Plug-In Solar PV

Solar for all: a deep dive on a fast-emerging solar segment

12 March 2025

This market overview and policy analysis from SolarPower Europe examines key trends, regulatory frameworks, and best practices for plug-in solar PV across EU Member States. As regulations continue to evolve, standardisation and clear installation guidelines will be key to ensuring safe and efficient deployment.

Plug-in solar photovoltaic (PV) consists of small-scale PV systems, of usually one or two modules, which can be plugged into a grounded home power socket making them a simple and flexible solar solution for households. A common type of plug-in PV is ‘balcony solar.’
 

With Germany leading the way, where up to 780 000 plug-in PV solutions are already registered, other EU markets are beginning to follow suit. As demand rises, product standards and installation guidelines will be critical to ensure safe and efficient deployment across Europe.
 

This report is a valuable resource for policymakers, industry stakeholders, and energy consumers, offering insights into the rapid expansion of plug-in PV highlighting the best practices for streamlining its installation. The report also digs into the importance of developing technical standards and certifications for product safety and installation.
 

Developed with input from leading experts in solar technology, policy, and energy markets, this report provides a blueprint for scaling up plug-in PV across Europe, offering clear guidelines to ensure safe and efficient deployment.
