Solar Energy Systems Tax Credit (Corporate)

Note: This tax credit is only available for installations that begin construction before the beginning of calendar year 2022. Eligible installations can still receive credits in 2022, but no new facilities can become eligible.

Iowa offers a corporate tax credit for solar energy systems. Specifically, the law allows individuals and corporations to claim a state tax credit worth 50% of the Federal Investment Tax Credit. Each taxpayer may claim up to $5,000 for residential systems and $20,000 for commercial systems under this program, and any excess credits may be carried over for up to 10 years.

Permits and Variances for Solar Panels, Calculation of Impervious Cover

In May 2012, Maryland enacted legislation stating that any calculation of "impervious surface" required by state or local authorities as part of a permit or variance relating to zoning, construction, or stormwater may only include the foundation or base supporting the solar panel. The law generally applies statewide, including charter counties and Baltimore City. It does not however apply in a defined "critical area", including the Chesapeake Bay Critical Area and the Coastal Bays Critical Area. The term "solar panel" is not specifically defined, but presumably would include both solar photovoltaic (PV) and solar thermal panels.

Energy Project and Equipment Financing

The Virginia Resources Authority (VRA) was created in 1984 and provides financial assistance to local governments in Virginia for a variety of projects, including energy and energy conservation projects. In March 2011, H.B. 2389 added "renewable energy" to the list of eligible projects (though it may have already been technically eligible under the "energy" category). VRA offers a couple financing options, including the Virginia Pooled Financing Program and Revolving Loan Funds. Interested entities can use the contact form available on the VRA web site in order to discuss financing options with VRA staff.

Renewable Energy Pilot Program

In June 2010, the Louisiana Public Service Commission (LPSC) unanimously approved a Renewable Energy Pilot Program to determine whether a renewable portfolio standard (RPS) is suitable for Louisiana. The program was concluded in August of 2013 with the determination that, while utilities, staff, and regulators learned a great deal, a mandatory RPS was not needed in Louisianna. Three major reasons given not to pursue an RPS were 1) that renewable energy generation is more expensive than conventional energy generation, 2) that rising natural gas prices have put renewables at a cost disadvantage, and 3) that federal interest in mandatory RPS

Sales and Use Taxes for Items Used in Renewable Energy Industries

Connecticut enacted legislation in May 2010 (H.B. 5435) that established a sales and use tax exemption for equipment, machinery and fuels used to manufacture solar thermal (active or passive) systems, solar electric systems, wind-power electric systems, or geothermal resource systems.

Commercial & Industrial Solar Rebate Program

The New Hampshire Public Utilities Commission initiated a new solar rebate program for non-residential applicants in November 2010. Funded by alternative compliance payments under the state's renewable portfolio standard (RPS), this program supports solar photovoltaic (PV) and solar-thermal installations. In 2021, the New Hampshire DOE was given the administration and implementation authority over RPS policy and related renewable energy fund (per H.B. 2).

Installations must be located in the state of New Hampshire, and the facility must be served by an investor-owned utility or rural electric utility that is required to comply with the state's RPS (municipal utilities are

Local Option - Energy Efficiency & Clean Energy Districts

Note: In 2010, the Federal Housing Finance Agency (FHFA), which has authority over mortgage underwriters Fannie Mae and Freddie Mac, directed these enterprises against purchasing mortgages of homes with a PACE lien due to its senior status above a mortgage. Most residential PACE activity subsided following this directive; however, some residential PACE programs are now operating with loan loss reserve funds, appropriate disclosures, or other protections meant to address FHFA's concerns. Commercial PACE programs were not directly affected by FHFA’s actions, as Fannie Mae and Freddie Mac do not underwrite commercial mortgages.
