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, can run through the day on solar in good conditions (runtime depends on load, sunlight and battery size), and sits inside council noise limits where diesel cannot.

• Dairy shed — Tier 1 + comms; illustrative fuel saving on the order of $4,000/yr (depends on runtime and fuel price).
• Lifestyle block — Tier 1 for house and workshop loads.
• Frost-fight booster across a 6 ha block via irrigation module.
• Calf-shed top-up over a wet spring.

Tier 1 — Solo (1.43 kW solar, 5 kWh battery, 6 kW inverter, 16 A switchboard) suits lighter farm draws. Tier 2 — Crew (2.85 kW solar, 10 kWh battery, 16 A / 32 A switchboard) if you need a 32 A circuit or larger storage. Both are available on a trailer or on skids.

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 suits a small frame crew; Tier 2 steps up to 2.85 kW of solar, 10 kWh of storage and a 16 A / 32 A switchboard for a larger build. Sizing is indicative — we confirm it against your actual load profile on enquiry.

• Architect home build — 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 — actual runtime varies with site load and battery size.

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

Festivals and events

Silent stage power and vendor-row charge bays on one chassis, through a 16 A / 32 A switchboard on Tier 2 and Tier 3. 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 and comms. Silent, council-friendly, and pairs with the espresso & hospitality module for high-volume espresso service — up to ~600 coffees a day in good conditions (actual output depends on sunlight, load and battery size).

• Festival vendor row — several trailers over a full event.
• Multi-stage festival — stage-side power.
• City New Year's Eve event — multiple trailers.
• 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 — actual runtime varies with site load and battery size.

For owners who want to step off-grid without a 24/7 generator. Tier 1 suits a one-operator draw — small workshop, electric tools, water pump, induction cooking — on 1.43 kW of solar (expandable to 2.85 kW), 5 kWh of storage (expandable to 10 kWh) and a 6 kW inverter. For a permanent install, the same build is available on skids instead of a 2.4 m trailer, at a lower cost. Bad-weather backup via hybrid LPG module rental.
