Solar Panel Payback Calculator for Wyoming
Wyoming (WY) offers excellent solar potential with an average of 5 peak sun hours per day. The average residential electricity rate is 11 cents per kWh, and solar installation costs average $3.00 per watt. Based on these figures, a typical 6 kW residential solar system in Wyoming has an estimated payback period of 13.1 years and generates $20,251 in total savings over 25 years.
Solar System Size Comparison for Wyoming
The table below compares four common residential solar system sizes for Wyoming homeowners. All calculations use the state average electricity rate of 11 cents per kWh, average installation cost of $3.00/W, and 5 peak sun hours. The federal 30% Investment Tax Credit is included in all scenarios.
| System Size | Gross Cost | Federal Credit | Net Cost | Annual Output | Annual Savings | Payback | 20-Year Savings | 25-Year Savings |
|---|---|---|---|---|---|---|---|---|
| 4 kW | $12,000 | $3,600 | $8,400 | 5,840 kWh | $642 | 13.1 years | $7,985 | $13,500 |
| 6 kW | $18,000 | $5,400 | $12,600 | 8,760 kWh | $964 | 13.1 years | $11,978 | $20,251 |
| 8 kW | $24,000 | $7,200 | $16,800 | 11,680 kWh | $1,285 | 13.1 years | $15,970 | $27,001 |
| 10 kW | $30,000 | $9,000 | $21,000 | 14,600 kWh | $1,606 | 13.1 years | $19,963 | $33,751 |
Solar Energy in Wyoming: What You Need to Know
Wyoming has good sun hours, especially in the southern part of the state, but very low electricity rates. No state income tax precludes a state tax credit. Wind dominates Wyoming's renewable energy.
Electricity Rates in Wyoming
The average residential electricity rate in Wyoming is 11 cents per kWh, which is below the national average of approximately 16 cents per kWh. Lower electricity rates mean the payback period is longer, but the 25-year savings are still substantial. As electricity rates continue to rise (averaging 3% per year nationally), the value of solar ownership increases over time.
Peak Sun Hours and Solar Production
Wyoming averages 5 peak sun hours per day, which is a solid level for residential solar. While not the sunniest state, the combination of decent sun hours with modern high-efficiency panels produces meaningful electricity savings throughout the year. A 6 kW system in Wyoming produces approximately 8,760 kWh per year, accounting for standard system efficiency losses and typical weather patterns.
Wyoming Solar Incentives and Programs
No state income tax, so no state tax credit. Net metering available through Rocky Mountain Power. No sales tax exemption for solar. Property tax exemption for renewable systems. Low electricity costs extend payback.
Incentive Summary for Wyoming
- Federal Tax Credit: 30% ITC (available through 2032)
- State Tax Credit: None
- Net Metering: Available
- SRECs: Not available
- Avg. Installation Cost: $3.00/watt (before incentives)
How Wyoming Compares to Similar States
Below is a comparison of Wyoming with five states that have similar solar conditions. All calculations are based on a 6 kW residential system using each state's average electricity rate and sun hours.
| State | Sun Hours | Rate (c/kWh) | Cost/Watt | Net Cost | Payback | 25-Yr Savings |
|---|---|---|---|---|---|---|
| Wyoming | 5 | 11c | $3.00 | $12,600 | 13.1 years | $20,251 |
| Oklahoma | 5 | 11.5c | $2.85 | $11,970 | 11.9 years | $22,374 |
| Texas | 5 | 13c | $2.70 | $11,340 | 10.0 years | $27,483 |
| Florida | 5.2 | 13.5c | $2.65 | $11,130 | 9.0 years | $30,797 |
| Kansas | 4.8 | 13.5c | $2.90 | $12,180 | 10.7 years | $26,526 |
| Louisiana | 4.8 | 10c | $2.85 | $11,970 | 14.2 years | $16,701 |
Environmental Impact of Solar in Wyoming
Installing a 6 kW solar system in Wyoming offsets approximately 7,490 pounds of CO2 per year, which is equivalent to planting 61.8 trees annually. Over the 25-year lifespan of your solar system, that adds up to roughly 187,250 pounds of avoided carbon emissions. Choosing solar energy is one of the most impactful steps a homeowner can take to reduce their carbon footprint and contribute to cleaner air in Wyoming communities.
