A fee you can calculate, and an exemption to check
Bridgewater requires a Building Permit for structural work, additions and renovations, and it charges by construction value: $3 per $1,000, with a $25 minimum for projects under $8,500. That is a transparent structure, because it lets a homeowner arrive at an approximate permit cost from the quote alone rather than waiting to be told.
There is also an exemption, and it is the part worth asking about. Non-structural exterior alterations valued at $5,000 or less do not require a permit. Solar is not named as its own category in the town's description, so whether a given array counts as structural work or as a non-structural exterior alteration is genuinely a question for the town rather than a matter of interpretation by an installer. Most complete rooftop systems will exceed the $5,000 exemption threshold on value alone, but the structural question is separate from the value question and both matter.
Ask the town with your actual quoted construction value in hand. That way the answer covers your project rather than a hypothetical one, and you learn whether a permit is required, what it will cost under the per-thousand formula and how the town classifies the work. All three are worth knowing before a crew is scheduled.
A statutory right up to 27 kW, with nothing to pay
Residential solar in Nova Scotia connects under a self-generation option written into the Electricity Act by the Bill 145 amendments in April 2022, covering systems up to 27 kW. The reason to care about the wording is stability. A utility programme can be closed to new applicants or repriced by the utility that runs it. A right set out in statute is changed by the legislature instead.
The mechanics involve almost nothing on your side. There is no separate net metering application, no sign-up fee, and the bidirectional meter is installed at no cost. A licensed installer submits plans to Nova Scotia Power, the meter is swapped where needed, and surplus generation begins banking as a bill credit.
Do not go looking for Nova Scotia Power's net metering programme, and be wary of an installer who does. That programme now carries a 27 kWac minimum, which is above the residential ceiling, so a Bridgewater house never falls under it. Rates for Nova Scotia Power are approved through the Nova Scotia Energy Board, and the residential default is a flat Domestic Service Tariff with no mandatory time-of-use pricing.
1,080 kWh per kW, and why annual usage sets the size
Natural Resources Canada's photovoltaic dataset gives Bridgewater 1,080 kWh a year for each kW of installed capacity on an unshaded, well-oriented array. That makes a quote easy to translate: a 6 kW system models near 6,480 kWh a year, a 9 kW system near 9,720 kWh. Use those figures to compare proposals, not to decide how big to go.
The sizing decision comes from the export terms. Surplus is purchased at a rate equivalent to the rate you pay, 19.128 cents per kWh on the residential tariff effective May 1, 2026, up to a maximum of your total usage per calendar year. Above that annual total there is no compensation at all. So the binding number is the yearly kWh figure on your own Nova Scotia Power bills, and an array modelled to beat it is producing electricity that earns nothing.
Credits are banked and settled each January 1, which is the right rhythm for this climate: high-output summer months carry forward into low-output winter ones instead of expiring monthly. Assume a real Bridgewater roof lands under the benchmark and ask why. Midday shade from a mature tree costs more than shade at either end of the day, a two-plane array yields less annually than a single well-oriented plane, and snow on a shallow slope produces nothing until it clears.
Just under half houses, close to a third low-rise
Bridgewater has roughly 4,260 dwellings and about 48 per cent of them are single-detached houses with an independently controlled roof. That is the group for whom this is a straightforward decision: the permit question and the physical roof are the only things standing in the way.
Close to 30 per cent of the stock is low-rise apartments and condominiums under five storeys, where rooftop solar depends on landlord or condominium board approval. A small high-rise share of 0.8 per cent adds a handful more buildings in the same position. If you rent or own a unit rather than a building, the first step is establishing who controls the roof and whether they are interested, which is a different conversation from getting a quote.
Shared-roof homes are a modest slice: semi-detached at 5 per cent, duplexes at 2.8 per cent and row houses at 2.2 per cent. For those, the question is where your roof plane actually ends. In a town of 8,790 people the majority of solar projects will be single-detached houses, but the multi-unit share is large enough that a meaningful number of Bridgewater residents will need someone else's agreement before anything else can happen.
SolarHomes has closed: what that means for your quote
Efficiency Nova Scotia's SolarHomes rebate stopped accepting new applications on April 17, 2025 and is now closed. The practical consequence is about comparing prices. Two Bridgewater quotes are not comparable if one still nets off a SolarHomes amount and the other does not, and the one that does is assuming a programme that no longer takes applicants.
PACE financing is on the provincial record and is a different kind of thing. It attaches the cost of an energy retrofit to the property tax bill instead of requiring cash upfront, in participating municipalities, so ask the town whether Bridgewater participates rather than reading the province-wide listing as an answer for your address. It moves when you pay, not how much.
The federal Clean Technology investment tax credit, often quoted at homeowners, is confined by the Income Tax Act to taxable Canadian corporations and certain trusts, so it is not one you can claim. Since an investment tax credit is claimed against a qualifying investment by an eligible claimant, put the question of whether it reaches a household rooftop purchase to an accountant before building it into a payback figure. And on storage: because Nova Scotia buys surplus at your own retail rate up to your annual use, the case for a battery in Bridgewater is backup power during an outage rather than capturing a price spread.
