If I'm reading these posts correctly I see that PG&E handles the billing differently than SDG&E. Down here in SDG&E territory I am billed for NBCs in addition to the minimum daily charge. The NBCs are now a separate line item charge and are not part of the MDCs anymore.

After we got the PTO email from SDG&E my installer contact came right out and showed me how to switch it on. It’s been running smoothly ever since.

Yes, under the right circumstances it can happen quickly. It did for me back in early 2019 in SDG&E territory. Installation finished on a Monday. City inspection on Tuesday, Paperwork submitted to SDG&E on either Tuesday or Wednesday of that week with PTO granted on that Thursday.

Sounds about right to me for a south facing orientation with little to no shade in Las Vegas

My modest 4kW system produced 26.9 kWh today (3/26). It was a good day for solar in Poway, CA

I can answer a few of your questions. I can't address the CCA vs SDG&E question since I'm in Poway and only have the choice of SDG&E If you will truly be a net producer there are better rate plans than EV-TOU-5 which has a fixed $16.00 per month charge. On all rate plans under NEM 2.0 you...

As a net producer for the year I try to minimize NBCs when charging my RAV4 Prime. If the sun is shinning brightly I charge it early afternoon so solar production supplies most of the charge. If it's a rainy/cloudy day, I charge at night during my Super Off-Peak period (after midnight). My...

Perhaps a real life example will help you understand TOU periods. Note that I am in SDG&E territory and on their TOU-DR1 rate plan so your numbers will be different but the TOU concepts will be the same. Here's my latest month's numbers For my On-Peak period I used 101kWh and solar generated...

One way to use up that credit is to use grid power, especially at peak rates rather than using your Powerwall(s). Set that reserve to a high level unless you are worried about long power outages

Only 12 panels for 8 PWs seems like a mis-match. Will you have enough solar to keep those PWs charged up? I wouldn't where I live in sunny SoCal. My NEM agreement precludes charging the PWs from the grid.

Not quite enough detail about your electricity usage, especially about how much you use in each TOU period, to give you an accurate answer. I am not on SDG&E's EV-TOU5 rate but I understand you should be paying the $16 per month service fee plus any NBCs you accumulate. SDG&E is currently...

I can't add much to this extensive post but, as I look at my latest SDG&E bill, I am producing excess solar mainly during off-peak times and drawing power from the grid during peak times. With no battery installed, that means I am currently "selling" my excess electricity to SDG&E at ~$0.36 per...

SDG&E uses the net energy from the meter on a 15 minute interval to calculate NBCs. For each 15 minute period , if you import more energy from the grid than you export, you will accumulate NBCs on the net energy for that 15 minute period. Currently SDG&E is charging $0.01971 per kWh for NBCs...

You are asking a lot of a 7.2kW solar system if you expect to both keep the Powerwall charged up and have excess power to charge your Tesla during the day. How much excess kWhs do you expect to have once you've covered your household needs?

Wayne has thrown some serious math at us and come up with a good approximation to use in PVWatts. An easier, but not necessarily more accurate, method would be to perform two PVWatts runs, one for each cluster of panels, and add the results together.

I live firmly in the pay attention to what they do not what they say they do world. I doubled checked my NBC math and confirmed that SDG&E tabulates NBC data on 15 min intervals. If I add up the NBCs based on hourly data I end up short of what SDG&E bills me for. If I add up the 15min data I...

What size inverter or details on microinverters if used? Array orientation? Tilt on panels? These have an influence on your solar production and can limit the power developed from your solar panels. In addition, heat will lower the efficiency of your panels. Panels work best on full sunny but...

In sunny San Diego County we haven't needed a PowerWall yet. With the exception of a 3 hour power outage last year we have had very steady electricity provided by SDG&E since 2009 when we bought our home. We are not in one of SDG&E's Public Power Safety Shut-off zones so we haven't dealt with...

As of June 1st SDG&E effectively changed the minimum amount I pay each month. Prior to June 1st the Non-bypassable charges (NBCs) were included in the minimum daily charge and I was paying ~$10 a month as I produce more than I use most every month. Now they treat NBCs as a separate line-item...

For SDG&E billing I'm 98.6% positive that the time period for NBCs is 15 mins. When I download the 15 min Green Button data from SDG&E, I can match exactly the NBC amounts each bill period by adding up the Net Energy (consumption - generated) for each 15 min increment where the Net Energy is...

You may want to model that using PvWatts ( PVWatts ) to see what, if any, additional energy production you can harvest. You will most likely see that it is nil, nada, nothing.

How are you going to charge that Powerwall? I doubt you could economically justify the cost of a Powerwall with that small of system, especially if you "expect" only covering 50% of your electrical use. That being said, there might be other reasons to have a Powerwall as a backup for anticipated...

I'm the SDG&E area and have had no problem from them with overproducing ~2,000kWh per year. They seem to be happy taking that excess power I produce and selling it to others at high rates while paying me about $0.04 per kWh at true up time.

According to our SDG&E smartmeter our house draws a total of 1.55kWh overnight (10PM to 5AM). We use gas for heat, hot water and cooking.

Here in sunny San Diego, actually Poway, my Dec-Jan average is 56% of my Jun-Jul average.

On my 4kW system the highest daily total I've seen this month is 28.61 kWh. Two days later, a very cloudy day here in Poway, CA I saw a mere 7.35kWh total. If my math is right that's ~75% reduction from a sunny day to a cloudy day.

All panels oriented at 190 degrees with no shade problems.

I have a very similar system down in the San Diego area - 12 335W panels(4.02kW) with a SolarEdge SE3800H-US inverter. At the end of today, my SolarEdge monitoring app shows a total of 25.18 kWh at the inverter with the panels totaling 25.31kWh. My numbers are much closer than yours. Have you...

25.99kWh today from my 4.02kW system in sunny San Diego (6.47kWh/kW)
