Germany's balcony solar boom (2023-2026)
Germany legalized plug-in solar panels, called Balkonkraftwerk, and they became a household staple. Millions of Germans now plug small panels into wall outlets on balconies and patios.
Plug-in solar became a mainstream consumer product sold in hardware stores across Germany.
Germany's experience showed the technology works safely at scale and can cut household bills without rooftop installation.
California's law follows the German model, which advocates cite as proof that plug-in solar is safe and popular.
