Exercise purpose:

To become familiar with PV system specification procedure.

 

 

1.  Specify a PV system.

To specify renewable energy systems, choose the “Renewable” tab in the top-left window.

Click the right-mouse button placing the mouse point over the “Renewable’ window frame.

Select ‘PV’ and ‘Load PV Profile’ option; a list of PV systems available in the database will appear in the ‘Select from Database’ window.

Select ‘100W Poly’ from the list and click the ‘OK’ button.

Details of the PV system selected will be presented in the top-right window.

Enlarge the ‘100W Poly’ window by dragging the corner of the window.

Specify a PV system assuming the PV system will be installed with 500 panels facing south and tilting 45 degrees from the horizontal.

Type ‘500’ in the field of ‘Number of Panels’ and press ‘Enter key’. 

(Note: the ‘Enter key’ must be typed to make the input worked.)

Type ‘45’ in the field of ‘Tilt (degree from horizontal)’ and press ‘Enter key’. 

Type ‘0’ in the field of ‘Orientation (degree from south)’ and press ‘Enter key’. 

Finally, press the ‘select system’ button; a profile graph of the simulated energy supply by PV system  will be shown in the bottom window and an item with the title of ‘100W Poly vert south’ will be added to the tree of ‘PV’ in the top-left window as illustrated in the screen shot below.

Note: the items in the trees can be deleted by selecting ‘delete’ option after clicking the right-mouse button in the top-left window area.

You can rename the PV system you specified.

Place the mouse cursor over the specified item under the ‘PV’ tree and click it, which makes the text editable.
