A solar project can involve a tax filing, state incentive registration, municipal building and electrical permits, utility interconnection, renewable certificate registration, and closeout records. Not every document applies to every project.
Forms are not approvals
Downloading or filing a form does not guarantee a credit, incentive, permit, interconnection approval, or permission to operate. Confirm eligibility, deadlines, ownership, and the responsible filing party before construction.
Local forms still require the project address

The national and state directories below help identify the correct agency, but the contractor must verify the final forms for the address.
