Solar Equipment We Use in Nova Scotia
Tier-1 panels, microinverters, racking, and monitoring systems used by our installer partners across NS. Tested through Atlantic weather and backed by some of the strongest warranties in the industry.
What Goes On Your Roof (and What Doesn't)
A residential solar PV system has four main components plus the electrical interface to your home. Below is exactly what we specify by default, why we specify it, and what the warranties cover. Equipment selections may vary slightly by installer partner based on availability and project-specific requirements, but the baseline standards never drop below what is documented here.
Tier-1 Monocrystalline Modules
Solar panels are the heart of the system. Tier-1 designation refers to the manufacturer's financial strength, manufacturing scale, and bankability, not just the cells. Tier-1 panels carry the longest warranties because the manufacturer is statistically likely to still exist 25 to 30 years from now to honour them.
Common Panel Specifications We Use
- LONGi LR7-54HGBB 440W — 144-cell monocrystalline, P-type cell technology, low-irradiance optimization, zero LID (light-induced degradation), AAA solar brand rating
- LONGi LR8-54HGBB-500W — Newer 500W generation for larger residential installs, slightly higher efficiency per module footprint
- Canadian Solar HiKu / TopBiHiKu — Alternative Tier-1 brand often used in commercial projects
- Trina Vertex series — Alternative when LONGi inventory is constrained
What the 30-Year Warranty Means
Modern Tier-1 panels carry a linear performance warranty: the manufacturer guarantees the panels will produce a minimum percentage of their nameplate capacity at every year. A typical structure is 98% at year 1, declining linearly to roughly 87% at year 30. If a panel falls below that line, the manufacturer replaces it. In practice, real-world degradation is usually slower than the warranty curve, meaning most panels exceed warranted production for their full life.
Why Mono Beats Poly
Monocrystalline panels achieve higher efficiency (typically 20 to 22%) than older polycrystalline panels (15 to 17%). For a given roof area, this means more wattage installed and more annual production. Modern Tier-1 residential panels are virtually all monocrystalline.
Built for Canadian Conditions
- Hail and snow load tested: Modules certified for 5400 Pa snow load and 1 inch hail at 50 mph
- Low irradiance performance: Strong output on cloudy days, which matter on the South Shore and Cape Breton
- Salt-fog certified: Marine-grade certification for coastal NS installations
- Cold-weather coefficient: Modules actually produce more efficiently in cold weather, an advantage in Atlantic Canada
Microinverters Over String Inverters
The inverter converts the DC electricity from the panels to AC electricity for your home and the grid. The choice between microinverters (one per panel pair) versus a single central string inverter is one of the most important decisions in your system design.
Why We Default to Microinverters
- Module-level monitoring: See production from each panel individually in the mobile app. Identifies issues immediately rather than after weeks of underperformance.
- Shading tolerance: One shaded panel does not drag down the rest of the array. Each panel operates at its individual maximum.
- No high-voltage DC on the roof: Each microinverter outputs 240V AC, avoiding the arc-fault and fire risks of high-voltage DC strings.
- Easier expansion: Adding panels later just means adding more microinverters. With a central string inverter, you may need to replace the inverter to accommodate more capacity.
- Longer warranty: Microinverters typically carry 20 to 25-year warranties versus 10 to 12 years for string inverters.
Common Microinverter Models
- Enphase IQ8 series — 97% efficiency, grid-forming capability for future battery integration, 25-year warranty, the industry gold standard
- Hoymiles HMS series (HMS-1800, HMS-900, HMS-500) — Dual-module and quad-module options, 97.5% efficiency, 20-year warranty, often used to balance cost and performance
- APsystems DS3 / QS1 — Alternative high-efficiency option, 25-year warranty
When a String Inverter Makes Sense
For larger commercial projects (50 kW+), a single string inverter or several centralized inverters often makes economic sense because the panel-level monitoring benefit shrinks relative to the cost savings. For residential, microinverters are nearly always the right call.
Anodized Aluminum, CSA Certified
Racking is the unsexy part of solar that ends up mattering enormously over a 25-year system life. Cheap racking that rusts, warps, or fails its anchoring is the most common cause of premature solar system retirement. We specify CSA-certified, anti-rust treated, anodized aluminum racking that has been tested across thousands of Canadian roofs.
What Quality Racking Looks Like
- Material: Anodized aluminum rails with stainless steel mounting hardware. No mild steel, no galvanized-only finishes.
- Roof penetrations: Properly flashed with EPDM gaskets or aluminum flashings, never relying on caulk alone. Should outlast the panels.
