Algorithm for modelization and control of solar total radiation, using the derivative

Abstract:

Detailed knowledge of the solar resource is important for its possible applications in solar use, design of buildings and biological effects, among others. In this paper, we present an algorithm for the calculation of global solar irradiance based on a parametric model, which allows us to obtain global solar irradiance, at any geographical location and time of day. Also, we present a new algorithm using the derivative. Results were compared with measurements taken with a solar radiometer, supporting our arguments. We found percentage of discrepancy of 1.6% to 6.8% in days of May, 2007). Another very useful application of the algorithm is to determine the threshold levels of solar irradiance for Rosario and Concepción del Uruguay, Argentina. The algorithm produces an alert signal that is transmitted when an error happens. We present applications of the algorithm, which allow modifying the incorrect measurements in near real time, giving more confidence to the published data.
