North Dakota Solar Incentives 2026: Xcel & MDU Net Metering, Property Tax Exemption & REAP

North Dakota's solar story is one of contrasts: among the lowest electricity rates in the nation, yet meaningful property tax relief, solid net metering from its two investor-owned utilities, and a standout Energy Community bonus ITC in its coal-power counties that can trim payback to 10–11 years. For the state's enormous agricultural sector — North Dakota is a top-five producer of corn, soybeans, sunflowers, and cattle — the USDA REAP grant program is arguably the most powerful solar incentive in the entire country, enabling farm paybacks of just 3–5 years even at these low electricity rates.

North Dakota does not have a current state income tax credit for solar (the previous credit expired), and it does not exempt solar equipment from its 5% sales tax. Those gaps matter and add $1,000–$1,500 to a typical residential system's cost compared to sales-tax-exempt states. But with a 5-year property tax exemption under state law, retail-rate net metering from Xcel Energy (Northern States Power) and Montana-Dakota Utilities, and the federal 30% ITC available to every buyer, North Dakota residents can build a solid solar case — particularly those in Energy Community-designated coal counties or agricultural operations eligible for REAP.

Federal Solar Tax Credit: 30% Standard, 40% in Energy Community Counties

The federal Investment Tax Credit (ITC) is the cornerstone of solar economics in North Dakota. The standard 30% nonrefundable credit applies to the full installed cost of your solar system — panels, inverter, racking, wiring, monitoring equipment, and any co-installed battery storage — in the year the system is placed in service.

For the average North Dakota homeowner:

System Size	Gross Cost	ITC (30%)	Net Cost After ITC
7 kW	$20,300	$6,090	$14,210
9 kW	$26,100	$7,830	$18,270
11 kW	$31,900	$9,570	$22,330
13 kW	$37,700	$11,310	$26,390

The ITC is nonrefundable — it reduces your federal income tax bill dollar-for-dollar, but does not generate a refund if your credit exceeds your liability. Most North Dakota homeowners and farm operators have sufficient federal tax liability to absorb the full credit in year one, though farmers with variable income may need to carry unused credit forward (the ITC can carry forward up to 20 years).

Energy Community 40% ITC: The Standout Opportunity in North Dakota

North Dakota's coal power legacy qualifies several counties for the Energy Community 40% ITC — a 10-percentage-point bonus over the standard rate that can make the difference between a marginal solar investment and a strong one. This is the most significant solar incentive enhancement available to North Dakota buyers, and it's underutilized because many residents in these counties don't know they qualify.

Qualifying Energy Community counties in North Dakota:

• Oliver County — home to the Coal Creek Station (one of the largest coal plants in the upper Midwest; under energy transition), Stanton area
• McLean County — coal mining and power generation supply chain employment history
• Mercer County — Antelope Valley Station (coal-fired power), Beulah area
• Billings County — fossil fuel employment history; western North Dakota oil and coal heritage
• Portions of Adams County — verify specific census tract eligibility at the IRS Energy Community lookup tool

For a 10 kW system at $29,000:

• Standard 30% ITC: saves $8,700 → net cost $20,300
• Energy Community 40% ITC: saves $11,600 → net cost $17,400 (saves $2,900 more)

That $2,900 additional savings translates directly to a faster payback — approximately 1.5–2 fewer years in a typical rural North Dakota scenario. If you live in or near Beulah, Hazen, Stanton, Killdeer, or the Billings County area, verify your eligibility before contracting for solar. The federal solar tax credit guide explains how to claim the Energy Community bonus and what documentation is required.

North Dakota 5-Year Property Tax Exemption (NDCC § 57-02-09.1)

Under North Dakota Century Code § 57-02-09.1, solar energy equipment is exempt from property taxation for five years from the date of installation. This exemption:

• Covers 100% of the assessed value attributable to the solar system
• Lasts 5 years (shorter than Montana's 10-year exemption, but still meaningful)
• Applies to residential and commercial systems
• Must be applied for — it is not automatic. File an application with your county assessor after installation

How much does this save? North Dakota's average effective property tax rate is approximately 0.98%–1.05%, slightly above the national average. For a home where a solar system adds $18,000–$26,000 in assessed value:

Solar System Value Added	ND Property Tax Rate	Annual Savings	5-Year Total
$18,000 (7 kW)	1.0%	$180/year	$900
$23,000 (9 kW)	1.0%	$230/year	$1,150
$26,000 (10 kW)	1.0%	$260/year	$1,300
$30,000 (12 kW)	1.0%	$300/year	$1,500

A $1,000–$1,500 reduction in net system cost from the property tax exemption meaningfully offsets the sales tax that North Dakota does charge. Contact your county assessor's office within 60 days of installation to file the exemption.

