The Bottom Line
Oklahoma City solar is a long-term play. With 16-20 year paybacks, this isn't a quick return market. But for homeowners planning to stay long-term, solar still makes sense over a 25+ year system lifetime.
Key considerations:
- Low electricity rates mean slow payback
- No federal credit for purchased systems hurts economics
- PPA/Lease may be better option (still gets 30% credit)
- Hail-resistant panels are worth the premium
- Best for: long-term homeowners, environmentally motivated
- 25-year perspective: rates will rise, system keeps producing
