TubeSolar AG and sbp sonne develop innovative agricultural land spanning system -
Worldwide Partnership with Stuttgart based Engineering Office sbp sonne

Augsburg, 6 August 2020 - TubeSolar AG (ISIN DE000A2PXQD4, Düsseldorf Stock Exchange), manufacturer of innovative robust thin-film tubes for solar energy generation with a focus on applications in agriculture (agricultural photovoltaics), has entered into a global partnership with renowned engineering office schlaich bergermann partner - sbp sonne gmbh from Stuttgart. Together with sbp's expertise for efficient constructions for solar systems, a cost-effective and environmentally friendly form of power for the TubeSolar modules is to be brought to market. By roofing agricultural grounds, these can be used for both agriculture- as well as for solar energy production. This presents a double source of income. An area of one hectare (100x100 meters) allows for electricity generation of approximately one megawatt.

These technical solutions are technologically very demanding. To protect the soil, the use of concrete foundations and solid steel girders is completely foregone. The steel cable construction above the agricultural grounds must, among other things, be easily installable at heights of 4 to 10 meters, be able to span up to 50 hectares, withstand extreme wind forces and high-weight loads, be compatible with fully-automatic cleaning, and guarantee optimal plant growth by accurately calculating the amount of sunlight reaching the ground.

Through innovative solar projects throughout the world, sbp sonne has demonstrated that it can develop intelligent, cost-effective solutions for solar thermal and photovoltaic power plants whilst meeting the highest standards. Through the development of components and systems for solar power technology, sbp has established a solid reputation in the field of solar energy for over 30 years and is considered a leading international engineering firm. TubeSolar AG has agreed a worldwide partnership with sbp for the realization of the construction of its spanning system, including software development for light detection and fully automatic cleaning systems. The partnership agreement is designed as a licensing model.

Jürgen Gallina, Chief Technology Officer (CTO) of TubeSolar AG: "With our thin-film photovoltaic modules, which we assemble from glass tubes, we are technologically well on the way to scaling up the existing pilot production to an annual production capacity of 250 MW in the coming years. The innovative elevation of our modules above agricultural areas is another unique selling point of TubeSolar AG. With the expected technical solution from sbp, we will reach another milestone in our pursuit of becoming a large-scale agricultural photovoltaics provider".

Markus Balz, Managing Partner of sbp sonne commented: "TubeSolar's approach is innovative and presents an important solution to the increasing demand for solar energy while simultaneously reducing CO2 emissions. It also introduces the dual use of open spaces. For us, this is a very exciting task that we are happy to solve. We intend to present the first results by the end of 2020."

About TubeSolar AG (www.tubesolar.de)
As a spin-off, TubeSolar AG has taken over the laboratory production including patents from OSRAM/LEDVANCE in Augsburg and has been using this patented technology since 2019 to manufacture photovoltaic thin-film tubes that are assembled into modules. These have considerable advantages over silicon solar modules in terms of weight, geometry, material use, yield, long-term stability and recycling. The technology is to be used primarily in the agricultural sector and will span agricultural production areas. In the next few years, it is planned to expand production in Augsburg to an annual production capacity of 250 MW.
