Ground-Mount Solar in Alberta

How this works in Alberta

Ground-mount solar uses land you already have when the roof is shaded, weak, or facing the wrong way. It is often the only honest array on a treed acreage.

A ground mount suits acreages with open south-facing land and a roof that is shaded, small, old or facing the wrong way. The panels sit on racking anchored with piles or footings, and the circuit is trenched back to the house or shop service.

The main yield advantage is angle. NRCan's data for Edmonton shows panels at latitude tilt producing about 1,244 kWh per kW a year, compared with 944 for flat panels and 989 for vertical. Two-axis tracking reaches 1,779, but trackers add moving parts and cost. A steeper tilt (latitude +15°) gives slightly less annual energy, but in Edmonton's December it slightly outproduces latitude tilt (63 vs 58 kWh/kW in NRCan's indicative monthly values).

Regulation-wise, a grid-connected ground mount is handled the same way as a rooftop system: Form A to your distribution owner, an electrical permit, a final inspection, and a check with the municipality for development or building permits. Two extra points apply to ground arrays. The regulation allows the generating unit to sit on adjacent land you own or lease, not only the house parcel. And the AUC notes that wind and solar units may need approval from NAV CANADA, Transport Canada or Alberta Transportation, which is relevant near airstrips and highways.

Before any piles go in, request a utility locate. Soil conditions and frost affect the foundation choice, and the package data notes that an engineer may be needed for the rack design.
