Step-by-step: how to use Propel in Solargraf:
To apply with Concert on Solargraf, you need to first integrate with your Concert credentials under settings.
To get your credentials, send an email to [email protected] with the email address where you can receive the password to that account. We recommend that you set up an email group that multiple people have access to, so that there is no risk that the email address will conflict with an existing Concert user account, for example, [email protected]. The username and password are to be updated on Solargraf as the API key username and password respectively.
Step 1: Set up integration
- Navigate to Settings > Financing > Manage Concert credentials.
