CHEETAH WEBINAR - Solar Resource Knowledge for PV applications: current tools and needs
Webinar - April, 4th 2017 - 11:00 – 12:10 CET
Dr. Jesús Polo
Solar resource knowledge is an important task at several stages of any solar system PV facility and project. The accurate knowledge of incoming solar irradiance is of highly interest in the preliminary studies, in feasibility analysis, and during performance evaluation and monitoring of PV systems. This webinar will present an overview of the fundamental basis of solar radiation at the earth’s surface (solar radiation components, interaction with atmospheric constituents), measuring devices, data bases of solar radiation and sources of information, and modelling solar radiation for PV application.Measuring the solar radiation components properly is essential at many different stages of solar energy projects (site prospecting, modelling and monitoring plant output, forecasting, etc). Uncertainty in solar resource assessment is probably the most contributor to the uncertainty in energy rating of any solar system for electricity generation (both in PV and CSP technologies). Likewise, modelling solar irradiance components is essential in many aspects and it usually requires accurate ground measurements to reduce the uncertainty of the output. In particular, accurate of long-term solar radiation time series is fundamental to bankability and feasibility studies. The webinar is intended to give a general overview on the role that solar resource assessment plays in PV deployment and on the main characteristics of available sources of information of solar radiation as well.
