Short answer: no. In Alberta, a home battery is almost never the best use of the next $15,000 you spend on your solar project — and if you are on the right electricity plan, the grid already does the job a battery would do, and pays you better for it.
This is one of the most common questions we get from Albertans who are part-way through a solar quote. A salesperson adds a battery line item, the price jumps by $12,000 to $20,000, and the pitch is “energy independence.” Before you sign, it is worth understanding how micro-generation actually works in this province, because Alberta’s rules make batteries far less necessary here than in places like California or Australia.
How Alberta already gives you a “battery” for free
Under Alberta’s Micro-generation Regulation, a residential solar system under 150 kW is credited for every kilowatt-hour it sends to the grid. You do not need to consume your solar production the moment it is generated. Your bi-directional meter tracks what you export, and your retailer credits you for it.
Functionally, that means the grid is acting as your storage. You export surplus power on a sunny July afternoon, and you draw power back on a dark January evening. There is no round-trip efficiency loss, no equipment to replace in 10–15 years, and no upfront cost — the wire service provider installs the bi-directional meter as part of the interconnection.
A physical battery only adds value if it earns more than the grid does for those same kilowatt-hours. In Alberta, that is a very hard bar to clear, and here is why.
The Solar Club math: your exports are worth 35¢/kWh
What a battery saves you is the difference between what you get paid for exporting a kilowatt-hour and what it costs you to buy one back later. In most jurisdictions, export credits are low and retail rates are high, so storing your own power beats selling it. Alberta with the right retailer works the opposite way.
On Get Energy’s Solar Club, you choose between two rates and can switch with 10 days’ notice:
- HI rate — 35.00¢/kWh. Used in your export-heavy months (roughly April through September). Every surplus kilowatt-hour your roof sends to the grid is credited at 35¢.
- LO rate — 5.90¢/kWh. Used in your import-heavy months (roughly November through February), so the power you buy back in the dark months is cheap.
That combination is the whole argument against a battery. You are selling summer surplus at 35¢ and buying winter power back at 5.90¢ — a spread of roughly 29¢ per kilowatt-hour in your favour. A battery cannot beat that, because a battery’s best case is avoiding a purchase at the import rate. Storing a kilowatt-hour to avoid buying it at 5.90¢ means giving up 35¢ of export credit for it.
Put plainly: on the Solar Club, every kilowatt-hour a battery holds back from the grid in the summer costs you money.
A worked example — 8 kW system, typical Alberta home
Take an 8 kW system on a south-facing roof, producing roughly 10,400 kWh a year. Assume about 4,000 kWh of that is exported during the April–September window rather than consumed on the spot.
| Scenario | What happens to 4,000 kWh of summer surplus | Annual value |
|---|---|---|
| No battery, Solar Club HI rate | Exported to the grid at 35.00¢/kWh | $1,400 in credits |
| Battery installed | Stored, then used at home to avoid buying power at the LO rate of 5.90¢/kWh | $236 in avoided cost |
The no-battery scenario is worth roughly $1,164 more per year — and that is before you account for the battery’s purchase price, its efficiency losses (typically 10–15% round trip), and the fact that most home batteries are warrantied for 10 years while your panels are warrantied for 25.
Add a $15,000 battery on top and it does not pay back within its own warranty period. It never breaks even.
The one thing a battery genuinely does buy you: outage protection
We are not going to pretend batteries are useless. There is one real benefit, and it has nothing to do with economics: backup power during an outage.
This is worth understanding clearly, because it surprises people. A grid-tied solar system without a battery shuts down during a power outage. Your inverter is required to disconnect for the safety of line crews (anti-islanding). So if your reason for wanting solar is “the power goes out on my road six times a winter,” panels alone will not solve that — and that is a legitimate reason to consider storage or a generator.
