The Glen Waverley Uniting Church PSALTER
Day Night Electricity
- Gauging the benefit and ideal size of a battery is complex.
- One measure is the number of days when the day time export exceeds the night time consumption, so that the tomorrow morning charge in the battery exceeds this morning.
- To gauge this, I downloaded the data for the church from United Energy. In this file B1 is export and E1 is import. We do not have any other monitoring of our panels.
- The kWh in each 5min interval were summed for 6am to 6pm (Day) and 6pm to 6am (Night). As expected the nigh time export was zero except for small numbers during early morning in mid summer. Night time import therefore equals night time consumption
