Shop Solar in Lethbridge, Alberta for Shops and Outbuildings

Solar Planning for Lethbridge Properties

Shops, heated garages, barns, and outbuildings carry loads that are often separate from the main residence but still show up on the same power bill. That matters when you're sizing a solar system, because the goal is to offset the combined draw across all the buildings on the property, not just one of them. In Lethbridge, Alberta, properties range from light industrial lots on the edge of town to working farms where a shop and an irrigation system share the same service entrance. The electrical setup varies considerably, and that variation is exactly why we start with a site review rather than a rule-of-thumb number. We look at the existing panel, the meter base, the roof pitch and orientation of your shop, and whether ground-mount is a better fit for your yard layout. We're also looking at the 12-month usage graph on your most recent power bill, because that graph tells us far more about your actual consumption pattern than any estimate we could make from square footage alone. Properties tied to the City of Lethbridge grid go through a specific interconnection process, and we handle that application on your behalf. The design review is free, and it's the only honest way to know what a system will actually do for your property.

Yes. Shops and outbuildings connected to the City of Lethbridge distribution system are eligible for grid-tied solar through the city's micro-generation program. The application requires a design package that documents your system's equipment and single-line diagram, and Range Road Solar prepares and submits that on your behalf. We design the system to meet the City of Lethbridge's technical requirements before anything goes in. The interconnection process is specific to the city as the wire service, so working with an installer who knows that process matters.

That depends on where your biggest loads are and how the electrical service is set up on your property. If the shop and the house are on the same service entrance and meter, we design from the combined consumption data. If they're on separate meters, we can look at them independently or together depending on what makes sense for your situation. The 12-month usage graph on your most recent power bill is where that analysis starts, and we'll walk you through what the data shows during the design review.

Shop systems in and around Lethbridge generally fall in the 8-20 kW range, with 12 kW being a common starting point for a property with a heated shop and some additional loads. But the right size for your property depends on your actual consumption data, the roof or ground-mount conditions, and what loads you're trying to offset. We don't size systems from estimates. We pull the 12-month usage graph from your most recent power bill and build the design from there.

Both configurations work well for shop and outbuilding projects, and the right call depends on your specific property conditions. If your shop roof faces roughly south, has a workable pitch, and isn't shaded by trees or nearby buildings, rooftop is usually the simpler install. If the roof orientation is off or shading is a problem, a ground-mount array gives us full control over tilt and direction. We look at both options during the site review and recommend whichever one produces the better design outcome for your property.

We install LONGi solar panels and APsystems microinverters on shop and outbuilding projects. LONGi panels are well-suited to the metal and steel-truss roofs common on shops and agricultural buildings, and they work in both rooftop and ground-mount configurations. APsystems microinverters operate at the panel level, so shading or obstructions on one part of the array don't drag down production from the rest of it. That panel-level independence matters on shop roofs where partial shading from a nearby structure is sometimes unavoidable.

The main thing we need is your most recent power bill. Alberta utility bills include a 12-month usage graph that shows your seasonal consumption pattern, and that's the data we use to size your system accurately. Beyond that, it helps to know roughly how your shop is used, what major equipment is running, and whether there are other significant loads on the property like irrigation or grain handling. We'll ask the right questions during the review.

Not always, but it depends on the age and capacity of your existing panel. Older shop panels sometimes don't have the breaker capacity to support a solar backfeed, or they're a model that doesn't accept a solar breaker safely. We check breaker capacity and panel condition during the site review. If an upgrade is needed, we include it in the project scope before we finalize the design so there are no surprises during installation. It's better to know that upfront than to find out partway through the job.
