Arkansas has very limited programs available to help offset the conversion to solar power. Many additional programs, however, are available through the federal government.
Arkansas does have a mandatory program for Green Building Standards for State Facilities, requiring them to be LEED certified.
Additionally, there is a program for interconnection and net metering.
Further information, including information about all of the federal programs, can be found by visiting the DSIRE:Database of State Incentives for Renewables & Efficiency.
