Intersolar Europe, taking place from 7–9 May 2025 in Munich, is recognised as one of the world’s leading trade fairs for the photovoltaic industry. As a leading provider of industrial connectivity solutions and a pioneer in the development of residential, commercial, and utility-scale photovoltaic applications, Weidmüller will once again showcase its latest solutions and product highlights in Hall B4, Stand 340. Among the highlights are the most compact surge protection device on the market, PV Inline, the PV Next Fireman Switch, as well as PV retrofit combiner boxes and weather stations.
In 2023, lightning and surge damage in Germany reached record levels: insurers paid out around 330 million euros for approximately 220,000 claims. This marks an increase of 80 million euros in total damages compared to the previous year. These alarming figures highlight the importance of relying on dependable surge protection solutions in the photovoltaic sector — such as Weidmüller's PV Inline.
The number of rooftop photovoltaics systems in Germany is constantly growing – and commercial properties and public buildings are no exception. The German Solar Industry Association expects the expansion of solar power systems on company roofs to grow by around 25 % - including outstanding late registrations (3.6 GW).1This is a continuing trend, and is being accelerated by the requirements of the European Green Deal as well as companies and organisations interested in minimising energy costs and bringing energy-neutral products onto the market. There are a lot of regulations and recommendations to take into account when planning and installing PV systems, including lightning and surge protection and the safety of firefighters in case of fire. Weidmüller has developed particularly compact products for this purpose, offering an extensive product line that includes the right solution for every installation.
Photovoltaic systems are a key component of the energy transition. To unlock the full potential of these systems, accurate monitoring and a robust data foundation are essential. Retrofit solutions for string monitoring and PV weather stations enable existing ground-mounted PV installations to operate more efficiently, significantly improving their economic viability.
