Balcony power plants empower you with a degree of energy self-sufficiency, reducing reliance on the grid. This autonomy is particularly valuable during power outages or in areas with unreliable electricity supplies.

The integration of energy storage solutions takes this independence to the next level. A balcony power plant with storage capabilities can store excess energy produced during peak sunlight hours. This stored energy can then be utilized during the night or on cloudy days, ensuring a constant power supply and maximizing the use of generated solar energy.

Space Efficiency

Urban living often comes with the challenge of limited space, making traditional ground-mounted solar panels an impractical choice for many. Balcony power plants circumvent this issue by making efficient use of available balcony space. This not only optimizes underutilized areas but also opens up the benefits of solar power to apartment dwellers and those without access to a traditional roof.

Factors That Affect How Much Electricity Is Generated by Balcony Power Plants

Harnessing solar power from a balcony setting presents unique challenges and opportunities. The amount of electricity generated by balcony power plants is influenced by the following factors:

Location and Assembly

The geographical location of your balcony power plant significantly impacts its electricity generation capacity. Factors such as local climate, the average number of sunny days, and even air pollution levels can affect solar panel performance. Southern regions in Germany, experiencing longer daylight hours and higher solar irradiance, naturally facilitate higher energy production.

Shadows cast by nearby buildings, trees, or other obstacles can significantly reduce the power output of your balcony power plant. Careful consideration of your balcony's location and the potential for shadowing at different times of the day and year is essential for minimizing this impact.


Achieving a level of self-sufficiency with a balcony power plant often depends on matching the system's energy production with the household's energy consumption patterns. Integrating energy storage solutions, as mentioned earlier, can significantly enhance self-sufficiency, allowing for energy usage during periods of low sunlight. The capacity to store excess energy for later use ensures a consistent and reliable power supply, making your home less dependent on the grid and more resilient to power fluctuations and outages.

Module Orientation

The orientation of solar panels is another critical factor affecting the efficiency of balcony power plants. Panels should ideally face a direction that receives the most sunlight throughout the day. In Germany, south-facing installations tend to harvest the maximum amount of solar energy.

The tilt angle of the panels also influences their ability to capture sunlight effectively. Adjusting the tilt to match the latitude of your location can significantly enhance solar absorption and, consequently, electricity generation.

Steps to Calculate Power Generation of Balcony Power Plant

Calculating the power generation of a balcony power plant is essential for understanding its potential contribution to your household energy needs and for optimizing its efficiency. Let's dive into the process:

Step 1: Determine Your Solar Panels' Wattage

The first step is to identify the wattage of the solar panels you plan to install or have installed on your balcony. As the new law has increased the output power limit of plug-in balcony power plants from 600W to 800W since 2024, your system can either have a peak output of 600W or 800W. This is the maximum power your system can generate under optimal conditions per hour.

Step 2: Determine Peak Sun Hours

Peak sun hours refer to the average number of hours per day when the sunlight intensity is at its peak. Typically, Germany averages about 4 to 5 peak sun hours daily, with the potential for higher values in sunnier southern regions during summer. Use precise local solar irradiance data, like the Deutscher Wetterdienst, to find accurate figures for your area.

Step 3: Calculate Daily Power Generation

Multiply the wattage of your solar panels by the peak sun hours to get an estimate of daily power generation (in watt-hours) of your balcony power plant. You can use this balcony power plant yield calculator formula:

Daily Power Generation = System Wattage × Peak Sun Hours

Take the Anker SOLIX balcony power plant with 800W peak output as an example. Assuming 5 peak sun hours per day, the calculation goes like this:

Daily Power Generation = 800W × 5 hours = 4,000Wh (4kWh)

Based on the calculation, the balcony power plant with the maximum allowed wattage of 800W and 5 peak sun hours per day will generate approximately 4kWh of electricity.

Step 4: Calculate Monthly and Yearly Generation

For a comprehensive view, multiply the estimated daily power generation by the number of days per month for a monthly estimate and by 365 for an annual estimate. This calculation will help you understand your balcony power plant's potential output over longer periods, accounting for seasonal variations in sunlight exposure.

Applying the solar calculator of balcony power plant for an estimated yearly generation:

Estimated Yearly Generation = 4kWh × 365 = 1460 kWh

Estimation of Actual Daily Power Generation

While theoretical calculations give us a good starting point, estimating the actual daily power generation of a balcony power plant requires considering real-world variables. Here's how you can get a more accurate estimate of your balcony solar system's daily power generation:

Understand the Impact of Weather Conditions

Weather plays a pivotal role in the performance of solar panels. Cloudy days, seasonal variations in sunlight intensity, and unexpected weather patterns can all affect how much power your system generates. Monitoring weather forecasts and historical weather data in your area can help you adjust your expectations for daily power generation accordingly.

Account for Panel Orientation and Tilt

The orientation and tilt of your solar panels relative to the sun significantly influence their efficiency. Optimal alignment to the sun's path increases exposure and power generation. While theoretical calculations may assume ideal conditions, adjusting for the actual setup of your panels provides a more realistic estimate of daily power generation.

Use a Solar Monitoring System

Many modern balcony power plants come with monitoring systems that provide real-time data on energy production. The Anker SOLIX balcony power plant with storage for example, comes with an intuitive Anker app that allows you to effortlessly track the real-time energy production and consumption of your system. This data not only offers insights into your system's performance but also helps you identify patterns and potential areas for optimization.
