Germany Home Photovoltaik-Energiespeicherverarbeitung

Bei kleinen Photovoltaik-Anlagen sollte außerdem die Speicherkapazität der Batterie in Kilowattstunden nicht viel größer sein als die Leistung der Anlagen in Kilowatt. Für einen Haushalt mit einer 5 Kilowattpeak-PV-Anlage und einem Jahresstromverbrauch von 5.000 Kilowattstunden wäre also ein Speicher von rund 5 Kilowattstunden ideal.

Does Germany have a photovoltaic system?

Household photovoltaic systems are a mainstay in achieving the German Federal Government's declared objective of significantly expanding photovoltaics. So far, only a small percentage of Germany's roof surfaces is equipped with photovoltaics. Recently, however, a significant increase in the installation of such systems has been observed.

Why is photovoltaic expansion important in Germany?

Germany is leaving the age of fossil fuel behind. In building a sustainable energy future, photovoltaics is going to have an important role. The following summary consists of the most recent facts, figures and findings and shall assist in forming an overall assessment of the photovoltaic expansion in Germany.

Why are rooftop photovoltaics important in Germany?

The German Federal Government wants to further increase the expansion of photovoltaics (PV). From the year 2026, new capacity installations are to triple from current levels.1 In order to reach this goal, rooftop photovoltaics installed by private households play an important role, partly because these roofs would otherwise remain unused.

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 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.

Does Germany need rooftop photovoltaics to meet climate targets?

To meet climate targets, Germany needs to accelerate the uptake of photovoltaics. Household rooftop photovoltaics, which accounted for more than half of all systems installed in Germany in 2023, play an important role here. But not all regions in Germany are equally suitable for their installation.
