Finding the Best Location for a Solar Array in Northern Michigan

Installing a solar array is one of the best long-term investments you can make for energy savings and sustainability. In Northern Michigan, with its mix of seasonal sun, tree cover, and varied roof styles, choosing the optimal location for your solar system is key to maximizing performance.

1. South-Facing is Best

In Northern Michigan, solar panels produce the most energy when they face true south. This orientation receives the most consistent sunlight throughout the day and across the seasons. Roofs that face east or west can still work well, but they typically produce 10-20% less energy than a south-facing system.

Ideal roof orientations:

  • South (180°) — best overall
  • South-East (135°) or South-West (225°) — very good
  • East or West — workable, especially with more panels

2. Roof Pitch Matters

The angle (pitch) of your roof affects how much sunlight your panels receive. In Northern Michigan, a tilt close to the latitude — around 42°–45° — is near ideal. However, most roof pitches between 20° and 45° will work efficiently with modern solar mounting systems.

3. Avoid Shading from Trees and Structures

One of the biggest challenges in Northern Michigan is shade — especially from tall hardwoods and pines. Even partial shading can significantly reduce a system’s output.

Tips to reduce shading issues:

  • Evaluate shading during spring through fall (not just winter)
  • Consider trimming or removing obstructive tree limbs
  • Avoid placing arrays near chimneys, dormers, or tall neighboring buildings

4. Ground-Mounted vs Roof-Mounted Arrays

If your roof isn’t ideal, due to poor orientation, shading, or structural limitations, a ground-mounted system can be a strong alternative.

Ground array advantages:

  • Flexible orientation and tilt optimized for solar gain
  • Easier maintenance and cleaning
  • Often better cooling airflow for higher efficiency

Best yard locations share these traits:

  • Open space facing south
  • Minimal shading between 9 AM — 3 PM
  • Easily accessible for wiring to your main service panel

5. Seasonal Sun Angles in Michigan

Northern Michigan experiences large seasonal shifts in the sun’s angle:

  • Summer sun is high, so flatter tilts capture more energy
  • Winter sun is lower, so steeper tilt can help — especially if you want winter generation

A fixed system usually aims for a compromise tilt, but adjustable racks can help capture more energy seasonally.

6. Get a Free Professional Solar Assessment

Every property is different, especially in Northern Michigan. That’s why a professional site assessment is one of the most important steps in going solar and it doesn’t have to cost anything.

With a free solar estimate, our team can:

  • Evaluate your roof and yard for the best array location
  • Analyze shading throughout the year
  • Confirm structural and electrical compatibility
  • Recommend system size, layout, and production expectations

A free assessment gives you clear answers and real numbers, so you can make an informed decision with no pressure and no obligation.

Bottom Line

For most homeowners in Northern Michigan:

South-facing, unshaded roof sections are ideal
Ground-mounted arrays offer flexibility when roofs fall short
Minimal shade between 9 AM and 3 PM maximizes output
✔ A tilt near 42°–45° balances energy through the year

Whether on your roof or in your yard, strategic placement makes all the difference in how much clean energy your solar system will produce.
