Error messages

Q: "Welcome to MyEnergy" is displaying after logging in. 

A: This means you are no longer active in an organization. The system recognizes that your email was tied to an account at some point but since it can not connect you to the account it shows "welcome to MyEnergy". To correct this, reach out to your admins so they can re-add you to the organization.

 

Q: I'm getting this error "It looks like the utility rate schedule for this project is not yet in our database. We're working hard to update our US utility rate database over the coming weeks.

Once loaded, recalculate the project and this should solve the issue.

 

Q: What does Internal Server Error mean? 

A: Often this error is due to the amount of information added into the project. If you have a normal project size, we typically recommend to have no more than 3-4 system options added. If you have a big commercial system it might be best to keep 1-2 system options depending on its size. 

 

Q: How can I resolve NoneType error message? 

A: Multiple factors are causing this error. This usually happens if there is missing information in your design like no quantity information in the components, no payment options added to a project, missing data in your pricing scheme, cost scheme, incentives, etc. Once you encounter this error, please send an email to OpenSolar support team including the project ID no.

 

Q: Why I was not able to generate the PDF? it shows "Document Generation Unsuccessful: Decoding to str: need a bytes-like object, float found.

1. The account is not up to date with payments
2. The account does not have any envelopes left
3. OpenSolar can not communicate with the account. 

If the account is in good standing, it is best to go into control > other > integration and API key and use the disconnect button to disconnect the integration. Once this is done, proceed to connect again.

• Go to control
• Expand Design & Hardware
• Select Setback & Design Settings
• Edit your default template
• Expand the simulation settings
• Change the Weather Dataset to the other option (EnergyPlus/PVGIS vice versa).
• recalculate the project to see if the error was resolved.
