For a number of years, balcony power plants, also known as mini PV systems, have been a popular way to generate environmentally friendly electricity and save money. A frequently asked question is whether a balcony solar system with an output of 800 watts is permitted. In this blog article we will deal with the new regulations proposed by the Association for Electrical, Electronic & Information Technologies (VDE).
Previous regulations
Up until now, balcony solar systems have been permitted in Germany with a power output of up to 600 watts. This regulation has been in effect since 2012 and is based on the so-called "socket regulation". The mini PV system is simply plugged into the socket and the electricity generated is fed directly into the power grid. However, there are some conditions that must be met. For example, the system must be approved by the grid operator and there must be no repercussions on the electricity grid.
New proposals from the VDE
The VDE is now proposing to increase the power limit for balcony solar systems to 800 watts. The goal is to create more incentives for the use of renewable energies and to promote the energy transition. The mini-PV systems should still be able to be simply plugged into the socket and not require any special installation.
However, there are also concerns that increasing the power limit could cause problems. For example, there could be repercussions on the electricity grid if too many systems feed in electricity at the same time. The VDE therefore proposes that in future the mini-PV systems be equipped with an automatic switch-off device that prevents too much electricity from being fed into the grid. In addition, in future the systems should only be allowed to be installed by specialists in order to increase safety.
Conclusion
Increasing the output limit for balcony solar systems to 800 watts could help produce more renewable energy and drive the energy transition. However, grid impact and safety concerns must also be addressed. VDE's new proposals, an automatic shut-off device and professional installation, could help alleviate these concerns. It remains to be seen whether the new regulations will be implemented and what impact they will have on the spread of balcony solar systems.
