Solar power in North Dakota has been a little-used resource. The state ranks last on installed solar power in the United States, with .47 MW of installed capacity. [1] [2] Solar on rooftops can provide 24.6% of all electricity used in North Dakota from 3,300 MW of solar panels. [3] The most cost effective application for solar panels is for pumping water at remote wells where solar panels can be installed for $800 vs. running power lines for $15,000/mile. [4]
Traditionally a coal and wind state, the cost reduction of solar has enabled North Dakota to include solar power plants in its grid. A 200 MW solar station costing $250 million and covering 1,600 acres was approved in 2019, to operate in Cass County by 2020. [5]
The first solar farm in North Dakota, the 300 kilowatt Cannon Ball Community Solar Farm opened in February 2019, and represented "half the total solar energy being generated across the state," according to its press release. [6] [7] The solar farm is located on the Standing Rock Reservation, which saw increased interest in renewable energy as a result of the Dakota Access Pipeline protests. [6] [7]
Net metering is available monthly to all consumers generating up to 100 kW, one of the worst policies in the country, as it is reconciled monthly at the avoided cost rate, meaning that only a portion is rolled over, although some utilities add a REC adder, [8] giving the state a D. [9] The primary reason to use net metering is to roll over summer generation to winter usage, which requires continuous roll over of excess generation. [10] Technically North Dakota's net metering policy is an FIT program, not a net metering policy, because meters are only read once a month, and is an FIT program that pays one of the lowest rates in the world, as it 1) only pays for excess generation, and 2) pays a lower, rather than a higher, rate. By comparison, Ontario's 2010 FIT program paid 80.2¢ Canadian/kWh for rooftop mounted solar panels. [11]
Both North Dakota State University and the University of North Dakota built solar race cars. A solar car uses less power than a toaster, but can travel continuously at 55 mph using energy stored in batteries, charged only from the car's solar panels. In 2009 a solar car of this type visited Fargo while setting the record for the farthest distance traveled by a solar car. Today's solar race cars are typically street legal, although they are so different looking that in Alaska one was mistaken for a UFO. [12]

Solar power in Colorado has grown rapidly, partly because of one of the most favorable net metering laws in the country, with no limit on the number of users. The state was the first in the nation to establish a Renewable Portfolio Standard for its electric utilities.
Solar power in Nebraska is used for only a very small percentage of the state's electricity, although it is rapidly becoming competitive with grid electricity, due to the decrease in cost and the 30% tax credit, which can be used to install systems of any size. In 2024, the state ranked 44th among the 50 U.S. states with 203 MW of installed capacity.
As of the first quarter of 2023, Washington State has 604 MW of solar power electricity generation. This is an increase from about 300 MW in 2021 and 27 MW in 2013.
Solar power in Ohio has been increasing, as the cost of photovoltaics has decreased. Ohio installed 10 MW of solar in 2015. Ohio adopted a net metering rule which allows any customer generating up to 25 kW to use net metering, with the kilowatt hour surplus rolled over each month, and paid by the utility once a year at the generation rate upon request. For hospitals there is no limit on size, but two meters are required, one for generation, the other for utility supplied power.
Solar power in Indiana has been growing in recent years due to new technological improvements and a variety of regulatory actions and financial incentives, particularly a 30% federal tax credit for any size project.
Solar power in Kansas has been growing in recent years due to new technological improvements and a variety of regulatory actions and financial incentives.
Solar power in West Virginia on rooftops can provide 23% of all electricity used in West Virginia from 6,300 MW of solar panels, but West Virginia will be the last state in the United States to reach grid parity - the point where solar panels are cheaper than grid electricity - without incentives, due to the low cost of electricity - about $0.062/kWh. The point where grid parity is reached is a product of the average insolation and the average cost of electricity. At $0.062/kWh and 4.3 sun-hours/day, solar panels would need to come down to ~$1,850/kW installed to achieve grid parity. The first state in the US to achieve grid parity was Hawaii. Solar power's favorable carbon footprint compared to fossil fuels is a major motivation for expanding renewable energy in the state, especially when compared to coal to generate electrical power.
