Sotiris,<br>
When you choose a PV from the list, all of the fields should still
show "?????" until you click on the "calculate" button in the
"calculations" section of the plugin. When you manually enter
parameters, the same is true; the fields at the bottom for the 5
reference parameters should all show "?????" until you choose
"calculate". The plugin transfers the computed results back to the
proforma if it was able to obtain a good solution once you select
"Exit" from the File menu. If the plugin did not solve to within
tolerances, it will show you its best guess of the answers but it
will not transfer the values back to the plugin automatically. You
can transfer them manually if you need to.<br>
<br>
If you are having trouble with a particular PV module, please send
me the input data. I may be able to generate the parameters for you
using a different tool.<br>
Best,<br>
David<br>

The file contains the inverter efficiency as a function of
the input power (in watts) and the input voltage (in volts).
These values are typically published by manufacturers on the
inverter specification sheets. If you do not have such a sheet
then you can use the example data file and scale the input
voltage and power to the range of input voltage and power that
you need. Inverters tend to be quite efficient (around 95%)
except when the input power is below about 5 to 10% of the
rated input power at which point their efficiency drops quite
a lot.<br>
Kind regards,<br>
