Bottom Line
Federal ITC and state rebates change in 18-24 month cycles. Model the business at the post-rebate price point so it survives policy whiplash. Operators who plan around this constraint from day 1 — not as an afterthought in year 2 — are the ones who get to a healthy year-3 P&L in this category.
