Preliminary design

This is the presizing step of a project. Its purpose 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: simply work through the three buttons Location, System, and Results".

First, click the Location button: provide a description of your presizing project to identify it when saving. Presizing projects are simple files that do not support multiple 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 a Horizon profile.

Click the System button. The presizing procedure is specific to each system type:

Grid-connected system,

Stand-alone system,

Pumping system.
