The last 2 weeks I'm only peaking at 7.4kw.
I didn't realize how fast they get dirty. I cleaned them off twice.

Got my first power bill. It's down at least $150.
But the payment is a little over $200. So it's not going to save any money till after its payed off and that's fine with me.
After 18 months, the loan "remonetizes" which gIves people plenty of time to spend the federal tax credit return money on other sht.
That's your chance to give the solar panel finance company the federal money and keep the loan at around $200 per month (for me), or blow the federal tax credit and the loan payments goes up to around $350 per month.
So I'll probably put the state credit, fed, plus an additional $8k to $10k and see if I can get a lower interest rate and a shorter loan.

Ahhh 2 summer months in a row my Power bill was knocked down to just the surcharge.
But power is so cheap here it will never pay for it's self. The solar panel bill is about $50 more than my power bill.
But in the winter it's really going to hurt. The solar panels won't produce squat and I'll have my full January and February power bill.

September looks like it will be a good month. Hardly any A/C use, solar panel production is down around 4% compared to july for clear days, but there's been so many cloudy days I'm down 30% compared to the same time in august.
September could be a surcharge only month if the sun comes out.

Dala thanks for sharing. As an electrician it's interesting to see different codes,equipment, wiring method. So at what voltage and amperage do u charge your leaf at?

Looks like thermal only breakers used in industrial equipment.

Dala thanks for sharing. As an electrician it's interesting to see different codes,equipment, wiring method. So at what voltage and amperage do u charge your leaf at?

Thanks! Yeah I charge at 3.3kW, 230V*16A. I upgraded so that I got a 3-phase outlet, so that I can charge with 11kW (3*230V*16A) once I get the upgraded on-board-charger retrofit installed.

Is 230 your line to neutral or line to line voltage?

Is 230 your line to neutral or line to line voltage?

It is the line to neutral, so quite powerful stuff. The European AC system is a 230V system. Cabling for 1-phase systems is L+N+PE (Line+Neutral+Protective Earth). In 3 -phase systems there is L1+L2+L3+N+PE. Even the most basic electrical install is 3-phase minimum, so you can power quite the amount of heavy machinery.