No State Income Tax Credit — What Happened?

North Dakota previously offered a state income tax credit for solar installations, but that credit has expired and is no longer available for new installations as of 2026. This puts North Dakota behind neighbors like Minnesota, which offers utility rebate programs and additional state-level support through Xcel Energy's Solar*Rewards program. It's an honest gap in North Dakota's incentive stack, and buyers should not factor any state income tax credit into their financial models.

No Sales Tax Exemption — An Important Cost Adder

Unlike Montana (no sales tax at all) or Minnesota (which exempts solar equipment from sales tax), North Dakota charges its full 5% state sales tax on solar equipment and installation. For a typical residential installation:

System Size	Equipment + Labor (Est.)	ND 5% Sales Tax	Impact
7 kW	$20,300	~$1,015	Adds to gross cost
9 kW	$26,100	~$1,305	Adds to gross cost
11 kW	$31,900	~$1,595	Adds to gross cost

The silver lining: the federal ITC applies to the total installed cost including sales tax, so you do recover 30% of the sales tax through the ITC. But compared to Montana or Minnesota buyers, a North Dakota resident pays roughly $700–$900 more in net after-ITC cost due to sales tax. Factor this into your comparison shopping.

North Dakota Net Metering: Xcel Energy and Montana-Dakota Utilities

The North Dakota Public Service Commission (NDPSC) mandates retail-rate net metering for the state's investor-owned utilities. The two IOUs serving North Dakota are:

Xcel Energy (Northern States Power — NSP)

Service territory: Northwestern North Dakota, the Fargo metro area, and adjacent portions of southeastern North Dakota. Xcel/NSP is one of the largest utilities in the upper Midwest and a familiar brand across the region.

Xcel NSP Net Metering Terms:

• Monthly netting at the full retail rate
• Accumulated credits carry forward month to month at retail rate
• Annual true-up: April and October settlement — any remaining accumulated credit is settled at the avoided cost rate (~$0.03–$0.05/kWh), significantly below the retail rate
• Residential rate: approximately $0.10–$0.12/kWh (among the lowest in the nation)

Sizing implication: This true-up structure is critical for Xcel/NSP customers in North Dakota. A system sized to produce 15% more than your annual consumption will see that 15% valued at $0.03–$0.05/kWh at true-up rather than $0.10–$0.12/kWh at retail. The gap between retail ($0.11) and avoided cost ($0.04) is enormous — don't oversize. Target annual production equal to or slightly below your annual consumption. Use the solar payback period calculator to model this carefully.

Montana-Dakota Utilities (MDU)

Service territory: Central and eastern North Dakota — Bismarck, Minot, Dickinson, and extending into the Grand Forks region. MDU is a major multi-state utility serving the Dakotas and surrounding states.

MDU Net Metering Terms:

• Monthly netting at retail rate
• Annual true-up in April and October at avoided cost for surplus credits
• Residential rate: approximately $0.11–$0.13/kWh — modestly higher than Xcel/NSP
• MDU's slightly higher rate makes solar marginally more economical in Bismarck and Minot compared to Fargo

MDU's rates have trended upward in recent years, which gradually improves the economics of solar investments made today. A system installed at 2026 rates will be increasingly valuable as MDU rates continue rising through the 2030s and 2040s.

Rural Electric Cooperatives: No Net Metering Mandate

This is a critical point for rural North Dakota buyers: the NDPSC net metering mandate does not apply to rural electric cooperatives served at wholesale by Basin Electric Power Cooperative or Minnkota Power Cooperative.

Rural electric cooperatives in North Dakota — which serve a large portion of the state's geographic area — operate under their own policies. Some offer net metering voluntarily; others do not, or compensate exported solar at avoided cost only with no retail-rate netting benefit.

Before going solar if you're served by a rural cooperative, call your co-op and ask:

1. Do you offer net metering for residential or farm solar installations?
2. What rate do you pay for excess solar exported to the grid?
3. Are there interconnection fees, standby fees, or system size caps?
4. Is your co-op served by Basin Electric or Minnkota at wholesale?

