What is the optimal tilt angle for solar panels?
The optimal tilt angle for solar panels is calculated based on your latitude. During winter, add 15 degrees to your latitude, and during summer, subtract 15 degrees from your latitude. For example, if your latitude is 34°, the optimal tilt angle during winter would be 49°, and during summer, it would be 19°.
How to set solar panel tilt angle based on latitude?
The most common answer to this question is to set the angle of your solar panels equal to your latitude. So, if your latitude is 30°, you'd set your solar panel tilt angle to 30° from horizontal. I was curious how accurate this rule of thumb is, so I ran an analysis comparing the solar panel angles derived from latitude to 2 alternative methods:
What is the optimum tilt angle?
The optimum tilt angle is the angle at which solar panels will receive the overall maximum solar radiation over a certain period. Instead of tracking the sun every hour or month, we fix solar panels at this optimum position for a particular period.
How to calculate solar panel angle based on latitude?
To calculate the optimal solar panel tilt angle based on your latitude, add 15 degrees to your latitude during winter and subtract 15 degrees from your latitude during summer. Here are two simple methods for calculating an approximate solar panel angle.
How does a tilt angle affect a PV system?
A change in the tilt angle simultaneously leads to a change in the amount of radiation reaching the surface of the PV panels . However, as a general rule, the tilt angle for a PV array installation is nearly equivalent to the latitude of the area [90,91]. ...
Do solar panels need to be tilted?
When the sun is higher, panels require less tilt. The goal is to catch as much direct sunlight as possible throughout the day and across seasons. So when the sun hangs lower in winter, you’d increase the panel angle. When it’s higher in summer, you’d dial it down a bit. Location is also a key factor.
