While the energy transition is sometimes disparaged in political discussions, optimism and a focus on the future characterized this year’s The smarter E Europe. Although the visitor and exhibitor records set in 2024 were not quite broken, the rear halls of the Munich exhibition center were at times almost impassable between May 7 and 9. 2,737 companies and organizations from 57 countries presented their new products and services, attracting around 107,000 trade visitors from 157 countries. With more than 2,600 participants, the accompanying conferences and side events also met with great interest.
“Accelerating Integrated Energy Solutions” was the motto of this year’s The smarter E Europe with its four trade fairs Intersolar Europe, ees Europe, Power2Drive Europe, and EM-Power Europe. With the global expansion of renewable energies in full swing, the challenge now is to make the energy system more flexible, digital, and integrative. “The smarter E Europe was once again the blueprint for the climate-neutral energy world of the future,” said Markus Elsässer from organizer Solar Promotion. “The technologies and solutions are available. Now it’s a matter of continuing along this path with determination.”
Latest market figures presented
The trend toward integrating photovoltaics into the energy system for a stable, affordable, and secure energy supply around the clock was evident not only in the products on display, but also in the latest market figures presented by industry associations SolarPower Europe and BSW-Solar. In addition to photovoltaics, battery storage is also growing strongly. The European storage market is expected to grow by 36 percent to 29.7 gigawatt hours this year, with large-scale storage accounting for 55 percent of this growth. Photovoltaic expansion in Europe is expected to grow slightly by 3 percent to 84.7 gigawatts of installed capacity this year. Larger commercial rooftop systems and solar parks are becoming increasingly important, as is the marketing of electricity via power purchase agreements.
However, Joachim Goldbeck, CEO of BSW-Solar, sees one challenge in adapting the regulatory framework so that the grid-integrated expansion of electricity storage facilities can be driven forward even more quickly, whether through privileges in building law or a reform of grid fees. He also sees differing national regulations, for example in labor law or the establishment of company branches, as an obstacle to a Europe-wide energy transition, as these make cross-border activities very difficult, even for solar companies.
Booming cominbation of PV, storage and energy management
Dimitris Galanos, Key Account Manager Greece at Sungrow, was optimistic. The combination of photovoltaics and large-scale storage is booming in Greece and is also being promoted through tenders. Sungrow has already supplied inverters and batteries for projects with a capacity of over 4 gigawatts and expects this figure to double in the coming years.
Pol Spronck, EU Sales Director at myenergi, also sees the increasing use of batteries and energy management systems to balance generation and consumption as an opportunity to stabilize the grid. The Dutch company presented new solutions for private households and businesses in Munich, including energy distributors, energy sensors, smart wall boxes, and a user-friendly app.

Spanish battery manufacturer Cegasa showcased its modular and scalable storage solutions for residential, C&I, and utility-scale applications. Dyness (China) also showcased versatile modular battery storage systems for private and commercial applications. In addition to inverters and storage systems in all sizes, Sungrow presented fast charging solutions for commercial electric vehicle fleets and, for the first time, the iHome Manager, an energy management system for households.
Hot topic cybersecurity
Cybersecurity is becoming increasingly important for controllable devices such as inverters and batteries. “Cybersecurity plays a crucial role for us when it comes to the development and use of our products,” says Quirin Löffelmeier, Senior PR Manager Europe at Sungrow. The company has the relevant certifications, complies with relevant regulations such as the EU General Data Protection Regulation (GDPR) and operates servers in Germany for its European business. Claire Gardner, Marketing Manager Europe at Chinese inverter manufacturer Solis (Ginlong), expressed a similar view.
Goldbeck Solar presented a new cybersecurity system in Munich that is designed to reliably protect large solar installations from hacker attacks and digital threats. It is based on intelligent hardware combined with permanent interface testing, continuous monitoring of internal network anomalies, and regular identification of vulnerabilities in the network. “It is important to protect not only individual components such as inverters, but entire systems,” emphasizes Sergey Bruch, Head of IT Infrastructure and Cybersecurity at Goldbeck Solar.
Advanced weather forecasting solutions
In times of increasing storms and hail events, weather forecasting systems that are as accurate as possible, such as those offered by Vaisala, are becoming increasingly important for plant operators. As a precautionary measure, tracking systems can then be laid flat to minimize wind resistance, according to Rémy Parmentier, Head of Solar and Hybrid at the Finnish company.

