Derivation of a tube Solar collector transmittance for beam and diffuse radiation
International Journal of Thermal Sciences, 2003Co-Authors: Mustapha Merzouk, Poubady Ramany Bala, Michel Feidt, Boumédiène BenyoucefAbstract:An expression of the total directional ray transmittance for a tube Solar collector cover glass has been derived. Numerical hemispheric integration has been made for both beam and diffuse radiation. From the equivalent Solar Altitude Angle we derived an expression that gives the equivalent Altitude which can be used to estimate the average transmittance of a tubular cover glass using the mean beam transmittance expression.

a Solar Altitude Angle model for efficient Solar energy predictions
Sensors, 2020Co-Authors: Sergio Herreriaalonso, Andres Suarezgonzalez, Miguel Rodriguezperez, Raul F Rodriguezrubio, Candido LopezgarciaAbstract:Sunlight is one of the most frequently used ambient energy sources for energy harvesting in wireless sensor networks. Although virtually unlimited, Solar radiation experiences significant variations depending on the weather, the season, and the time of day, so Solar-powered nodes commonly employ Solar prediction models to effectively adapt their energy demands to harvesting dynamics. We present in this paper a novel energy prediction model that makes use of the Altitude Angle of the sun at different times of day to predict future Solar energy availability. Unlike most of the state-of-the-art predictors that use past energy observations to make predictions, our model does not require one to maintain local energy harvesting patterns of past days. Performance evaluation shows that our scheme is able to provide accurate predictions for arbitrary forecasting horizons by performing just a few low complexity operations. Moreover, our proposal is extremely simple to set up since it does not require any particular tuning for each different scenario or location.
