Solar and battery Mount Martha VIC 3934

Solar sized for an all-electric Mount Martha home

Sloping blocks, roofs turned towards the view and three very different kinds of house. We design each Mount Martha system for the load the home will carry once heating, hot water and cooking are electric. Installed by our own A-Grade electricians from Somerville.

Solar in Mount Martha

The roof faces the bay. The sun is behind it

Houses in Mount Martha were built to look at the water. On the slopes above the Esplanade that often means the big roof faces point west or south-west towards the bay, and the north face is the small one at the back, cut into the hill or shaded by the trees upslope. So a Mount Martha design rarely starts with a neat north-facing rectangle. It starts with working out how much each face produces across the day, and a west face is more useful than people expect, because it is still generating when the household gets home.

There are really three suburbs here. The older beach houses near the village and South Beach have small, simple roofs and often an old switchboard. The 1990s and 2000s estate homes inland towards Bentons Road have hipped tile roofs with room for a solid system, and many carry a small early array that is now undersized. The large newer homes have big roofs, modern boards and big loads to match. Each needs a different size and a different battery position.

What ties them together is where the house is heading. Our written-up Mount Martha job is a home where heating, hot water and cooking are all electric and the gas line is gone, carried by 15.2kW of solar and a 24.18kWh battery. We size for that end point even if you are only doing the solar this year. See our full range of work in Mount Martha.

What we install in Mount Martha

Matched to the slope, the era and the load

Hardware we stock parts for, fitted by Powerband electricians.

01

Arrays for east, west and awkward faces

Jinko Tiger Neo and Aiko panels spread over the faces that work, with each orientation on its own input so a west face and an east face both run at their best. On steep sites we plan access and anchor points before the day.

  • East and west faces used well
  • Jinko and Aiko panels
  • Steep-site access planned
02

A battery sized for electric heating

Once the heater, hot water and cooktop are electric, the evening load is larger than a gas home ever had. Sigenergy SigenStor is modular, so a battery can start at three modules and grow. GoodWe, Tesla Powerwall and Sungrow are the alternatives we fit.

  • Modular, room to expand
  • Sized for the evening peak
  • Federal battery discount applied
03

Upgrades to early systems

Mount Martha went solar early, and many estate homes have a small array with an ageing inverter. We test it, then either add a battery and hybrid inverter to what is there or replace the lot with a full-roof system.

  • Existing system tested
  • Fronius and Sungrow inverters
  • Old array removed if replaced
04

Backup and coastal hardware

Wind off the bay brings both salt and outages. Mounting, isolators and enclosures are salt-rated on homes near the water, and backup circuits keep the fridge, lights and internet running when the grid drops.

  • Salt-rated mounting and gear
  • Backup circuits chosen with you
  • Battery under cover

How a Mount Martha install runs

Start with where the house is heading

Five steps, and the first one is a conversation, not a measurement.

Drone view of a rooftop solar array installed by powerband electrical
  1. 01
    Ask what will be electric in five years

    Heating, hot water, cooktop, a car. The answers set the array and battery size more than the last power bill does.

  2. 02
    Survey the roof and the slope

    Orientation and shade on each face, roof material, access on a sloping site, the switchboard and the supply type.

  3. 03
    Design, price and stage it

    A layout and one fixed after-rebate price. If you want solar now and the battery later, the inverter is chosen so the battery connects without rework.

  4. 04
    Approvals, then install day

    Network application and rebate paperwork lodged by us. Our local job went in within a single day.

  5. 05
    Tune it after the first bill

    Monitoring is set up at handover. On our Mount Martha job the bill kept falling after the settings and plan were tuned, so we check in once the system has run a while.

Rebates in Mount Martha

Two federal discounts and one state rebate

They stack, but each covers a different part of the system.

01
STCs on solar panels

Federal small-scale technology certificates reduce the price of the panels at the point of sale. There is nothing for you to claim afterwards.

02
Cheaper Home Batteries

The federal battery discount, around 30 percent off an approved battery, with no income test. It applies whether the battery goes in with new solar or onto an existing system.

03
Solar Victoria, panels and inverter only

A rebate and interest-free loan for eligible owner-occupiers. Batteries are not covered, since the Solar Victoria battery rebate and battery loan closed in 2025. Planning to electrify the heating too? See heating and cooling in Mount Martha.

The whole experience of working with Powerband has been fantastic. From the get go they were helpful with the design, requirements and answering all the questions we had about the install. We couldn't be happier with choosing them for the job. Special thanks to Bailey and the team for getting the entire installation done in one day it was a huge job so for it to be done and to such a high standard is much appreciated Thanks everyone at Powerband for all you've done

We have just had a Braemer Dominator reverse cycle ducted system installed by the Powerband Electrical team to replace our gas-fired system. We were very happy with the whole process, from the sales/design discussions with Dayle to the installation by the team led by Julian and including Logan and Darren. Using the existing ducting had its challenges but the team overcame them well. Julian set up the AirTouch5 control system & zoning with us and with a sudden cold snap arriving it has proven simple to use to create a comfortable environment. In fact we are already finding it far more effective system than the considerably larger gas unit and a more uniform heat with less draughts. Thanks to the Powerband team. Ken in Glen Waverley

Petris and his electrical team did 2 inverter airconditioner installs as part of our whole solar system install. Great workers, good thinkers who could sort out a couple of small issues in short order and wonderful people to have around our house. Organised and professional. Highly recommend Powerband.

Had the Powerband team electrify out whole house. Updated the heating / cooling with split systems, replace gas cooktop & hot water and put solar on with a 30kw battery. No gas bill, solar is producing more energy than we consume. These days we barely even have the supply charge. As part of it, they put the package together of what we wanted and needed to future proof our house and showed us several options for paying for it, in the end we opted for a 5-year interest free loan. Looking at our numbers, most of the loan will be paid off from the savings from our gas and electricity savings. All the work and upgrades done and barely any out of pocket cost, nice.... The team were great - worked in with timing for the jobs when it worked for us. The boys on site were all great, friendly, polite and professional. Did the job well and packed up (and cleaned up) well. Happy to recommend Powerband to anyone wanting to electrify their house in a cost-effective way.

FAQ

Mount Martha solar questions

Anything else, call 0466 355 441. You will get an electrician on the phone.

My Mount Martha roof faces west to the bay. Is that a problem?

No. A west face produces a little less over the year than a north one, but it produces later in the day, when a household is home and using power. Many of our coastal designs lean on east and west faces together.

How much solar does an all-electric home need?

More than a gas home, because heating, hot water and cooking all move onto the meter. The Mount Martha home on this page runs entirely on electricity with 15.2kW of solar and 24.18kWh of storage. Yours is sized on its own roof and usage.

Can I install solar now and go off gas later?

Yes, and it is a sensible order if the gas appliances still have life in them. Tell us the plan and we size the array and inverter for it, so nothing has to be replaced when the heater or hot water unit is changed.

Will panels on a steep block cost more to install?

Sometimes a little, where extra access equipment is needed. It is assessed at the site visit and included in the fixed price, so there are no additions on the day.

I have an older 3kW or 5kW system. Keep it or replace it?

We test it first. Sound panels with a working inverter can stay and take a battery. A small array on the best face of the roof is often worth replacing, because modern panels get far more from the same area.

Does the battery work in a blackout?

When backup circuits are set up, yes. The circuits you choose stay on, and the panels keep charging the battery during daylight. We test it with you at handover.
