Off-Grid Solar & Battery Systems
Off-Grid Solar Albury-Wodonga: Stand-Alone Power Systems
Locally designed for Albury-Wodonga’s rural properties, with a load profile built around your actual energy use — not a generic package.
What Is Off-Grid Solar
A stand-alone power station for your property
An off-grid solar system generates and stores 100% of a property’s power with no connection to the electricity grid at all. It pairs solar panels with a bank of solar batteries — traditionally deep cycle, increasingly lithium — sized to run the home for three to five days on stored charge alone, backed by an auto-start generator for extended low-sun periods.
It’s the right fit for homes in semi-rural, rural or remote parts of the Albury-Wodonga region where there’s no practical grid access, or where the cost of a new connection — particularly on long SWER (Single Wire Earth Return) lines — makes going off-grid the more sensible investment.
Get it wrong, though, and an undersized system means running the generator every second night. Designing a stand-alone system is very different to a grid-connected or hybrid one: we factor in ALL your energy usage, so as part of your initial consultation we’ll ask you to complete a load profile sheet.
Off-Grid vs Hybrid vs Grid-Connect
Which type of system actually fits your property?
This is the single most common point of confusion we hear on-site. Here’s the real difference, side by side.
| Grid-connect | Hybrid | Off-grid | |
|---|---|---|---|
| Grid connection | Yes, always | Yes, always | None — fully independent |
| Battery | Not required | Yes, sized for short backup | Yes, sized for full autonomy |
| Backup generator | Not applicable | Optional | Strongly recommended (auto-start) |
| Best suited to | Urban/suburban with reliable grid access | Outage protection without full off-grid cost | Remote or high grid-connection-cost rural properties |
How It Works
The four parts of a properly designed off-grid system
Solar panels
Sized to your daily load, not a stock system size
Battery bank
3–5 days of stored autonomy, built to your load profile
Inverter
Converts stored power for every circuit in the house
Auto-start generator
Fallback during extended low-sun stretches
Is Your Property Suited
Four things we assess before quoting anything
Solar resource
Average daily sun hours and shading across an Albury-Wodonga winter versus summer.
Roof & site
Orientation, space, structural condition, and roof-mount versus ground-mount.
Energy consumption
Your actual daily and peak load, from a load profile — the biggest factor in sizing.
Financial feasibility
Equipment and install cost weighed against grid-connection cost and any rebates you’re eligible for.
Sizing & Cost
How we design your system — before we quote it
Off-grid sizing is fundamentally different to a grid-connect quote. Skip these steps and you end up with a battery bank that runs the generator every second night.
Load profile
You complete a load profile covering everything you’ll run, day and night, across the seasons.
Site assessment
We check solar access, roof or ground-mount options, and shading across the year.
System design
Panels, battery bank and generator sized to your load, with 3–5 days of autonomy built in.
Rebates & finance
We check what you’re eligible for against the cost of connecting to the grid instead.
Keeping It Running
Your off-grid system is your only power station — treat it like one
A monitoring device keeps you across day-to-day performance, but it’s no substitute for a professional look-over once a year — more often on dirt roads or in high-pollution areas.
Solar Integrity’s maintenance program schedules an annual clean and check (or more often, if you choose), then sends you a written report on your system’s condition and any attention it needs.
Common Questions
Off-grid solar, answered straight
What's the main difference between off-grid and grid-connected systems?
Your reliance on the utility grid. Off-grid systems generate and store all your power independently with no grid connection at all. Grid-connected systems stay connected, using solar first and drawing from the grid when needed — add a battery to that setup and it becomes a hybrid system.
Is my property suited to an off-grid system?
It comes down to four things: how much sun your site gets, whether your roof or land suits the array, how much power you actually use day to day, and whether the cost stacks up against connecting to the grid. We assess all four, free, before recommending anything. Governmnet rebates can also improve the financial case — see our rebates page for what you may be eligible for.
Will I still lose power during an outage?
Only if your battery is depleted and the auto-start generator is out of fuel, or something needs attention. Off-grid systems are your own personal power station — outages on the wider grid don’t affect you at all.
Ground-mounted or roof-mounted panels for off-grid?
Ground mounts suit rural properties with the space, or where distance from the house makes sense — though there are additional costs. Roof-mount is usually cheaper and easier to maintain, clean and expand later; most of our regional installs are roof-mount unless the site says otherwise.
Is off-grid battery storage safe?
Yes. Modern lithium batteries carry no risk of hydrogen gas emission during charging, and are the standard we recommend for new off-grid systems. Older lead-acid batteries are also safe when properly ventilated. Every system we install meets our current Clean Energy Council accreditation and safety standards. In off-grid setups, panels are typically installed on the shed roof, the battery inside the shed, and the generator beside it.
Can off-grid systems work in town, not just rural properties?
Technically yes, but it rarely makes financial sense where mains power is reliable and close by — a hybrid system usually delivers the resilience without the cost of full autonomy. Off-grid earns its keep on rural and remote properties, or specific applications like a shed, pump or outbuilding.
Are you thinking of going off-grid?
Solar Integrity has installed many hundreds of off-grid PV systems and we share our experience in this easy to follow guide. Enjoy the info and feel free to call us and ask more off-grid solar related questions.
