Savings count avoidable variable energy charges only. Fixed municipal charges are excluded. Export credits are not assumed unless a municipality page says otherwise.

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.

Frequently asked questions

Is 16kW still a rooftop residential system?

Sometimes on large homes, but many 16kW installs are small commercial. Design and compliance differ from a typical 5kW home system.
