Solar Installation Day



They're here.


Looks like the solar panels were designed in Germany.

9:30 south slope:

9:30 west slope:

9:30 north wall, the PowerWall is behind the orange ladder:

2:00 south slope - Panel installers finished and left.

2:00 west slope

2:00 north wall. CenterPoint (manages grid) is onsite, they had to pull the meter for the electricians.


4:20 south slope - I drug a ladder out so I could get a better photo of the south roof, was up against my neighbor's house for this shot. The original plan called for 6 rows with some gaps for vent pipes over the master bath. They were able to work around those and clean up the arrangement.


4:20 north wall - Electricians are finished, new sticker on the meter lets power company linemen know there's other sources of power besides the grid.



Test of the PowerWall.

Everything's now in standby mode until the System Inspection and Utility Inspection are done. Could be a month or so for that.

Guess I need a new bumper sticker:

Didn't know the PowerWall had mood lighting!

2:00 - panel installers are finished & have left. Electricians are still hard at work - CenterPoint (manages grid) is onsite, they removed my meter (so power's out) so the electricians can finish that part of the install.

Powerwall is the inverter, or is that Tesla's home battery? I looked into SolarCity a few years back, but the savings vs all the restrictions didn't seem worthwhile. I figured I'd wait until the home battery scene picked up or the cost went down.

Received an email update this morning:




This is to inform you that an application has been received for a distributed generation connection at the subject address. It has been moved to Inspection In Progress. Detailed information for the location is provided below.


Customer Name: DARRELL SPICE

Address: xxxx

Contact #:xxxx

Generation Type: Inverter

Fuel Source: Solar

Generation Size AC: 10.71

Comments: Please upload the installation photos


Power Quality & Solutions, DER Team will perform the normal review process to ensure compliance with Texas PUC rules and CNP requirements.


Please feel free to contact us if there are any questions or concerns.

I was under the impression they'd be coming out for the final inspection, but by the comment that may not be the case.

How long is the Powerwall supposed to provide power? I'm guessing it's for essentials only? (Lights, fridge, computer, etc.)

Tesla has an interactive tool How long will PowerWall last in an outage?. Based on that, essentials only for almost 2 days. Solar will refill it during the day, so in theory indefinitely.

Each PowerWall can supply 240V @ 30 amps and I only have one. The breakers for my AC and Model 3 are 240v @ 40 amps and 50 amps respectively, so were relocated to a new breaker box which does not get supplied during a power outage.

I could have added a 2nd PowerWall and had enough to run everything, but decided it would be more cost effective to get something like this portable AC unit which runs off 120 volt. It'd be enough to keep my bedroom cool enough for sleeping, during the day I could cope with fans. Likewise I could plug my Model 3 into a 120 volt outlet, as I did for the first 6 months I had it.

Hadn't heard anything so I reached out to Tesla last week. Response was "we are reviewing your documents prior to submitting to CenterPoint". Sounds like somebody forgot to upload them, shouldn't take 2+ weeks to review them.

Reached out again yesterday, received back from somebody else "Thanks for the prompt. Eddy can you process this today?". A few hours later CenterPoint sent out an update "It has been moved to Inspection Submitted."

Received an update about 30 minutes ago, "It has been moved to Agreement Generated." with comments of "Please notify the customer that inspection has passed for this project and all that remains to proceed is a signed ICA. The ICA should be available for e-signature in the customer's e-mail."

I'm guessing ICA is something like InterConnect Agreement, will know for sure whenever it shows up.

Hadn't received it by 10:30 so contacted them, they had a SNAFU with their outgoing email server. Agreement showed up a little after 11, I signed it soon after using my iPad.

Received an update 1, status is now "It has been moved to Agreement Executed" with comments of "Moving from 'Agreement Generated' to 'Send Agreement for e-Signature' by ANB team."


So now I'm waiting on the ANB team.

Permission to operate received, though it's "as of Friday 26 April 2019", so I get to turn everything on tomorrow.
