Description:
PV-log is a simple program to use for manually logging readings from a Time-of-Use electric meter.
It was written with the Photovoltaic (Solar) Array owner in mind.
There are provisions for logging the instantaneous power from the inverter, too.
Finally, there is a comment field for logging the weather, or any other interesting information.
The output is a DOC format file containing tab-separated values.
This file can be transferred to a desktop computer, and imported into a spreadsheet program.
