PVGis

Online free solar photovoltaic energy calculator for stand alone or connected to the grid PV systems and plants, in Europe, Africa and Asia. Solar electricity generator simulation and solar radiations maps

PVgis is  the ideal free online tool to estimate the solar electricity production of a photovoltaic (PV) system.
It gives the annual output power of solar photovoltaic panels.
As a photovoltaic Geographical Information System it proposes a googlemap application that makes it easy to use.

The area covered by the calculator is Europe Asia and Africa.

This application calculates the monthly and yearly potential electricity generation E [kWh] of a Photovoltaic system with defined modules tilt and orientation.

Note that PVgis is only available online, in english, italian, french, spanish and german. 
Pvgis is a free solar PV energy calculator implemented by the JRC (Joint Reseach Center) from the European Commission's in-house science services.

PVGIS can't be downloaded. To download free softwares see Free Solar photovoltaic software or Softwares and tools from inverter manufacturers.

NEW : Now PVgis covers also asia (China, India, Indonesia, Russia...)

PVGIS for PV remote systems in Asia, Africa and Europe

For the Africa/ASIA map and now Europe map it is possible to calculate the solar energy generation for a stand-alone PV system (right-top menu). This is useful to get a good assesment of the energy power required to match your electrical needs in remote area not connected to the grid. 

After chosing your place on the map you have to enter :

Optional hourly consumption file  : the uploaded file should consist of 24 hourly values, each on its own line, with the sum of the numbers equal to 1.
Inclination of modules : slope of your solar panels
Orientation of modules : Orientation (azimut or direction) of your solar panels

Then you will get graphs and tables that show the (estimated) daily amount of electric power you can expect in each month from a Solar Home PV system with the properties you entered (using optimal inclination, if you requested so). It also shows the yearly average production per day and gives statistics data such as the number of days corresponding to a state of charge or discharge of battery.
