## 4. Key Turnkey Solar Economics (Utah 2026)
- Average Turnkey Solar Cost: $2.80 - $3.10 per Watt DC
- Average 13.5kWh LFP Battery Cost: ~$11,500 turnkey installed
- 30% Federal IRC Section 25D Tax Credit: Deducts 30% of total system and battery cost
- Payback with Solar + Battery: 7.2 to 8.8 years
- Payback Solar Only (under Schedule 136 export reduction): 11.5 to 13.0 years
- Conclusion: Storing surplus solar in a battery to avoid Tier 2 summer utility rates (14.28¢) beats raw grid export (5.25¢) by over 170%.
