Spectral irradiance measurements for photovoltaic systems in maritime climates

Variety of materials used to manufacture photovoltaic cells rises the question about methods of accurate reference irradiance measurements, which could be applied on a level of photovoltaic plant deployment. Mismatch between spectral sensitivity of the photovoltaic module and reference sensor used for irradiance measurements increases uncertainty of available energy rating. Significance of spectral mismatch for overall energy production rating depends also on spectral variations of the solar radiation and circumstances of their appearance. Western Europe stays under the influence of maritime climate which is characterized by reliable cloud cover and high humidity. Carried campaign provides analysis of the spectral radiation in maritime climate and discusses its impact in term of PV systems applications.