If outage resilience is the goal, compare honestly:
| Option | Typical cost | What it covers |
|---|---|---|
| Home battery with backup capability | $12,000–$20,000+ | Silent, automatic, runs essential circuits for hours to a day; recharges from solar |
| Portable inverter generator | $1,000–$2,500 | Fridge, furnace fan, a few outlets; needs fuel and manual setup |
| Standby natural gas generator | $6,000–$12,000 installed | Whole-home, automatic, unlimited runtime on the gas line |
For most Alberta homes in a city with reliable distribution, none of these are necessary. For an acreage at the end of a long rural feeder, a standby generator usually delivers more outage protection per dollar than a battery does. Choose storage because you want resilience and have decided it is worth paying for — not because someone told you it would save you money.
Where a battery does start to make sense in Alberta
There are narrower cases where storage earns its keep:
- You are off-grid or effectively off-grid. No interconnection means no grid battery. Storage is mandatory, not optional.
- You run a business that cannot go dark. Server rooms, commercial refrigeration, livestock ventilation, medical equipment at home. Here the cost of an outage is measured in spoiled inventory or worse, and the math changes completely.
- You are on the wrong electricity plan and cannot switch. If your retailer credits exports at 8¢ instead of 35¢, storage looks much better by comparison. Note the cheaper fix: change retailers.
- You have a commercial or farm operation that can claim the 30% Clean Technology Investment Tax Credit. Battery storage installed with solar is eligible equipment for corporations, which materially improves the payback. This does not apply to residential homeowners.
What to do with the money instead
If you have $15,000 of headroom in your solar budget, here is where it does more work than a battery, in order:
- Buy more panels. Alberta’s Micro-generation Regulation allows you to size a system to your annual consumption (installers typically design to roughly 110% with documented usage). If your quote is smaller than your consumption allows, extra capacity earns 35¢ on every exported kilowatt-hour for 25+ years. Nothing else in the project has that return.
- Get on the right rate plan. Free. Switching to a plan that pays 35¢ on exports rather than a flat retail rate is typically worth over $1,000 a year on an 8 kW system — see our Solar Club breakdown.
- Fix the roof first. If your shingles have under 10 years left, re-roof before the array goes up. Removing and reinstalling panels later costs thousands.
- Electrify a load you currently pay gas or gasoline for. A heat pump or EV charging turns your cheap self-generated power into a much bigger monthly saving. See our guides on heat pumps in Alberta and home EV charging.
The honest summary
Alberta is one of the few places in North America where a homeowner can be paid 35¢/kWh for exported solar power while buying it back at under 6¢. That spread makes the grid a better battery than a battery — cheaper, longer-lasting, and with no replacement cycle.
Buy storage if you want your lights to stay on during an outage and you have priced the alternatives. Do not buy it as an investment. And before you spend anything, make sure you are on a plan that actually pays you properly for what your roof produces.

Frequently Asked Questions
Do I need a battery for solar panels in Alberta?
No. Alberta’s Micro-generation Regulation lets your solar system export surplus power to the grid for bill credits, so the grid performs the storage function a battery would. On a plan like the Solar Club, exports are credited at 35.00¢/kWh, which is far more than a battery can save you by storing the same power.
Will my solar panels work during a power outage without a battery?
No. Grid-tied inverters are required to shut down during an outage to protect utility line workers. If you need power during outages, you need a battery with backup capability or a generator — panels alone will not do it.
How much does a home battery cost in Alberta?
Most residential battery systems run $12,000 to $20,000 or more installed, depending on capacity and whether backup circuits are wired in. Batteries are typically warrantied for about 10 years, compared with 25 years for solar panels.
Is it better to export solar power or store it in Alberta?
Export it, in nearly every residential case. On the Solar Club HI rate you receive 35.00¢/kWh for exported power, while storing that power only avoids buying it back at the LO rate of 5.90¢/kWh. Exporting is worth roughly 29¢ more per kilowatt-hour.
Can I add a battery later if I change my mind?
Yes. Batteries can be retrofitted to most existing solar installations, though AC-coupled retrofits cost somewhat more than installing storage at the same time as the panels. Since the economics rarely favour storage in Alberta, waiting costs you very little and lets battery prices keep falling.
Do batteries help with Alberta’s winter solar production?
Not meaningfully. A battery shifts power by hours, not by months. Alberta’s winter shortfall is seasonal — a December problem solved by summer surplus — and only the grid can shift energy across that kind of timespan. That is exactly what micro-generation credits do.
