The purpose of this stage is to document PTO, complete customer onboarding, confirm the system is energized and visible in Daylight’s Solar portal, and finish the project closeout requirements.
Step 1: Upload the PTO Approval Letter
Once PTO is received from the utility, upload the final approval letter in the PTO Approval Letter section.
The document must clearly show that the utility has approved the system to operate.
Do not upload:
An interconnection application
A submission confirmation
A meter-work notice
A document showing that PTO is still pending
Daylight will review the uploaded letter and approve or return it for correction.
Step 2: Send the Customer Onboarding Invite
Click Send Customer Invite.
This sends the customer an invitation to complete Daylight onboarding and configure their payment account.
The portal will show Customer Onboarding Completed once the customer finishes the required setup.
If onboarding remains incomplete, follow up with the customer before project closeout.
Step 3: Complete the ITC Commissioning Checklist
Complete the required commissioning checklist in the portal.
The system should be commissioned using Daylight’s connected Sol-Ark portal account whenever possible.
Commission the system using the Daylight installer login provided for commissioning.
Confirm the inverter and batteries appear online in the Solar portal.
Confirm production and equipment status are visible.
Make sure there are no blocking alarms, communication errors, or offline devices.
If the system was commissioned under another account, transfer or share the system with [email protected] so Daylight can verify system status and production.
The next closeout steps will remain locked until the checklist is completed and approved.
Step 4: Upload Proof of an Energized System
Once the commissioning checklist is approved, upload proof that the system is on and producing.
Acceptable proof includes:
A photo showing the inverter in the ON position
A photo of the inverter display showing solar production
A screenshot from the Solar portal showing the system online and producing
The proof must belong to the correct project and clearly show that the system is live.
Click Submit Photo for Review.
Step 5: Confirm Daylight Solar Portal Access
Daylight must be able to view the system in the connected Solar portal before final approval.
Confirm:
The correct customer and project are connected
The inverter and batteries are reporting
Solar production is visible
Equipment status is healthy
The system has been transferred or shared with [email protected], when required
If Daylight cannot see the system in the Solar portal, investigate the equipment and monitoring connection before contacting Daylight.
Missing access, offline equipment, or incomplete production reporting may delay final approval and payment.
Step 6: Generate and Sign the Final Completion Certificate
Once the required PTO and commissioning items are approved:
Click Generate Certificate.
Review the Final Completion Certificate.
Complete the required signature process.
The certificate confirms that the project has been completed and is ready for final closeout.
Step 7: Generate and Sign the Release of Claims
Click Generate Release of Claims.
Review and sign the document through the portal’s signature workflow.
The Release of Claims must be completed before the certificate package can be submitted.
Step 8: Submit the Certificate Package
Before submitting, confirm:
PTO Approval Letter is uploaded and approved
Customer onboarding is complete
ITC Commissioning Checklist is complete
Daylight can view the system in the Solar portal
Proof of energized system is uploaded and approved
Final Completion Certificate is signed
Release of Claims is signed
Submit the completed certificate package for Daylight review.
If anything is incomplete, inaccurate, or belongs to the wrong project, the package will be returned for correction.
Step 9: Complete the Final Milestone Invoice
Once the certificate package is approved, the applicable final milestone invoice will become available for signature.
Complete and sign the invoice in the portal so it can move into payment processing.
