How to read this map
Law in force means a state statute specifically exempts small plug-in systems (usually up to 1,200 W AC, certified by a nationally recognized lab) from utility interconnection applications and permits. Signed, not yet in effect means the same, but the start date is in the future. No specific law does not mean plug-in solar is banned: it means the general interconnection rules of your utility apply, and most utilities require an application before any device exports power to the grid.
