SolarCity Struggles: National Gridlock (Part III)
In this final post within my SolarCity Struggles series I’ll be outlining the additional complexities that surfaced after our local power company, National Grid, got involved.
National Grid-Lock
Having already experienced some delays on my solar project due to architectural redesigns, National Grid jumped into the mix to make things even worse by throwing up one road block after another. There was a conflict of interest for National Grid to assist on the project since we would be shifting more than $170,000 of revenue from them to SolarCity. I’d only see a tiny slice of that by way of my energy savings. Despite many city mandates to be “More Green”, the utility companies clearly have no interest in assisting customers to go solar since it would be counter productive for them.
Roadblock #1
National Grid would not allow “net metering” (where you can re-supply energy through solar power) for two different meters at the same address. SolarCity stepped up and offered to join my two meters and upgrade my panel (from 400A to 600A) in order to support net metering. Accounting issues aside, I agreed to the proposed change and moved forward with yet another site visit that would lead to an engineering redesign.
Roadblock #2
Having (verbally) moved past this, National Grid then reported that the transformer for my area was only capable of handling 23kW of generated power and could not support SolarCity’s proposed 56kW system. This was by the most serious setback since it would require a design that would cut my generation down to 23kW or less. This meant dropping the farm completely and scaling the house from 35kW to 23kW.
A 23kW design called for the front of my house to have solar panels while only a portion of the rear of the house would be retrofitted with panels. This would have looked really odd so we decided to scale back the design to a 18kW system and only include panels on the front of the house.
National Grid informed me that the transformers support between 8 – 12 houses in my area so any neighbors that undergo a solar project will be limited to the remaining 5kW that the transformer can support.
Next Steps
Going from a 56kW to 18kW (a 68% drop in planned production) system will reduce my energy coverage to 32% of my power needs through solar. This is unfortunately the case due to National Grid’s limitation despite my property having enough roof surface to generate 100% of my energy needs.
I will save approximately $56,000 over the next 20 years with this smaller set up, a far departure from the original projected savings of $105,000 but still worth pursuing.
A friendly note from SolarCity arrived on September 1st letting me know that my installation was scheduled for December 8th and 9th because of the magnitude of the project. Considering this 18kW system is a third of what would have been, I couldn’t help but wonder how SolarCity would have handled the original plans. I can’t imagine starting this project in the dead of a New England winter. SolarCity indicated that the project would require 4-6 weeks before the “go live” date which meant I wouldn’t be completing until January 2015. That puts the project at about 10 months from start (initial consultation) to finish and assuming all goes well from here on out.
Summary
SolarCity has made a number of mistakes on this project since the beginning; from improperly sizing the system to not knowing the requirements and restrictions of the local power company; to not following owner requests on layout; to not understanding power generation limits imposed by the power company.
My experience with SolarCity has led me to conclude that they’re not ready for widespread adoption outside of key markets and have a lot of work and learning to do before they will be ready for that next stage of growth.
I truly hope the project moves forward. My next updates will be on the post installation experience which will hopefully take place sometime between now and the end of this year. Stay tuned.

Elon Musk dismissed reports claiming SpaceX had placed a massive order for NVIDIA GPUs worth $52 billion. The denial came hours after Taiwanese media, citing unnamed industry sources, reported that SpaceX planned to acquire approximately 13,000 AI server racks, equating to roughly 1 million GB300 GPUs, from Foxconn.
Each rack was estimated at around $4 million, with deliveries potentially starting in late 2025.
The story suggested this would mark SpaceX’s first major foray into Foxconn-manufactured NVIDIA hardware, breaking from suppliers like Supermicro and Dell. Musk responded bluntly on X:
This is fake news
— Elon Musk (@elonmusk) July 20, 2026
Despite the denial, the rumored scale aligns with SpaceX’s explosive growth in AI infrastructure. NVIDIA’s GB300 (successor to the GB200 NVL) racks deliver unprecedented performance for large-scale training and inference. A $52 billion commitment would dwarf most corporate AI budgets and provide the compute muscle needed for frontier models.
SpaceX already operates gigawatt-scale terrestrial clusters like Colossus in Memphis, Tennessee, and has monetized them aggressively through leasing deals.
SpaceX’s newest Starmind will make earth data centers obsolete
Major customers include Anthropic (paying ~$1.25 billion monthly for 220,000+ GPUs), Google (~$920 million monthly for 110,000 GPUs), and Reflection AI. These arrangements are projected to generate tens of billions in annual revenue, far outpacing traditional SpaceX businesses.
Such an investment would fuel internal AI efforts, particularly Grok models under the integrated SpaceXAI division, while supporting ambitious orbital data center plans. SpaceX envisions launching thousands of AI-optimized satellites powered by solar energy and cooled in space, bypassing terrestrial power and land constraints.
This “Starmind” constellation could position the company as a leader in space-based computing.
SpaceX as an Emerging AI Powerhouse
Once primarily known for reusable rockets and Starlink satellite internet, SpaceX has transformed into a multifaceted AI player.
The 2026 acquisition of xAI integrated Grok development directly into the company. Starlink’s low-latency global network complements massive compute clusters, enabling efficient data flow for training and serving AI models.
Musk has long argued that AI scaling demands solutions beyond Earth, citing things like real estate and electricity limits on the ground.
While the Foxconn deal may not be in the cards, SpaceX’s trajectory is continuing on the path of blending aerospace engineering with hyperscale AI to dominate both launches and intelligence infrastructure.
Elon Musk shed more details on the upcoming improvements to Tesla’s Full Self-Driving suite, specifically one that the CEO mentioned last week, which should help owners see fewer interventions.
Last week, Musk hinted that one major improvement that Tesla planned to roll out to Full Self-Driving users was the car’s ability “to remember your specific interventions and match each person’s individual preferences.”
Elon Musk says your Tesla will start to learn your individual preferences
This small bit of detail was linked to a post from Tesla community member Whole Mars, who said that FSD’s tendency to exit the carpool lane, a feature that owners can turn on but at times the car will disregard.
It sounds like, based on Musk’s two responses since that original post, it is safe to say the things FSD will start to remember are wide-ranging. However, it seems the biggest differences will be noticed with parking performance, which Musk continues to mention.
Highway Lane Preferences
The initial post Musk mentioned, with these new remembered preferences soon to arrive for Tesla owners everywhere, was the Carpool/Express Lane.
Tesla has a setting in the FSD menu that lets drivers enable HOV Lane travel. However, the car won’t always stay in that suggested or preferred lane.

