That makes very little sense. You're making an apples to oranges comparison here. It would be absolutely impossible to pull that off. It's literally the premium roof + solar and you want it to be the same price as premium roof (thus, you want the solar hardware to cost nothing.
Only one of these generates electricity, thus saving you money and that must be included in the cost calculation in order to determine the actual cost.
