A shed roof, a three-phase supply and a long run back to the house: this is ordinary work for us in Cranbourne South. Jinko panels, GoodWe and Sigenergy storage, designed for properties that run pumps, workshops and no mains gas, 18 minutes from our Somerville depot.
Cranbourne South does not look like the rest of Cranbourne. South of the estates the blocks open out into acreage, horse properties and lifestyle land, with long driveways, big machinery sheds and a house set well back from the road. A solar design that works on a suburban street does not carry over. The house roof may be shaded by a windbreak while a shed 50 metres away has a long, clear, north-facing roof with nothing on it.
So we start by walking the property. Which roof gets the sun, where the main switchboard and any sub-boards are, whether the supply is single or three-phase, and how far apart all of those sit. On one Cranbourne South job the answer was 28 panels along the shed roof, a three-phase GoodWe inverter and six battery modules on a new concrete pad against the wall. Distance matters here: cable has to be sized for the length of the run, and that is worked out before the quote, not found out on install day.
Many properties here have no mains gas. Hot water, heating, bore and tank pumps and the workshop all sit on the electricity meter or on LPG bottles, which is why batteries in Cranbourne South tend to be large. The suburb also has conventional homes on residential streets and in lifestyle villages, and two of our three local jobs were on tile-roofed houses. Read more about our work in Cranbourne South.
The components are the same ones we fit in town. The design work around them is what differs.
Jinko and Aiko panels on tin shed roofs, Colorbond and tile. A shed roof is usually one long plane at a low pitch, which is quick to fit and easy to keep clear of shade. We check the purlins and sheeting before committing to a layout.
GoodWe, Sigenergy, Sungrow, SolarEdge and Fronius units matched to the supply. On three-phase the inverter balances output across the phases, so a welder or a pump starting on one phase is still covered by the solar and the battery.
GoodWe, Sigenergy and Tesla Powerwall storage on a concrete pad or a garage wall, out of the weather and clear of vehicles. With room to spare, the battery can be sized to the property instead of to the space available.
On tank water, losing power means losing water pressure. We set up backup circuits so the pressure pump, fridge, lights and internet keep running from the battery when the grid is down, and test the changeover with you.
The full range is on our products page.
Tier-one panels with 25-year performance warranties, laid out for the roof faces you have.
Hybrid and string inverters, chosen so a battery can join the system now or later.
Home batteries sized to the evening peak, with backup circuits set up for outages.
Home chargers wired into the same system and set to charge from your solar first.
Three different properties in the one suburb. Each write-up has the full parts list.
28 Jinko Tiger Neo panels across the shed roof feed a three-phase GoodWe inverter and six GoodWe battery modules, set on a new concrete pad against the exterior wall. No Solar Victoria rebate was used on this one.
A double-storey, three-phase home with 14 Jinko Tiger Neo III panels, a GoodWe inverter, two battery modules behind bollards in the garage and a 22kW EV charger. The main switchboard was upgraded as part of the job.
26 Jinko Tiger Neo panels on an open tile roof, a single-phase Sigenergy hybrid inverter and three SigenStor modules mounted on an exterior wall.
More of the work happens before install day than on a suburban job.
Every roof worth considering, the main board, sub-boards in sheds, the supply type and the distances between them.
Pumps, workshop gear, hot water, heating and any EV. Motor starting loads are noted because they shape the inverter choice.
Trenching or overhead, cable size for the distance, pad location and panel layout, all in the fixed quote.
Export limits on rural lines can be lower than in town. We apply first and design to the approved figure.
Our own electricians fit the system, test backup with the pump running and set up monitoring on your phone.
The schemes are the same as in the suburbs, but shed installs and second dwellings raise questions worth checking early.
Small-scale technology certificates reduce the price of the solar panels at the point of sale, wherever on the property the panels are mounted.
Available to eligible owner-occupiers for solar panels and inverters only. One of our three Cranbourne South jobs used it and two did not. It has not covered batteries since the battery rebate and loan closed in 2025.
Cheaper Home Batteries gives around 30 percent off an approved battery with no income test. On a large battery it is the biggest line on the quote. For LPG and wood-heated homes, see also heating and cooling in Cranbourne South.
Our depot in Somerville is surrounded by the same sort of country: orchards, horse properties and sheds on three-phase.
Two of the three Cranbourne South systems on this page are three-phase. It is not a reason for the quote to stall.
Trenching, conduit and correctly sized cable are measured at the site walk and included in the fixed quote.
SAA accredited through Solar Accreditation Australia and a New Energy Tech Approved Seller. Powerband employees do the install.
Close enough for a second site walk if the design changes, and for the same crew to return after handover.

Something specific to your property? Call 0466 355 441 and an electrician will talk it through.
Yes. We did this in Cranbourne South with 28 panels on a shed roof. The inverter and battery sit wherever suits the property, and a correctly sized cable links them to the main switchboard.
There is no fixed limit, but the longer the run, the heavier the cable needs to be to keep voltage drop within the rules. We measure it and price it at the site walk.
It changes the equipment, not the outcome. A three-phase hybrid inverter and a compatible battery cover all three phases. We have fitted three-phase systems in Cranbourne South with both 16.64kWh and 49.92kWh of storage.
If the pump is put on a backup circuit, yes. We check the pump's starting current against the inverter's backup rating and test it before we leave.
Bigger than a comparable house on gas, because hot water, heating and cooking are electric or about to be. We size from your actual loads and bills, including LPG, and show the working.
Yes, subject to the village's own rules on roof and wall-mounted equipment. We find out what management requires before quoting.
We look at every roof, the supply and the distances, then send a fixed written quote with the layout, cable runs, battery size and after-discount price. No obligation.
