The solar screen displayed "file not found" when the solar log was not available to the script. this means that the sunsaver_log.py script hadn't been run, which needs to happen as a cronjob as per the readme. it does not mean that solar is not connected to the pi, just that there is no solar log file available. the solar might be plugged in, just not writing to that log file yet. the solution to this screen is to run sunsaver_log.py, and then if the solar is truly not connected then there will be a different error that shows after that- indicated by all the fields in the log file being marked as "NA"
