In plain language
Use Solar cash purchase only after the cash-flow perspective, timing, contract structure, included costs, and omitted items are made explicit.
What it is not
It does not mean funds came from no external source, and a separate personal borrowing arrangement must not be silently omitted from household analysis.
Decision context
Why it matters
Confirm the same equipment and work scope, payment schedule, incentives, taxes, warranties, service, and exclusions when comparing a cash offer with financed offers.
