Correlation model of hourly diffuse solar radiation based on ASHRAE model: a study case in India
Measurements of diffuse and global solar radiation carried out from January 2001 to December 2005 at Ahmedabad, Mumbai, Calcutta, Chennai and Pune cities of India, representing varying weather conditions of the entire country, have been used to develop the correlation model for the estimating hourly values of diffuse solar radiation on horizontal surface. The comparisons of the present estimated ...

Artificial intelligence techniques for prediction of solar radiation data: a review
Artificial intelligence (AI) techniques are becoming useful as alternate approaches to conventional techniques. They have been used to solve complicated practical problems in various areas and are able to deal with non–linear problems. AI techniques have been applied for modelling, identification, optimisation, prediction, forecasting, and control of complex systems. Artificial neural networks ...

Night operation of solar chimney power system using solar ponds for heat storage
An alternative method of heat extraction from salt gradient solar ponds to solar collector is investigated with the aim of night operation for solar chimney power system. Some details of the combined power system integrated with solar ponds and solar chimney power system are also provided. Using a developed mathematical model, theoretical analyses are carried out to investigate the performance of ...

Artificial neural network based models for forecasting electricity generation of grid connected solar PV power plant
This paper presents an artificial neural network (ANN) approach for forecasting the performance of electric energy generated output from a working 25-kWp grid connected solar PV system and a 100-kWp grid connected PV system installed at Minicoy Island of Union Territory of Lakshadweep Islands. The ANN interpolates among the solar PV generation output and relevant parameters such as solar ...

Lowering uncertainty is fundamental to managing solar investment risk
The principal input to the rate of return calculation for a solar farm asset is the expected revenue generation from the solar farm. This highlights the importance of high quality solar irradiance data: revenue generation is primarily influenced by the availability of solar irradiance at that location over time. Humans dislike uncertainty Humans aren’t big fans of uncertainty. We go to ...

Estimation of monthly average solar radiation in Libya
In order to estimate the monthly average global radiation, regression equations for eleven stations in Libya are fitted, using monthly average hours of sunshine duration as predictors. Since only eight years of monthly average global radiation are available for each station, a reliable model for estimating solar radiation for each single month could not be obtained. The monthly data were merged ...
