If you've been looking at GloBird's ZeroHero and wondering what else is out there, you're doing the sensible thing. No single energy plan is right for every home, and the only way to know if one suits you is to line it up against the alternatives on the same terms. That's what this guide is for: not to tell you one plan is best, but to give you the questions that actually separate a good fit from a poor one.
A quick, honest caveat before we start. Energy plan details, rates, structures and conditions change often, and they vary by state and by household. So rather than quote figures that could be out of date by the time you read them, this guide focuses on how to compare any solar or energy plan properly, using ZeroHero as the starting point you already know. Always confirm the current terms of any plan directly with the provider before deciding.
This guide covers what to look at in ZeroHero, the criteria that matter when comparing plans, the kinds of alternatives worth weighing, and how to land on the right one for your home.
What GloBird ZeroHero Offers (Quick Overview)
GloBird Energy is an Australian electricity retailer, and ZeroHero is one of its energy plans. Like any retail plan, its value to you depends on your usage pattern, your state, and the specific rates and conditions in place when you sign up. Those specifics are exactly the things to read carefully rather than take from a headline.
Because plan structures shift over time, the fair approach is to treat whatever's currently advertised as your reference point and then ask: what am I actually getting, on what terms, and how does that compare to other ways of powering my home? That includes not just retail electricity plans but solar and battery arrangements, which change the equation entirely.
The useful move isn't "is ZeroHero good or bad." It's "what does a genuinely good plan look like for a home like mine," and then measuring every option, including ZeroHero, against that.
What to Compare When Choosing a Solar Plan
Four things do most of the work when you're comparing plans. Get clear on these and the noise falls away.
First, the rate, and whether it's fixed or variable. A rate that's low today but free to rise leaves you exposed to future price increases; a genuinely fixed rate locks in your cost. Read which one you're actually getting.
Second, what's included. Is this just a retail electricity rate, or does it include solar and battery hardware? A plan that puts a system on your roof is a fundamentally different proposition from a plan that just prices the grid power you buy.
Third, the battery, if there is one. Its size in kWh decides how much of your evening you run on stored solar versus grid power. A small battery empties before morning; a larger one carries the night.
Fourth, the contract: how long is the term, what happens if you move, and what are your exit or buy-out options? Ask yourself, would this plan still suit me if my circumstances changed in a few years?
Alternatives to Consider in 2026
Broadly, your options fall into a few camps. There are straight retail electricity plans, where you're just buying grid power at some rate, ZeroHero sits in this world. There are buy-your-own solar and battery setups, where you own the hardware and carry the cost and risk. And there are energy-as-a-service or PPA-style plans, where a provider installs and owns solar and a battery, and you pay a fixed rate for the power with no upfront cost.
Each suits a different priority. A retail plan is simplest but leaves you fully exposed to grid prices and gives you no solar of your own. Buying gives you ownership but a big upfront bill and all the risk. An EaaS plan gives you solar and storage without the outlay, at a fixed rate, in exchange for not owning the hardware.
Which camp fits you depends on whether you want the lowest-commitment option, full ownership, or predictable clean power without the capital cost. Naming your priority first makes the comparison much easier.
How to Pick What's Right for Your Home
Start with your evening. When do you use the most power, and how much of your bill comes from after-dark grid electricity? If that number is large, a plan with a properly sized battery will do more for you than a sharper daytime rate. If you're barely home in the evening, the calculus shifts.
Then weigh certainty against flexibility. A fixed rate protects you from price rises but ties you to a term; a variable retail plan is more flexible but exposes you to increases. Neither is automatically better, it depends on how much you value predictable bills.
Picture opening two plans side by side: one a bare electricity rate that could move next quarter, the other a fixed rate that also puts solar and a battery on your roof. They're not really competing on the same thing, are they? That's the insight, comparing plans means comparing what you actually get, not just the number on the front.
A Real-Life Scenario: Comparing Like With Like
Picture a homeowner who'd shortlisted ZeroHero and a couple of other options and felt stuck, because the plans didn't line up neatly. One was a retail rate, one was buy-your-own solar, one was a fixed-rate plan with a battery included. On price alone, they looked wildly different, and none of the comparisons felt fair.
The breakthrough came when she stopped comparing headline numbers and started comparing outcomes: how much would I actually pay across a year, how exposed am I to price rises, how much of my evening runs on my own power, and what happens if I move? Reframed that way, the "cheapest" headline wasn't the best deal for her home at all. The plan that gave her a fixed rate and covered her evenings won, not because it looked cheapest, but because it fit.
Where Tesseract ZERO Fits In
If what drew you to ZeroHero was the promise of lower, simpler energy costs, Tesseract ZERO is worth putting on your shortlist as an EaaS-style alternative. It installs a 6.6kWp solar and 20kWh battery system with $0 upfront and $0 maintenance, and you pay a fixed $0.28/kWh for the power through the Tesseract retail partner. The fixed rate means you're not exposed to grid price rises, the 20kWh battery is sized to carry a full household evening where many plans stop at 10 to 13kWh, and because Tesseract owns the hardware, the inverter and maintenance risk isn't yours. Whether it's the right fit still comes down to your own usage, which is exactly why it's worth comparing directly rather than on a headline.
The Bottom Line
Finding the right GloBird ZeroHero alternative isn't about crowning one plan the winner, it's about comparing options on the things that actually matter: whether the rate is fixed or variable, what's included, the battery size, and the contract terms. Because plan details change often, confirm the current terms of anything directly with the provider. Then judge each option by outcomes for your home, your annual cost, your exposure to price rises, how much of your evening you cover, and your flexibility, rather than by the headline number. The best plan is the one that fits your usage, not the one that looks cheapest at a glance.

Frequently Asked Questions
What should I look for in a GloBird ZeroHero alternative?
Compare on four things: whether the rate is fixed or variable, what's actually included (just grid power, or solar and a battery too), the battery size in kWh, and the contract terms including exit options. Judge each plan by your annual cost and how much of your evening it covers, not just the headline rate.
Is a fixed-rate energy plan better than a variable one?
A fixed rate protects you from grid price rises and makes budgeting easier, but ties you to a term. A variable rate is more flexible but exposes you to increases. Which is better depends on how much you value predictable bills versus flexibility. Always check current terms directly, as these change often.
How do I compare solar plans fairly?
Compare outcomes, not headlines: your total expected cost across a year, your exposure to future price rises, how much of your evening power comes from your own system, and what happens if you move or want to exit. Plans structured differently, retail, buy-your-own, or EaaS, only compare fairly when you look at what you actually get.
