Feed-in Tariffs (EEG) for Solar Power

One of the cornerstones of Germany’s solar incentive system is the feed-in tariff, established under the Renewable Energy Sources Act (EEG). It guarantees a fixed payment for every kilowatt-hour of solar energy fed into the grid, offering long-term financial security to solar system owners. The feed-in tariff in Germany has played a pivotal role in making solar energy financially viable, especially for small-scale and residential producers.

How the German Feed-in Tariff System Works

The feed-in tariff (FiT) is a government-backed program that ensures solar producers receive a fixed rate per unit of electricity exported to the national grid. Here’s how it works:

• Once your solar system is installed and grid-connected, you’re eligible to register for the EEG tariff.
  
• Your utility company will measure how much electricity you send back to the grid.
  
• You receive monthly or quarterly payments for this exported electricity, based on current feed-in tariff rates.
  

This incentive offers predictable revenue for up to 20 years, helping offset the costs of your system and even generating surplus income.

Key features:

• Applies to residential, commercial, and industrial systems
  
• Payment rates are locked in at the time of registration
  
• Encourages energy independence and faster solar power adoption
  

2025 Feed-in Tariff Rates for Residential and Commercial Solar

As of 2025, the German Federal Network Agency (Bundesnetzagentur) has updated tariff rates to reflect the evolving solar market. While rates decrease over time to match falling system costs, they still offer substantial support—especially when paired with KfW solar loans or tax benefits.

These rates are subject to monthly adjustments, so it’s important to lock in your rate early in the year.

Tip: Combining the FiT with net metering Germany or self-consumption strategies can boost total savings and energy efficiency.

Step-by-Step Guide to Applying for Feed-in Tariffs
