Where Solar Trailer Co units work

Dairy and beef farms

Replace generators on shed and pump duty. Pair with the irrigation pump module for stock or crop water from creek, tank or bore.

Diesel costs on a working farm pile up — and many farms are running gensets near houses, calf sheds and during quiet hours when noise matters. A Solar Trailer Co unit drops in silently, runs all day on solar, and sits inside council noise limits where diesel cannot.

• Taranaki dairy — Tier 1 + comms, ~NZ$4,200/yr diesel cut.
• Manawatū lifestyle block — Tier 1 with EV charger module.
• Frost-fight booster across a 6 ha block via irrigation module.
• Calf-shed top-up over a wet spring.

Tier 1 — Solo covers most farm draws. Tier 2 — Crew if you need split-phase or larger storage.

Residential builds

Tool charge bench, 240 V outlets, lockable tool wall. Subdivisions before mains is in. Renovations with no street power.

Frame crews charging overnight on-site, no diesel haul, no early-morning generator noise from the neighbours. Tier 1 sizes for a small frame crew; Tier 2 covers an 8-house residential build.

• Queenstown architect home — Tier 1 + tool kit module.
• Two-stage subdivision build before mains is in.
• Frame crew of 8 charging overnight on-site.
• Renovation with no street power.

Roading and civil

Quiet variable-message-board and tower-light power for night work near homes. Sits inside council noise limits where diesel cannot.

Council noise rules push diesel generators out of residential-adjacent civil work. Solar Trailer Co units carry the comms, VMS boards, tower lights and tool charging silently, with battery storage sized for 1.5–2 days of zero-sun operation.

• Wellington bridge piling sub-base — long-term Tier 3 hire.
• Cycleway lighting & comms — 6-month run.

Festivals and events

Silent stage power, vendor-row charge bays, EV-arrival charging on one chassis. Drops the on-site diesel count and the noise floor at the same time.

Festival production teams use Solar Trailer Co units for vendor row, stage-side power, EV-arrival charging and comms. Silent, council-friendly, and pairs with the espresso & hospitality module for ~600 coffees a day on solar alone.

• Splore — vendor row, 4 trailers, full event.
• Rhythm & Vines — Stage 3.
• Auckland NYE — 2 trailers, council-approved.
• 500-pax outdoor wedding — 6 hours, silent.

Off-grid lifestyle

Bach, lifestyle block, remote cabin. Silent solar power with battery storage sized for 1.5–2 days of typical site load with zero solar input.

For owners who want to step off-grid without a 24/7 generator. Tier 1 sizes for one-operator draw — small workshop, electric tools, EV charging, water pump, induction cooking. Bad-weather backup via hybrid LPG module rental.
