Large blocks, tall gums and roofs with a dozen faces. We map the shade on every one of them before a panel is counted, then size the battery for a house with a pool, a big heating load and a car to charge. Our own A-Grade electricians, 12 minutes away in Somerville.
Mount Eliza is the leafiest suburb we work in, and that decides how solar is done here. The blocks are large, the gums and cypress on them are older than most of the houses, and a roof that looks wide open from the driveway can lose half its winter sun to a neighbour's tree by two in the afternoon. A panel count taken from a satellite photo is close to useless on these streets. We stand on the site, look at where the shade falls in each season and design from that.
The houses add their own complications. Mount Eliza runs from 1960s and 70s originals to large renovated and architect-designed homes, many of them two storey, with cathedral ceilings, skylights, dormers and extensions added over the decades. One of our jobs here was a roof the owner described as difficult to work with, and it still took 26 panels with no conduit visible from the garden. Good design on a roof like that is mostly about choosing which faces to leave empty.
Then there is what the house uses. A pool pump running through the day, ducted heating and cooling across two levels, and more often now an EV. That is why the three Mount Eliza systems we have written up are 12.35kW, 17.1kW and 18.87kW, each with 24kWh or more of storage. You can read about everything else we do in Mount Eliza on the suburb page.
The four things that separate a Mount Eliza design from a standard suburban one.
Jinko and Aiko panels placed only on the faces that earn their keep. Each face is wired so a tree shading one in the morning does not pull down the others, and where shade moves across a single face through the day we look at SolarEdge optimisers so each panel works on its own.
Sigenergy SigenStor is what we have fitted on all three written-up Mount Eliza jobs, in three, four and five modules. GoodWe, Tesla Powerwall and Sungrow are also available. Sized so the evening heating or cooling, the cooking and the overnight base load come from the roof.
A pool pump is the easiest load in the house to move into the middle of the day. We set the timer to suit the array, set the EV charger to take surplus solar first, and size the inverter so the house can run the pump, the air conditioning and the car at once.
Two-storey access, steep pitches and raked ceilings with no roof space to hide a cable in. We plan the cable route before install day so conduit stays out of sight, and on the bay side of the Nepean Highway we use salt-rated mounting and outdoor gear.
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.
Each is written up in full with the specification and the owner's review.
The old panels came off and 36 all-black panels went on in their place, feeding a 15kW Sigenergy inverter and 40.3kWh of storage. The pool, the heating and the car now run on power made at the house.
Cathedral ceilings made for a large, complex rooftop. A 12.35kW Jinko Tiger Neo array and 24.18kWh of Sigenergy storage went in within a single day, with no conduit left on show.
Next door in Frankston South, on the same kind of treed block: 30 all-black Jinko panels and five Sigenergy battery modules, with a five metre cable run from a switchboard inside a wardrobe to the garage.
The site visit does more work here than in any flat, treeless estate.
We check each roof face for shade, note which trees are yours and which are next door, and look at the switchboard, the pool equipment and where a battery can sit.
You get a drawing showing which faces carry panels and why. A smaller array in full sun beats a larger one that spends the afternoon shaded.
One after-rebate price for panels, inverter, battery and any switchboard work. We lodge the network application and check Solar Victoria eligibility for you.
Most systems go in within a day, with a second day allowed on the largest or highest roofs. Old panels are taken down where the job replaces them.
Pool pump and EV charger timed to the array, backup circuits tested with you there, monitoring on your phone and the Certificate of Electrical Safety issued.
The battery discount and the panel certificates apply to almost every home. The state rebate has household and property limits, so it does not suit every address here.
Cheaper Home Batteries takes around 30 percent off an approved battery, with no income test. On the larger batteries Mount Eliza homes need, it is usually the biggest single item on the quote.
For eligible owner-occupiers, on solar panels and inverters only. One of our Mount Eliza jobs used the rebate and another went ahead without it. It does not cover batteries: the Solar Victoria battery rebate and battery loan closed in 2025.
Small-scale technology certificates come off the price of new panels at the point of sale, including where an old array is being replaced. If the gas heater is next, see heating and cooling in Mount Eliza.

A shaded face adds cost and very little energy. We tell you where the limit is, and one local owner noted there was no pressure to upsize.
12.35kW, 17.1kW and 18.87kW, all with Sigenergy storage, all written up with the owner's own words.
SAA accredited (Solar Accreditation Australia), New Energy Tech Approved Seller, and A-Grade electricians employed by us. Nothing is subcontracted.
We install the reverse cycle heating, heat pump hot water and EV chargers the solar will run, so the system is sized with those in mind.

Usually, but not on every face of the roof. We check the shade on site and design around it. Sometimes the right answer is fewer panels in full sun, and sometimes it is panel-level optimisers on a face that is partly shaded for some of the day.
We would not ask you to. Most Mount Eliza roofs have enough clear area once the shaded faces are left out. If one branch makes a real difference we will point it out and you can decide, keeping in mind that council rules apply to tree works on many properties here.
It depends on the pump, the heating and whether there is an EV, which is why we ask before we size. Our Mount Eliza systems so far range from 12.35kW to 18.87kW, and on the 17.1kW job the pool now runs on the roof.
Yes. On one Mount Eliza job the old panels were removed and 36 new panels with a 40.3kWh battery took their place. Older arrays usually sit on the best part of the roof, so replacing them frees that space for modern panels.
An exterior wall out of direct sun and weather works well, and two of our Mount Eliza batteries are mounted outside. We keep the battery as close to the switchboard as the rules allow to shorten the cable run.
No. It needs the right access equipment and a little more planning for the cable route, and that is allowed for in the fixed quote. Height does not change what the panels produce.
We visit, assess every roof face, and send a written quote with the layout, battery size, brands and after-rebate price. No obligation.