The answer to these questions will fundamentally determine whether residential solar is economically viable at your location. Some Basin Electric co-ops have moved toward adopting net metering programs voluntarily; verify with your specific co-op.

USDA REAP: The Most Powerful Incentive for North Dakota Farms

For North Dakota's agricultural community — the state ranks among the top producers in the nation for durum wheat, sunflowers, canola, flaxseed, dry edible peas, lentils, soybeans, corn, and cattle — the USDA Rural Energy for America Program (REAP) is the single most powerful solar incentive available. It can transform a 12–15 year payback into a 3–5 year payback even at North Dakota's very low electricity rates.

What REAP Provides

• Grants up to 50% of total eligible project costs
• Loan guarantees up to 75% of project costs (can be stacked with the grant, up to 75% combined)
• Eligible applicants: Agricultural producers (at least 50% of gross income from agriculture) and rural small businesses in communities under 50,000 population
• Eligible projects: Solar photovoltaic, wind, geothermal, biomass, and other renewable energy systems; also energy efficiency improvements

North Dakota is one of the top REAP-recipient states in the country precisely because of its concentration of agricultural producers with significant electricity needs — irrigation pumps, grain dryers, cold storage, livestock operations — and a rural small-business economy that broadly qualifies.

REAP Farm Solar Example

A North Dakota row-crop farmer near Jamestown (Stutsman County) runs a 1,500-acre operation with irrigation and grain drying that results in annual electricity bills of $8,000–$12,000/year. They install a 15 kW solar system:

• Gross cost: $43,500 (at approximately $2.90/watt installed)
• REAP grant (50%): −$21,750
• Remaining cost after grant: $21,750
• Federal ITC (30% of $21,750): −$6,525
• Net cost: $15,225
• Annual savings at $0.12/kWh: ~$7,860 (using 5.0 peak sun hours, Jamestown area, 15 kW × 5.0 × 365 × 85% = ~23,400 kWh/year)
• Simple payback: Under 2 years

Even with more conservative assumptions — partial self-consumption, lower REAP award, or smaller system — farm paybacks with REAP routinely come in at 3–5 years, making solar one of the strongest capital investments available to North Dakota agricultural operations.

REAP applications are submitted through the USDA Rural Development state office. Applications are accepted on a rolling basis with quarterly funding cycles; early submission in each cycle improves funding probability. See the solar grants guide for REAP application details and tips on strengthening your application.

Important: REAP grants are taxable income to the recipient. However, the remaining portion of the system after the grant still qualifies for the full 30% ITC, and the grant amount itself does not reduce the ITC basis. Work with a tax professional familiar with agricultural operations to structure your REAP and ITC claims optimally.

Full Incentive Stacking Examples for North Dakota Homeowners

Example 1: Bismarck Homeowner — MDU Territory, Standard 30% ITC

• System: 9 kW, Burleigh County homeowner, MDU territory
• Gross cost: $26,100 (includes 5% ND sales tax of ~$1,245)
• Federal ITC (30%): −$7,830
• Property tax exemption (5 years at 1.0% on $23,000 assessed value): ~$1,150 saved
• Net effective cost: ~$17,120
• Annual production: ~12,744 kWh (4.8 peak sun hours × 9 kW × 365 days × 80.7% system efficiency)
• Annual savings: ~$1,529 (at $0.12/kWh MDU rate for self-consumed production)
• Simple payback on ITC-adjusted cost: ~12–13 years
• Including property tax exemption value: ~11.5–12 years

Bismarck's 4.8 peak sun hours/day is a solid resource for a northern-latitude state — comparable to Minneapolis and better than most of the Great Lakes region.

Example 2: Fargo Homeowner — Xcel/NSP Territory, Standard 30% ITC

• System: 8 kW, Cass County homeowner, Xcel Energy (NSP) territory
• Gross cost: $23,200 (includes 5% ND sales tax)
• Federal ITC (30%): −$6,960
• Property tax exemption (5 years at 1.0% on $21,000 assessed value): ~$1,050 saved
• Net effective cost: ~$15,190
• Annual production: ~10,640 kWh (4.6 peak sun hours × 8 kW × 365 × 79%)
• Annual savings: ~$1,170 (at $0.11/kWh Xcel NSP rate)
• Simple payback: ~13 years
• Including property tax exemption: ~12–12.5 years

Fargo sits slightly lower at 4.6 peak sun hours/day due to its position near the Minnesota border and cloud patterns off the Red River Valley. The NSP rate is also slightly lower than MDU, moderately extending payback compared to Bismarck.

