Four and five bedroom homes, ducted heating and cooling, and a tile roof cut into many faces. We map the roof properly, pair it with a battery sized for a full house in the evening, and install with our own A-Grade electricians.
Narre Warren South filled in through the 1990s and 2000s with the estate homes of that period: wide frontages, double garages, two living areas, four or five bedrooms and, on a lot of blocks, a second storey. The houses use a lot of energy because there is a lot of house to heat, cool and light, and most of it happens between the school run and bedtime, after the sun has gone.
The roofs match the houses. A tile roof from that era is rarely two plain faces. It has hips and valleys, a step where the garage meets the house, sometimes an upper level shading the lower one, and often an evaporative cooler sitting in the middle of the best face. A good Narre Warren South design starts by mapping every face for direction and shade, then working out how to wire them so the weaker faces do not hold back the stronger ones.
The other half of the design is the evening. When we fitted a six-zone ducted reverse cycle system for an owner here, he told us solar and a battery would be next, and that is the right way to think about it: a system that size is the main thing the battery has to carry after dark. We size storage around the heating and cooling you run, as part of everything we do in Narre Warren South.
The same four parts as any system. In this suburb the design effort goes into the first two.
Jinko Tiger Neo and Aiko panels spread across the faces that earn their place. East and west faces are often used together so the house has output from breakfast to late afternoon, with the strings arranged so shade from an upper storey affects only the panels under it.
Sigenergy SigenStor, GoodWe, Tesla Powerwall and Sungrow batteries, in the double garage where most Narre Warren South switchboards are close by. We size for dinner, the dryer, the ducted system and the overnight base load, and set up backup circuits for outages.
A hybrid inverter runs panels and battery together. We confirm whether the home is single-phase or three-phase before choosing it, because that sets the inverter, the export limit and what an EV charger can deliver.
Two-car households are the norm here. A Tesla Wall Connector, Sigenergy or GoodWe charger can go in with the system or later on a circuit we leave ready, set to use surplus solar first.
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.
Our written-up Narre Warren South job is a ducted system, not solar. These three are from Cranbourne North and Berwick, the suburbs on each side.
Twenty Jinko Tiger Neo panels split across two roof planes, a single-phase Sigenergy inverter and three battery modules in the garage. A modest array with a large battery behind it.
A five-bedroom all-electric home in Berwick with a three-phase EV charger on the same system. On a 35 degree day, one of the hottest of the year, it drew almost nothing from the grid.
34 Jinko panels across a tile roof with a Sigenergy inverter and 18.08kWh battery behind bollards, plus heat pump hot water in the same job. The main switchboard was upgraded along the way.
The roof survey does the heavy lifting on these homes, so that is where we spend the time.
Every face measured for direction, pitch and shade. We also list the big loads: ducted heating and cooling, hot water, cooking and any car.
You see which faces are used and why, and how the panels are grouped so one shaded section does not pull the rest down.
Storage is sized from what the house runs after dark, with the backup circuits agreed at the same time.
One after-rebate price. Solar Victoria eligibility, federal discounts and the network application are handled by us.
Height access for double-storey roofs, panels, inverter and battery by our own crew, then the app, the backup test and the Certificate of Electrical Safety.
On a family-home system the battery discount is often the largest line, and the Solar Victoria rules decide the rest.
Small-scale technology certificates apply to eligible solar and scale with the size of the array. They are deducted at the point of sale.
Around 30 percent off an approved battery under Cheaper Home Batteries, with no income test. It applies whether the battery goes in with new solar or onto an existing system.
For eligible owner-occupiers, on solar panels and inverters only. It has household and property limits, so some homes here qualify and some do not. There is no Solar Victoria battery rebate or battery loan, as both closed in 2025.
We install the ducted systems in this suburb as well as the solar, which takes the guesswork out of sizing.
Our six-zone ducted job is in Narre Warren South. When the same crew does the solar, the two are designed to fit. See heating and cooling in Narre Warren South.
Hips, valleys, two levels and rooftop plant are normal on our jobs in Casey. The layout is drawn and explained before you commit.
Accredited through Solar Accreditation Australia, a New Energy Tech Approved Seller, with Powerband A-Grade electricians on every install.
Solar now with the battery or EV charger later is fine. We leave the inverter capacity and the circuits ready so the second stage is simple.

Usually, yes. Most Narre Warren South roofs have enough area once east, north and west faces are combined. What matters is how the panels are grouped. We show you the layout and expected output for each face before quoting.
Yes. We lay the array out around rooftop units and keep panels clear of the shade they cast. If you later change to reverse cycle cooling, the layout can be extended.
It depends on what runs after sunset. A home with ducted reverse cycle, an electric oven and a dryer in use most evenings needs more than one that is still on gas. Nearby family homes on this page carry between 18.08kWh and 40.3kWh.
If you expect to replace the gas heater within a few years, yes. The cost of a few more panels and a larger inverter now is small next to redesigning later.
They can share it. The charger is set to use surplus solar first, and we check the supply to the house to see what charging rate it will support alongside everything else.
A straightforward system is often done in a day. Larger arrays on two levels can run into a second day, as a 13.3kW three-phase job of ours in Berwick did. The quote states the time for your house.
