Company expands product lineup with high-efficiency solar technology and integrated storage solutions to meet global demand for renewable energy systems

HAMBURG, Germany – Nov. 7, 2025 – Kosol Energie, a prominent innovator in solar technology, announced today the launch of its new 730 Wp G12 TOPCon solar panel with enhanced efficiency and maximum power output. In conjunction, the company announced it will also begin production of battery energy storage systems (BESS) in a strategic expansion and provide end-to-end clean energy solutions.

This dual announcement is happening at a moment when worldwide demand for high-performance solar components and energy storage is increasing, especially as the overseas energy storage market continues to grow. According to industry data, the scale of energy storage projects under construction or in development overseas reached approximately 13.7 GW/60.8 GWh in the first half of 2025, highlighting the critical need for integrated solar and storage solutions .

Revolutionizing Solar Efficiency with G12 TOPCon Technology

Kosol Energie’s new 730 Wp panel leverages advanced G12 silicon wafer technology and TOPCon (Tunnel Oxide Passivated Contact) cell architecture to achieve a remarkable conversion efficiency of up to 23.3%. This places it at the forefront of the commercial solar panel market .

The solid construction of the panel guarantees durability in varied environmental conditions, with an operational temperature range of -40°C to 85°C and maximum system voltage of DC 1500V too. Coupled with all of these characteristics, it makes it suitable for large utility applications, commercial installations and for use in demanding residential applications where energy yield and space efficiency are critical.

The industry is increasingly adopting TOPCon technology for its superior efficiency and performance. For instance, a major Indian manufacturer recently secured a large order for N-type TOPCon modules, underscoring the global shift towards this advanced cell architecture .

Strategic Expansion into Battery Energy Storage Systems (BESS)

Kosol Energie is well aware that the future of energy is integration; The company is expanding its manufacturing capabilities to include Battery Energy Storage Systems and will be in a position to offer the full integration of solar generation and storage, which will further allow customers to maximize their self-consumption of solar power, improve grid stability, and backup power systems.

The company’s entry into the BESS market is timely. The global push for large-scale storage is evident, with projects like a 2.5GW/10GWh grid-scale BESS in Saudi Arabia and a 300MW/1200MWh project in the Netherlands moving forward . Kosol Energie aims to serve this growing market with modular, scalable storage solutions designed for both residential and commercial use.

Driving the Global Transition to Clean Energy

Kosol Energie is implementing a dual strategy of encouraging solar panel innovation and moving into storage production to combat an issue that has plagued the renewable energy industry for many years: intermittency. The new offering of high-efficiency solar panels combined with a dependable energy storage system provides businesses and homeowners the ability to reduce their reliance on the electric grid while reducing their carbon footprint.

“The combination of high-efficiency solar generation, then matching it with intelligent storage to meet energy demand, is the foundation for a decarbonized energy future,” a spokesperson for the company stated. “Our new 730 Wp panel produces more energy, and the BESS product means that energy will be available when and where it is most needed, day or night.”

Availability and Future Outlook

The new 730 Wp G12 TOPCon solar panel is set to be shipped out to distributors and large-scale project representatives in Q1 of 2026. Kosol Energy’s first series of modular BESS units will also begin pilot testing with a limited number of partners during the same timeframe.

Kosol Energie is having conversations with potential technology partners and manufacturers to assist with scaling production of its BESS assembly line, with a focus on new advancements in both battery chemistry and system integration.
