Do solar panels tilt and azimuth angles matter?

When it comes to installing solar panels, the way they’re positioned matters just as much as the number of panels you have. A key part of maximizing your energy output involves setting your panels at the right solar tilt and azimuth angles.

Should solar panels be tilted?

Solar panels perform best when sunlight strikes them directly, rather than at a slant. A poor tilt can lead to shading, reflection, and reduced absorption of photons, all of which translate into energy loss. By setting panels at the right angle, homeowners and businesses can maximize energy yield and ensure a faster return on investment (ROI).

What angle should a solar panel be tilted?

If you want a low-maintenance setup, the best general advice is to tilt your panels at the same angle as your latitude. This gives you the best average performance across all seasons. For example, San Diego is at a latitude of about 33° north, so a tilt of 33° is ideal if you don’t plan to make seasonal adjustments.

Why is the tilt of solar panels important?

The tilt of the panels is important because your panels will produce a maximum of energy when the sun is directly perpendicular to them. During the winter in the northern hemisphere, for example, the sun is low in relation to the horizon. In this case, for the solar panels to get their best performance, a steep angle of 60° is best.
