Online PV photovoltaic softwares
Photovoltaic Geographical Information System (PVGIS) provides a
map-based inventory of solar energy.
With Easy-PV you can easily create a PV project online for free.
You can create an instant schematic and use the performance calculator
to estimate PV system output.
Easy-PV was designed and built by the folks at Midsummer Solar
PV CO UK
PVWatts is a useful map-based free online software for US and
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.

Calculation solar for off-grid PV systems
Calculationsolar.com is a simple map-based free online calculator for
off-grid photovoltaic systems (design and simulation) anywhere in the
simulation program of roof-integrated or mounted
grid-connected photovoltaic systems.
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.
