Project: Towards an energy-based parameter for photovoltaic classification

Photovoltaics (PV), a method of generating electricity from solar radiation, has been rapidly growing as a viable energy source over the past decade and the PV world market volume is now approximately €50 billion per year. PV devices are currently sold according to their energy output as measured under standard test conditions. These standard test conditions represent climate conditions specific to the USA, which can lead to inaccurate estimates of the energy generated when measured under real operating conditions. Every one per cent uncertainty in energy yield estimation leads to a financial uncertainty of €500 million. This is particularly relevant in Europe where PV systems are operated in a wide range of climatic conditions. This project will develop a new classification system of PV devices based on their energy production under different operational conditions. This will provide reliable data, enabling governments and industry to make informed decisions over which PV technologies are most suitable.
