The available guidance does not establish a universal north-facing or winter output figure. Your balcony’s location, panel direction and tilt, nearby obstructions, and household electricity use all matter, so use a configuration-specific estimate rather than assuming a particular annual yield or payback.
How much do shade and direction affect balcony solar?
Orientation affects annual generation. Germany’s Umweltbundesamt (UBA) says south-facing modules provide the best yields, while east- and west-facing orientations are also possible. East or west may suit a household that uses more electricity in the morning or late afternoon, though actual savings depend on when the system generates and when electricity is used. UBA’s guidance on balcony solar systems does not establish a universal output for every orientation.

Partial shade
A shaded panel can still produce electricity, but UBA warns that even partial shade can significantly reduce generation. The loss depends on where and when shade falls, as well as the site and system; the general guidance does not support one percentage that applies to every balcony. A tree, adjacent building, balcony above, or railing can cast a different shadow through the day and across seasons.

A north-facing panel may produce some electricity, but the reviewed official guidance identifies south as the strongest general orientation and east or west as viable alternatives; it does not quantify north-facing output. It is reasonable to infer that a typical north-facing balcony is a weaker purchase prospect than a comparable south-facing one, but that is not a measured yield prediction. Local surroundings and the panel’s actual direction and tilt still matter.

What changes in winter?
Winter sunlight arrives at a lower angle, and shadows reach farther, reducing the time or area a balcony panel may receive direct sun. Berlin’s Solarcity guidance specifically cautions that winter shadows are longer. A panel receiving light can still generate electricity, but that does not mean winter output will be high.
There are two useful comparisons to keep separate: UBA says a vertically mounted balcony module can perform somewhat better in winter relative to its own summer generation, while still producing less in summer-to-winter comparisons overall; Berlin’s guidance says angling a module about 30 degrees toward the sun can significantly improve yield compared with hanging it vertically. These statements compare different things: seasonal output of a vertical module versus the output of a tilted module. A tilt is only worth considering if the balcony, mounting system, and local rules allow a secure installation.

Combined with a highly durable ETFE laminated case, this design enhances outdoor durability and extends the lifespan of the panels. With an IP65 waterproof rating, they can withstand various weather conditions, ensuring reliability for all your outdoor activities.
How to estimate your own balcony
For a meaningful estimate, record the panel’s location and direction—not just the direction the apartment entrance faces—and map when nearby structures or the balcony above shade the intended panel area. Include possible mounting tilt and consider that winter shadows extend farther. Compare the estimated generation with the household’s electricity use during the production hours: a generation estimate is not automatically an equal amount of bill savings.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
- Enter the location, orientation, tilt, and shade conditions for the intended setup in HTW Berlin’s Plug-in Solar Simulator. The calculator estimates self-supply, solar use, avoided emissions, generation cost, and payback.
- Review the simulator documentation to understand its modeled assumptions, including shade and seasonal effects. Treat the result as a model-based estimate, not a guarantee of on-site performance.
- Check that the kit’s module and inverter, mounting, and electrical connection comply with the rules where you live. Requirements vary by country and, in some cases, by building.
UBA’s 2026 example illustrates why generation and savings should not be conflated: it estimates that 45% of generation, or 240 kWh, could be consumed directly in the home without a battery, and calculates nearly €90 in annual savings using an assumed electricity price of 37 ct/kWh. Those are illustrative figures under the agency’s assumptions—not a forecast for every household, shaded balcony, or north-facing installation.

Is a balcony solar kit worth considering?
A complete balcony solar panel kit typically combines PV module(s), an inverter, cable, and mounting hardware. Before buying, assess whether the intended panel area receives useful light, whether you can mount it safely, and whether your household can use electricity while it is being generated. In Germany, UBA notes that balcony systems may have too little surplus—particularly in winter and shoulder seasons—to make a battery worthwhile for a typical household.
- More promising: the panel can face south, east, or west; it has limited shade; and household electricity use overlaps with generation.
- More uncertain: the panel faces north, is shaded for substantial parts of the day, or is affected by long winter shadows. Use a site-specific estimate before assuming the economics work.
- Not a reason to risk an installation: chasing extra sun with an insecure tilt or fixing. UBA and Berlin’s guidance emphasize secure mounting; wind resistance and balcony suitability matter wherever the system is installed.
German rules are not universal
The following limits and requirements are specific to Germany and should not be applied automatically in other countries. The Bundesnetzagentur describes German plug-in solar systems with limits of 2,000 W installed module power and 800 VA inverter power, alongside registration in the Marktstammdatenregister. Consult the regulator’s balcony solar system guidance for the German context, and check current local requirements wherever you live.

For Germany, UBA discusses product-standard and connection conditions for plug-in systems. It says a Schuko connection is norm-compliant only under stated conditions, including module power no higher than 960 W, compliance with DIN VDE V 0126-95, and additional safeguards; it also says not to use a multiple outlet strip. DKE says DIN VDE V 0126-95, published in December 2025, sets product requirements addressing electric shock, assembly by laypeople, mechanical safety, and overload of household wiring. These details do not make every household outlet or installation safe; check the full current requirements for the actual system and connection.
