Expected ROI of photovoltaic ESS project in Germany 2026

What is the growth rate of photovoltaics in Germany?

The annual growth rate during this period is eight per cent. The expansion also includes the replacement of old PV systems ("repowering"), which is currently still marginal, but could amount to up to 15 GWp/a in the phase after 2040. Looking at the historical market development, two growth phases of photovoltaics in Germany can be distinguished.

How will photovoltaic capacity grow in 2026?

Annual targets can also be derived from the federal government's plans, which illustrate the growth pattern: The coming years will be characterised by strong, double-digit growth in photovoltaics. The annual increase in capacity is set to rise to over 22 GWp/a from 2026. By way of comparison, a record 14 GWp of new capacity was added in 2023.

What are Germany's most anticipated solar projects?

1. Verbund Visiolar Germany solar PV park The Verbund Visiolar solar PV park is a sizable project planned near Berlin, with a capacity of 2,000 MW. This solar plant will span 3,459 acres at first, with plans to expand further across 49,421 acres. Its sheer scale makes it one of Germany’s most anticipated solar projects.

How will photovoltaics transform Germany?

The focus of this transformation is decarbonisation, which is being driven forward by the German government with ambitious targets. The goal: increased resilience. The accelerated expansion of photovoltaics (PV) plays a central role in this transformation. A complex task that opens up new design and growth options.

What is the market share of Bess batteries in 2023?

With a 72.3% market share, lithium-ion batteries dominate grid scale BESS applications and are set to remain the top choice for future needs. Germany led the European BESS market in 2023, with a 34% share, followed by Italy at 22% and the UK at 15%.

Are rooftop PV systems paired with battery storage in Germany?

In 2019, 46% of all commissioned residential rooftop PV systems had already been paired with battery storage systems. Remarkably, this share surged to 77% in 2023, indicating a significant upward trajectory of the trend toward combining PV residential rooftop systems with battery storage in Germany.
