With PV module prices having come down dramatically over the past 3-5 years,many countries have now reached"grid parity"or have introduced feed-in tariffs to accelerate the path towards it.This in turn has spurred an explosive growth of PV deployment in some countries,with many others following at a similar pace.However,despite this fundamentally positive trend,the current speed of deployment raises concerns with governments,utilities and investors alike.Solar PV systems are supposed to last for a minimum of 20-25 years.However,they will only do so if the quality of the system design and implementation lives up to the warranties given on the PV modules.Experiences from Europe show that the majority of the system failures that occurred in the past arose indeed from poor design and implementation.Beyond the PV system itself,one of the major concerns for utilities is the uncontrolled project development that often takes place without proper analysis and planning about where large-scale PV system installations should be allowed in the first place-given the variable nature of the solar electricity generation.Multi-dimensional regional analysis techniques that take into account the structure of the electric power grid and the locations of the generators and load centers,as well as the available solar resources can prevent that and,furthermore,enable the optimum siting of solar PV systems to support the power grid rather than running the risk of compromising its resilience.This presentation will give an overview of how PV system planning and implementation should be carried out in a holistic way,properly involving all relevant stakeholders from investors via utilities to governments.
