The most flexible way for defining a custom feed-in tariff is to input it as an ASCII (CSV) hourly file.
Hourly Parameters file
The ASCII input source file should be prepared in a spreadsheet program (like MS-EXCEL), in the CSV-format (Comma Separated Values, separator may be semicolons or commas).
You can find a template named "Hourly Parameter_Template.CSV" in the program's location, usually C:\ program files (x86) \ PVsyst7.x \ DataRO \ PVsyst7.0_Data \ UserData \.
However since version 6.76, you have the opportunity of copying all the template files in your own workspace, C: \ users \ YourSession \ PVsyst7.0_Data \ Templates \, using "Files > Workspace > reload templates" in the main menu.
When modified, you will put your data file in your workspace \"user"\ PVsyst7.0_Data \ UserHourlyParams \
PVsyst standard format for hourly parameters
The required format for the import of hourly parameters in PVsyst is the following:
| - | Text file (CSV format with commas or semicolons) written in ANSI (not UTF8). |
| - | All lines beginning by # are comments, ignored. |
| - | The blank lines are ignored. |
| - | The first line without # holds the column titles. It should begin by "Date", and "Price per kWh" for an hourly tariff. |
| - | Second line: units of the data in this column, will be read and interpreted by the program. In this line, cell under "Price per kWh" should contain the currency code used to define the price. |
This 3-letter currency code (EUR, USD, GBP, CHF...) must be one of the currencies used in Pvsyst. You can access the list of available currencies from Economic evaluation tool and define your own currencies and exchange rates.
| - | First column of data: date and hour in EXCEL format (both Europen DD/MM/YY hh:mm or US MM/DD/YY hh:mm formats are recognized). |
| - | Other columns: values according to the column title and units. Each value under "Price per kWh" column is the feed-in price per kWh for the hour specified in the first column. |
| - | The file should contain all hours of a generic year (from 01/01 at 0H00 to 31/12 at 23:00). The year is ignored. |
| - | These dates/hours are not related to the real dates of your input meteo file: they are for each hour of a generic year. |
Use of the file
After carefully preparing this file, the dialog accessible from "Import" will ask for choosing it in your workspace \ UserHourlyParams \.
If the file is correctly formatted, the content will be imported and stored in the economic evaluation. The values are automatically used for the income calculation.
