SolarWorld has once again set itself apart from the multitudes of solar technology manufacturers this year. At the Intersolar trade show from June 13 to 16 in Munich, the company exclusively presents new technologies that make products from Germany’s best-known solar brand even more effective. The technologies increase the efficiencies of polycrystalline and monocrystalline solar modules “Made in Germany” and “Made in USA” by an average of 5 percent to 10 percent. The high-performance modules will be available in the second half of the year.
“Our researchers have managed to introduce a variety of new technologies into our automated solar cell production and combine them to create a better module while cutting costs,” says Frank Asbeck, CEO of SolarWorld AG. Three aspects played a role in improving the processes. First, SolarWorld is one of the world’s first manufacturers to significantly reduce the width of the electric conductor strips on the solar cells. Using an in-house technology, they achieve better results in comparison to industry standards of 80 to 90 micrometers. Second, SolarWorld uses a selective emitter on the front of the cell, which makes more light available for conversion into electricity. Finally, the back of the monocrystalline cell has been modified to increase electric conductivity.
The high efficiency and quality of solar power modules also determine the standards of other components. This year, interest among attendees will focus on solar power storage in addition to mounting technology. SolarWorld has offered a full battery system since early 2011, making it the first manufacturer in the world to do so. Now, SolarWorld is leading the way into the future. The new SunPac K 10.9 system is the first to integrate charging and discharging functions into a three-phase storage inverter. The system increases efficiency while eliminating the need for an additional charge controller. This flexible system makes it possible to operate the solar power system with or without storage and to retrofit it with a first- or second-generation battery, as needed.
One very special guest at the trade show booth is sure to attract a lot of attention. The SolarWorld GT solar car is making a pit stop in Munich just in time for Intersolar. Students at Bochum University of Applied Sciences developed the solar-powered Gran Turismo, sponsored by SolarWorld, and embarked on a trip around the world, departing from Australia last year. The aim is to be back in Australia in November, securing the world record: once around the world powered only by the sun.
