I think a medium install would work for my current situation. I’m wondering if I want to add powerwall or other branded battery packs later to the setup, is that possible?
The Tesla software is only gonna work with their products only, right?
My understanding is that the IRS has clarified that PWs (or similar tech from other companies) are covered by the ITC, even if they are installed later, as long as they meet the eligibility rules - with the main one being that they are only charged from the solar panels (or other qualifying source.) This had been a question in the past. Of course, the residential ITC is currently scheduled to drop to 22% next year before ending, so there is definitely a time component.If PowerWalls are included in the installation, they are covered by the 26% us tax rebate.
If added later, you may not get the tax rebate.
You’ll lose the bundle discount and the tax credit only applies to storage when it is installed with solar. So you are going to pay way, way more.

In the end this is the most important thing. However, for those looking for more information or something to take to their tax advisor:tl;dr: Speak with a professional before taking tax advice from the internet
The Battery is expected to have a storage capacity of 13.5 kilowatt hours (“kWh”) and a power rating of 5 kilowatts (“kW”).

Rumor has it the party requesting that Private Letter Ruling was Lyndon Rive.So, we can make a pretty educated guess this was actually somebody adding a Tesla PW.
My bad should’ve been more careful. I meant paired with. Power walls alone I don’t believe qualify. If you connect it to a solar system you can get the credit.My understanding as well is what @gpez is saying... but that doesnt directly contradict what @Zer0t is saying.
Semantics, I know, but @Zer0t said "the tax credit only applies when storage is installed with solar". I read that as installed = "paired with".
What we basically understand at this point is, storage is allowed to claim the tax credit in place for the year the storage is installed, as long as the storage is mated with, and charged from solar. That fits the definition of "installed with" solar, but does not mean that it has to be installed "at the same time" as solar.
So, if you get powerwalls, as long as you are charging them from a solar install that either previously existed on the home, or is being installed at the same time, you can claim the tax credit for the storage. At least, thats how I understand it based on the research I did. I intend to claim the tax credit of 26% for the powerwalls I installed this year that are paired with solar that was installed in 2015.
Still, for this OP, the cost to install "later" is going to be more than the cost to install "now, when solar is being installed". The only reason I might wait is, I have no idea if tesla is going to come out with something new for powerwalls in battery day. They sure are making it enticing to buy them "now" for example.
My bad should’ve been more careful. I meant paired with. Power walls alone I don’t believe qualify. If you connect it to a solar system you can get the credit.
Again being quick on an iPhone. You are going to way more without the package discount. My discount for solar and PW together is 7100 bucks. That’s a big chunk of change.Thanks for clarifying, @Zer0t but I'm confused why you then said "So you are going to pay way, way more." when the OP clearly mentioned pairing the PWs with a medium solar install after.

my contract reads:
3 Powerwalls and tax 20,394.38
Powerwall supporting hardware 1,100
Powerwall installation 4,000
Powerwall + Solar discount (7,100)
Total 18,394.38
I know there’s been some pricing changes (stuff has gotten cheaper) so maybe they’ve gotten rid of the discount?
