What I've seen is its like a grid tie thats only engaged when your a/c is on. You can use it with or without panels, or add panels in the future. Even a small 2 ton a/c uses 1k-2000 watts so you'll need a lot of panels to cancel out a/c usage. In central TX my a/c is shut off from 8am until 5p when the house is unoccupied during the work week. Of course that misses peak solar production time too. Its green washing, I just hate seeing people roped into something wrong when they want to do the right thing. I'm sure they offer some great financing on that beast.
