walks through 4 scenarios (8 kW, 10 kW, 12 kW Ameren MO + 10 kW Columbia W&L) with line-item math: gross cost, 25% Midas Wealth check, year-1 savings, 25-year compounded savings. Typical Ameren MO scenario: $20,250 net out-of-pocket, $2,020 year-1 savings, ~9-year simple payback, $58,595 net 25-year benefit. Includes RSMo 386.890 net metering math and battery economics breakdown.
The honest Kansas counterpart to the Missouri payback page. Kansas runs ~1 to 2 years slower than Missouri, not because of rates (Kansas is slightly higher at 15.25¢/kWh) but because K.S.A. 66-1263 (as amended by HB 2527 in 2024) credits excess kWh at ~2.4¢ wholesale system-average rather than retail. Walks through 4 scenarios (6 kW Overland Park, 10 kW Lenexa typical, 12 kW Wichita, 10 kW + Franklin battery): typical 10 kW system $20,250 net, $1,709 year-1 savings, ~10.1-year payback, $46,000 net 25-year benefit. Right-sizing matters more in Kansas than Missouri. Battery economics noted (~26-yr alone, outage protection only). Plus K.S.A. 79-201 Eleventh 10-year property tax exemption explained.
The Tier 1 decision page that complements the Missouri payback math. Where the payback page does the calculation, this page does the decision: should you even pursue solar? Walks through the 5-question screening test (own home, 5+ year horizon, decent roof, 800+ kWh per month, OK with Midas Wealth structure), 7 specific YES scenarios (Ameren MO household with rate exposure, Columbia W&L with $5K rebate active, all-electric home, long horizon, Evergy MO TOU, HOA-protected post-Eikmeier, household without federal tax appetite), 5 specific NO scenarios (selling within 3 yrs, heavily shaded roof, under 600 kWh/mo, roof replacement coming, high-interest debt). Calls out the post-ITC reality most competitor pages still ignore. References Wave 7 Missouri Payback for the math.
Eight honest scenarios where rooftop solar typically does not make sense for a Missouri or Kansas homeowner, written by an installer who would rather lose business than sell to people for whom the math does not work. Covers planning to move, roof age, shade, low bills, renting, high-interest debt, weak net metering, and pending home upgrades.
