The present paper highlights the results obtained during the development of two European research projects within the FP7 for the optimization of the environmental performance of PV systems: “LCA to go” and “ZeroWIN”. ZeroWIN defines strategies for the prevention of waste and the carbon footprint based on industrial symbiosis. These strategies were implemented in two PV systems. Additionally, the LCA to go project is developing a free, user-friendly web based tool in order to disseminate the idea of LCA among SMEs. Currently the beta version of the tool is available at [lcatogo.simpple.com]. The tool enables the comparison and evaluation of different types of installations showing the choices’ impacts on relevant environmental indicators for the PV sector. The LCA to go tool developed for PV was used to implement an Environmental Product Declaration (verified by Fraunhofer IZM) for one of the PV system implemented during the ZeroWIN project. The final results showed that the Embodied greenhouse gas emissions are 4.377,5 kg CO2-eq and its energy payback time is 2.2 years. They also showed that the emissions associated to the electricity generated are 74% less than the emissions associated to the same electricity if consumed directly from the grid in Spain.
