Retrieving SolarEdge solar panel generation data from the API using Python

# Edit this date range as you see fit
# If querying at the maximum resolution of 15 minute intervals, the API is limited to queries of a month at a time
# This script queries one day at a time, with a one-second pause per day that is polite but probably not necessary
