Solar panels in Bathurst, NB

Roofs in Bathurst get about 1,419 hours of usable sunlight a year — less than 65% of the cities we've measured. Here's what that means in cost, savings and payback, using real rooftop data rather than a national average.

What a typical Bathurst solar system costs

A 23-panel system (9.2 kW) is about right for an average Bathurst home using 10,800 kWh a year. It would produce roughly 11,097 kWh annually and offset 100% of that usage.

How we worked this out for Bathurst

Every number on this page comes from these seven steps. Nothing is a national average — the sunlight figure is measured from Bathurst rooftops.

Step 6 matters more than it looks. Only 34% of what a system this size produces in Bathurst is used the moment it is generated; the other 7,317 kWh is exported and credited one-for-one under net metering. Because exports here are credited at or near retail, that split changes the payback very little — 17.6 years against the 18 we show. In places where exports pay a fraction of retail the same split moves payback by years, which is why we model it explicitly rather than assuming.

Assumptions: 400W panels, 15% system losses (inverter, wiring, heat, soiling), CA$2.85/W installed, 10,800 kWh typical annual household use, 13.4¢/kWh electricity. Change any of those and every figure above moves — which is exactly why a single national "solar costs X" number is misleading.

Notice that payback barely improves as systems get bigger, and eventually gets worse. That's because you can only save money on electricity you were going to buy anyway. Once a system covers your usage, extra panels mostly generate exports at a much lower rate.

Why Bathurst gets 1,419 sun hours

That figure comes from Google's analysis of real rooftops across Bathurst — it already accounts for shading from trees, chimneys and neighbouring buildings, which is why it's lower than the raw "hours of daylight" figures you'll see elsewhere. An unusually open, unshaded roof in Bathurst reaches about 1,420 hours, roughly 0% better than typical.

The numbers behind this page

When Bathurst actually produces

Annual totals hide the thing that catches people out: 40% of Bathurst's yearly sunlight arrives in May–July, and just 10% across November–January.

That is a severe seasonal swing — Bathurst produces roughly 4.6× as much in Jun as in Dec. A system sized to cover your annual usage will overproduce badly in summer and fall well short in winter, so how your utility credits exported power matters more here than in most places.

The annual total is measured from Google's rooftop imagery. Its split across months is calculated from solar geometry at Bathurst's latitude, not separately measured, so treat the monthly figures as the shape of a typical year rather than a forecast.

How Bathurst compares to the other 788 cities

What actually stands out about Bathurst:

• Unusually open roofs. Only 0% of available sunlight is lost to obstruction in Bathurst — better than all but 0 of the 788 cities measured. Most roofs here get close to their theoretical maximum.
• The case here is financial, not environmental. Bathurst's grid is already clean at 151 kg CO₂ per MWh, so the carbon saving from solar is modest. Judge this one on payback.
• Older imagery. Google's aerial capture of Bathurst dates from 2019. Tree growth and new construction since then are not reflected.

Cities with almost the same sunlight

These are the closest matches to Bathurst's 1,419 usable sun hours from other states and provinces. Same sunlight, different electricity prices — which is usually what decides whether solar is worth it.
