Quick Answer
Solar arrays in northern climates should be oriented with a south-facing azimuth to maximize energy production. A tilt angle of 30-40 degrees is suitable for most locations in these climates. This configuration allows for optimal energy capture during the winter months.
Choosing the Right Azimuth
When selecting an azimuth for your solar array in a northern climate, consider the local latitude and altitude. A south-facing azimuth is generally the best choice, as it allows panels to receive direct sunlight during the winter months when the sun is lower in the sky. In areas with high solar irradiance, a slightly west-facing azimuth may also be effective.
Tilt Angle Considerations
The tilt angle of your solar array is critical in northern climates, where the sun’s path across the sky changes significantly throughout the year. A tilt angle of 30-40 degrees is often considered optimal for these regions, as it allows panels to capture sunlight at an efficient angle during the winter months. However, the ideal tilt angle may vary depending on your location and the specific solar array configuration.
Factors Influencing Azimuth and Tilt Angle
In addition to the local latitude and altitude, several other factors can influence the optimal azimuth and tilt angle for your solar array. These include tree shading, roof pitch, and local building codes. It’s essential to consult with a qualified solar professional to determine the best configuration for your specific installation. They can assess your site and recommend a customized solution that maximizes energy production and minimizes costs.
