What angle should solar panels be installed in Tallinn?

To optimize the efficiency of a solar PV system installed here, it is recommended that panels be tilted at an angle of 49 degrees facing South. However, Tallinn's position within the Northern Temperate Zone presents some challenges for consistent solar power generation throughout the year.

How to optimize solar generation in Tallinn Estonia?

Assuming you can modify the tilt angle of your solar PV panels throughout the year, you can optimize your solar generation in Tallinn, Estonia as follows: In Summer, set the angle of your panels to 42° facing South. In Autumn, tilt panels to 61° facing South for maximum generation.

How much energy does a solar PV system produce in Tallinn?

Average 1.54kWh/day in Autumn. Average 0.50kWh/day in Winter. Average 3.97kWh/day in Spring. To maximize your solar PV system's energy output in Tallinn, Estonia (Lat/Long 59.433, 24.7323) throughout the year, you should tilt your panels at an angle of 49° South for fixed panel installations.

What angle should solar panels be positioned?

In Autumn, tilt panels to 61° facing South for maximum generation. During Winter, adjust your solar panels to a 71° angle towards the South for optimal energy production. Lastly, in Spring, position your panels at a 51° angle facing South to capture the most solar energy in Tallinn, Estonia.

What is the optimum tilt angle for solar panels?

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 instance, if your latitude is 34°, the optimum tilt angle for your solar panels during winter will be 34 + 15 = 49°. The summer optimum tilt angle on the other hand will be 34 – 15 = 19°.

Why do solar panels need a higher tilt angle?

When the sun is lower in the sky, solar panels need a greater tilt angle to receive direct sunlight. 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.
