The complete record
From a label on the wall to a result you can hand to a contractor.
01
Establish ownership
Cash and loan owners continue. Lease and power-purchase agreement customers receive guidance for their contractual route.
02
Recover access
Use a current manufacturer playbook and an identifier you read from your equipment. There is no portal-password collection.
03
Connect read-only data
Authorize only the production access your manufacturer provides. You can revoke it in one action.
04
Read the range
Actual production is compared with a model using historical weather. The result includes uncertainty, source, window, and limits.
