The National Solar Radiation Data Base (NSRDB), consisting of solar radiation and meteorological data over the United States regions surrounding countries, is a publicly open dataset that has been created disseminated during last 23 years. This paper briefly reviews complete package surface observations, models, satellite used for latest version NSRDB as well improvements in measurement modeling technologies deployed current provides irradiance at 4-km horizontal resolution each 30-min...
Concentrating solar power projects require accurate direct normal irradiance (DNI) data including uncertainty specifications for plant layout and cost calculations. Ground measured are necessary to obtain the required level of accuracy often obtained with Rotating Shadowband Irradiometers (RSI) that use photodiode pyranometers correction functions account systematic effects. The Si-pyranometers has been investigated, but so far basically empirical studies were published or decisive...
We calculated the energy yields of perovskite/CIGS tandems for real world irradiance and temperature variations.
The National Renewable Energy Laboratory (NREL), University of Wisconsin, and Oceanic Atmospheric Administration are collaborating to investigate the integration Satellite Algorithm for Shortwave Radiation Budget (SASRAB) products into future versions NREL's 4-km by gridded Solar Database (NSRDB). This paper describes a method select an improved clear-sky model that could replace current SASRAB global horizontal irradiance direct normal irradiances reported during conditions.
Terrestrial ultraviolet radiation (UV) is a primary factor contributing to the degradation of photovoltaic (PV) modules' efficiency and reliability over time. Therefore, accurate knowledge terrestrial UV incident on surface PV materials essential understand modules provide reliable assessment their service life. As deployed in various climate zones, it crucial that information available at locations. However, availability data-measured or modeled-is extremely limited. On other hand, total...
The range of resource data sets spans from static cartography showing the mean annual wind speed or solar irradiance across a region to high temporal and spatial resolution products that provide detailed information at potential energy facility. These are used support continental‐scale, national, regional renewable development; facilitate prospecting by developers; enable grid integration studies. This review first provides an introduction sets, then overview common methods for their...
By investigating the long-term observations at Atmospheric Radiation Measurement (ARM) Southern Great Plains (SGP), we find that routinely used Beer-Bouguer-Lambert law and models empirically separate direct normal irradiance (DNI) from measurements of global horizontal (GHI) have dramatic unexpected bias in computing cloudy-sky DNI. This has led to tremendous uncertainty estimating electricity generation by solar energy conversion systems. To effectively reduce bias, this study proposes a...
The advent of bifacial PV systems drives new requirements for irradiance measurement at projects monitoring and assessment purposes. While there are several approaches, is still no uniform guidance what parameters to measure the optimal selection placement sensors arrays. Standards emerging address these topics but not yet available. In this paper we review approaches which being discussed in research literature pursued early systems, provide a preliminary guide framework developers planning...
This study examines the impact of various aerosol databases on accuracy irradiance predictions pertaining to National Solar Radiation Database (NSRDB) over Americas. Compared Modern-Era Retrospective analysis for Research and Applications, Version 2 (MERRA-2) reanalysis moderate resolution imaging spectroradiometer (MODIS) space-borne observations, improvements that have been made develop SOLSUN database are described, using a monthly temporal 4-km spatial resolution. Relative MERRA-2, these...
Abstract The ground ultraviolet (UV) solar radiation is relevant due to its impacts on plastics degradation (mainly UVA) and human health (UVB erithemic UV (UVE)). measurements are not as ubiquitous the relatively common global horizontal irradiance (GHI) measurements. Three simple models that estimate UVA, UVB, UVE components of from GHI ozone column information locally adjusted validated. Five one-minute datasets three sites in southeastern South America two United States used for...
