Turnkey Supplier Award
sites Thanks to its global network of engineers and specialists, M+W Group can make available its global know-how to customers when providing modular or turnkey solutions based on fast track schedules, appropriate quality standards and rigorous adherence to the budget.
Technology and System Capability
M+W Group globally covers the complete added value chain for Photovoltaics with consulting, design, construction and project management, from poly silicon plants to cell and module factories as well as PV power plants. The scope includes the turnkey design, build and technical set-up from smaller pilot lines through to large-scale PV plants, be it c-Si or thin film technology.
Currently the scope has been extended to the design of float glass lines with emphasis on the specific requirements of the PV industry. With more than 10 GWp manufacturing capacity designed and built M+W Group is a global market leader in this sector.
With a staff of more than 6,000 people spread throughout five continents. M+W Group is able to keep pace with the clients growth strategies and to offer localized expertise around the world. M+W Group had the honour of providing continuous design/build services and accompanying their PV customers on their way from start-up companies to the top ten list of PV players. The high amount of repeat customers emphasizes clients’ satisfaction with M+W Groups work.
Challenge
The main challenges for high volume PV manufacturing sites are: - Reduced running costs by advanced engineering as well as by energy saving and recycling technologies. - Smart design to ensure minimum investment. - Using a smart logistic concept to reduce working capital. - Fast track approach to reduce time to market. - Meeting and exceeding EHS and quality standards. - Smart phasing concepts towards multiple GW
Problem Solved With its integrated project approach M+Ws best-in-class solutions can solve these challenges: - Comprehensive site selection and site development, including all current and future requirements. - Defining production technology and future expansions. - Defining equipment layout and the logistics concept. - Value engineering and Benchmarking - Final design starts in parallel with issuing the building permit documents - Construction starts depending on partial building permission - Global sourcing and volume purchase agreements reduces costs for hardware - In house engineering for water and chemical recycling/reclaim technologies - Advanced energy supply concepts - Mass and energy flow modelling to reduce overall life cycle costing With its long-term experience M+W Group provides best-in-class solutions with optimum flexibility to future expansions, minimum operating costs and fast time-to-market.
Noteworthy
Based on its 11 years of experience in this market M+W Group operates a comprehensive database with the consumption data of the process equipment with real measured consumption data. This enables the company to benchmark the data provided by equipment suppliers with the real consumption data in the very beginning of the project. With this powerful tool M+W Group can design the utility systems according to the technological requirements of the process tools.
In several PV projects M+W Group has proved that the terms environmentally benign and cost effective are not a contradiction. For example water reclaim or water/chemical recycling provides a significant reduction of running costs for high volume production sites. M+W Group has developed adequate reclaim and recycling systems.
Several of the projects additionally have been designed and executed according to LEED (Leadership in Energy and Environmental Design) standards. The main requirements are: - low iron content for high transmittance of the cover glass - thin glass (2mm) to reduce weight and increase transmittance - specific coatings like ARC (Anti-reflective coatings) and TCO (transparent Conductive Oxide), depending on application. Therefore M+W Group is teaming up with technology partners and offering the design and build of float glass and glass processing lines for the PV industry. Key feature is a smaller float bath with capacities of 120t/day to 200 t/day and customized glass width (e.g. 1.6m) instead of commonly used jumbo glass (3.3m x 6.1m). Such capacities can deliver the glass demand for a 500 MW Thin Film facility.
It is expected that due to the integration and focus on PV specific requirements the cost for glass can be reduced 20% to 30%.
Innovation
The advanced portfolio and the in depth technology know-how as offered by M+W Group for design / build services for the entire PV added value chain from Poly Silicon over glass to PV modules and finally PV power plants makes it possible for our customers to benefit from our experience and use all synergies with regard to energy saving potentials and improved logistics for integrated future PV manufacturing sites in the GW scale. This approach will lead to considerable cost reductions not only in initial investment costs but in longer term running costs as well.
Customer Benefits
The main benefit for customers is that they profit from fast time to market and turnkey-capability due to M+W Groups integrated project approach as well as that M+W Group can offer services for the entire PV added value chain, depending on each customers requirements.
