What the free tool cannot assess
This estimator is deliberately simplified. A bankable, investment-grade and compliance-ready outcome needs NZC Portal and NZC Solar engineering.
Structural capacity
DNO / G99 requirements
Half-hourly self-consumption profile
Tenant PPA billing
Service charge recovery
Carbon reporting ownership
NZCBS contribution
Formal MCS design
For a full commercial assessment, use NZC Portal or speak to NZC Solar.
Who claims the carbon — landlord or tenant?
See how NZC Solar allocates financial value and carbon evidence across ownership, PPA, service charge and export models.
