Sažetak
In this paper we develop and verify 3 neural- network-based models for predicting the global solar irradiance on tilted surfaces. Models' inputs are: (i) solar irradiance components -- direct (normal), diffuse (horizontal), ground reflected and/or global (horizontal) solar irradiance, (ii) sun position on the sky dome, i.e., solar zenith and azimuth angles, and (iii) tilted surface orientation angles, i.e., tilted surface tilt and azimuth angles, while models' output is the global solar irradiance incident with the tilted surface. These models are then compared with 3 isotropic and 6 anisotropic irradiance models for tilted surfaces from literature. Solar irradiance data used for model identification and verification is recorded in the 10 sec time step and then integrated on the 10 min time step through a month period in 2013, and is filtered out in order to retain only high-quality solar irradiance measurements.
