What it is not
It is not a utility-rate forecast and it does not state the quantity of electricity the system will deliver.
Decision context
Why it matters
For a PPA, read the contract’s price schedule and ask how much payments increase and how often. Check the contract’s duration, early-termination costs, and what happens if the home is sold.
