Solar radiation databases

This section provide a list of solar radiation and meteorological databases free or to purchase.

Worldclimate (USA) gives Worldwide rainfall and temperature database (85000 sites).

The Soweda application presents an alternative method to provide free hourly global solar tilted irradiation data for the whole European territory through a web platform.
The solar irradiation data generated are obtained by combining clear-sky simulations and weather conditions data.
This service offers solar radiation data from up to 5 days before current date, and until one hour before current time.

US dynamic solar atlas; on grid cells of ~ 40 km by 40 km provides monthly averages of daily total solar resource available to flat plate photovoltaic modules and concentrators. Only USA.
NREL

Satellite-based service for high-resolution solar radiation for Europe, Africa and Asia (DLR, Germany)

OpensolarDB is a database with average global daily solar radiation data for each month of the year as measured on the ground. The uniqueness of this solar database is that it is open for everybody, open for extracting data and open for introducing data. Everybody can extract data. This extracting can be done in various ways: by downloading, doing a copy/paste on-line, by connecting to a webservice or by Flex Remote Object services (amf format).
The solar radiation data in OpensolarDB are free and very accessible in many ways.

Restscreen is a free software that includes worlwide solar radiation database.
RETScreen

The NCEP/NCAR is a Reanalysis Project Atmospheric analyses using historical data and analyses of the current atmospheric state. Coverage: the entire world, with a grid cell of approx. 2 degrees in size. Available also through SoDa portal.
