The Town is your utility, and that changes the questions
Antigonish runs its own municipal electric utility. It serves roughly 3,000 residential and more than 500 commercial customers, and it buys its wholesale power on the open market rather than generating it. Homeowners installing solar connect through the Utility's own Solar Connectivity Form rather than through any application a Nova Scotia Power customer would use.
That distinction is easy to lose, because most Nova Scotia solar advice online is written for Nova Scotia Power customers. Those pages describe a specific set of export terms, meter arrangements and settlement dates. None of that transfers automatically to an Antigonish address, and an installer who works mainly outside the town may not realise which set of rules they are quoting under.
So treat the Utility as the first party to talk to, ahead of the roof, ahead of the equipment and ahead of the price. Ask them what the Solar Connectivity Form requires, what happens after you submit it, whether a meter change is needed, and who pays for it. Those answers determine what the rest of the project looks like.
The unpublished number: what the Utility pays for surplus
The Town does not publish export terms for customer generation. There is no public statement of what a surplus kilowatt-hour is worth in Antigonish, whether credits carry forward, or how and when they are settled. This page is not going to guess at it, and neither should an installer.
That absence is not the same as an answer in either direction. It does not mean export is refused, and it does not mean it is paid at any particular rate. It means the number is held by your utility rather than published, and the only way to obtain it is to ask. Put the request in writing so you have something to compare a quote against later.
Ask for four things specifically: what the Utility pays or credits for exported generation, whether there is any cap tied to your own annual consumption, whether credits expire or carry forward and on what date, and whether any fee applies to connect. Until you have those in hand, any payback figure in a proposal rests on an assumption someone made rather than on a term the Utility has stated. That is the single most important thing to get right about solar in Antigonish, because everything financial in the project depends on it.
Permits come from the Eastern District Planning Commission
Planning and building permits for Antigonish are not issued by the Town directly. They come from the Eastern District Planning Commission, a regional body that serves the Town alongside Antigonish, Inverness, Richmond and Victoria Counties and the Town of Port Hawkesbury.
The practical effect is a second organisation to deal with, separate from the utility. It is worth confirming with the Commission whether a rooftop or ground-mounted array needs a permit at your address, what it costs and how long review takes, rather than assuming a Town office can answer. Where two bodies are involved, the most common failure is each assuming the other has handled something.
Sequence the two. The Commission decides whether you can build the array, and the Town's utility decides on what terms it connects. Both answers should be in hand before a deposit is paid, because a project that clears one and stalls at the other is still a stalled project.
1,054 kWh per installed kW, and sizing without published terms
Natural Resources Canada's photovoltaic dataset puts Antigonish at 1,054 kWh a year for each kW of installed capacity on an unshaded, well-oriented array. A 6 kW system therefore models near 6,320 kWh a year and an 8 kW system near 8,430 kWh. That gives you an independent benchmark to test a quote's production claim against.
Sizing is harder without published export terms, and the honest way to handle that is to lean on self-consumption. Electricity your household uses as it is generated is worth what you avoid paying for it, whatever the Utility's export arrangement turns out to be. Electricity you export is worth whatever the Utility says it is worth, which you do not know yet. So until you have that answer, sizing close to your own daytime consumption is the position that does not depend on an unknown.
Expect a real roof to fall short of the benchmark and ask by how much. Midday shading costs more output than shading at either end of the day, because that is when the array should be producing hardest. An array split across two roof orientations yields less over a year than one well-oriented plane. Snow on a shallow pitch produces nothing until it clears. Ask for a model built on your address rather than a provincial average.
2,205 dwellings, and a stock shaped by the university
Antigonish has 2,205 dwellings and a population of 4,656, and its housing splits fairly evenly between ground-oriented and multi-unit living. Single-detached houses are 43.8 per cent of the stock, which is the group with an independently controlled roof and the simplest route to an install.
Low-rise apartments account for 29.9 per cent of dwellings, and individual residents of those buildings cannot add their own rooftop array: the roof belongs to the building owner. Duplexes are a further 14.3 per cent. Part of that mix is shaped by off-campus student housing near St. Francis Xavier University, which is worth knowing because it means a substantial share of the town's roofs sit above rental properties where the owner, not the occupant, makes the decision.
If you own a duplex or one half of one, the practical question is whether the roof plane you want is structurally shared, and whether the other owner needs to agree to the layout and to future maintenance access. That is a conversation to have before a design is drawn. For the 43.8 per cent in single-detached houses, none of this applies and the roof is simply yours.
Heritage registration, and what is left on the incentive list
Antigonish has no heritage conservation district, so there is no area-wide overlay applying to a whole neighbourhood. Instead, Council can register individual buildings, streetscapes or areas in the Municipal Registry of Heritage Property under the Town's Heritage Property By-law, and the Town publishes a list of currently registered properties. Because registration is property by property, the only reliable check is against your own address rather than your street.
On money, the first thing to know is a closure. Efficiency Nova Scotia's SolarHomes rebate stopped taking new applications on April 17, 2025. If a quote still shows a SolarHomes deduction, it is priced on a programme that no longer accepts applicants.
The provincial record also lists PACE financing in participating municipalities, which attaches the cost of an energy retrofit to the property tax bill rather than requiring cash upfront, so ask the Town whether Antigonish participates. The federal Clean Technology investment tax credit is not part of that picture: the Income Tax Act limits it to taxable Canadian corporations and certain trusts, so an individual cannot claim it. That credit is claimed against a qualifying investment by an eligible claimant, so ask an accountant whether a household purchase qualifies before it goes into a payback figure. Note too that whether a battery makes sense here depends on the export terms you still need to obtain from the Utility, since the value of storing power rather than exporting it turns entirely on what exporting pays.
