Why Utah Is a Solar Paradox: Cheap Electricity, Abundant Sunshine
Utah presents a solar paradox: it has some of the cheapest electricity in America (average $0.11/kWh, according to the U.S. Energy Information Administration (EIA)), yet it also has excellent solar resources (300+ sunny days per year, high elevation that increases panel efficiency).
As of 2026, Utah ranks 15th in the United States for total installed solar capacity, according to the Solar Energy Industries Association (SEIA). The state has over 2,500 MW of installed solar, enough to power more than 350,000 homes.
The primary challenge for Utah solar is not technical (the sun shines abundantly) but economic: cheap electricity means solar savings accumulate more slowly than in high-rate states like California or New York. However, Utah's low installation costs ($2.62/watt vs. $2.86/watt national average) and abundant sunshine (1,400–1,600 kWh/kW/year) make solar economical for many homeowners.
Understanding Utah's Electricity Rates in 2026
Utah's electricity is cheap primarily because of the state's abundant natural gas resources and Rocky Mountain Power's diversified generation mix (30% coal, 25% natural gas, 20% hydroelectric, 15% solar/wind, 10% other). As of 2026, Rocky Mountain Power's residential rate is approximately $0.105–$0.115/kWh, depending on the rate schedule.
Rocky Mountain Power's Residential Rates
Rocky Mountain Power (a subsidiary of PacifiCorp) serves approximately 1.2 million customers in Utah. Their standard residential rate schedule (Schedule 1) has:
- Basic charge: $6.00/month (fixed, regardless of usage)
- Energy charge: $0.105/kWh for the first 400 kWh, $0.115/kWh for usage above 400 kWh
- Typical bill: A household using 900 kWh per month pays about $95–$105 (including the basic charge and taxes).
Time-of-Use (TOU) option: Rocky Mountain Power offers an optional TOU rate that charges higher rates during peak hours (5–9 PM weekdays) and lower rates at night and on weekends. For solar owners who use electricity in the evening, this rate can be advantageous if paired with battery storage.
Utah's Net Metering Policy: What Changed in 2017
Utah ended traditional net metering in 2017 for new solar customers. This was a significant policy change that affected the economics of solar in the state. Here's what you need to know:
Before 2017: Full Retail Net Metering
Before 2017, Utah solar owners received full retail rate credits (approximately $0.11/kWh) for excess solar exported to the grid. This made solar highly economical, with payback periods of 8–10 years.
After 2017: Wholesale Export Credit ("Future Cost-Based Rate")
New solar customers after 2017 are placed on a "future cost-based rate" that credits excess solar at approximately $0.05–$0.07/kWh (wholesale rate), not the full retail rate. This means:
- When your solar panels produce more than your home uses, the excess is sent to the grid and you receive a credit at ~$0.06/kWh.
- When your panels aren't producing (at night), you draw electricity from the grid and pay the full retail rate (~$0.11/kWh).
- This creates a "sell low, buy high" situation that reduces the financial benefits of grid-tied solar.
Why Utah ended net metering: Rocky Mountain Power argued that net metering customers were not paying their fair share of grid maintenance costs, shifting those costs to non-solar customers. The Utah Public Service Commission approved the change after lengthy proceedings.
How Utah's Policy Compares to Neighboring States
| State | Net Metering Policy (2026) | Export Credit Rate |
|---|---|---|
| Utah | Wholesale rate (ended retail net metering in 2017) | ~$0.05–$0.07/kWh |
| Colorado | Full retail net metering (Xcel Energy) | ~$0.13/kWh |
| Nevada | Revised net metering (SB 392) | ~$0.08–$0.10/kWh |
| Arizona | Resource Comparison Proxy (RCP) – varies by utility | ~$0.07–$0.09/kWh |
Why Battery Storage Is More Attractive in Utah
Because Utah's net metering policy credits excess solar at wholesale rates ($0.05–$0.07/kWh) while charging full retail rates ($0.11/kWh) for grid electricity, battery storage can be economically advantageous in Utah:
- Self-consumption: Store excess solar during the day, use it at night. This avoids the "sell low, buy high" penalty of net metering.
- Time-of-Use arbitrage: Charge battery at night (off-peak rate), discharge during peak hours (5–9 PM) to avoid high TOU rates.
- Backup power: Utah experiences occasional winter storms that can cause outages. Battery storage provides backup power.
Cost consideration: As of 2026, a Tesla Powerwall+ (13.5 kWh) costs approximately $11,500 installed in Utah. With the 30% federal tax credit, the net cost is $8,050. For many Utah homeowners, the payback period for battery storage is 12–18 years, which may be acceptable if you value backup power and energy independence.
Utah Solar Incentives in 2026
Unlike some states (such as California, New York, or Massachusetts), Utah offers no state tax credit or rebate for solar installation. However, you can still benefit from:
1. Federal Tax Credit (30%)
The 30% federal Investment Tax Credit (ITC) applies to Utah solar installations, reducing the cost of a typical 7 kW system from $18,340 to $12,838.
2. Property Tax Exemption
Utah law (Utah Code § 59-2-402) exempts 100% of the added value of a solar energy system from property taxation. This saves approximately $120–$250 per year in property taxes (assuming a 1–1.5% property tax rate and a $15,000 system value).
3. Sales Tax Exemption
Solar energy equipment purchased for use in Utah is exempt from state sales tax (currently 4.85%, plus local sales taxes that can bring the total to 6.1–8.35%). This saves approximately $1,100–$1,500 on a typical 7 kW system.
