N2 - Direct Normal Irradiance (DNI) is a critical component of solar irradiation for estimating Plane of Array (POA) irradiance on flat plate systems as well as for concentrating systems. Current approaches to measuring or estimating DNI suffer from drawbacks of either high equipment costs or low precision. A new approach is proposed, using Artificial Neural Networks to estimate DNI from the irradiance measures of five pyranometers. We consider various neural network topologies and training data sources and analyze the resulting errors. The estimated systems costs are found to be an order of magnitude less than a traditional pyrheliometer setup, with precision and accuracy significantly improved relative to a single pyranometer system.