Some owners have also complained of left lane camping, an illegal maneuver in at least some states. Cruising in the passing lane has resulted in tickets for some, as it is illegal in over 30 states in the U.S.
Tesla did not confirm if these preferences would also be included in new FSD behaviors, but it would certainly help move the company toward fewer interventions.
Parking Preferences
This seems to be the real focus of the entire operation, as Musk stated several weeks ago that parking was overwhelmingly the most frequent reason for interventions.
The major issue with parking is not necessarily the parking “performance,” as FSD is generally good at parking. It definitely has its issues; we’ve recorded plenty of them, including this one as recent as last week:

However, the changes coming are more about preferences, meaning where you park and how your car enters the spot, either pulling in or backing in. Owners have also reported that pulling into the correct driveway is a relatively rare thing for FSD, something else that needs to be confronted.
Musk basically confirmed that all of these things would be part of Tesla’s plan to address driver preferences with FSD:
Yes
— Elon Musk (@elonmusk) July 20, 2026
It’s obvious there is something big coming with FSD, and the company’s focus seems to be eliminating any intervention that would be related to preferences. This is probably the biggest bottleneck between Tesla and being fully autonomous. Critical interventions do occur, but they are much less frequent.
The only time a driver should be taking over is because of a critical intervention; this seems to be the goal of Tesla right now.
This all seems to be a priority as Tesla continues to move closer to the prospect of unsupervised driving.
Elon Musk said today on X that Teslas will start to learn your individual preferences. This is something that he seemed to hint toward earlier this month when he said parking was by far the biggest reason drivers intervene with Full Self-Driving.
Musk made the comment in response to notable Tesla influencer Whole Mars, who said that his vehicle will sometimes disobey the settings he has enabled for his car. He responded to the post, stating that “The car will start to remember your specific interventions and match each person’s individual preferences.”

This is something that could be perhaps one of the biggest ways Tesla could minimize or even work closer toward eliminating interventions altogether. While FSD does a lot of things really well, many people intervene a vast majority of the time not due to major or critical safety errors.
Instead, many take over because the car is doing something that they do not like as a preference; it might park in a parking spot that is not preferred by the driver, it might linger too long in the left lane on the highway (a personal favorite), or it could even take a route that the driver does not like.
These all lead to interventions, but they are not triggered by a major safety issue. Instead, it’s just preference.

Tesla Full Self-Driving v14.3.5 Early Impressions: new features and early performance
If Teslas could start to learn the personal preferences of the person who owns them, interventions will truly begin to be less frequent. Some of this is already pretty evident, in my opinion. Teslas use a neural network to learn behaviors and accumulate data to improve performance.
For months now, we’ve tracked FSD’s performance at “Except Right Turn” stop signs, something that is very common in Pennsylvania, but many of our readers located in other parts of the U.S. have never heard of. FSD handles one Except Right Turn stop sign very well, one that I travel past frequently. Others that I do not navigate through as often do not have as confident a performance. It seems like the cars might already be doing this to an extent.

That example is also for something that is a street sign and not necessarily a driver preference; however, I still feel it is worth mentioning because it only handles that commonly passed Except Right Turn stop sign with true confidence. Others it still seems to struggle with.
This could be one of Tesla’s big moves toward full autonomy, and it could be a pathway to truly unsupervised driving. Every day, millions of cars on the road travel at a human driver’s personal preferences with no incident. Why can’t autonomous vehicles still cater to a passenger’s preferences while being autonomous? Tesla seems to have the idea that it would be possible.
