++++Press Release from Solar Tower Technologies AG - 1st Heliostat Field in Saudi Arabia commissioned ++++
Starnberg, April 7th, 2015
Solar Tower Technologies (STT) announces the successful commissioning of the very first
heliostat field in Saudi Arabia. The heliostat field consisting of 66 heliostats, 8 m² reflector
area each, has been installed and successfully commissioned within 3 weeks at the solar
tower test site of the King Saud University in Riyadh, Saudi Arabia.
Prof. Dr. Hany Al-Ansary from King Saud University stated: “The heliostats from Solar Tower
Technologies show the high quality we expected to achieve the high level of concentration
required to achieve the targeted high temperatures of more than 700°C in our receiver. Both
the quality of the image and the precision of tracking even at high wind exceed the quality of
heliostats I have seen in other commercial installations.”
“The quality of the components and the robust design of the STT-heliostat has proven to be
the right approach for such an installation” adds Dr. Philipp Schramek, CTO of STT. “The
proprietary heliostat field control system based on a joint development with Bosch Rexroth
allows precise control and calibration of the heliostat field and is suitable for fields with
several thousands of heliostats“
Besides the 8 m² heliostat installed in Riyadh, STT offers as well a 17 m² heliostat for solar
tower plants in MW-range based on the same technology.
Both heliostat technologies and the heliostat field control system are available to interested
parties. For any questions or enquiries, please contact Dr. Philipp Schramek via

++++ Solar Tower Systems GmbH (STS) illuminates a Norwegian community by sun mirrors ++++
Starnberg, October 29th, 2013
Attracted by very great interest in the international media, performance of an innovative mirror system will be launched in this last week of October in Rjukan (Norway). This mirror system supplies the community with reflected sunlight during the dark of winter time. With customized solar mirror technology (Heliostats) the technology company Solar Tower Systems GmbH provides cozy warmth and sunlight onto the main square of the community.
Residents of Rjukan, an industrial town in Norway, have grown accustomed to dark and gloomy winters. Shielded by the Gaustatoppen Mountains, the valley town is cut off from direct sunlight during five to six months of the year. Late last year Solar Tower Systems GmbH was commissioned by the municipality of Rjukan with the design, manufacture and installation of the so-called “Mirror Projects Solspeil ". Thanks to these newly installed mirrors, however, Rjukan will receive sunlight for the first time in the town's more than 100-year history.
On a hillside about 500 meters above the town, an expert team of Solar Tower Systems – with many years of experience in the field of solar thermal power plants, has-installed several heliostats being guided computerized to follow the course of the sun. STS Project Manager Joachim Maass is enthusiastic: We are pleased that our company was selected for the planning and execution of this exciting project. The environmental conditions were very challenging and the design of the overall system is compared to our main business very specific.
Solar Tower Systems GmbH well- known amongst experts for its expertise on heliostat technology, which is usually used for solar thermal power plants in very sunny areas like Arabia, North Africa and Australia.
++++ Solar Tower Systems (STS) installs heliostat system in Rjukan - Norway ++++
Starnberg, July 31st, 2013
The town of Rjukan - Norway suffers from the lack of direct sunshine during the winter period due to the shadow Norway's second largest mountain creates. A heliostat system on the northern hill reflects solar radiation onto the market square. Solar Tower Systems GmbH (STS) has been contracted to carry out the design, manufacturing and installation of the heliostat system which will be commissioned in August 2013.

++++ Solar Tower Systems and Bosch Rexroth make inroads into the CSP industry ++++
Starnberg, September 26th, 2011.
By establishing partnerships and creating specialised industry networks, smaller players are able to enter into the CSP industry and ramp-up a competitive technology.
In the past two years, giant energy companies such as Siemens, GE, Alstom Power and Areva have made giant strides towards success in CSP. Not only has this increased much needed cash flow to the industry but has furthered confidence in CSP for other investors such as banks.
But now it’s not just the big players making the big gains; new smaller entrants have found creative ways to ramp-up their technology. Such is the case of Solar Tower Systems (STS), a German CSP technology company developing products for solar tower plants including heliostat fields, receivers and storage, using the experience of the founder’s team which stretches back to the early days of CSP.
STS focus on their core strength, technology development, and collaborate with experienced industrial companies. With a strong history in the CSP space, Bosch Rexroth has recently partnered with STS for the joint development and commercialisation of heliostat systems.
Joachim Maass, CEO at STS, recently announced the exciting news that STS are developing a technology able to improve the heliostat field performance significantly which could lead to a significant investment saving for the heliostat field. For the company it is vital to keep investing in their R&D activities and to deliver cost-efficient products.
Since vertical integration is not always an option for smaller companies, Maass believes that creating specialised industry networks is an effective way to deliver a competitive technology whilst filling the gaps within the value chain.
Joachim Maass, will present the STS case study at CSP Today Sevilla (5th Concentrated Solar Thermal Power Summit) on November 29-30.