Vaisala presented its advanced weather forecasting systems and weather stations.
The Hail Alert Response System from Array Technologies uses sophisticated weather forecasting algorithms to preventively retract solar trackers about 30 minutes before a predicted hail event, as Aaron Gabelnick explained. The US company, which acquired Spanish solar tracker manufacturer STI Norland three years ago, also has production facilities in Spain. Among other things, it presented its OmniTrack, which can be flexibly adapted to hilly terrain, thus minimizing the amount of groundwork required.
Advanced solar modules
Advanced solar modules also took up a lot of space in Munich. In addition to higher power output and durability, weight is often a factor, especially for large commercial and logistics roofs. Among others, Heliup from France showcased its frameless Stykon lightweight modules, which weigh less than 5 kilograms per square meter, 60 percent less than conventional modules, and can be easily and quickly glued in place. They have an efficiency rating of 19 percent and are manufactured near Grenoble. Annual capacity currently stands at 100 megawatts. According to CEO Yannick Veschetti, the next step is to achieve a module efficiency of 21 percent and expand production.

DAS Solar showcased its entire range of modules, from lightweight modules (efficiency 21,7 percent) and dirt-repellent modules to Topcon back-contact modules with an efficiency of 24.8 percent.
3-gigawatt module factory in France
The Chinese manufacturer is currently building a production facility for n-type TopCon modules with an annual capacity of 3 gigawatts in the Montbéliard region of eastern France. The ground-breaking ceremony for the conversion of an existing factory took place recently. Production is scheduled to start in spring 2026, according to Alden Lee, General Manager of DAS Solar France. 300 employees are to be hired.
Lee expects the “made in France” modules to have manufacturing costs per watt that are around 5 cents higher than in China. There are also plans to set up cell production with an annual capacity of 3 gigawatts. However, until the EU’s planned subsidies for modules with European cells are implemented, the cells will be supplied from the company’s main plant in China. (hcn)

Until 9 May, 2,737 exhibitors from 57 countries will be presenting their solutions, applications and business models for a renewable 24/7 energy supply. Highlights include large-scale storage systems, PV hybrid power plants, bidirectional charging solutions, intelligent load management system and more.
Over 100,000 visitors from around 170 countries are expected to attend the event over the coming three days. One key takeaway from this year’s The smarter E Europe is that the technologies exist, the business models have been tried and tested, and the industry is ready. What we need now is the political will, assertive action and courage to rethink our energy system.
Next step of the energy transition
According to Walburga Hemetsberger, CEO of SolarPower Europe, the European industry association, renewable energies – and photovoltaics in particular – are the key to energy security and economic resilience. Following the extensive deployment of renewable power generation capacities, the focus must now shift to the next step of the energy transition.
“In a world gripped by geopolitical turmoil, one thing is clear: renewables and especially solar PV are key to energy security and economic resilience. Solar power is local, affordable, and clean. To truly future proof our energy system we need stronger grids, smarter flexibility, and full-scale electrification of industry, transport, and heating. Battery storage is no longer optional – it is essential to tackle curtailment and negative pricing. The payoff? Lower costs, cheaper electricity for consumers, more energy security for Europe. The time to accelerate is now.”
The unrivaled affordability of photovoltaic electricity
Recent market figures make it clear: According to Fraunhofer ISE, the production costs of power from large-scale PV plants in Germany were between 4 and 7 euro cents/kWh in 2024, while PV plants with battery storage had production costs ranging from 6 to 11 euro cents/kWh. In comparison, conventional power plants are far more expensive – coal- and gas-fired plants cost between 15 and nearly 33 euro cents/kWh, while nuclear energy is even more costly, with production reaching up to 49 euro cents/kWh. Given these figures, it’s clear that climate-neutral electricity is on the path to success.
We now need to think and act strategically
During the opening of The smarter E Europe, Michael Villa, Executive Director at smartEn – Smart Energy Europe, urged EU representatives to think and act strategically. “In the current geopolitical situation, affordable energy, the competitiveness of our industry and energy security must be the EU’s top priorities. To achieve these aims, the renewable energies industry needs to make a strong contribution by creating demand-side flexibility. However, there are still considerable hurdles to be overcome in EU member states. It is indispensable to enable digitally driven business models to operate and scale within a market-based framework. This is a strategic opportunity the EU must not miss.”
The energy transition is all about flexibility
With the global rise in renewable energy adoption, it is becoming increasingly clear that we need to rethink how our energy system works – making it smarter, more flexible and better connected. In this context, battery storage systems are the backbone of the transformation. They make the grid more stable, enable new business models and boost supply security. Electromobility also has a role to play: Thanks to bidirectional charging, car batteries can be used as decentralised storage devices. This approach has already proven successful in some pilot projects, such as one in France. The smarter E Europe 2025 builds on this promising innovative spark by showcasing the potential of bidirectional charging for a renewable 24/7 energy supply in a dedicated special exhibit (hall C6, booth C6.450).
