Sigenergy has entered Europe’s utility-scale photovoltaic market with a major project in Weissach im Tal, Germany, in partnership with PV specialist Arausol and distributor Memodo. The plant, currently under construction, will combine 11.6 MWp of installed solar capacity with 20 MWh of decentralised battery storage using 1,660 Sigenergy battery modules of 12 kWh each.

The system uses direct current coupling, allowing surplus solar power to flow directly into the batteries before conversion to alternating current for grid feed-in. According to the company, this improves overall system efficiency by at least 4 per cent and removes the need for duplicate inverter infrastructure.

Sigenergy said the decentralised SigenStack design also enables faster installation without heavy equipment, while reducing land sealing. Arausol is handling construction and project management, and grid connection is scheduled for July 2026.
