Who a 16.00 kW system suits
Typical monthly usage match: 1400–2200 kWh.
Treat as a project: export limits, transformer capacity and compliance matter as much as panel count.
What it can and cannot power
It can offset a large share of daytime household loads. It will not remove fixed network charges, and without a correctly sized battery it will not cover full load-shedding backup for high essential loads.
