High-quality long-term irradiance measurements are the criteria for judging whether a solar radiation dataset can benefit. However, apart from a handful of observatories in the

The range of observation points in the NSRDB database is limited, and many potential solar power plants do not have good meteorological observation stations near
Typical Meteorological Year (TMY) data files were first created from long-term data files in the NSRDB database for analysis of building performance. At the time,
Canadian meteorological resources and engineering data set (cweeds) is a data set of 143 observation locations in Canada generated by computer. This includes hourly meteorological
With the deepening of people’s understanding of solar energy resources and the increasing demand for solar energy resource information, the National Renewable Energy Laboratory (NREL)
Between 1951 and 1975, the National Weather Service had about 60 observatories measuring total horizontal irradiance (GHI). This group of observatories, although they have their
Robust solar radiation datasets are key to competitive solar project financing. Financiers generally consider solar resources to be stable from year to year compared to
Variations in energy forecasts include: interannual variability, data uncertainty, modeling assumptions and methods. Several of these variables are discussed below. 1. year changeInterannual variation (lAV)
Exceeding Probability Statistics is a statistical measure that describes the probability that a particular value is equal to or exceeds. For example, a 90% exceedance
The variability of solar energy resources affects the technical performance of solar power systems on all time scales. In addition, this variability affects the financial
