A first system for a 1970s brick veneer, or more panels and a battery for a Keysborough South home that has outgrown what the builder left. Jinko and Aiko panels, Sigenergy, GoodWe and Tesla storage, installed by our own A-Grade electricians.
Ask someone where they live in Keysborough and the answer tells us most of what we need to know about their solar. The northern half is the original suburb: 1970s and 1980s brick veneer, single storey, on a decent block with a plain hipped tile roof. To the south are the estates built since about 2010, where the homes are large, modern, frequently two storey and set close to the boundary. Same postcode, opposite problems.
In older Keysborough the roof is rarely the obstacle. There is usually a generous north or west face with little on it, and many of these homes have never had panels. The work is in the electrical system, because a 45-year-old switchboard has to be replaced before it can take a battery. In Keysborough South the board is modern and the garage is ready for a battery, but the roof is divided into small faces and may already carry a small system that came with the house.
So the first job is working out which conversation we are having: a full new system on a simple roof, or making more of a complicated one. Both end in the same place, with enough generation and storage to cover the evening and whatever is still to be electrified. The suburb page has more on what else we do in Keysborough.
One crew and one set of brands. What changes is where the effort goes.
On a 1970s or 80s Keysborough brick veneer we can usually fit a full array of Jinko Tiger Neo or Aiko panels across one or two faces of the tile roof, with a hybrid inverter and battery from the start. These are simple, productive roofs, and the layout tends to be tidy.
Estate homes often have a small array from the builder and a lot of unused roof on other faces. We assess what is there, add panels where the sun reaches, and either work alongside the existing inverter or replace it with a hybrid unit that also runs a battery.
Sigenergy SigenStor, GoodWe, Tesla Powerwall and Sungrow. In the newer homes the battery goes on the garage wall behind bollards. In the older ones we pick a shaded outside wall near the meter box. Backup circuits are chosen with you and tested before we leave.
Older Keysborough homes generally need a new switchboard and we build it with capacity to spare. Keysborough South homes usually do not, which makes adding an EV charger easy. We fit the Tesla Wall Connector and Sigenergy and GoodWe chargers, set to use 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.
We have not published a Keysborough case study yet. These are from Chelsea Heights, Chelsea and Mordialloc, a short drive south and west.
A double-storey home in Chelsea Heights with 16 Jinko Tiger Neo III panels on a tin roof, a GoodWe hybrid inverter, three GoodWe battery modules in the garage and a 7kW GoodWe car charger. The existing switchboard did not need upgrading.
In Chelsea, Jinko Tiger Neo panels across two planes of a tile roof feed a Sigenergy hybrid inverter and 16.12kWh of SigenStor storage mounted on a brick wall.
A Mordialloc tile roof with 28 Jinko Tiger Neo III panels, 24.96kWh of GoodWe storage on the southern wall beside the switchboard, and the gas cooktop replaced with induction on its own circuit.
Keysborough is about 30 minutes from our depot in Somerville.
An existing system or none, gas appliances, an EV or plans for one. A power bill helps us see when you use energy.
Roof faces and shade, the condition of the switchboard, the existing inverter if there is one, and the best battery position.
A layout drawing and a fixed quote with brands, sizes and discounts shown line by line.
Network connection approval, Solar Victoria where you are eligible and the federal discounts are all submitted by us.
Our employees do the whole install, generally within one or two days, then walk you through the app and the backup circuits.
If you are adding to an existing system, some of these apply differently. We check your situation before quoting.
Available to eligible owner-occupiers for solar panels and inverters. It does not cover batteries: the Solar Victoria battery rebate and battery loan both closed in 2025. Eligibility for homes that already have solar has its own rules, which we check for you.
Around 30 percent off an approved battery through Cheaper Home Batteries. It is federal, has no income test and applies whether the battery joins a new or an existing solar system.
Certificates created by new solar panels, deducted from the price at the point of sale.
Old switchboards and existing systems are where the time goes. We are set up for both.
An existing array is not ripped off by default. If it is sound, we build around it and tell you honestly when replacing it makes more sense.
We are A-Grade electricians before we are solar installers. Rebuilding a 1970s board is routine, and it is done by the same crew on the same job.
SAA accredited, a New Energy Tech Approved Seller, and every person on site is employed by Powerband.
We also install reverse cycle heating and cooling in Keysborough, heat pump hot water and EV chargers, so the solar is sized with those in view.

It depends on the age and type of the inverter and the condition of the panels. Often we keep the original array and add a second one with a hybrid inverter and battery. If the old inverter is near the end of its life, replacing it is tidier. We check before recommending.
Usually, yes. The battery is connected either alongside your current inverter or through a new hybrid inverter. The federal battery discount of around 30 percent applies in both cases.
Mostly the switchboard. Original boards with old fuses are not suitable for a battery or backup circuits, so we replace them as part of the job. The roof on these homes is normally well suited to panels as it is.
Keysborough is in the City of Greater Dandenong. It makes no difference to the incentives: Solar Victoria and the federal discounts are based on your eligibility and the equipment, not the council.
Generally it will. We use the faces that get good sun, and current panels produce enough that three or four smaller groups make a solid system. You see the layout and expected output before agreeing to anything.
Yes. We install Tesla Wall Connector, Sigenergy and GoodWe chargers and set them to prefer solar. If the car is still a plan, we leave the circuit capacity and the wall space for it.
A site check of the roof, switchboard and any existing system, then a written quote with layout, battery, brands and the price after discounts. No obligation.
