Good news for legacy solar customers and the contractors working with them: solar system expansion projects (defined as retaining existing panels while adding panels and/or battery storage) no longer require a new PTO under GoGreen Home rules. That means your pre-2023 customers can use GoGreen Home to upgrade their systems without jeopardizing their NEM 2 status.
Here’s the breakdown of what’s required for brand new projects vs. expansion projects:
1. New Solar Projects
For new solar + battery installations, the following is required for project completion and payment:
- Interconnection application with utility (see acceptable forms of proof)
- Certificate of Completion signed by the customer
- Closed permit
The following is required for QA/QC of new solar + battery installations and may be requested up to 1 year after project completion:
- Permission to Operate (PTO)
2. System Expansion Projects
For expansions of existing solar systems (e.g., retaining existing panels while adding panels and/or battery storage), a new PTO is not required. The following is required for project completion and payment:
- Evidence of existing NEM agreement with utility (e.g., NEM charges on utility bill)
- Certificate of Completion signed by the customer
- Closed permit
The following is required for QA/QC of solar expansions and may be requested up to 1 year after project completion:
- Proof of PTO for original system
Quick Guide:
New systems
Interconnection application + COC + closed permit required for payment. PTO required up to 1 year after installation for QA/QC.
Expanded systems
Evidence of existing NEM agreement + CoC + closed permit required for payment; proof of original PTO required up to 1 year after installation for QA/QC.
