Many balcony solar systems lose a lot of power in the shade. This is shown by a recent study by Stiftung Warentest. Of eight systems tested, none generated electricity when partially covered. Only one system achieved an overall rating of \"good\". There were problems not only with performance under sub-optimal conditions, but also with the inclination of the panels and stability under load, for example with snow. Such loads caused some panels to break.<\/p>\n
Another point of criticism concerns the inverters sold with the systems. These devices, which are essential for converting direct current into alternating current, sometimes caused serious electromagnetic interference that could even affect police and emergency services radio networks. In one case, the product was even temporarily withdrawn from the market, albeit without a right of exchange for buyers. Alternatively, affected inverters can be replaced, which incurs additional costs.<\/p>\n
Despite the technical challenges that can be associated with balcony solar systems, they are an accessible option for many to produce their own electricity and save energy costs in the long term. Anyone interested in such a system should thoroughly check the individual suitability and efficiency and can estimate the potential benefits and savings using online simulators such as the \"Plug Solar Simulator\".
