How much does it cost to add solar panels during a renovation in NB?

Solar panel installation during a renovation in New Brunswick typically costs $15,000-$30,000 for a residential system, with the renovation timing offering potential savings on electrical upgrades and roof work.

Adding solar panels during an active renovation can be more cost-effective than a standalone installation since you're already coordinating electrical work and potentially roof modifications. A typical NB home solar system ranges from 5-10 kW capacity, costing $2.50-$3.50 per watt installed. This means a 6 kW system (suitable for most NB homes) runs $15,000-$21,000, while a larger 8-10 kW system costs $20,000-$35,000. These prices reflect the federal solar rebate programs but note that NB currently has limited provincial solar incentives compared to other Maritime provinces.

The renovation timing advantage comes from shared electrical work costs. Solar installations require electrical panel upgrades in many older NB homes — if you're already upgrading your electrical panel for a kitchen renovation or whole-home project, adding the solar-ready components costs only an additional $500-$1,500 versus $2,000-$4,000 for a standalone electrical upgrade. Similarly, if you're re-roofing during your renovation, installing solar mounting hardware during the roofing process costs significantly less than retrofitting later.

NB's climate presents both opportunities and challenges for solar. While winter snow reduces solar production, NB receives excellent summer solar exposure, and solar panels actually perform more efficiently in cooler temperatures. The key consideration is snow load management — NB's 200+ cm annual snowfall means solar installations must account for significant roof loading. Your structural engineer should verify that your roof can handle both the panel weight and increased snow retention that panels create. Ice damming can also be affected by solar panel placement, so proper roof ventilation and ice-and-water shield installation become even more critical.

Net metering in NB allows you to sell excess solar production back to NB Power at retail rates, making properly sized systems financially viable. However, NB Power's net metering program has capacity limits and interconnection requirements that must be navigated during the permit process. The electrical work requires a licensed TSANB electrician, and the system must pass both municipal building inspection and NB Power interconnection approval.

Timing considerations are crucial for renovation-integrated solar. Solar panel installation should happen after roofing completion but before final electrical inspection. If you're doing exterior work, coordinate solar installation with siding, soffit, and trim work to ensure clean cable routing and proper weatherproofing. Winter installation is possible but more expensive due to weather delays and snow removal requirements.

When to hire professionals: Solar installation requires licensed electrical work (TSANB jurisdiction), structural engineering assessment for roof loading, and coordination with NB Power for interconnection. This is definitely professional-only work. Get quotes from solar installers experienced with NB's climate conditions and net metering requirements.
