So, calculated on https://pvwatts.nlr.gov/pvwatts.php, a 10kW array at the optimal fixed angle of about 40* will produce 13,253 kWh over a year, which would be about one household’s energy use averaged over the year but would fall short quite a lot in winter months:
Chart of energy produced/used for a 10kW array and the electricity pattern of a gas-heated Winnipeg home (12kWh/yr):
A ground mount array of 18 - 550W bifacial panels would present about 45m2 of panel but to put them in a “farm” without shading from solsice to solstice would cover 86m2.
Speaking from experience, I run 23kWh of panels on an offgrid home and I have to supplement with a generator for about 6 weeks of the year even with 43kWh of battery storage. I’m also further north than Winnipeg.
