. . . . . and why / why not?
garygid said:Not TOU because:
1. SDG&E billing (with PV over-generation in some time slots)
has not been explained.
2. Likely that one gets "credited" little for over-gen, and gets charged
more for even Super Off-Peak usage.
3. With Net metering, I can charge any time,
and from any socket that is convenient.
4. No need for an expensive install of a 2nd meter.
5. There does not APPEAR to be any significant advantage to using TOU.
The price of energy is much higher during on-peak hours, especially during the summer months, when a SES typically produces electricity at maximum output. This means that every excess kilowatt-hour your system generates is credited to your account at the higher rate during the on-peak period.
thankyouOB said:With TOU, you produce in the four summer months at 22 cents a kWh and consume at 11 cents.
In the darker months, the ratio is closer but still advantages the daytime versus nighttime.
This thread is about grid-tied PV, i.e. solar panels. I certainly hope that no one with solar panels is hitting tier 5.EricH said:Each tier costs more than the last, so that high-usage customers like me hit Tier 5, which is very costly. So your cost to charge on the regular domestic rate depends heavily on what "tier" your usage will hit with your Leaf plugged in.
garygid said:Since I am not in EVProject territory, I pay for any install work needed to get ready for a 2nd meter. So, I have only one meter, and it is not TOU.

I believe the above is a misunderstanding. EVProject is NOT paying for install work related to second meter. I asked, they refused. I wanted a more comprehensive upgrade to my panel than the minimum needed to be ready for the charger. I even offered to pay for it, and they told me to get someone else to do it.

In SDG&E territory (and others?), SDG&E is working with Ecotality to get second meters installed so they can do a pricing/usage study. Ecotality's contractor will be installing the second meter socket, and SDG&E will be installing the meter, both at no cost to me.thankyouOB said:garygid said:Since I am not in EVProject territory, I pay for any install work needed to get ready for a 2nd meter.

True. And the utility's numbers too. My PV meets just over 100% of my house needs. If after studying the results of the EV Project, SDG&E picks a rate structure that is advantageous to night time EV charging, then two meters will be best for me. If I recall correctly one of the rates goes as low as 6.7 cents. At those rates it wouldn't pay to install more PV to essentially "buy" back the power from myself at the marginal feed-in tariff rate expected to be something like 5.0 cents, barely lower than the SDG&E rate without any capital outlay.Jimmydreams said:It all depends on your numbers....

As with that, EVProject will install the EVSE and the "hole" for the second meter, SDG&E will provide the meter and install it--all for free (my install is straightforward enough).
YMMV, based on your conditions.
