Balcony photovoltaics / Socket photovoltaics. What they are and how they work
Balcony photovoltaics / Photovoltaics Solar Panels: Balcony photovoltaics and solar panel photovoltaics are systems for generating electricity from solar radiation, designed for home use. These systems are ideal for those who want to reduce their electricity bill and contribute to green energy without the need for large installations.
Photovoltaic Balcony
The balcony photovoltaics are small solar panels that can be placed on the balcony or terrace of a house. These systems usually have a power ranging from 300W to 1kW and can be connected directly to the home's electrical grid. The energy produced can be used directly by the home's electrical appliances, reducing the need for electricity from the public grid.
Photovoltaics Socket
Plug-in photovoltaics are even simpler systems that plug directly into a household outlet. These systems usually have a lower power output (around 200W-600W) and are ideal for people who want to start with a small investment. The energy produced feeds directly into the home's electrical grid, reducing consumption from the public grid.
Balcony Photovoltaics / Socket Photovoltaics: Legal Framework in Greece
In Greece, balcony and socket photovoltaic systems are considered legal, as long as they meet certain conditions:
- Connection License: For systems with a power of up to 800W, a legal framework is expected to not require a connection permit from the Electricity Distribution Network Operator (HEDNO). However, an application for connection must be submitted and the technical specifications must be met.
- Technical specifications: Systems must meet the technical specifications set by HEDNO, such as the use of inverters that meet safety and compatibility standards.
- Net Production Measurement: In Greece, there is the “net metering” system, which allows owners of photovoltaic systems to transfer the generated energy that they do not consume directly to the public grid and recover it when they need it.
- Tax Status: The energy produced by small photovoltaic systems (up to 6kW) is not taxed, as long as there is no commercial exploitation.
Advantages
- Electricity Bill Reduction: The direct use of the energy produced reduces the need for electricity from the public grid.
- Easy Installation: The systems are simple to install and do not require major structural changes.
- Environmentally Friendly: They contribute to reducing carbon dioxide emissions.
Disadvantages
- Limited Power: These systems have low power and may not fully cover the needs of a household.
- Dependence on Climatic Conditions: Energy production depends on solar radiation, which can vary depending on the season and weather.

Balcony photovoltaics / Socket photovoltaics: In summary, balcony and socket photovoltaics are a good solution for those who want to start with small investments and reduce their electricity bill, while at the same time contributing to environmental protection. In Greece, these systems are legal as long as the relevant regulations and specifications are respected.
The new trend for balcony photovoltaics (aka plug-and-play photovoltaics) arrived at Greece opening a new market. After their widespread use in many European countries, they are now also sold in our country in stores selling electrical and electronic devices. With prices of approximately 550 to 600 euros for a photovoltaic system with a 350-watt socket kit. 420 W (watts) one can purchase and install a solar system on their own.
Their widespread use in Germany, Belgium, Austria, France et al. has shown that installing two 400 Watt panels – at an average cost of 1.100 to 1.200 euros – can reduce the electricity bill of a typical household, small shop or company by at least 25%. In fact, the energy generated by the solar panels is immediately distributed to the circuit and powers the devices closest to the kit first.
Lately, the Association of Photovoltaic Companies (SEF)) in Greece is located in discussions with HEDNO so that the rules for these specific systems can be quickly determined and the necessary legislative regulation can then be promoted that will allow their installation only with notification to the Administrator.
The plug-and-play photovoltaics usually consist of two photovoltaic panels, a microinverter and a simple mounting system and are connected directly to a standard building socket. They are also ideal not only for owners like rooftop photovoltaics but also for tenants as well they can take it with them when moving. They are also more efficient as they benefit more, compared to roof panels, even from the "low" winter sun.
What is the situation in Germany?
Balcony photovoltaics are particularly popular in Germany, where last April a new legislative framework was approved that limits any regulatory or regulatory obstacles that existed and clarifies that only one is required simple on-line notification to the electricity provider through a special digital gateway. Today, in Germany the solar panels on balconies exceed 700.000, having doubled since the beginning of 2024, According to data from the competent federal electricity distribution operator BNetzA, the registered systems bring the installed capacity of solar photovoltaic balconies in the country to 600 MW.
In fact, by January 2023 balcony photovoltaics have been exempted in Germany from value added tax (0% VAT) while some municipalities in the country have introduced generous subsidy programs such as the Berlin which offers subsidy of 500 eurosBut also other countries, such as Austria, Britain, the Croatia, the Ireland and the Netherlands have imposed zero VAT on solar systems while other countries (Austria, Belgium, France, Italy, Lithuania, Luxembourg, Poland and Portugal) have adopted various other support measures.
According to the Global Balcony Solar System Market Research Report (2024) the market share of photovoltaic balconies is estimated to reach 4,5 billion dollars by 2032 (from $1,12 billion ensures 2023) by projected annual growth rate of the market to be determined over the next eight years at 16,76%.
