Quick Answer
Adjust the tilt of your solar panels every 5-10 years, or whenever you notice a significant decrease in energy production due to shading or changing sun angles.
Adjusting for Seasonal Variations
When installing solar panels on a ground mount pole, it’s essential to consider the changing sun angles throughout the year. A general rule of thumb is to adjust the tilt between 20 and 40 degrees, depending on your latitude. For example, if you’re located at 35°N latitude, a 30-degree tilt is usually optimal.
Monitoring Energy Production
To determine if your solar panels need an adjustment, monitor their energy production over time. A decrease of 10-20% in energy production could indicate shading or a mismatch between the panel tilt and sun angle. You can use a solar monitoring system to track your energy production and identify any issues.
Practical Tips for Adjusting Tilt
To adjust the tilt of your solar panels, loosen the mount’s screws and use a level to ensure the panels are properly aligned. For a ground mount pole, you can use a turnbuckle or a cam lock system to adjust the tilt. Be sure to re-tighten the screws securely after making any adjustments.
