Best Angle And Orientation For Solar Panels – Forbes Home
When looking for the right tilt for your solar panels, the latitude rule works in most cases. However, if you live in locations beyond 30-45
Solar panel angle is simply the vertical tilt of your solar panels. It can be a little more tricky to understand since the proper tilt will vary with geographic location and time of year. In terms of geographic location, the angle of your panels will increase the further you move from the equator.
This is done by tilting your solar panels at the same angle as the latitude of your home. For most homeowners, the ideal angle for a solar panel installation is close to or equal to the latitude of your home. This angle is typically between 30 degrees and 45 degrees.
The direction of your solar panels is generally more important than their angle. Most roof tilts will work well, with a few exceptions. Small roof sizes, unfavorable solar policies, and significant shading are far more likely to impact the economic viability of a solar installation than the roof's orientation.
Another reason the angle is critical is seasonal sunlight variation. In summer, the sun is higher in the sky, while in winter, it's much lower. Adjusting the angle of solar panels to match seasonal changes can improve efficiency by up to 20–25% annually.
