It has nothing to do with tax. It has to do with the power company NOT allowing you to sell back your excess power from Solar to them. It is about charging more to other customers because you have solar. That is the problem with these Amendments. If you don't have someone to explain them to you, then you don't know what they will mean to you.

Right now, the gov gives you a tax break for using Solar
right now, you can sell your extra power from solar back to the power company
Right now, the power company can not penalize those that do not have solar by making them pay more for their power.