- Engineering: Structural design reviewed by a Professional Engineer (P.Eng.) for snow and wind loading specific to your region.
- Wind load rating: Engineered for Atlantic exposure category, typically rated for 130+ km/h sustained winds.
- Critter guards: Wire mesh around the array perimeter to prevent rodents and birds from nesting underneath. Included as complimentary on most installs.
- Grounding: Properly bonded electrical ground per Canadian Electrical Code.
Roof Types We Mount On
- Asphalt shingle: Most common in NS residential. Standard rail-mount with flashed mounting feet.
- Metal roof: Specialized clamps that attach without penetrations on standing-seam, or with sealed fasteners on screw-down profiles.
- Cedar shake: Requires specialized flashing details. Some shake roofs are not viable for solar without replacement.
- Flat / low-slope: Ballasted or anchored tilt-racks set at optimal angle for the latitude.
- Ground-mount: Foundation-anchored steel posts with aluminum racking, optimal tilt and orientation, no roof needed.
What You See and What Keeps You Safe
Modern solar systems include continuous monitoring and a suite of electrical safety devices that protect both your home and the NS Power technicians working on the grid. Most homeowners interact with the monitoring app daily for the first few months, then occasionally for system check-ins.
Monitoring System
- Gateway / monitoring hub: Communicates with each microinverter and uploads production data to the cloud
- Mobile app: iOS and Android apps showing real-time production, daily/monthly/yearly totals, individual panel performance, and grid status
- Web dashboard: Same data accessible via web browser for desktop review
- Remote troubleshooting: Your installer can diagnose issues remotely via the same monitoring platform
- Production alerts: Email or push notifications if any panel underperforms or the system goes offline
Electrical Safety Devices
- AC Disconnect Switch: Lockable disconnect installed near the main electrical panel. Required by code so NS Power technicians can de-energize the system during grid maintenance.
- DC Disconnect (where applicable): For systems with central inverters; not needed with microinverters since each module's DC is contained at the panel.
- Rapid Shutdown: Mandatory for residential rooftop solar per NEC/Canadian Electrical Code. Microinverters provide this natively.
- Grounding system: Equipment grounding conductor bonded to your home's grounding electrode system.
- Surge protection: SPDs (surge protective devices) on both AC and DC sides protect against lightning and grid surges.
- Code-compliant labeling: Yellow placards identifying the solar system at the meter, main panel, and AC disconnect locations.
The NS Power Bi-Directional Meter
After commissioning, NS Power swaps your existing meter for a bi-directional meter that measures both consumption and export. This is what makes net metering work. The meter swap takes roughly 30 minutes and causes a brief power interruption. No charge for the swap.
Pairing Storage with Solar
For homeowners adding battery storage either at install or as a future retrofit, here are the systems we recommend for NS conditions:
Recommended Battery Systems
- Tesla Powerwall 3 — 13.5 kWh capacity, 11.5 kW continuous output, integrated solar inverter (DC-coupled), whole-home backup capable, 10-year warranty. Most popular for new solar+battery installs.
- Enphase IQ Battery 10 / 5P — Modular 5 or 10 kWh units, AC-coupled, native integration with Enphase microinverter solar systems, 10 to 15-year warranty.
- Franklin Home Power — 13.6 kWh capacity, exceptional cold-weather performance, popular for rural NS where temperatures swing widely.
- Generac PWRcell — Modular 9 to 36 kWh, integrated transfer switch, generator-replacement style installs.
What Battery Storage Adds
- Storm backup: Run essentials for 12 to 72 hours during NS Power outages, indefinitely when paired with solar that recharges during daylight
- Solar self-consumption: Store midday surplus to power evening loads rather than export to the grid
- Future TOU rate readiness: If NS Power introduces residential time-of-use rates, batteries enable arbitrage
- Whole-home or critical-loads: Choose between backing up the whole house or just essential circuits
Why Equipment Alone Is Not Enough
Two homes can use identical Tier-1 panels and end up with very different long-term outcomes based on installation quality. Roof penetration sealing, electrical workmanship, microinverter cable management, and grounding integrity all matter as much as the components themselves. This is why we are deliberate about installer selection.
Installer Standards We Require
- Licensed electrician on site for all electrical work (Nova Scotia Master Electrician or Journeyman)
- Manufacturer-trained personnel for panel and inverter installation (Enphase Certified Installer, LONGi authorized installer, etc.)
- Workers Compensation Board coverage and full liability insurance
- P.Eng. structural review for systems over 10 kW or any system on a non-standard roof
- 10-year workmanship warranty on labour and roof penetrations
- Documented installation procedures following CSA and Canadian Electrical Code standards
