Balcony Solar Panels
Small plug-in photovoltaic systems can provide a practical way to produce solar energy from a balcony or other suitable space. The applicable framework includes specific power limits, technical requirements and safety conditions.
Key Power Limits
The current framework provides a specific category for small photovoltaic systems with a plug-in connection.
⚠️ Important Implementation Update
The current framework provides for small plug-in photovoltaic systems, but their legal operation is linked to specific safety specifications and the required administrative process. According to the current information on the page, the special safety specifications are expected to be published by 31 October 2026.
A Balcony Solar System Is Not Simply “Plug It In”
Although these systems are small, their installation and operation still require appropriate equipment, electrical checks and compliance with the applicable technical and administrative requirements.
Up to 800 W Production
The maximum production power of the microinverter is 800 W under the framework described on this page.
Up to 1,000 W Installed
The total installed power can reach up to 1,000 W, subject to the applicable conditions.
Battery Compatibility
The system can be combined with energy storage, provided that the required technical and regulatory conditions are met.
Electrical Declaration
An active Electrical Installer Declaration (Y.D.E.) is one of the requirements described for the installation.
Smart Meter
A remotely monitored or “smart” electricity meter is provided for this category of system.
Electronic Notification
The required electronic notification to DEDDIE must be completed before operation according to the applicable procedure.
Balcony Solar Panels With a Battery
Battery storage can be combined with a small plug-in photovoltaic system, subject to the applicable technical, safety and administrative requirements.
🔋 What Does the Battery Do?
A battery can store solar energy produced during periods when consumption is lower and make that energy available later, depending on the configuration of the system.
- Stores excess solar production
- Allows energy to be used later
- Can increase self-consumption
- Requires appropriate protection and management
⚠️ Important
The legal possibility of combining a balcony photovoltaic system with a battery does not by itself mean that every system can immediately be installed and operated. The applicable technical specifications and procedure must be completed.
- Correct equipment selection
- Battery management system
- Required electrical protections
- Compliance with safety specifications
What Should Be Checked Before Installation?
Small system size does not eliminate the need for an electrical inspection and suitable protection.
Solar Panels
Panels suitable for the installation, with secure mechanical mounting and appropriate electrical connections.
Microinverter
The microinverter must be suitable for the application and meet the required operating and protection standards.
Anti-Islanding Protection
Appropriate protection is required so that the system does not continue feeding the grid when grid voltage is lost.
Home Electrical Installation
The existing electrical installation and the circuits connected to the system must be checked for suitability.
Battery & Protection
Where storage is used, the battery, management system and corresponding electrical protections must be suitable.
Meter & DEDDIE Procedure
The applicable requirements concerning the meter, electronic notification and supporting documentation must be fulfilled.
How the Process Is Expected to Work
A specific sequence of technical and administrative steps must be followed before legal operation.
Installation Check
Check the location, mounting, electrical installation and safe connection possibilities.
Equipment Selection
Select the panels, microinverter, battery and required protection equipment.
Declaration
Ensure the active Y.D.E. and required installer or engineer declaration are in place.
DEDDIE Notification
Submit the required electronic notification and supporting information.
Operation
Operation requires full compliance with the technical specifications and applicable procedure.
What Happens to Surplus Energy?
⚡ Surplus Electricity Is Not Compensated
For this specific category of systems, electricity that is incidentally exported to the grid is not compensated. Therefore, incidental grid injection should not be confused with commercial electricity sales or financial compensation.
Practical Restrictions
Installation depends not only on the equipment but also on the grid, the property and the ownership status.
Grid Restrictions
DEDDIE may exclude specific lines or areas for reasons related to grid safety or network congestion.
Rented Property
If the property is rented, the required consent of the owner must be obtained before installation.
Shared Building Areas
Installation on a shared façade, balcony railing or other common area may require checking the building regulations and obtaining co-owner consent.
Frequently Asked Questions
Can I buy a plug-in solar panel system and use it now?
Not during the current implementation phase described on the page. The required safety specifications and procedure must first be completed.
Can I have a battery?
Yes. The framework provides for combining the system with a battery, subject to the applicable technical and regulatory requirements.
Do I need a connection contract?
For this specific category, the described procedure provides for electronic notification rather than the standard connection-contract process.
Do I need an active Y.D.E.?
Yes. An active Electrical Installer Declaration is one of the stated requirements.
Do I need a smart meter?
A remotely monitored or smart meter is provided for this category of system.
Am I paid if electricity is exported to the grid?
No. For this specific category, incidental electricity exported to the grid is not compensated.
Can DEDDIE prevent the installation?
Specific grid lines may be excluded for reasons related to safety or network congestion.
Can a tenant install one?
A tenant needs the required consent from the property owner, while lease and building rules should also be checked.
