WHO IT SUITS
Who this package suits
Commercial payback is strongest when generation overlaps your baseload. This tier is sized for operators who want a credible starting point — without jumping straight to 30kW.
-
Workshops & light industry
SMB workshops, light manufacturing, and trade yards with steady daytime load — where solar overlaps real usage.
-
Offices & retail back-of-house
Standalone offices and retail operations where power peaks in daylight — bills drop when generation matches the clock.
-
Your first commercial step
Businesses trialling solar before scaling — same engineering rigour and handover as our 30kW tier, sized to prove savings.

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.
