Is Solar Worth It in Utah? A Comprehensive Analysis for 2025
As a Utah homeowner contemplating solar energy in 2025, it's essential to conduct a thorough evaluation of the financial and practical aspects involved. Recent developments in utility rates, state incentives, and net metering policies have significantly influenced the cost-effectiveness of residential solar installations.
This comprehensive analysis aims to provide detailed insights into these factors to help you make an informed decision.
Rocky Mountain Power Rates: Current and Proposed Increases
Rocky Mountain Power (RMP), Utah's primary electricity provider, has implemented and proposed rate adjustments that directly impact the financial viability of residential solar investments.
Current Rates (Effective July 1, 2024)
Customer Charge: $10.00 per month
Energy Charge (June through September):
First 400 kWh: 9.0279 cents per kWh
Additional kWh: 11.7210 cents per kWh
Energy Charge (October through May):
First 400 kWh: 7.9893 cents per kWh
Additional kWh: 10.3725 cents per kWh
Proposed Rate Increase
In August 2024, RMP proposed a substantial rate increase of 30.6% over two years. Following public feedback, the proposal was amended to an 18.1% increase, scheduled to take effect on February 23, 2025.
This adjustment is expected to raise residential electricity rates significantly, thereby affecting the cost-benefit analysis of installing solar panels.
Utah Solar Incentives: Phasing Out State Support
State incentives have historically played a crucial role in making solar installations more affordable for Utah homeowners. However, these incentives are undergoing significant changes.
Utah Renewable Energy Systems Tax Credit (RESTC)
Expiration: The RESTC, which provided a state tax credit for residential solar installations, expired on December 31, 2023. Consequently, homeowners installing solar systems in 2025 are no longer eligible for this state tax credit.
Federal Solar Tax Credit
Current Status: The federal Investment Tax Credit (ITC) allows homeowners to deduct 30% of their solar installation costs from their federal taxes. This credit is available for systems installed through 2032, offering some financial relief despite the absence of state incentives.
Net Metering Policies: Reduced Compensation for Excess Energy
Net metering policies determine how homeowners are compensated for the excess energy their solar systems generate and feed back into the grid. Recent changes have reduced these financial benefits, impacting the overall return on investment for solar installations.
Export Credit Rates
Current Rates: As of 2025, RMP compensates excess solar generation at an "avoided cost" rate of approximately 3 cents per kWh, which is significantly lower than the retail electricity rate. This reduction in compensation diminishes the financial incentives for homeowners to invest in solar systems.
Financial Analysis: Assessing the Viability of Solar Investments
To determine whether investing in solar is financially prudent in 2025, it's essential to conduct a detailed financial analysis considering the factors mentioned above.
Example Scenario
System Size: 6 kW
Annual Production: Approximately 8,000 kWh
Installation Cost: $18,000
Federal Tax Credit (30%): $5,400
Net Cost: $12,600
Annual Savings:
Self-Consumed Energy: Assuming 70% self-consumption (5,600 kWh) at an average rate of 10 cents per kWh:
Savings: $560
Excess Energy Exported: Remaining 2,400 kWh exported at 3 cents per kWh:
Credit: $72
Total Annual Savings: $632
Payback Period:
Net Cost: $12,600
Annual Savings: $632
Estimated Payback Period: Approximately 20 years
Given that the typical lifespan of solar panels is around 25 to 30 years, a 20-year payback period offers limited time for net savings. Additionally, potential maintenance costs and system degradation over time could further impact financial returns.
Additional Considerations: Maintenance, System Degradation, and Market Dynamics
Beyond the straightforward financial calculations, several other factors can influence the decision to invest in solar energy.
Maintenance Costs
Regular Maintenance: While solar panels require minimal maintenance, periodic cleaning and inspections are necessary to ensure optimal performance.
Inverter Replacement: Inverters typically need replacement every 10 to 15 years, costing between $1,000 and $2,000.
System Degradation
Performance Decline: Solar panels experience a gradual decrease in efficiency, typically around 0.5% per year, leading to reduced energy production over time.
Market Dynamics
Technological Advancements: Rapid advancements in solar technology could render current systems less efficient or obsolete, potentially affecting the system's value and performance.
Property Value Impact: While solar installations can increase property value, the extent varies based on market conditions and buyer perceptions.
Conclusion: A Cautious Approach to Solar Investment in 2025
In 2025, the financial case for residential solar in Utah is weaker than in previous years due to rising utility rates, reduced net metering compensation, and the expiration of state incentives.
Key Takeaways:
Higher Utility Rates: Rocky Mountain Power's proposed 18.1% rate increase means customers will pay more for grid electricity, but solar users will see fewer benefits due to reduced net metering rates.
Lower Compensation for Excess Energy: The 3-cent per kWh export credit is significantly lower than the 9-12 cent per kWh retail electricity rate, reducing the financial advantage of feeding excess energy back to the grid.
Long Payback Periods: The estimated 20-year payback period makes solar a less attractive investment, especially when considering maintenance costs and system degradation over time.
No State Incentives: The expiration of the Utah Renewable Energy Systems Tax Credit removes a financial cushion that previously made solar more affordable.
Who Should Still Consider Solar?
While the financial return for grid-tied solar has weakened, certain homeowners may still find value in solar under specific conditions:
Energy Independence Seekers
If you prioritize resilience and backup power, solar with battery storage can reduce dependence on the grid.
However, batteries add significant upfront costs, making financial ROI even less attractive.
High Energy Consumers
Households with high monthly electricity usage may see faster savings, especially if they can maximize self-consumption (instead of exporting excess power to the grid).
Long-Term Homeowners
If you plan to stay in your home for 25+ years, you may still see eventual cost savings—albeit at a much slower rate than before.
Environmental Motivations
If your primary goal is reducing carbon emissions rather than financial savings, solar still provides clean energy benefits.
Alternative Energy-Saving Strategies for Utah Homeowners
If the numbers don’t add up for solar, consider other energy efficiency solutions that can provide quicker returns:
Home Energy Audits: Identify energy waste and implement cost-effective improvements.
Smart Thermostats: Reduce heating and cooling costs with automated adjustments.
High-Efficiency Appliances: Upgrade to Energy Star appliances to lower electricity usage.
Insulation and Weatherproofing: Improve home insulation to cut heating and cooling expenses.
Demand Response Programs: Enroll in utility programs that offer bill credits for reducing electricity use during peak hours.
Final Verdict: Is Solar Worth It in Utah in 2025?
For most Utah homeowners, solar is no longer a strong financial investment.
The combination of increased grid rates, lower export credits, and no state incentives has significantly weakened the return on investment.
A 20-year payback period does not make financial sense for many homeowners, especially those who may sell their homes before breaking even.
Alternative energy-saving strategies may provide better cost savings with a faster return on investment.
The Bottom Line:
If you’re considering solar in Utah, run the numbers carefully before making a decision. For many homeowners, it simply doesn’t make financial sense in 2025. However, if your primary goal is energy independence or environmental impact, solar may still be worth exploring—with realistic expectations. Is Solar Worth It in Utah?
