Here is my
daily consumption (including hot water and heating) vs my
weekly production in kWh for the last 8 weeks :
- OPH = Off Peak Hours (10:30PM - 06:30AM) : 12.98 kWh/night
- PH = Peak Hours (06:30AM - 10:30PM) : 27.63 kWh/day
- day = OPH + PH : 40.61 kWh/day
- PV/week : 12.79 kWh/week = 1.83 kWh/day
ie I'm currently consuming by night what I'm producing in one week... Happily in summer I'll produce daily around 75% of my daily consumption
Remarks :
- This production is done with 23 mē (~207 sq-ft), which correspond to 3kWc. How much sq-ft can you put on the roof of a car ?
- My PV system is static (roof integrated) so its orientation isn't optimized as it would be on the roof of a car,
- There is a correlation between consumption and production. During 1st week, the heating system was misconfigured... Week 7 was the coldest. Weeks 5 (Xmas week, far from home) & 8 were warmer and sunnier that previous ones.
