Flexible solar modules: The smart alternative to conventional solar modules – ideal for renters and city dwellers

More and more people want to generate their own solar power – even without a large roof or a house in the countryside. Flexible solar modules offer a simple, space-saving solution for precisely this need. They are significantly smaller than conventional solar panels, weigh only around 4 kg each, and can be easily installed by one person – without any drilling, clamps, or heavy tools. They are an ideal choice, especially for balconies where space is limited and rigid modules often lack flexibility. 

Whether used individually or as part of a balcony power plant: The flexible solar panels adapt to curved or uneven surfaces and open up entirely new possibilities for electricity generation in urban areas. They are perfect for renters, apartment owners, or anyone who wants to generate energy sustainably and independently – and even portably: The modules can be removed without leaving any residue and easily taken along when moving.

An overview of the advantages of flexible solar modules

Flexible solar panels offer a number of practical advantages over conventional, rigid panels – especially for use on balconies of rented apartments or at mobile locations. Here is an overview of the most important advantages:

• Lightweight and compactWeighing only about 4 kg per module and with significantly smaller dimensions than conventional panels, they are easy to transport and can be easily installed by one person.
• Flexible & adaptableThe flexible structure allows installation on curved, uneven or difficult surfaces – ideal for balcony railings, facades or other special surfaces.
• Effective when mounted vertically 
  Flexible solar panels also work when mounted vertically – for example, directly on a balcony railing or fence. Especially in autumn and winter, when the sun is lower in the sky, sunlight hits vertically mounted panels at a favorable angle. This allows for good energy yield even when the sun is low – without the need for complex tilting systems.
• Tool-free assemblyFlexible modules can be attached without any drilling or clamping – for example, with robust Velcro straps. This saves time, effort, and hassle with the landlord.
• Disassembly without residue: When moving, the modules can simply be removed and taken along – perfect for tenants who want to remain independent in the long term.
• Inconspicuous designThanks to their slim design and flexible shape, the modules blend discreetly into the balcony look – without disturbing the aesthetics of the facade.

Balcony power plants with flexible solar modules – the plug-and-play solution for your home

Balcony power plants are becoming increasingly popular – because they offer a simple way to generate your own electricity and actively reduce your electricity bill. Combined with flexible solar modules, the whole process becomes even more convenient and versatile. The modules are lightweight, space-saving, and can be attached directly to the balcony railing or facade – without drilling, structural analysis, or complicated mounting systems.

A balcony power plant with flexible modules typically consists of four solar panels and a compact inverter. This inverter converts the generated direct current into standard household alternating current, which is fed directly into the home's electrical grid via a wall socket. This allows the generated electricity to be used directly by household appliances – without any complex modifications or electrical installations.

Especially for tenants and apartment owners in multi-family buildings, balcony power plants with flexible modules offer a simple way to actively participate in the energy transition – even without roof space or structural changes.

In the PVundSO online shop you will find both flexible solar modules and balcony power plants as a suitable complete set, which are precisely tailored to this purpose – including high-quality flexible solar panels, suitable micro-inverters and secure mounting solutions.

Frequently asked questions about our flexible solar modules

Do I need a permit for a balcony power plant with flexible modules?

Yes, in Germany, installing a balcony solar power system generally requires the consent of the landlord or homeowners' association, as it constitutes a structural alteration. However, a law was passed in July 2024 classifying plug-in solar devices as privileged structural alterations. This means that landlords or homeowners' associations can only prohibit installation in exceptional circumstances.

How are flexible solar panels attached to a balcony?

Flexible solar panels are easy to attach to balcony railings due to their light weight and flexibility. Velcro straps or cable ties are often used for this purpose, eliminating the need for drilling or permanent alterations to the building. This simplifies installation and is particularly advantageous for renters.

How much electricity can I generate with a flexible balcony power plant?

Electricity generation depends on the output of the installed modules and local conditions. In Germany, balcony power plants with a maximum inverter output of 800 watts are permitted. Actual electricity production varies depending on solar irradiance, orientation, and the tilt angle of the modules.

As a tenant, am I allowed to install flexible solar panels?

Yes, tenants are generally allowed to install flexible solar panels, but they need the landlord's permission, especially if structural alterations are made or the building's exterior appearance is affected. With the new law from July 2024, which classifies plug-in solar devices as privileged structural alterations, landlords can only refuse installation in exceptional cases.

Can I simply take the modules with me if I move?

Yes, flexible solar panels are designed to be easily disassembled and transported. Thanks to non-permanent fastening methods such as Velcro straps, they can be removed without leaving any residue and reinstalled at a new location.

What is the difference between flexible and rigid solar panels?

Flexible solar panels are made of thin, bendable materials, allowing them to be installed on uneven or curved surfaces. They are lighter and easier to handle than rigid panels. Rigid solar panels, on the other hand, are made of solid materials such as glass and aluminum and are less adaptable, but often offer higher efficiency and a longer lifespan.

Do I need to register my balcony power plant with flexible modules?

Yes – in Germany, balcony power plants must be registered, regardless of whether rigid or flexible solar panels are used. The system must be registered with the Federal Network Agency's Market Master Data Register and with the local grid operator. Since 2024, the process has been significantly simplified: An informal notification is now sufficient for the grid operator. Approval is no longer required. Registration in the Market Master Data Register is done online and only takes a few minutes.

What happens to excess electricity?

The electricity generated by a balcony solar power system is primarily used in the household. If more electricity is produced than is currently needed, the surplus flows into the public grid – without compensation. To maximize self-consumption, it is recommended to use energy-intensive appliances (such as washing machines or dishwashers) during the day when the system generates the most energy.
