States With Plug-In Laws
10 states have passed laws that let a certified kit under the cap plug in with no utility agreement, and 4 of them have a later start date. Because the caps are worded differently, we take whichever is greater, the panels' total or the inverter's output, which is 1,200 W here, and compare it with the cap. Next, we check the listing the law requires.
