WHO IT SUITS
Who this package suits
When interval data shows sustained daytime demand, a 30kW array improves the overlap between generation and spend — we model that match honestly before you commit.
-
Plant, cooling & baseload
Operations with serious daytime load — chillers, compressors, plant, and office baseload running together under the sun.
-
Large commercial roofs
Workshops and sheds where a 20kW block would leave savings on the table — more panels, more overlap with interval data.
-
Multi-site & phased growth
Owners standardising on Sungrow and iSolarCloud across sites — or planning phased expansion with one disciplined handover process.
Earlier stage or lighter loads? See the 20kW Small Business System — or compare both tiers on the commercial overview.

FAQ
Commercial solar questions
Straight answers — ask us anything else on the quote form below.
Are prices shown inclusive of GST?
Figures on this page are marked + GST. Your formal quote will show GST treatment and any exclusions (e.g. switchboard upgrades) line by line.
Who handles the grid application?
We prepare technical data and drawings for embedded generation applications and work with your retailer or consultant where required — scope is confirmed before we start.
What if our roof isn’t big enough for the package?
Panel counts are a starting point. After a site visit we may adjust strings, inverter size, or propose split arrays across multiple roofs.
Can we add batteries later?
Most commercial projects here are grid-tie for daytime savings. If storage is on your roadmap, tell us early so we can leave headroom in design and protection where practical.
Do you install outside Taranaki?
Our core commercial work is Taranaki-based. For larger regional projects, ask — we assess travel and crew capacity case by case.
