PVWATTS

PVWatts is a useful map-based free online software for US and international photovoltaic sites analysis.
It could give the global annual energy output of PV systems connected to the grid in USA or in many part of the world. For many locations it could also provides PV energy output hourly values.
PV WATTS also provides international solar maps.
This powerfull  and easy to use tool is developped by the NREL  (US National Renewable Energy Laboratory)

Caution : it works only for crystalline solar panels.

DIAFEM

Only for spain. DIAFEM is an online free application for designers, installers and anybody interested in renewable energy, for the design and calculation of electrification facilities no connected to the grid. Allows small wind turbines design facilities, photovoltaic and mixed to meet the energy needs of a demand. The tool asks, a number of technical data, to identify the project and a specific energy demand, in order to perform the calculation and design of the facility. Results are displayed in a technical report.
