Where Should You Place Solar Panels? A Practical Guide for Maximum Efficiency

Installing solar panels is a great move—but where you place them can make or break your system’s performance. Let’s look at the key factors to consider when positioning your panels.

1. Orientation

In the Northern Hemisphere, south-facing panels capture the most sunlight throughout the day. East or west-facing panels can still work but produce slightly less energy.

2. Tilt Angle

Your panel angle should match your local latitude for optimal year-round performance. Many rooftop mounts are adjustable, especially on flat roofs.

3. Avoiding Shade

Trees, chimneys, or other buildings can cast shadows that significantly reduce output. Use a solar pathfinder or online tool to identify any shading issues over the year.

4. Roof Suitability

Ensure your roof is structurally sound, not too steep, and has adequate space for the number of panels you need. Metal and asphalt shingle roofs are ideal; clay tile can be trickier.

5. Ground-Mounted Alternatives

If your roof isn’t suitable, you can install ground-mounted panels. These allow for perfect orientation and angle adjustments but require space and sometimes permits.

Conclusion

Proper placement = maximum payoff. Work with a qualified solar installer who can assess your site and recommend the most effective layout. With smart positioning, your solar investment will shine for decades.
