The objective of IEA PVPS Task 10 is to enhance the opportunities for wide-scale, solution-oriented application of photovoltaic (PV) power electricity production in the urban environment as part of an integrated approach that maximises building energy efficiency and solar thermal and photovoltaic usage. Value analysis, policy incentives, analysis tools as well as system design and integration that have proven successful in the IEA PVPS participating countries have be developed to the extent possible into a uniform international set of tools for the global market. EU PV-UP Scale has complimentary aims and targets large-scale implementation of PV in European cities. Its main objectives are to engage urban planners, construction and building industry, utility and related stakeholders to identify key economical drivers, bottlenecks such as grid integration issues, and opportunities and barriers within the PV-urban planning process. This Paper discusses the objectives, deliverables from the programs and future challenges for the continued application of PV in urban environments.
