It is the presizing step of a project. It's aim is to quickly define the general features of a planned PV system.

In this mode the system yield evaluations are performed very quickly in monthly values, using only a very few general system characteristics, without specifying specific system components. A rough cost estimate of the system is also available.

The procedure is straightforward: you just go over the three buttons "Location", "System" and "Results".

First click on "Location" button: you have to give a description of your presizing project in order to identify it after saving. The presizing projects are simple files which don't allow for several variants.

Choose a location in the database. You can obtain the location details, or even create or import a new location from Meteonorm or US TMY data, using the "open" button.

When necessary you can also define an Horizon profile.

Click on "System" button. The presizing procedure is then specific for each type of system:

Grid-connected system,

Stand-alone system,

Pumping system.
