We had the digital power meter installed 10 days before the installation of the solar panels. The meter reading, upon the switch on of the solar inverter, was at 283, meaning the average usage was 28kwH a day (must point out, we had been enjoying warmer than usual temperatures for these 10 days, so Synergy electricity usage was below average. Normal Average is 34kwh per day). Switch on was at 11:30-ish am, so the first day wasn’t a full day of solar energy.
Meter Reading on switch on: 283
Day 1: 295 (mostly sunny skies)
Day 2: 305 (clear sunny skies)
Day 3: 317 (partly cloudy)
Day 4: 332 (partly cloudy)
Day 5: 347 (partly cloudy)
Day 6: 370 (heavy clouds, rain, and cold. Heating used)
Day 7: 380 (clear Sunny skies)
1/3 the average use of Synergy provided electricity. Even on cold rainy day, we used 1kwh less than the ‘winter average’.
So, next year, we will be getting another 6 panels for the other north facing roof.
