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?
