Sunnybrook Residence: 8.4 kW Solar Install in Bedford, NS

The Sunnybrook property sits in a quiet subdivision just west of the Bedford Highway, a short drive from our shop at 2 Bluewater Rd. The homeowners had lived there for eleven years and watched their winter NS Power bills climb steadily with each rate increase. Annual usage ran 12,400 kWh, with a monthly bill averaging $214 once the base charge was included.

The rear roof faces almost due south with a clean 6/12 pitch and no tree cover, which is about as good as roof orientation gets in the Halifax Regional Municipality. That geometry, combined with the household's above-average usage, pointed toward a system sized closer to the top of what the roof could hold rather than a minimal offset array.

System Specifications

• Solar panels: 20 x 420W Tier-1 monocrystalline modules with a 30-year linear performance warranty.
• Microinverters: 10 dual-module units with panel-level monitoring and shading optimization.
• Racking: anodized aluminum, CSA-certified, rated for Nova Scotia snow and wind loads.
• Monitoring: web and mobile dashboard tracking production by panel, live from day one.
• Installed by: the OYO Energy crew, start to finish. No subcontractors touched this roof.

Because Sunnybrook sits inside the Halifax Regional Municipality, the homeowners had the option to pay through Halifax Solar City, a PACE-style program that adds the loan to the property tax bill rather than the homeowner's personal credit. Financed over 10 years at a fixed rate, the monthly numbers shift, but the system still pays for itself well within its warranty period.

The cash-purchase scenario nets a few thousand dollars more over 25 years because no financing interest is paid. PACE financing costs slightly more over the long run, but it is what makes an 8.4 kW system accessible without $28,000 in cash on hand. The first ten years run modestly higher than the old NS Power-only bill would have; from year eleven onward, once the PACE balance is paid off, the household keeps producing and banking savings for another 15 years.

1. Roof orientation changed the math. A near-due-south roof with zero shading let this system produce above the typical HRM yield, which is why an 8.4 kW array reached 71% offset instead of the 60% that same size might hit on a compromised roof.
2. Sizing followed usage, not the roof's maximum capacity. The array could have gone larger, but oversizing past the household's real consumption would have created surplus credits that expire after 12 months under NS Power's net metering rules.
3. PACE financing trades a few thousand dollars for zero money down. Cash buyers keep more of the 25-year savings, but Solar City financing is what makes projects like this one realistic for homeowners who would rather not deploy $28,000 upfront.
4. The real hedge is against future rate increases. Every year NS Power's rates climb, this system's value climbs with it. The homeowners are effectively buying 25 years of electricity at today's price.
