FindSolar.caNova Scotia rewrote its rules for home solar, and a lot of the advice floating around the province predates the rewrite. The current framework for new residential systems is Nova Scotia Power's Self-Generating Option, and it differs from classic net metering in ways that change how a smart buyer sizes a system. Here is the program as it actually stands, verified against the utility's page on August 26, 2026.
The current machinery
Under the Self-Generating Option, systems up to 27 kW sharing your home's meter offset your own consumption, and surplus kilowatt-hours are banked and applied against later bills through the calendar year. At year end, banked generation is reconciled against your billed consumption up to a maximum of what you actually consumed; generation beyond that is retired rather than purchased, because the program, in the utility's words, is not intended for customer sale of electricity. Monthly base charges continue regardless.
What the reconciliation means for sizing
The design lesson sits in that year-end rule: production up to your annual consumption is worth full value through banking, and production beyond it is worth nothing at all. Nova Scotia therefore punishes oversizing more sharply than provinces that at least pay a low rate for surplus. Size to your honest annual usage with a margin of safety below it, not above: a system at 90% of consumption wastes nothing, while a system at 115% donates its excess. The sizing guide carries the general argument; Nova Scotia supplies the sharpest version of it.
Sizing without the old rebate
The provincial homeowner rebate era is over, so the arithmetic now runs on installed cost, production and banked-credit value alone. Atlantic installed prices, your roof's orientation and your consumption profile decide payback; on planning figures Nova Scotia sits mid-pack nationally, helped by meaningful retail rates. Run the calculator on your own bill, and let quotes compete on price per watt and design quality rather than incentive theatre. Commercial properties still have a live program, listed with sources on our rebates page.
Details worth confirming for your account
Time-differentiated rate options interact with credit treatment in account-specific ways, so if your home is on one, confirm the mechanics with Nova Scotia Power before finalizing design. And every system passes through the utility's application and approval sequence before installation, the same approval-first discipline as everywhere in Canada. The program page linked above is the governing text; anything a sales deck claims that the page does not support belongs in the questions pile.
Questions homeowners ask
Is Nova Scotia still using the old net-metering program?
New residential systems operate under Nova Scotia Power's Self-Generating Option, verified on the utility's page August 26, 2026, for generators up to 27 kW sharing the home's meter. Advice and payback claims built on earlier program rules, or the old rebate, need re-checking against the current text.
What happens to electricity my panels send to the grid?
Surplus kilowatt-hours are banked and applied against your subsequent bills through the calendar year, offsetting what you draw from the grid. Base charges continue regardless. It behaves like energy credits with an annual settling-up, which is where the sizing consequences live.
What happens to unused credits at the reconciliation date?
At year end, banked generation offsets your billed consumption up to a maximum of what you actually consumed; anything beyond that is retired without payment, since the program is explicitly not a mechanism for selling power. Overproduction past your annual usage is therefore worth exactly nothing.
How large can my residential solar system be?
The Self-Generating Option covers generators up to 27 kW sharing your meter, far above typical home needs, with utility application and approval required before installation. The practical limit is not the 27 kW ceiling but your annual consumption, past which production earns nothing at reconciliation.
Does Time-of-Use billing change how my solar credits work?
Account and rate type can affect the billing mechanics, and the year-end reconciliation spans all time periods. If your home uses a time-differentiated option, confirm the interaction with Nova Scotia Power for your specific account before finalizing system design; it is a five-minute call that prevents a design-stage assumption.
How should I size solar now that the old homeowner rebate is gone?
On the current arithmetic: installed cost, your roof's production, and banked-credit value capped by your own annual consumption. Aim slightly below your usage for safety margin, compare quotes on price per watt, and run the calculator first so every claim has a benchmark waiting.