Example 3: Oliver County — Energy Community 40% ITC (Best Case in ND)

• System: 10 kW, Oliver County homeowner (near Stanton/Coal Creek Station), Energy Community eligible
• Gross cost: $29,000
• Federal ITC (40%): −$11,600
• Property tax exemption (5 years at 1.0% on $26,000 assessed value): ~$1,300 saved
• Net effective cost: ~$16,100
• Annual production: ~13,870 kWh (4.8 peak sun hours × 10 kW × 365 × 79%)
• Annual savings: ~$1,665 (at $0.12/kWh, assuming MDU or co-op territory)
• Simple payback: ~9.7 years
• Including property tax exemption: ~9 years

This is the standout scenario in North Dakota — a buyer who qualifies for the Energy Community 40% ITC can achieve near-10-year payback even with the state's characteristically low electricity rates. Oliver, McLean, and Mercer county residents should prioritize verifying their Energy Community status before contracting for solar.

Example 4: Farm REAP Installation — The Transformational Case

• System: 15 kW farm solar system, rural Stutsman County (Jamestown area)
• Gross cost: $43,500
• USDA REAP grant (50%): −$21,750
• Federal ITC (30% on remaining $21,750): −$6,525
• Net cost: $15,225
• Annual electricity savings: ~$2,800–$3,500 (farm electricity use 23,000+ kWh/year)
• Simple payback: 4–5 years (conservative estimate)
• Including property tax exemption: Under 4 years

For eligible agricultural producers, this is one of the strongest solar investment cases in the northern United States — a better financial outcome than most installations in solar-friendly states like California or Arizona, achieved through stacking grants and federal incentives rather than high electricity rates.

North Dakota Solar by City: Sun Resource Summary

North Dakota's plains geography provides a surprisingly good solar resource for its northern latitude. The lack of mountains and relative scarcity of coastal fog means clear skies predominate across much of the state.

City	Peak Sun Hours/Day	Typical 9 kW Annual Output	Annual Savings at $0.12/kWh
Bismarck	4.8	~12,744 kWh	~$1,529
Dickinson	4.9	~13,010 kWh	~$1,561
Minot	4.7	~12,478 kWh	~$1,497
Jamestown	5.0	~13,275 kWh	~$1,593
Fargo	4.6	~12,213 kWh	~$1,466
Grand Forks	4.5	~11,948 kWh	~$1,434
Williston	4.8	~12,744 kWh	~$1,529

Estimates based on 9 kW system, 79% system efficiency derate, 365-day year.

Dickinson and the southwestern corner of North Dakota consistently offer the best solar resource, benefiting from lower humidity and more consistent clear weather. Fargo and Grand Forks have slightly lower sun hours due to Red River Valley weather patterns.

North Dakota vs. Neighboring States

How does North Dakota stack up for solar compared to its neighbors?

State	Net Metering	Sales Tax	Property Tax Exemption	State Credit	Avg. Rate	Typical Payback
North Dakota	Retail (Xcel/MDU IOUs only)	5% (no solar exempt)	5-year 100%	None (expired)	$0.10–$0.13/kWh	11–15 years
Minnesota	Retail + Solar*Rewards	Exempt	Limited	Program rebates	$0.12–$0.15/kWh	9–12 years
Montana	Retail (NWE)	None	10-year 100%	$500 lifetime	$0.09–$0.11/kWh	11–16 years
South Dakota	Retail (varies by utility)	4.5% (no solar exempt)	Limited	None	$0.10–$0.12/kWh	12–16 years
Wyoming	Retail (RMP IOU)	4% (limited exempt)	Limited	None	$0.09–$0.11/kWh	12–16 years

Minnesota is the strongest market in the region — higher base electricity rates, sales tax exemption on solar, and Xcel Energy's Solar*Rewards program all contribute to better economics for Minnesota buyers. See the Minnesota solar guide for a detailed comparison.

Montana offers a stronger property tax exemption (10 years vs. 5 years) and the critical advantage of no sales tax, but very similar electricity rates. See the Montana solar guide for the full comparison.

