Solar power has been growing in the U.S. state of Oregon in recent years due to new technological improvements and a variety of regulatory actions and financial incentives enacted by the state government.
The Government of Oregon has taken a variety of actions to encourage solar energy use and manufacturing within the state. A 2017 law states that homeowners associations cannot ban solar panels. [1]
The state has a net metering program that allows for large installations of up to 2 MW of on-site electrical generation. [2] A report released in 2009 by the Network for New Energy Choices and Vote Solar gave the state's net metering system an "A" grade, a rating only 9 other states received. [3]
The state adopted a Renewable Portfolio Standard (RPS) in 2007 which requires that 25% of Oregon's electricity come from renewable resources by 2025. [4] The RPS was revised in 2009 to include a separate 20 MW solar photovoltaic requirement by 2020. [5]
Passed in the 2007 legislative session, House Bill 2620, requires that public entities such as state and local governments spend 1.5% of the construction budget for new or renovated buildings on on-site solar technologies. [4] [6]
Solar Within Reach is a program through the Energy Trust of Oregon that provides incentives for income-qualified families. Adding a solar power system to your home can greatly reduce your energy bills, and this program is designed to help offset the costs of installing such a system, so you can reap the benefits without a big startup cost. [7]
In 2019, HB 2618 was passed, which created a new ODOE solar rebate program through the Oregon Department of Energy (ODOE). This rebate program allows residential solar energy customers as well as low-income service providers in Oregon to receive rebates for solar energy systems, whether they are stand-alone systems or paired with a solar energy storage system. [8]
The Residential Energy Tax Credit (RETC) program aims to encourage residents to invest in energy efficient appliances or residential-scale power producing systems such as roof-mounted solar or small wind setups by offering a tax credit that covers a certain percentage of the cost of eligible equipment. [9]
The Business Energy Tax Credit (BETC) program aims to encourage private businesses to invest in renewable energy in Oregon by offering a tax credit that covers up to 50% of eligible renewable projects such as power stations or manufacturing factories with a maximum limit of $20 million per project. [4]
The State Energy Loan Program aims to encourage investment in energy efficiency and renewable energy production by offering long-term, fixed-rate loans to all types of organizations and individuals with a maximum cap at $20 million per loan. [10] From the time it was first authorized by voters in 1980, the program has made over 700 loans worth a total of $335 million. [11]
The Oregon Legislative Assembly established a feed-in tariff for solar power modeled on feed-in tariffs in Germany, [12] allowing owners of solar installations to be paid for the electricity they produce. [13] On May 28, 2010, the Oregon Public Utility Commission approved the trial feed-in tariff rules. [14] Under the approved rules, residents and businesses who install solar systems can enter a 15-year contract with investor-owned utilities in the state where they will receive guaranteed monthly payments over the life of the contract with rates ranging from $0.55 to $0.65 per kWh. [15] Funding will come from an estimated one half of 1% increase in electricity rates. [15] The trial program ends after four years and the entire project's size is limited to a maximum 25 MW. [14] Program applications are accepted biannually on April 1 and October 1. The final year of the pilot program is 2013. [16]
Many solar manufacturing companies have chosen to operate in Oregon because of its cheap hydroelectric power which is important for manufacturing and because of its close proximity to California's large market. [17] The inexpensive hydroelectric power has also contributed to the high-tech manufacturing companies located in the state's Silicon Forest as well as several data centers such as Google's Project 02. [18]
Oregon was one of the only three states (along with Michigan and Ohio) to manufacture more than 100 MW of solar panels during 2009. [19] SolarWorld's plant in Hillsboro, Oregon is the largest solar cell manufacturing factory in North America and is planned to produce 500 MW of panels annually by 2012. [20] [21]
Solar companies with operations in Oregon include, Sunbridge Solar, Precision Solar & Heating, Energy Solutions, Avila Solar Drafting LLC, Solar Plan Sets LLC, Power Northwest, Tesla Solar, Grape Solar, and more. [22]
In 2002 Oregon became the first state to install solar panels on its state capitol building. [23] The solar panels were installed on the Oregon State Capitol building, although they are not visible from the street.
In 2008, the Oregon Department of Transportation announced the completion of a 104 kW solar panel project along the interchange of Interstate 5 and I-205 near Tualatin, Oregon. [24] The project is the first solar highway in Oregon and the first in the United States.
In January 2012, the Oregon Department of Transportation announced the completion of its second solar highway project with a 1.75 megawatt capacity at its Baldock Safety Rest Area south of Wilsonville. [25]
A 165 kW expansion to the first project is under study, as is a potential third solar highway project with a capacity of 3 megawatts at ODOT's maintenance storage facility in West Linn. [26] [27] The 3 megawatt project in West Linn, Oregon would be the largest solar highway in the world, slightly passing the 2.8 megawatt record holder in Germany. [28]
Portland, Oregon is one of the 25 cities in the United States Department of Energy's Solar America Cities program. The program's goal is to "rapidly increase the use and integration of solar energy in communities across the country." [29]
Solar energy is the state's most abundant energy resource and estimates have placed the state's potential electricity production from solar power at 68,000,000 MWhs annually, an amount larger than the state's total electricity consumption of 46,457,000 MWh in 2005. [30] [31]

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.
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 Louisiana is ranked 34th for installed solar PV capacity as of 2017 by the Solar Energy Industry Association. The state's "solar friendliness" according to Solar Power Rocks has fallen to 50th place for 2018 as the state credit program ends and full 1:1 retail net metering is being phased out. Taxpayers still benefit from federal incentive programs such as the 30 percent tax credit, which applies to business and residential solar photovoltaic and thermal energy systems of any size.
Solar power in Wyoming has the potential to generate 72 million MWh/yr. Wyoming used 12 million MWh in 1999. Net metering is available to all consumers generating up to 25 kW. The state has an installed capacity of 146 MW as of 2022.
Solar power in Rhode Island has become economical due to new technological improvements and a variety of regulatory actions and financial incentives, particularly a 30% federal tax credit, available through 2016, for any size project. A typical residential installation could pay for itself in utility bill savings in 14 years, and generate a profit for the remainder of its 25 year life. Larger systems, from 10 kW to 5 MW, receive a feed-in tariff of up to 33.45¢/kWh.
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 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.
Solar power in Maine on rooftops, utilizing 6,300 megawatts (MW) of solar panels, can provide 60% of the electricity used in Maine according to a 2016 U.S. Department of Energy study. Maine and Vermont are tied for the second highest rooftop solar potential in the country, only behind the state of California. A 2020 estimate suggests that a typical 5.6 kilowatt (kW) residential system will pay for itself in 6-7 years and generate a profit of $45,000 over the rest of its 25-year life from the tax credits and utility savings.
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 Arkansas on rooftops can provide 33.3% of all electricity used in Arkansas from 12,200 MW of solar panels.
Solar power in Alabama on rooftops could theoretically provide 29.8% of all electricity used in Alabama, with 20,400 MW of solar panels potentially installed on rooftops.
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 Maryland is supported by the state's legislation regarding the Renewable Portfolio Standard and Solar Renewable Energy Credit (SREC) program. The target for renewable energy as of 2017 is 20% by 2020, including 2% from solar power.
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 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.
