Does a balcony power station make sense in winter? In the dark season this initially seems paradoxical, but the energy yield can be surprisingly high.
In the dark and cold season a balcony power station is certainly not as productive as in the summer months with many hours of sunshine. However, a balcony power station can cover part of your energy needs even in winter. If you follow some tips and adjust your expectations, you can get the most out of your system even in the winter months. Let’s show how it works.
The power plant on the balcony in winter
The fact is that every ray of sunshine reduces your electricity bill and this can be especially beneficial in the expensive winter months. Anyone who is thinking of buying a balcony power station and wants to have an acceptable electricity output in winter should take a close look at the dimensions and performance. The supplier Kleines Kraftwerk offers a complete set with two double-sided XL modules which, according to the manufacturer, deliver up to 1,250 watts peak. During Advent there is a discount of up to 30% and shipping is currently free.
How productive is a balcony power station in winter?
The fact that a balcony power station is only really efficient in summer is only partly true. Of course, more hours of sunshine also means higher yields. However, studies and tests have shown that cooler temperatures can actually be beneficial for solar modules. According to experts such as Solaranlage-Ratgeber.de, the modules work even more efficiently in cold, clear weather. The yield can also be increased with reflective snow, as this increases the light. Double-sided modules especially benefit from this, as they can also produce electricity on the back.
All this does not mean that a balcony power station in winter can equal the power in summer, but electricity is still produced. According to NTV and Solarenergie.de in winter, depending on the weather conditions, an average of around a quarter to a third can still be expected.
These factors have a positive effect on efficiency in winter:
- Clear paradise: Better sunlight on clear days
- Cooler temperatures: greater efficiency of the solar modules possible with the same solar radiation
- Snow: The white, reflective surface of snow can increase energy production
Economical and high-performance balcony control units are available on Ebay, with the discount code CHRISTMAS24 There is also a small discount there.
Yield in winter – then it becomes larger
Especially in the winter months, the larger and more powerful a balcony power plant is, the greater the electricity production, even if the sun does not shine all day. Large mini-photovoltaic systems with four or more modules are becoming more and more efficient: if you have the space, you can maximize electricity production even in the dark season. If the balcony is not large enough for four modules, the XL modules are a good alternative. These offer better performance than their smaller counterparts thanks to a larger overall area. This means you can get more out of a set of two XL modules. Other factors for improving performance include bifacial backs and innovative TOPCon cells which, according to Fraunhofer ISE, have better conductivity than, for example, PERC modules.
Kleines Kraftwerk offers a package with four double-sided XL modules with TopCon technology, which, according to the manufacturer, can each reach a peak of 500 to 625 watts. This set is also currently about 30% off and shipping is free.
Optimize the balcony power plant in winter
In addition to size and performance, there are some other features that allow you to make the most of your balcony power station in winter. It is logical that light output is minimal if the module is covered by a layer of snow or ice. For this reason, thick layers of snow and ice cannot accumulate on the surface of the module and must be removed regularly. But the correct inclination angle also plays an important role: in winter it should be steeper to optimally capture the low sun.
- Remove snow and ice regularly: Free modules absorb more sunlight, even ice can damage the module surfaces
- Align the modules optimally: A steeper angle in winter allows for maximum sunlight
- Keep forms clean: Even in winter it is advisable to regularly clean the modules of dirt to make them more efficient
Media Markt is offering a double-sided balcony power station from Solakon with two solar modules with a total output of up to 1,170 Watts at a 58% discount.
Conclusion
A balcony power station can also help in winter to reduce the electricity bill, which is often much higher in the dark season. If you want to buy a balcony power station in winter, you should pay attention to a few things: Larger XL modules and newer technologies provide more power, and double-sided solar modules also benefit from reflective snow. Furthermore, the modules should always be kept clean and free of snow and in winter the angle should be slightly steeper than in summer. If you take all this into account, even in winter electricity production can contribute to your electricity bill.
