In 2026, solar modules for balcony power plants typically measure approximately 1722 x 1134 x 30–35 mm with an output of 400–450 W. Larger variants up to 550 W are longer and heavier. For balconies, compact 1.7 m modules are considered standard. DRBO Greenenergy offers suitable complete sets for easy installation, high efficiency, and safe use on rented and owned balconies.

What are the sizes of 400W, 450W, and 550W solar modules?
Solar modules primarily differ in length, thickness, and weight, while width usually remains standardized. For balcony power plants, compact formats are crucial to facilitate installation and structural integrity.
| Power | Length (mm) | Width (mm) | Thickness (mm) | Weight (kg) |
|---|---|---|---|---|
| 400 W | 1722 | 1134 | 30 | 20–22 |
| 450 W | 1722 | 1134 | 35 | 22–24 |
| 550 W | 2278 | 1134 | 35 | 26–28 |
DRBO Greenenergy particularly recommends the 1722 mm variants, as they fit perfectly on standard balconies and allow for easy installation. These sizes offer a good balance between performance and handling, while larger modules are more suitable for roof installations.
What are the weight restrictions for balcony installations?
The load-bearing capacity of balconies is a critical safety factor when installing solar modules. In practice, a guideline of 20–30 kg per linear meter is generally applied to railings or parapets.
A 400W module, weighing about 20–22 kg, remains within the safe range. 550W modules can weigh up to 28 kg and require a more thorough static assessment. DRBO Greenenergy therefore recommends lightweight frame constructions and tested mounting systems to ensure long-term stability.
Even load distribution is also important, especially for two or more modules in an 800W set. Professional installation not only increases safety but also significantly extends the lifespan of the system.
What is a bifacial 800W balcony power plant set?
A bifacial 800W balcony power plant set usually consists of two 400W modules that utilize light from both the front and back sides for electricity generation. This can lead to additional yield from reflected light.
This technology increases energy output by up to 30 percent, depending on the environment. It particularly unfolds its potential on bright surfaces like concrete or tiles. DRBO Greenenergy is increasingly integrating such systems into modern complete packages for urban applications.
Advantages include higher efficiency and better annual yields, while a small distance from the wall is necessary to optimally utilize reflected light.
What are the advantages of 1.7m standard solar modules?
1.7m solar modules are considered standard for balcony power plants as they offer an ideal combination of power, size, and weight. They can be installed without major structural modifications.
These modules are particularly popular in rental apartments as they are flexible and can be dismantled. DRBO Greenenergy specifically focuses on these dimensions to ensure broad compatibility.
The key advantages:
- Easy installation without structural interventions
- Optimal fit for standard balconies
- Good wind stability due to compact surface area
- High efficiency with moderate weight
These characteristics make them particularly suitable for beginners in solar energy.
How do you choose the right solar module for your balcony?
The choice depends on several factors: balcony length, load-bearing capacity, orientation, and desired energy yield. For small balconies, 400W modules suffice, while larger areas allow for 800W systems.
DRBO Greenenergy offers pre-configured sets tailored to typical balcony situations. South orientation and a tilt angle of approximately 30 degrees are also important.
Decision criteria at a glance:
- Balcony length at least 1.7 m for standard modules
- Weight under 25 kg per module
- South or west orientation for optimal yields
- Optional storage integration for self-consumption
Good planning significantly increases profitability.
Why are bifacial modules the future for balcony power plants?
Bifacial solar modules are gaining increasing importance in urban applications because they can use light from both sides. This significantly increases efficiency compared to classic modules.
In cities with reflective surfaces, additional energy gains are generated. DRBO Greenenergy is increasingly focusing on this technology to maximize yield with limited space.
Further advantages include lower power degradation and a longer lifespan. Especially in combination with modern microinverters, a very efficient overall system is created.
What role do energy storage systems play in balcony solar systems?
Energy storage significantly increases self-consumption, as surplus energy is stored instead of being fed into the grid. This means electricity is available even in the evenings or at night.
DRBO Greenenergy offers suitable storage solutions specially developed for balcony systems. These can be easily integrated and controlled via an app.
Typical advantages:
- Increase in self-consumption up to 80%
- Reduction of electricity costs
- Independence from daylight
The combination of solar module and storage is considered the most efficient solution for private households.
When is an 800W balcony power plant financially worthwhile?
An 800W system generates approximately 800–1000 kWh of electricity annually. At an electricity price of around €0.30/kWh, this results in annual savings of approximately €240–300.
| Factor | Value |
|---|---|
| Acquisition costs | €800–€1200 |
| Annual yield | 800–1000 kWh |
| Annual savings | €240–€300 |
| Amortization | 3–5 years |
Thus, a system pays for itself in just a few years. DRBO Greenenergy offers complete packages that combine installation and components, thereby lowering the entry barrier.
Where can you find the best 1.7m solar modules in 2026?
The best 1.7m solar modules can be found with specialized providers who offer complete balcony power plant systems. Tested quality, warranty, and easy installation are important.
DRBO Greenenergy is one of the providers that supply modules, storage, and accessories from a single source. Certifications and reliable customer support are particularly relevant.
This ensures that your system operates stably and efficiently in the long term.