North Dakota holds its own against South Dakota and Wyoming, both of which lack the NDPSC net metering mandate and have similarly low electricity rates. ND's Energy Community ITC (for qualifying coal-county buyers) and REAP opportunity (for agricultural producers) are genuine competitive advantages over its southern and western neighbors.

Cold-Weather Solar Performance in North Dakota

North Dakota winters are severe — Bismarck averages temperatures below 0°F on multiple nights each winter, and the Williston and Minot areas regularly see sustained subzero periods. This is not a problem for solar panel performance:

Cold-weather performance advantage: Modern crystalline silicon solar panels perform better in cold temperatures than in summer heat. Panels have a negative temperature coefficient (roughly −0.35% to −0.45% per °C above the rated temperature), meaning that on a cold, clear February day in Bismarck, panel output can actually exceed the panel's rated capacity.

Snow is the primary concern: Accumulated snow on panels can reduce production to zero during accumulation periods. North Dakota's wind helps — windswept rural installations often self-clear faster than suburban rooftops. A steep south-facing roof pitch (35–45°) combined with the weight and low friction of modern panel surfaces helps shed snow. Panel-mounted heating systems exist but are rarely cost-effective for residential scale.

Winter production reality: Expect December and January to be the lowest production months, contributing perhaps 40–50% of summer monthly production on a per-day basis. North Dakota's summer months (June, July, August) are the production powerhouses — long days, intense sun, moderate temperatures, and low humidity. Annual production figures account for this seasonality and represent a realistic average.

Is Solar Worth It in North Dakota?

Solar in North Dakota makes the strongest financial case for:

1. Energy Community county residents (Oliver, McLean, Mercer, Billings) — the 40% ITC cuts payback to approximately 9–11 years, competitive with many Midwest states
2. Agricultural producers — REAP grant eligibility transforms solar economics completely; 3–5 year payback is achievable and common
3. Rural small businesses in communities under 50,000 — also REAP-eligible, and often have higher electricity consumption than residential customers
4. High-consumption households — a family using 1,500+ kWh/month sees meaningfully better economics than one using 800 kWh/month
5. MDU customers in Bismarck and Minot — MDU's modestly higher rates ($0.11–$0.13/kWh) make solar slightly more attractive than in Fargo/Xcel territory

The financial case is harder for:

• Standard residential buyers in Fargo or Grand Forks (Xcel/NSP rates, lower sun hours, 12–15 year payback)
• Rural co-op customers without confirmed net metering policies
• Homeowners planning to sell within 10 years (though solar does add home value)
• Those without sufficient federal tax liability to absorb the ITC

The honest assessment: North Dakota is a moderate solar market for residential buyers, but a strong to exceptional market for agricultural producers and Energy Community county buyers. Anyone in either of those categories should treat solar as a serious near-term financial investment, not just an environmental choice.

Installer Market and Getting Quotes

The North Dakota solar installer market is smaller than neighboring Minnesota or Colorado but has grown substantially since 2020. Key installer hubs include Bismarck, Fargo, Minot, and Grand Forks. Rural buyers in western North Dakota may work with Bismarck-based installers willing to travel to Dickinson, Williston, or Watford City.

When getting quotes:

• Request quotes from at least 3 installers — prices vary meaningfully
• Ask each installer about their experience with REAP applications if you're a farm operator
• Verify that the installer is familiar with MDU or Xcel/NSP interconnection procedures specific to North Dakota
• Ask whether they handle the property tax exemption application (NDCC § 57-02-09.1) paperwork or whether you'll need to file it yourself

See the solar panel installation cost guide for national benchmarks and what to expect per watt installed in the upper Midwest market.

Action Steps for North Dakota Solar Buyers

1. Determine your utility: Xcel Energy (NSP), Montana-Dakota Utilities, or a rural cooperative. If a co-op, call and confirm net metering policy before proceeding.

2. Check Energy Community eligibility: Visit the IRS Energy Community lookup tool and enter your address. If you're in Oliver, McLean, Mercer, or Billings County, you may qualify for the 40% ITC — this changes your financial model significantly.

3. Assess REAP eligibility: If you're an agricultural producer or rural small business, contact USDA Rural Development's North Dakota state office in Bismarck to discuss REAP eligibility and application timing.

4. Use the Solar System Designer to estimate system size based on your North Dakota electricity usage and location.

5. Model your payback: Use the payback period calculator with your actual electricity rate and estimated production for your city.

