Smart Photovoltaic System
TL;DR: In this paper, the effectiveness of the PV cells are affected by dust, humidity, temperature, and settlement of PV panel's surface, and the rate of efficiency drop varies from one variable to another depending on its reaction with other variables.

The Effects of Atmospheric Modeling Covariance on Ground-Based Hyperspectral Measurements of Surface Reflectance
TL;DR: In this paper, the authors present a framework for estimating the covariance and uncertainties of atmospheric parameters and the reflectance spectra of urban surfaces in high-resolution ground-based hyperspectral images.

Data Mining Models for Short Term Solar Radiation Prediction and Forecast-Based Assessment of Photovoltaic Facilities
Jiménez Pérez,Pedro Francisco +1 more
TL;DR: A data mining models to forecast solar global radiation 24 hours ahead and to use these predictions to evaluate the performance of photovoltaic systems and a methodology to assess solar power plants performance based on forecasted solar radiation.
Albedo estimates for land surface models and support for a new paradigm based on foliage nitrogen concentration
TL;DR: In this article, the authors calculated growing season albedos for deciduous and evergreen forests, crops, and grasslands based on over 40 site-years of data from the AmeriFlux network and compared them with estimates presently used in the land surface formulations of a variety of climate models.

Chlorophylls - natural solar cells
TL;DR: In this article, a molecular modeling study was conducted on a series of six natural occurring chlorophylls and the orbital energies were used to estimate frequency of transitions between occupied molecular orbital and unoccupied molecular orbital energy levels.

Simple Solar Spectral Model for Direct and Diffuse Irradiance on Horizontal and Tilted Planes at the Earth's Surface for Cloudless Atmospheres
Richard E. Bird,C. Riordan +1 more
TL;DR: In this paper, a simple model for calculating direct normal and diffuse horizontal spectral solar irradiance for cloudless sky conditions was described. But the model was developed using rigorous radiative transfer codes and limited outdoor measurements.

The solar radiation between 3300 and 12500 Å
Heinz Neckel,Dietrich Labs +1 more
TL;DR: In this paper, the authors presented a merging of the absolute integrals of the disk-center intensity for 20 A wide spectral bands and the ratios of mean to central intensity derived from recent observations of the center-to-limb variation of those bands (λ 6600 A).
Journal ArticleDOI
Parameterized transmittance model for direct beam and circumsolar spectral irradiance
TL;DR: In this article, an upgraded spectral radiation model called SMARTS2 (Simple Model of the Atmospheric Radiative Transfer of Sunshine) is introduced, based on spectral transmittance functions for the main extinction processes in the cloudless atmosphere: Rayleigh scattering, aerosol extinction, and absorption by ozone, uniformly mixed gases, water vapor, and nitrogen dioxide.
