In the countries of the European Union, devices up to a power of 600-800 watts typically do not need to be licensed.
In Germany, two commercial big guns have already entered the balcony solar market: Lidl started selling solar panels last week, and one of its biggest rivals, Aldi Nord, will start selling them from June, reports G7. The balcony solar panel can be plugged into the outlet in the apartment at home. If the sun shines on the panel, which is typically attached to the balcony railing, then the generated electricity can be used by the equipment of the apartment, thus reducing the electricity bill.
In the countries of the European Union, devices up to a power of 600-800 watts typically do not need to be licensed, only declared. In contrast, their use is illegal in Hungary. The G7 notes in its article: since there is serious interest in the product, and control can be quite difficult in practice, there is a danger that a unique gray zone will develop from private imports in Europe.
Lidl’s balcony solar panel available in Germany costs 219 euros (82,000 HUF at the exchange rate at the time of writing) and has a nominal power of 150 watts.
