Rising electricity bills are forcing more and more people living in apartment blocks to look for alternative solutions. Balcony photovoltaic systems are an innovative solution that allows residents of multi-family buildings to produce their own clean energy and significantly reduce monthly electricity costs.
At Onninen, we offer comprehensive solutions for photovoltaics and energy storage systems, enabling the potential of every balcony to be utilized. Our experience in the installation industry allows us to provide professional products and expert technical advice for installers and individual clients.
Balcony micro-installations are the only way for residents of apartment blocks to independently produce electricity, which can bring real savings from the very first month of use.

How a photovoltaic installation works on a balcony
A balcony photovoltaic installation is fundamentally similar to traditional roof systems - they operate on the same principle of converting solar energy into electricity. The main difference is the scale and method of installation.
On a standard balcony, 1-2 photovoltaic panels with a total power of up to 800 W can be installed. Photovoltaic panels are mounted on the railing or balcony structure, where they capture energy from sunlight and convert it into direct current.
Key components of the balcony system
- Photovoltaic panels - usually with a power of 300-500 W each
- Microinverter - converts direct current to alternating current
- Mounting system - specially adapted to the railing
- Cabling - weather-resistant
- Bidirectional meter - in the case of on-grid installations
The direct current from the panels goes to the microinverter, where it is converted into alternating current. In an on-grid system, the produced energy first powers household devices, and any surplus goes to the power grid.
Types of balcony installations
Depending on needs and technical conditions, we can choose one of three types of installations:
| System type | Characteristics | Advantages |
|---|---|---|
| On-grid | Connection to the power grid | Sale of surpluses, settlements with the energy company |
| Off-grid | Island system with energy storage | Independence, emergency power supply |
| Plug & Play | Connection to a household socket | Simplicity of installation, no formalities |
Costs of installation and profitability of balcony photovoltaics
One of the biggest advantages of balcony photovoltaics is the relatively low investment costs compared to roof installations. The cost of a complete set ranges from 3000 to 6000 PLN, depending on the power and quality of the components.
Cost structure of balcony installation
- Photovoltaic panel 400-500W: 700-1200 PLN
- Microinverter: 400-800 PLN
- Mounting system: 300-500 PLN
- Cabling and accessories: 200-300 PLN
- Professional installation: 500-1000 PLN
Our experience shows that a 600W installation can produce 500-700 kWh of energy annually, which at current electricity prices means savings of around 400-600 PLN per year. The payback period for the investment is usually 6-10 years.
Factors affecting profitability
The financial efficiency of balcony photovoltaics depends on several key factors:
- Orientation of the balcony - the best is a south or southwest exposure
- Shading - even partial shade can reduce efficiency by 20-30%
- Energy consumption profiles - optimal for people staying at home during the day
- Local climate - number of sunny days per year
- Energy prices - rising tariffs increase profitability
Formal requirements and installation of photovoltaics in apartment buildings
Installing photovoltaics on a balcony in a multi-family building requires meeting certain formal requirements. The key is the consent of the building manager or housing community, especially if the panels are to be mounted on the outside of the railing.
Procedure for obtaining consent
As experts in the field of installations, we recommend the following procedure:
- Submitting an application to the manager/community with the installation project
- Presenting the technical specifications of the devices
- Indicating a safe installation method for the building structure
- Declaration of professional installation by a qualified electrician
For installations with a power above 800W, it is also necessary to notify the energy company and replace the meter with a bidirectional one. Plug & play installations with a power of up to 800W often do not require additional formalities.
Safety requirements
The safety of the installation is a top priority for us. Key requirements include:
- Professional installation by a qualified electrician
- Resistant structure secured against strong winds
- Proper electrical protections in accordance with standards
- Regular inspections of the technical condition of the installation
Selection of components for balcony installation
The choice of appropriate components is crucial for the efficiency and durability of the installation. In Onninen's assortment, you will find proven solutions from renowned manufacturers, tailored to the specifics of balcony installations.
Photovoltaic panels for balconies
Due to limited space, photovoltaic panels for balconies should feature high power per unit area. We recommend monocrystalline modules with a power of 400-500W, which provide optimal performance even in limited space.
Our panels feature:
- High efficiency exceeding 20%
- Resistance to harsh weather conditions
- Long-term performance warranty - 25 years
- Aesthetic design that fits the architecture of the building
Microinverters and mounting systems
Microinverters are particularly suitable for balcony installations, allowing each panel to operate independently. In Onninen's offer, you will find microinverters with power adapted to balcony panels, ensuring maximum energy conversion efficiency.
The mounting systems in our offer are specially designed for mounting on various types of railings. They provide safe and aesthetic mounting of panels without damaging the balcony structure.
Energy storage for balcony installations
Energy storage systems dedicated to small installations are becoming increasingly popular. They allow for storing surplus energy produced during the day and using it in the evening or at night.
The energy storage systems offered by Onninen feature:
- Compact sizes - ideal for apartments
- LiFePO4 technology - safe and durable
- Easy integration with existing installations
- Energy management systems optimizing consumption
A small energy storage system with a capacity of 2-5 kWh can significantly increase the self-consumption of produced energy, enhancing the economic efficiency of the entire installation.
Frequently asked questions
1. How much does a photovoltaic installation on a balcony cost?
The cost of a complete balcony installation ranges from 3000 to 6000 PLN. The price depends on the power of the panels, the quality of the components, and the scope of installation. A basic set with two 400W panels costs around 4000 PLN including installation.
2. How much energy will balcony photovoltaics produce?
A 600W installation can produce 500-700 kWh annually. Efficiency depends on the orientation of the balcony, shading, and local climatic conditions. The best exposure is south without shading.
3. Do I need permission to install panels on the balcony?
Yes, permission from the building manager or housing community is required. This particularly applies to installations on the outside of the railing. Socket installations with a power of up to 800W have simplified procedures.
4. When does the investment in balcony photovoltaics pay off?
The payback period is 6-10 years at current energy prices. For an installation costing 4000 PLN and annual savings of 500 PLN, the investment pays off after 8 years. Rising electricity prices shorten this period.
5. What orientation is best for photovoltaics on a balcony?
The best orientation is south or southwest. This allows for maximum utilization of sunlight. East and west balconies can also be effective, but with lower efficiency.
6. Can I add energy storage to a balcony installation?
Yes, small energy storage systems of 2-5 kWh work perfectly with balcony installations. They allow for storing surplus energy and using it in the evening, increasing self-consumption to 70-80%.
7. Does balcony photovoltaics require maintenance?
Minimal maintenance - periodic cleaning of panels and checking connections. Modern systems are practically maintenance-free. We recommend a technical inspection once a year by a qualified electrician.
