Germany's Balkonkraftwerk Boom: Small Solar Systems Double in 2024

Over 780,000 plug-in solar devices are now in use, driven by legal reforms, subsidies, and falling costs.

Germany saw a record 430,000 new Balkonkraftwerke, or plug-in solar devices, installed in 2024, doubling the total to over 780,000 units.
The combined capacity of these small solar systems now reaches 0.7 gigawatts, with projections suggesting the millionth unit could be installed by mid-2025.
Key drivers include legal changes making it easier for renters and property owners to install devices, as well as tax exemptions and local subsidies of up to €500.
New regulations allow higher output capacities of up to 800 watts per unit, improving efficiency and increasing interest in these systems.
Experts predict sustained growth in 2025, with Germany becoming a global model for regulatory and technical frameworks for small-scale solar energy.
