Solar Panel Optimum Tilt Angle

There s a simple rule of thumb for calculating the best tilt angle for fixed mount solar panels.

Solar panel optimum tilt angle.

Optimum angle differs during winter months. In the spring summer and autumn the efficiency is lower 74 75 in spring autumn and 68 74 in summer because in these seasons the sun travels a larger area of the sky and a fixed panel can t. Low angle roofs will also face obstacles when it comes to solar panel installation and may require specialized racking if you re looking to tilt them at the optimal angle. Placing panels flush against these types of roofs will mean less electricity production which will lead to reduced solar savings over time.

For instance if your latitude is 34 the optimum tilt angle for your solar panels during winter will be 34 15 49. How can you determine the optimum angle for solar panels for your state. The solar panel tilt also depends on when you want the panels to produce the most energy. Otherwise your best bet is to set it at an angle that is optimal for the most prevalent.

Therefore the optimal solar panel tilt may change with the seasons. The ideal angle for your solar panels can vary depending on your solar objectives. The optimum tilt angle is calculated by adding 15 degrees to your latitude during winter and subtracting 15 degrees from your latitude during summer. For example if you are seeking to maximise solar generation during winter months be it for an off grid system or higher energy consumption levels you would ideally want to angle your panels at a greater tilt for maximum exposure to the low winter sun.

The summer optimum tilt angle on the other hand will be 34 15 19.
