There are some great NC solar tax credits that make the installations of such systems more affordable.  They can save an individual up to 35% (subject to maximum spend limitations) on solar and other renewable energy projects.   The NC Solar Center assists both professionals and end-user clients navigate issues, training, etc.  The most recent version of the NC budget may remove their funding, which is a shame.  These are the types of industries and jobs that should be encouraged and anything done to make the process more difficult should only be viewed as a disservice to the general public.
