Infographics about Plug-in PV system

What is a plug-in PV system and what are the advantages of using it?

Discover the answers by exploring a gallery of six infographics created by the EUKI project SUNRISE – Prosumer Solar Energy. This project is being implemented by Habitat Bulgaria in collaboration with the lead organization, Initiative for Housing in Eastern Europe (IWO), and partners including the Lithuanian Consumers Alliance (LCA), Habitat for Humanity International (HFHI), the German Solar Energy Society (DGS), and Habitat Macedonia. The project's primary objective is to address and overcome barriers hindering the adoption by households in multi-family residential buildings of renewable energy, with a specific focus on solar energy.

In Bulgaria, the adoption of photovoltaic systems for balconies and facades with a plug-in socket (Plug-in photovoltaic with installed power up to 800W) remains less popular when compared to Western European countries, where an increasing number of households are embracing this technology. These photovoltaic systems offer a cost-effective solution with substantial potential to educate citizens about the benefits of utilizing solar energy. They can serve as an incentive for individuals to consider installing higher capacity solar energy systems in residential buildings.

The project advocates for the implementation of tools that facilitate and incentivize households to adopt plug-in PV systems. This includes the introduction of net metering for energy production and consumption on an annual basis. The project aims to contribute to the European Union's ambitious targets of achieving a 55% reduction in greenhouse gas emissions by 2030 and attaining carbon neutrality by 2050. Its importance is  evident in the current context, where soaring energy prices put an emphasis on  utilizing renewable energy for electricity generation, even at the household level.


This project is part of the European Climate Initiative (EUKI). EUKI is a project funding instrument of the German Federal Ministry for Economic Affairs and Climate Protection (BMWK). The EUKI competition for project ideas is run by the German Society for International Cooperation (GIZ). The overall objective of EUKI is to promote climate cooperation within the European Union (EU) in order to reduce greenhouse gas emissions.
