Solar in Tulsa
Tulsa offers excellent solar production potential with 5.3 peak sun hours daily. However, Oklahoma's very low electricity rates mean the financial payback takes longer than in high-rate states. Solar in Tulsa is often driven by energy independence goals and long-term value.
Tulsa Solar Factors
- Excellent sunshine: 5.3 peak sun hours daily
- Very low rates: ~$0.10/kWh average
- Longer payback: 16-20 years typical
- Strong production: Great output per panel
- Tornado alley: Durability considerations
Tulsa Solar Costs
Average System Costs
| System Size | Gross Cost | Cost/Watt |
|---|---|---|
| 6 kW | $14,400-18,000 | $2.40-3.00 |
| 8 kW | $19,200-24,000 | $2.40-3.00 |
| 10 kW | $24,000-30,000 | $2.40-3.00 |
Federal 25D credit ended Dec 31, 2025. PPA/lease options still access 30% federal benefit.
Payback Timeline
- Purchased systems: 16-20 years typical
- With rising rates: Could improve to 14-18 years
- 25-year savings: $12,000-20,000 typical
- Best fit: Long-term homeowners
PSO (AEP)
Public Service Company of Oklahoma (PSO), an AEP company, serves most of Tulsa. Their net metering policy is a key factor in solar economics.
PSO Net Metering
| Feature | Details |
|---|---|
| Credit rate | Avoided cost (~$0.03-0.04/kWh) |
| System size limit | 25 kW residential |
| Credit rollover | Monthly, annual true-up |
| Overall rating | Less favorable than 1:1 states |
Utility Strategy
- Size appropriately: Match system to usage, not oversized
- Self-consumption: Use power during production hours
- Battery consideration: Can improve self-consumption
- Time shifting: Run appliances during sunny hours
Oklahoma Incentives
Available Incentives
- Property tax exemption: Solar improvements often exempt
- Net metering: Available but at avoided cost rates
- Interconnection: Relatively straightforward process
Limited State Support
Oklahoma has minimal state incentives for residential solar. The state's low electricity rates and oil/gas industry presence have limited solar policy development. This is a key factor in longer payback periods.
Federal Options
- Purchased systems: No federal credit (25D ended 2025)
- PPA/Lease: Solar company claims 30% credit through 2027
- Net benefit: Lower PPA rates reflect federal savings
Tulsa Considerations
Weather Factors
- Tornado season: April-June highest risk
- Hail storms: Panels rated for hail important
- Hot summers: Some efficiency loss on hottest days
- Four seasons: Winter production lower but consistent
Installation Considerations
- Hail rating: Look for panels tested for 1"+ hail
- Wind rating: Ensure proper mounting for Oklahoma winds
- Insurance: Verify solar coverage, especially for severe weather
- Roof condition: Address any issues before installation
Production Estimates
- Annual production: 1,400-1,600 kWh per kW installed
- 8 kW system: ~11,500-13,000 kWh/year
- Best months: April-September
- Winter production: 45-55% of peak
The Bottom Line
Tulsa has great sunshine but challenging economics. Very low electricity rates (~$0.10/kWh) and avoided-cost net metering create 16-20 year paybacks. Solar works best for those focused on energy independence and long-term value.
Key points:
- Excellent 5.3 peak sun hours for strong production
- Very low rates extend payback to 16-20 years
- PSO pays avoided cost, not retail, for exports
- Size system to match usage, not over-produce
- Best for long-term homeowners and energy independence
