Estimation of global solar irradiation on horizontal and inclined surfaces based on the horizontal measurements

Publication year: 2011brbSource:/b Energy, In Press, Corrected Proof, Available online 22 January 2011brA.M., Muzathik , M.Z., Ibrahim , K.B., Samo , W.B., Wan NikbrSolar radiation data are essential in the design of solar energy conversion devices. In this regard, empirical models were selected to estimate the global solar radiation on horizontal and inclined surfaces. The hourly solar radiation data measured at the study area during the period of 2004–2007, were used to calculate solar radiations using selected models. The selected models were compared on the basis of statistical methods. Based on the results, a new model, H/Ho = 0.19490 + 0.4771(n/N) + 0.02994 exp(n/N) has been developed, based on Kadir Bakirci linear exponential model. This is highly recommended to estimate monthly mean daily global solar irradiation, on a horizontal…br Research highlights: ► The monthly average daily global solar irradiation on horizontal surface can be estimated using linear exponential regression equation H/Ho = 0.1949 + 0.4771(n/N)+0.02994 exp(n/N). ► The monthly average daily global solar irradiation on inclined surface can be estimated using Olmo et al. model for the state of Terengganu, Malaysia. ► These two models are relatively simple models to estimate monthly average daily global solar irradiation.

    is it possible to use short term data, say like half an hour,15 minutes etc to estimate monthly averages. otherwise its a good well research paper.thanks
