SolarWorld AG consistently strengthens its business with solar modules and complete systems. At the Intersolar North America taking place in San Francisco from 15 to 17 July 2008 the company announced the completion of its new fully automatic production line for mono-crystalline solar modules in Camarillo with an output capacity of 100 MW. 'With this we will meet the booming demand for high-quality solar systems in the USA', explained Dipl.-Ing. Frank H. Asbeck, Chairman and CEO of SolarWorld AG, when he visited the exhibition. 'Especially in California the solar market is growing rapidly. Solar power from the roof will be cheaper than conventional peak-load power in a few years time'. The Intersolar North America is part of the leading US semiconductor fair Semicon West and is the largest US solar show next to the 'Solarpower' exhibition. SolarWorld No.1 to start in the North American Solar Challenge

Just a few days before the beginning of the exhibition the solar racing car SolarWorld No.1 entered the biggest North American race of solar motor sports, the North American Solar Challenge, in Dallas. The team from the University of Bochum which developed the solar racer in cooperation with the main sponsor, SolarWorld AG, has been on the race track since Sunday bearing the Number 1. The route will take the race cars 4,000 kilometers across the North American continent from Texas to Calgary in Canada. It is expected that the contestants will cross the finishing line on 22 July 2008. The solar racing cars of the 24 teams who mainly come from US universities are exclusively powered by the energy of the sun. 'Now that the team has again optimized the technology I am confident that the SolarWorld No.1 racer will improve upon the fourth place it achieved in its last race in Australia', said SolarWorld chief Frank Asbeck. In the World Solar Challenge covering 3,000 kilometers across the Australian continent in the fall of 2007 SolarWorld No.1 had won the prize for the best design. The aerodynamic racing car weighs 200 kilograms, is propelled by highly efficient solar cells with a surface of six square meters and reaches a top speed of 120 km/h. SolarWorld AG's sponsorship for solar motor racing is designed to make the public aware of the potentials of modern solar power technology and at the same time to promote the development of young engineers and to alert them to the future tasks of climate-friendly energy generation.
