Why a company's own figure can differ from this one
- Timing. These prices come from state incentive filings, published about once a year, so the latest full year here is the last year of data. Prices moved down in many states after 2023; a company's current quotes can be lower (or higher) than its last full year on record.
- Dates. A filing is dated when the program processed it, not when the job was sold, so jobs can land in a different month or year than in the company's own books.
- What the price includes. The filed price is the whole project as reported to the program, which can include loan dealer fees, electrical panel upgrades or roof work. A company's internal figure often leaves those out.
- Batteries. Systems flagged with a battery are excluded here; a battery the filing didn't flag can still raise a year's median.