6. Get 3–4 quotes from local and regional North Dakota installers. Prices and service quality vary.

7. File property tax exemption: After installation, contact your county assessor's office to file the NDCC § 57-02-09.1 exemption application. Don't forget this step — it's not automatic.

8. Consider battery storage: North Dakota's severe winters and rural geography make solar+battery storage attractive for resilience. See the home battery storage guide for costs and sizing.

Frequently Asked Questions

Does North Dakota have a solar tax credit? Not currently. North Dakota had a state income tax credit for solar in prior years, but it expired and has not been renewed as of 2026. No state credit is available for new installations. Focus your financial modeling on the federal ITC (30% or 40% in Energy Community counties) and USDA REAP for eligible agricultural buyers.

Does North Dakota charge sales tax on solar panels? Yes. North Dakota's 5% state sales tax applies to solar equipment and installation. There is no solar-specific exemption. This adds approximately $1,000–$1,500 to a typical residential system cost compared to sales-tax-exempt states like Montana or Minnesota.

How does net metering work with Xcel Energy NSP and MDU in North Dakota? Both utilities offer retail-rate net metering under the NDPSC mandate. Monthly surplus production carries forward as a credit at the retail rate. At the annual true-up (April and October), any remaining accumulated credits are settled at the much lower avoided cost rate (~$0.03–$0.05/kWh). This makes it important to size your system to match your annual consumption rather than oversize for maximum production.

Are rural electric cooperatives in North Dakota required to offer net metering? No. The NDPSC net metering mandate covers only investor-owned utilities (Xcel/NSP and MDU). Rural electric cooperatives served at wholesale by Basin Electric Power Cooperative or Minnkota Power are not subject to the mandate. Individual co-ops may offer voluntary net metering programs; verify with your specific co-op before proceeding with a solar installation.

What is the NDCC § 57-02-09.1 property tax exemption? This is North Dakota's 5-year property tax exemption for solar energy equipment. Under this statute, the value added to your property by a qualifying solar installation is exempt from property taxation for five years from the installation date. The exemption is not automatic — you must file an application with your county assessor's office. The exemption typically saves $900–$1,500 over five years depending on system size and local mill levy.

What counties qualify for the Energy Community 40% ITC in North Dakota? Oliver County (Coal Creek Station area), McLean County, Mercer County (Antelope Valley Station area), and Billings County are the primary qualifying counties based on coal power plant employment and fossil fuel industry history. Portions of Adams County and other western ND counties may include qualifying census tracts. Always verify your specific address using the official IRS Energy Community lookup tool, as eligibility is determined at the census tract level, not county-wide in all cases.

Is USDA REAP available for North Dakota farms? Yes, and it's one of the strongest REAP opportunities in the country. North Dakota's concentration of agricultural producers — the state is a top-five producer of numerous crops and a major cattle state — means that a large portion of the state's rural population is REAP-eligible. A farm installing solar with a 50% REAP grant and the 30% ITC on the remainder can achieve effective net costs of 35% of the original system price, with payback periods of 3–5 years even at North Dakota's low electricity rates.

Summary: North Dakota Solar in 2026

North Dakota solar buyers have a functional but not generous incentive stack: a 5-year property tax exemption, retail-rate net metering from Xcel/NSP and MDU, and the federal 30% ITC. The absence of a state income tax credit and the 5% sales tax with no exemption are real gaps that add cost and extend payback compared to neighboring Minnesota.

The honest payback story for standard residential buyers is 11–15 years — longer than the national average but not unusual for a low-rate state. The two cases where North Dakota solar makes an exceptional financial argument are: Energy Community counties (Oliver, McLean, Mercer, Billings) where the 40% ITC cuts payback to approximately 9–11 years, and agricultural producers where USDA REAP grants of up to 50% combined with the federal ITC can drive payback periods as low as 3–5 years.

If you're in either of those categories, solar in North Dakota is one of the better capital investments available to you in 2026. If you're a standard residential buyer in Fargo or Grand Forks with a modest electricity bill, the math is harder — but rising electricity rates and the 5-year property tax exemption still make solar a defensible long-term investment for homeowners planning to stay in their home for 15+ years.

Use the Solar System Designer to build a system specification for your North Dakota home, and the payback period calculator to model your specific scenario. For farm buyers, contact USDA Rural Development in Bismarck immediately — REAP funding is competitive and submitting early in each quarterly cycle improves your odds.
