Tubesolar AG — Investor Relations & Filings
Tubesolar AG was a technology company that developed and manufactured patented photovoltaic (PV) thin-film tubes. A spin-off from OSRAM/LEDVANCE, the company's core product was a tubular solar module designed to enable the dual use of land for both agriculture and solar energy generation (agrivoltaics). The technology allowed light and precipitation to reach crops beneath the installation while producing power. Beyond its primary focus on the agricultural sector, applications were also explored for solar parks and building-integrated systems such as green roofs. The company ceased business operations in August 2023.