4. Rocky Mountain Power's Sustainable Solar Program
Rocky Mountain Power previously offered a sustainable solar program that provided technical assistance and streamlined interconnection. As of 2026, this program has transitioned to a standard interconnection process. Check with Rocky Mountain Power for the latest details.
Real-World Case Study: Mark's 8 kW System in Salt Lake City, UT
To illustrate what a typical Utah solar installation looks like, here's a case study based on a real homeowner (name changed for privacy):
Mark's situation (Salt Lake City, UT – Rocky Mountain Power territory):
- Home: 2,800 sq ft single-family home built in 2000
- Monthly electricity bill: $105 (950 kWh per month)
- Roof: South-facing, 6/12 pitch, minimal shading
- System installed (April 2026): 8 kW (22 × 365W panels)
- Total cost: $20,960 ($2.62/watt)
- After federal tax credit (30%): $14,672
First 4 months of production (April–July 2026):
| Month | Solar Production (kWh) | Electricity Usage (kWh) | Net Grid Draw (kWh) | Bill After Solar |
|---|---|---|---|---|
| April 2026 | 1,120 | 880 | 0 (excess 240 kWh) | -$14.40 (credit)* |
| May 2026 | 1,280 | 920 | 0 (excess 360 kWh) | -$21.60 (credit)* |
| June 2026 | 1,350 | 1,050 | 0 (excess 300 kWh) | -$18.00 (credit)* |
| July 2026 | 1,310 | 1,180 | 0 (excess 130 kWh) | -$7.80 (credit)* |
* Note: These "credits" are at Rocky Mountain Power's wholesale export rate of ~$0.06/kWh, not the full retail rate. In winter, Mark will use these credits to offset his grid draw.
Mark's savings in the first 4 months:
- Without solar: $105 × 4 = $420
- With solar: $0 (Mark's system produced more than he consumed, but the export credits are at wholesale rates)
- Projected annual savings: $1,150–$1,300 (winter months will have some grid draw)
- Payback period: 11.3 years ($14,672 net cost ÷ $1,300 annual savings)
Mark's advice for Utah homeowners: "Don't expect solar to eliminate your electric bill completely in Utah. The wholesale export credit means you're better off sizing your system to cover 80–90% of your annual usage, not 100%. And consider battery storage if you want to maximize self-consumption."
Factors That Affect Your Solar Savings in Utah
1. System Size & Export Credits
Because Utah's export credits are at wholesale rates, oversizing your system is not economical. Aim to cover 80–90% of your annual consumption, not 100%+. The excess will be credited at $0.05–$0.07/kWh, which is a poor return on investment.
2. Roof Orientation & Snow
Utah's latitude (37–42°N) and high elevation (4,000–6,000 ft in population centers) mean that south-facing panels with a 30–40° tilt angle capture the maximum annual sunlight. However, Utah's winter snow can temporarily reduce production. Panels typically shed snow within 1–2 days of sunny weather (the dark panels absorb heat and melt snow), but prolonged snow cover can reduce winter production by 10–20%.
3. Rocky Mountain Power Rate Schedules
If you install battery storage, consider switching to Rocky Mountain Power's Time-of-Use (TOU) rate. This allows you to charge your battery at night (off-peak rate) and discharge during peak hours (5–9 PM), maximizing the value of your stored solar energy.
Utah Solar Installers: What to Look For
Utah has a competitive solar installation market, with over 150 licensed solar contractors operating in the state (Utah Division of Occupational and Professional Licensing, 2026). Key factors to consider:
- Utah contractor license – Ensure your installer has a valid Utah contractor license (S220 Solar PV specialty license or equivalent).
- Experience with Rocky Mountain Power interconnection – Utah's interconnection process can take 4–8 weeks. An experienced installer can streamline this.
- Battery storage expertise – Because Utah's net metering policy favors self-consumption, many Utah installers now offer integrated solar + storage solutions. Choose an installer certified by Tesla (for Powerwall) or Enphase (for IQ Battery).

Frequently Asked Questions About Solar in Utah
It depends on your priorities. If your goal is purely financial payback, battery storage in Utah has a long payback period (12–18 years). However, if you value energy independence, backup power during outages, and protection against future rate increases, battery storage can be worthwhile. The 30% federal tax credit reduces the net cost significantly. As battery prices continue to decline, payback periods will shorten.
Yes, but it's expensive. A typical off-grid system in Utah requires 10–15 kW of solar (to cover winter production) and 20–30 kWh of battery storage (to cover 2–3 days of cloudy weather). Total cost: $40,000–$60,000. Most Utah homeowners find that staying grid-tied (even with wholesale export credits) is more economical than going off-grid.
Utah law (Utah Code § 59-2-402) exempts 100% of the appraised value of a solar energy system from property taxation. This applies to both residential and commercial systems. Unlike some states (which require annual reapplication), Utah's exemption is automatic – you don't need to file any forms. The exemption applies to the solar equipment only, not to any increase in home value due to solar.
If you own your solar system (not leased), it transfers with the home when you sell. Studies show that homes with solar panels sell for 4–6% more than comparable homes without solar (Lawrence Berkeley National Laboratory, 2026). In Utah's competitive housing market, solar can be a significant selling point, particularly in the Salt Lake City, Provo, and St. George markets where electricity rates are higher.