Solar power in Iowa is limited but growing, with 137 megawatts (MW) installed by the end of 2019 and 27 MW installed during that year, ranking the state 40th among U.S. states. Iowa also generated 0.23% of the state's total electricity production in 2019 from solar energy; an amount sufficient to power over 17,000 Iowa homes. The state's early position as a major wind-power provider may have limited early large-scale solar investment.
Solar power in South Dakota has high potential but little practical application. The state ranked 50th among U.S. states in installed solar polar in 2015 with no utility-scale or large commercial systems. Photovoltaic panels on rooftops can provide 38.7% of all electricity used in South Dakota using 3,800 MW of solar panels. The state is ranked 14th in the country in solar power potential, and 4th in wind potential.
Mississippi has substantial potential for solar power, though it remains an underutilized generation method. The rate of installations has increased in recent years, reaching 438 MW of installed capacity in early 2023, ranking 36th among the states. Rooftop photovoltaics could provide 31.2% of all electricity used in Mississippi from 11,700 MW if solar panels were installed on every available roof.
Solar power in Oklahoma can provide 44.1% of all electricity used in Oklahoma from 19,300 MW of rooftop solar panels. This scenario is extremely unlikely though because the cost of electricity in Oklahoma is among the lowest in the nation.
Solar power in Minnesota expanded significantly in the early 2010s as a result of the cost decrease of photovoltaics and favorable policies. By 2016, it began to grow quickly.
Solar power in Missouri has been a growing industry since the early 2010s. Solar power is capable of generating 42.7% of the electricity used in Missouri from rooftop solar panels totaling 28,300 MW.
Solar power in Idaho comprised 550 MW in 2019. A 2016 report by the National Renewable Energy Laboratory estimated that rooftops alone have the potential to host 4,700 MW of solar panels, and thus provide 26.4% of all electricity used in Idaho. A large increase in the state's solar generating capacity began starting year 2015 when 461 MW of solar power was contracted to be built in Idaho.
Solar power in Montana on rooftops could provide 28% of all electricity used in Montana from 3,200 MW of solar panels.
Solar power in New Hampshire provides a small percentage of the state's electricity. State renewable requirements and declining prices have led to some installations. Photovoltaics on rooftops can provide 53.4% of all electricity used in New Hampshire, from 5,300 MW of solar panels, and 72% of the electricity used in Concord, New Hampshire. A 2016 estimate suggests that a typical 5 kW system costing $25,000 before credits and utility savings will pay for itself in 9 years, and generate a profit of $34,196 over the rest of its 25-year life. A loan or lease provides a net savings each year, including the first year. New Hampshire has a rebate program which pays $0.75/W for residential systems up to 5 kW, for up to 50% of the system cost, up to $3,750. However, New Hampshire's solar installation lagged behind nearby states such as Vermont and New York, which in 2013 had 10 times and 25 times more solar, respectively.
Solar power in Vermont provides almost 11% of the state's in-state electricity production as of 2018. A 2009 study indicated that distributed solar on rooftops can provide 18% of all electricity used in Vermont. A 2012 estimate suggests that a typical 5 kW system costing $25,000 before credits and utility savings will pay for itself in 10 years, and generate a profit of $34,956 over the rest of its 25-year life.
Solar power in Wisconsin In 2026, Wisconsin rooftops can accommodate approximately 37 GWs of solar capacity and produce 44,183 GWh of electricity, nearly 70% of the statewide generation in 2019. Net metering is available for systems up to at least 20 kW, and excess generation is credited at retail rate to customers next bill. Some utilities allow net metering up to 100 kW. For Xcel customers, kilowatt credits are rolled over monthly and are reconciled annually at avoided cost. Best practices recommend no limits, either individually or aggregate, and perpetual roll over of kilowatt credits.
Solar power in Delaware is small industry. Delaware had 150 MW of total installed capacity in 2020. The largest solar farms in the state included the 10 MW Dover Sun Park and the 12 MW Milford Solar Farm.
Solar power in Tennessee is capable of producing much of the state's electricity; however, the industry remains in early stages in the state. With 129 MW of solar power in 2015, Tennessee ranked 20th among states for installed solar capacity.
