Abstract

The accuracy of models to estimate irradiance on inclined planes is tested by comparing the predictions to measurements taken with four instruments of various tilt and azimuth angles in Sede Boqer, Israel. The three models investigated are: the Perez model, Hay's anisotropic model, and the isotropic model. The Perez model is found to perform significantly better than the other two, with residual errors that are comparable to the accuracy of the measuring instruments themselves. The same data are also used to evaluated the precision of empirical correlations to estimate the direct component from global horizontal radiation, and to assess the sensitivity of the predicted irradiance on tilted surfaces to the errors associated with these correlations.

Measurements and models for total solar irradiance on inclined surface in Athens, Greece

Journal Article Kambezidis, H; Psiloglou, B; Gueymard, C - Solar Energy (Journal of Solar Energy Science and Engineering); (United States)

This article presents a comparative assessment of tilted irradiation models, using hourly measurements of total solar irradiation on a surface tilted 50 degrees and oriented south in Athens. Detailed measurements on inclined surfaces are carried out at the National Observatory of Athens and are unique in Greece. Twelve sky diffuse submodels are used with four albedo submodels to estimate the global irradiation on the tilted surface from data on the horizontal plane. Root mean square errors (rmse) and mean bias errors (mbe) are used to determine the intrinsic performance of each diffuse tilt/albedo submodel combination.

Dust-induced degradation of pyranometer sensitivity

Journal Article Feuermann, D; Zemel, A - Solar Energy (Journal of Solar Energy Science and Engineering); (United States)

The effect of dust accumulation on the sensitivity of pyranometers is studied in order to estimate the possible loss of accuracy associated with leaving the instruments unattended for extended periods of time. Under the and conditions of Sede Boqer, Israel, the dust effect reduces the sensitivity of a horizontal pyranometer by one permille per day. For periods extending up to several weeks, the degradation rate appears to be constant, and no saturation effects are observed. The propagation of the measurement errors associated with dust accumulation on pyranometers to the errors on the beam and global radiation values derived from amore »« less

Solar radiation on inclined surfaces

Journal Article Gopinathan, K - Solar Energy (Journal of Solar Energy Science and Engineering); (USA)

Measured solar radiation data for one location in Lesotho is used to test the applicability of two theoretical models for computing total solar radiation on inclined surfaces. The models selected for discussion are the isotropic model suggested by Liu and Jordan and the anisotropic model by Hay. The models are compared and tested for their applicability to locations in Lesotho and Southern Africa in general, on the basis of statistical error tests. A comparative study of the models shows that both the models are equally accurate for stations in Lesotho. The isotropic model is then used to estimate total radiationmore »« less

Spectral solar irradiance on inclined surfaces: A fast Monte Carlo approach

Journal Article Li, Mengying; Liao, Zhouyi; Coimbra, Carlos - Journal of Renewable and Sustainable Energy

Estimating spectral plane-of-array (POA) solar irradiance on inclined surfaces is an important step in the design and performance evaluation of both photovoltaic and concentrated solar plants. This work introduces a fast, line-by-line spectral, Monte Carlo (MC) radiative transfer model approach to simulate anisotropic distributions of shortwave radiation through the atmosphere as photon bundles impinge on inclined surfaces. This fast Monte Carlo approach reproduces the angular distribution of solar irradiance without the undesirable effects of spatial discretization and thus computes detailed POA irradiance values on surfaces at any orientation and also when surfaces are subjected to the anisotropic ground and atmosphericmore »« less

Statistical comparison of models for estimating solar radiation on inclined surfaces

Journal Article Ma, C; Iqbal, M - Proc. Annu. Meet. - Am. Sect. Int. Sol. Energy Soc.; (United States)

The objectives of this study are to compare statistically three models for estimating solar radiation on inclined surfaces and to recommend one that is general and accurate. The isotropic model, and Klucher's and Hay's anisotropic models are chosen for discussion. The hourly and daily formulations of these models are briefly described. Results show that they all produce large errors at steep slopes. The errors are minimum during the summer months. The isotropic model underestimates consistently throughout the year resulting in the worst performance. Hay's model also under-estimates constantly but by a smaller amount. Klucher's model overestimates in the summer andmore »« less
