Solar parameters for preliminary solar resource assessment at representative points
The Atmospheric Science Data Center of NASA is free online web database providing general information about wind potential all over the world. Thorough the web site can be received information for wind speed and direction at 10 and 50m height at representative points.
The free-of-charge RETScreen Clean Energy Project Analysis Software under the web site can be used to evaluate the energy production and savings, costs, financial viability and risk for solar thermal energy projects. It includes also the summarized solar intensity data.
Joint Research Center of European Commission is Photovoltaic Geographical Information System database providing interactive access to solar resource and photovoltaic potential at representative point all over the world. The database contains information for solar potential for over 25 year's period.
