Solar Invoice, No Breakdown

I installed Solar in 2023 through a solar company. Their invoice/contract basically has one amount for everything that includes:

- Solar panels + inverter

- storage batteries

- EV charger

- home electrical subpanel upgrade (125a, required for passing inspection)

- new roof, gutters, fascia

 

I do have a separate invoice for the roof, so I can subtract that from the contract total. However, there is no breakdown beyond that. How would I go about calculating for the credit - would all of the above be eligible (minus the roof), or I need it broken down? If I need it broken down, which line items can I include? Thank you.
