If you are submitting a battery-only project and the original solar system already has PTO (Permission to Operate), please follow the documentation guidelines below. Since the utility has already granted PTO for the solar array, a new PTO is not required for the battery portion unless mandated by your local utility or AHJ.
Required Documents – Battery-Only Submission
Proof of Original PTO (Solar System Only)
| Upload a copy of the original PTO or utility approval showing that the solar system is active and operational. |
Battery Permit | Upload the approved permit for the battery installation. |
Proof of Passed Battery Inspection
| Submit documentation showing that the battery installation passed final inspection. |
Battery-Specific Contractor Lien Waiver
| A lien waiver confirming that the installer/contractor has acknowledged work completion for the battery portion. |
Fund Release – Customer Approval Confirmation | The customer must approve the fund release. |
Proof of Battery Operating/Commissioned | Provide confirmation that the battery is commissioned and operational, which may include screenshots, utility meter activation notice, commissioning certificate, or monitoring proof. Important Reminders If this is a battery only and customer has no solar we do not need any solar PTO information |
