The Texas property tax code allows an exemption of the amount of 100% of the appraised property value increase arising from the installation or construction of a solar or wind-powered energy device that is primarily for the production and distribution of thermal, mechanical, or electrical energy for on-site use and devices used to store that energy.

Under H.B. 2500 (2013), solar energy devices installed or constructed on or after January 1, 2014, used for a commercial purpose are subject to the cost method of appraisal, and the depreciated value must be calculated using a useful life of 10 years

Note: This exemption may not be allowed for the tax years beginning after July 1, 2029.

Oregon law states that any change in real market value to property due to the installation of a qualifying renewable energy system is exempt from assessment of the property’s value for property tax purposes. Qualifying renewables include solar, geothermal, wind, water, fuel cell or methane gas systems used to heat, cool or generate electricity. This exemption is intended for end users and only applies to systems that are net metered or primarily intended to offset on-site electricity use.  Systems installed on real property that

The State Agency Loan Program (SALP) was established in 1991 using funds from the Energy Overcharge Restitution Fund. Through this revolving loan program, the Maryland Energy Administration (MEA) provides loans to state agencies for cost-effective energy efficiency improvements in state facilities. Typical loan amounts range from $50,000 to $250,000. State agencies pay zero interest with a one percent administration fee. Their repayments are made from the agency's fuel and utility budget, based on the avoided energy costs of the project. Repayments replenish the fund so that it can continue to make additional loans each year. During 2011 alone the MEA reports

Montana's property tax exemption for recognized non-fossil forms of energy generation and low emission wood or biomass combustion devices may be claimed for 10 years after installation of the property.

In 1975, the City of Santa Clara established the nation's first municipal solar utility. Under the Solar Water Heating Program, the Santa Clara Water & Sewer Utilities Department supplies, installs and maintains solar water heating systems for residents and businesses. In addition, the city has also installed solar energy equipment for a number of its own facilities.

Solar equipment is available from the city for heating swimming pools, process water and domestic hot water. The hardware (solar collectors, controls and storage tanks) is owned and maintained by the city under a rental agreement. The renter pays an initial installation fee

Arizona provides a sales tax exemption* for the retail sale of solar energy devices and for the installation of solar energy devices by contractors.

The sales tax exemption does not apply to batteries, controls, etc., that are not part of the system. (Note that H.B. 2429, enacted in June 2006, eliminated the $5,000 limit per device.)

S.B. 1229 of 2012 extended this exemption to net metering transactions
