Artificial Intelligence Based Global Solar Radiation Prediction

2023
Solar energy is one of the cleanest renewable energy sources and has no environmental impact. Solar radiation data is important to solar engineers, designers and architects which is also fundamental for efficiently determining irrigation water needs and potential yield of crops, among others.

Assessment of Global Solar Radiation over Rwanda

2007 International Conference on Clean Electrical Power, 2007
This paper aims to estimating the global solar radiation in Rwanda. We mainly treated the particular case of Kigali where meteorological data records (sunshine duration, temperature, pressure and humidity) over a period of 20 years (1974 to 1993) are available.

Simple hourly global solar radiation prediction models

Renewable Energy, 1991
Abstract Three simple prediction models of hourly global radiation, namely, a normal distribution model (ND), a half-sine wave model (HW), and a polynomial model (PO), are tested using data for a period of five years of the area of Amman, Jordan. The results show that none of these models alone can adequately represent the tested data.

Global solar radiation measurements in Maceió, Brazil

Renewable Energy, 2005
Abstract This work focuses on the variability of the global solar radiation over the area of Maceio (9°40′S, 35°42′W, 127 m), located in Northeastern State of Alagoas, Brazil, during the1997–1999 period. Solar radiation variability was evaluated on 5 min, hourly, daily, monthly and seasonal scales.

Global solar radiation in Northeastern Saudi Arabia

Renewable Energy, 1999
Abstract This paper presents the actual global solar radiation on a horizontal surface along with the prevailing meteorological conditions encountered during the measurement period from 1 January–31 December, for one complete year, in the Arabian Gulf Coast near the city of Dhahran.

Simplified Method To Estimate Global Solar Radiation

Proceedings of the 25th Intersociety Energy Conversion Engineering Conference, 1990
In order to simplify solar radiation analysis and to asses its effect on energy estimation, a simplified method to estimate average global horizontal solar radiation is required. This paper analyzes global solar radiation for (8) eight Iraqi cities and (8) eight U.S.A cities and proposes a method for generalizing this data for use in different location.

Simple model for estimating global solar radiation

Solar & Wind Technology, 1985
Abstract A variety of numerical models for calculation incoming solar radiation on horizontal surface are existing. The preferences of any model are due to level of accuracy and simplicity. In this paper, a one layer model is proposed (in case when layer information are not available).

Predicting global solar radiation for North Algeria

RE&PQJ
Having a complete and effective radiometric database is very crucial in the renewable energy field for the design of solar photovoltaic and thermal system. Despite the existence of the chain of radiometric measurement at the University of Blida, data acquisition of various components of radiation is still having problems, such as gaps in basic ...

Monthly mean hourly global solar radiation estimation

Solar Energy, 2012
Abstract In this paper, selected empirical models were used to estimate the monthly mean hourly global solar radiation from the daily global radiation at three sites in the east coast of Malaysia. The purpose is to determine the most accurate model to be used for estimating the monthly mean hourly global solar radiation in these sites.

STOCHASTIC MODELING OF DAILY GLOBAL SOLAR RADIATION

International Journal of Solar Energy, 1989
A general model for the simulation of the daily global solar radiation is introduced. The model development is based on the removal of the annual periodicity and seasonal variation of the solar radiation, through an appropriate transformation, so that the transformed data form a stationary time series (with constant mean and standard deviation).
