Solar Potential in County of St. Paul

County of St. Paul sits in a part of Alberta where summer sun is generous and winter sun is not. Regional NASA POWER-style figures for this belt are about 6.2 kWh/m²/day in high summer and about 0.8 kWh/m²/day in mid-winter. Those figures are horizontal irradiance from the report pipeline's insolation tables for a representative quarter in the county, not a measured year on your roof.

That winter number is the one that sizes batteries, not the July brochure.

Open farmland between the lakes gives a decent summer figure. Winter sun is thin, and many farmsteads are sheltered by mature spruce that shade a south roof.

Why county solar is not a system quote

Irradiance is energy hitting a horizontal square metre. A real array has tilt, azimuth, snow, soiling, inverter losses, and shade. Two parcels a kilometre apart in County of St. Paul can differ more from trees and roof geometry than from climate.

Use the county figures this way:

A grid-tied system near St. Paul can lean on the summer surplus. An off-grid cabin in County of St. Paul has to live on the winter number or on a generator.

Shade, snow, and chinook

Walk the site on a low-sun day if you can. Mark:

County of St. Paul is not the desert, but it is not coastal cloud either. Snow slides off a steep enough rack after a chinook more readily than after a still cold week. Design the rack for both.

A simple sizing sketch (not an electrical design)

For a household that uses 10 kWh/day in January:

If that area does not fit the south roof, you need ground-mount, load cuts, or a hybrid. The free parcel report will not replace an electrician, but it will show whether the land even faces the problem honestly.

Hardiness and frost-free days (about 105 in this county) also matter: a food-garden pump in May is a different load than a heated shop in January.

Sampled from the live report pipeline at a representative quarter in Township 57, Range 9, W4 on 2026-10-08: well depth, hardiness zone, solar irradiance (115 well records within 5 km). Text reviewed 2026-10-09. Methodology.

Common questions

Is winter solar enough in County of St. Paul?

Winter irradiance here is low. Grid-tied systems still work. Off-grid systems must be sized on the winter number or paired with a generator.

Should I clear trees for solar in County of St. Paul?

Only after you map December shade and any shelterbelt you still want. Clearing is a design choice, not a default.
