An environmental Life Cycle Assessment has been conducted for standard and advanced produc-tion technologies for multicrystalline silicon module production and new BOS concepts. It was found that the production route based on Solsilc silicon feedstock and RGS wafer technology can yield a 50% reduction of the environmental impacts in comparison with present-day standard technology. Similar results were obtained for a process using Bayer/Deutsche Solar feedstock material and EFG ribbon technology. New BOS concepts can also help to reduce environmental impacts especially if they allow the use of frameless modules. With such new technologies life-cycle greenhouse gas emissions of PV systems in Southern-Europe can be...
For grading different types of renewable energy based electricity generation systems, a figure of merit has been proposed and evaluated. The figure of merit has been obtained by analyzing total energy utilization in constructing and installing the systems and by their respective electricity generation. The gross carbon emission has also been estimated for evaluation of figure of merit. This figure of merit clearly indicates that wind power is the most sustainable source for electricity generation, followed by small hydropower and solar photovoltaics.
