Solar installation Cochrane homeowners choose starts with a site visit, not a sales pitch. We design grid-tied systems in the 8 to 12 kW range for most homes we see here, with 10 kW being the size we land on most often once we've looked at a property's roof and usage pattern. Every system we install uses LONGi panels paired with APsystems microinverters. APsystems microinverters are optimizers, each one tied to a single panel rather than one central inverter handling the whole array; that means if one panel ends up in shade from a tree or a neighboring roofline for part of the day, it doesn't drag down the output of the rest of the string. The housing stock here runs the gamut from older infill near Historic Downtown Cochrane to newer two-story builds on the west side, and roof geometry varies accordingly. Some homes have a single clean south-facing slope that makes for straightforward mounting. Others have hips, dormers, or a garage roofline that competes with the house for the best sun exposure, and those need a more careful layout to get full value out of each panel. We account for all of that before we quote a system, not after. Installation itself covers racking, panel mounting, wiring to the microinverters, and connecting the system to the home's electrical panel. We handle the design engineering and the FortisAlberta interconnection application as part of the project, so homeowners aren't left figuring out utility paperwork on their own.
Solar Planning for Cochrane Properties
Cochrane's growth tells you a lot about what we're sizing for here. The 2021 census put the population at 32,199, up from 25,853 the census before, and that kind of growth means more new builds, more garages, and more properties where the electrical panel was sized for a smaller home than what's standing on the lot today. The town itself goes back further than most of its subdivisions: founded in 1881, incorporated as a village in 1903, and as a town in 1971, with Cochrane Ranche Historic Site still marking where that history started. The area sits as a town in Alberta within the Calgary Metropolitan Region, close enough to Calgary's grid infrastructure that most properties here are on standard residential service, but spread out enough that lot sizes and roof layouts vary more than a typical city block. We don't start a design with assumptions about any of that. We start with the property: roof pitch and orientation, what's shading it, the condition of the panel, and what the most recent power bill shows about how the home actually uses power month to month. That's the only way to land on a system that fits a town of over 32,000 people where some streets are decades old and others went in last spring.
Electrical Site Review for Local Properties
Voltage Rise
Voltage rise happens when the voltage at a property measures higher than standard at the point a solar system feeds power back into the home's wiring, and it tends to show up more on homes farther from a distribution transformer or at the end of a longer line run. We check for it during the site visit because it affects how a microinverter responds under load. If voltage rise is a concern on a given property, it factors into how we size the system and select equipment to keep inverters operating inside their normal range rather than clipping output.
Single-Phase vs Three-Phase
Properties in this area can have either single-phase or three-phase electrical service, and which one a property has changes what inverter setup makes sense. Single-phase service is standard on most residential properties and works fine with APsystems microinverters sized for that service. Three-phase service, more common on larger properties or those with heavier shop or outbuilding loads, needs equipment and a system design that matches that service type, so we confirm which one a property has before finalizing a design.
Panel Infrastructure
Older electrical panels, especially on properties built well before today's higher-draw appliances and EV chargers became common, sometimes don't have the breaker capacity to add a solar interconnection without changes. We check the panel's age, its rated capacity, and how much room is left on the bus for a new breaker. If the panel can't support the added system, an upgrade means replacing or augmenting the panel before the solar installation can be finished.
Service Entrance Review
We review the service entrance and meter base as part of every site visit, checking the condition of the wiring, the meter base enclosure, and the physical connection point. That condition matters because FortisAlberta's micro-generation application requires the service entrance to meet their current standards before they'll approve the interconnection. When an upgrade is needed, we identify it during the site review so it's part of the project plan from the start, not a surprise mid-installation.
Right-Sizing Solar for Rural and In-Town Properties
Rural and semi-rural Alberta properties typically need bigger systems than a comparable house in the middle of a city, and that's usually because there's more than one load to cover. A property might be running the house plus a detached garage, a workshop, or outbuildings, and each of those adds to the load a system has to offset. We size for all of it, not just the main panel. Roof versus ground mount is a real decision, not a default. A roof mount makes sense when the roof has decent pitch, a clear south or west-facing slope, and isn't shaded by mature trees or a neighboring structure. Ground mount becomes the better call when a roof is heavily shaded, the pitch or orientation works against the system, or when a property simply has open yard space that makes a ground-mounted array easier to access for maintenance and easier to size to the right capacity without compromise. Either way, we size the system from the 12-month usage graph on your most recent power bill, which shows how the property's usage moves across the year, rather than from a rule-of-thumb number like "most homes need X kW." That graph, combined with a site visit and the roof or ground-mount conditions we find, is what actually tells us the right system size for a specific property, not a generic estimate.
Typical Load Profiles We Design For
Home Plus Attached Garage
This is the most common profile we see close by: a single-family home with an attached or detached garage, sometimes with a second fridge or freezer out there, or a bit of winter heating for the space. We use the most recent power bill and a site visit to see how that garage load shows up across the year before we size anything.
Home Plus Heated Shop
Properties with a heated workshop or hobby shop separate from the house carry a different load pattern, especially if there's woodworking equipment, welding gear, or vehicle lifts running in there. That shop load can shift the right system size up from what the house alone would need, which is why we look at the full picture on the power bill rather than sizing off the house in isolation.
Home Plus Secondary Suite or Rental
Some properties around here include a secondary suite, a basement rental, or a carriage house with its own appliances and heating draw. When a property has a second living space pulling power on the same meter, we factor that combined usage into the system size rather than assuming one household's worth of draw, using the usage graph on the most recent bill to see how it actually plays out.
FortisAlberta Interconnection in Cochrane
FortisAlberta is the wire service for Cochrane, and any grid-tied solar system here has to go through FortisAlberta's micro-generation interconnection process before it can be switched on. That application covers the technical details of the system, including panel and microinverter specifications, single-line diagrams, and the point of connection at the home's service entrance. We prepare and submit that application as part of every project here. That means pulling together the equipment specifications for the LONGi panels and APsystems microinverters, confirming the home's service entrance can support the new load, and handling the back-and-forth with FortisAlberta directly so the homeowner isn't the one chasing down paperwork or translating utility terminology. We don't guess at what FortisAlberta needs. We build the application the way they require it, because a rejected or delayed application just pushes back the day the system goes live. Current approval requirements and timelines are FortisAlberta's to set, and we confirm the specifics for each property at design time rather than quoting a general rule that may not hold for every site.

Current Program and Interconnection Review
Utility connection review
FortisAlberta reviews every grid-tied solar application against their current micro-generation interconnection requirements before a system can be switched on. Range Road Solar prepares and submits that design package, including equipment specifications and the single-line diagram, so the application reflects exactly what's being installed.
Current program review
Eligibility for any current residential, farm, or commercial program is reviewed against the rules in place at the time of design, since those rules can change. We check what applies to a given property as part of the design review rather than assuming a program that applied last year still applies today.
