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.

Tesla rolls out most aggressive Model Y lease deal in the US yet
With the promotion in place, customers would be able to take home a Model Y at a very low cost.
Tesla has rolled out what could very well be its most aggressive promotion for Model Y leases in the United States yet. With the promotion in place, customers would be able to take home a Model Y at a very low cost.
Zero downpayment leases
The new Model Y lease promotion was initially reported on X, with industry watcher Sawyer Merritt stating that while the vehicles’ monthly payments are still similar to before, the cars can now be ordered with a $0 downpayment.
Tesla community members noted that this promotion would cut the full payment cost of Model Y leases by several thousand dollars, though prices were still a bit better when the $7,500 federal tax credit was still in effect. Despite this, a $0 downpayment would likely be appreciated by customers, as it lowers the entry point to the Tesla ecosystem by a notable margin.
Premium freebies included
Apart from a $0 downpayment, customers of Model Y leases are also provided one free upgrade for their vehicles. These upgrades could be premium paint, such as Pearl White Multi-Coat, Deep Blue Metallic, Diamond Black, Quicksilver or Ultra Red, or 20″ Helix 2.0 Wheels. Customers could also opt for a White Interior or a Tow Hitch free of charge.
A look at Tesla’s Model Y order page shows that the promotion is available for all the Model Y Premium Rear-Wheel Drive and the Model Y Premium All-Wheel Drive. The Model Y Standard and the Model Y Performance are not eligible for the $0 downpayment or free premium upgrade promotion as of writing.

Tesla is looking to phase out China-made parts at US factories: report
Tesla has reportedly swapped out several China-made components already, aiming to complete the transition within the next two years.
Tesla has reportedly started directing its suppliers to eliminate China-made components from vehicles built in the United States. This would make Tesla’s US-produced vehicles even more American-made.
The update was initially reported by The Wall Street Journal.
Accelerating North American sourcing
As per the WSJ report, the shift reportedly came amidst escalating tariff uncertainties between Washington and Beijing. Citing people reportedly familiar with the matter, the publication claimed that Tesla has already swapped out several China-made components, aiming to complete the transition within the next two years. The publication also claimed that Tesla has been reducing its reliance on China-based suppliers since the pandemic disrupted supply chains.
The company has quietly increased North American sourcing over the past two years as tariff concerns have intensified. If accurate, Tesla would likely end up with vehicles that are even more locally sourced than they are today. It would remain to be seen, however, if a change in suppliers for its US-made vehicles would result in price adjustments for cars like the Model 3 and Model Y.
Industry-wide reassessments
Tesla is not alone in reevaluating its dependence on China. Auto executives across the automotive industry have been in rapid-response mode amid shifting trade policies, chip supply anxiety, and concerns over rare-earth materials. Fluctuating tariffs between the United States and China during President Donald Trump’s current term have made pricing strategies quite unpredictable as well, as noted in a Reuters report.
General Motors this week issued a similar directive to thousands of suppliers, instructing them to remove China-origin components from their supply chains. The same is true for Stellantis, which also announced earlier this year that it was implementing several strategies to avoid tariffs that were placed by the Trump administration.

Tesla owners propose interesting theory about Apple CarPlay and EV tax credit
“100%. It’s needed for sales because for many prospective buyers, CarPlay is a nonnegotiable must-have. If they knew how good the Tesla UI is, they wouldn’t think they need CarPlay,” one owner said.
Tesla is reportedly bracing for the integration of Apple’s well-known iOS automotive platform, CarPlay, into its vehicles after the company had avoided it for years.
However, now that it’s here, owners are more than clear that they do not want it, and they have their theories about why it’s on its way. Some believe it might have to do with the EV tax credit, or rather, the loss of it.
Owners are more interested in why Tesla is doing this now, especially considering that so many have been outspoken about the fact that they would not use it in favor of the company’s user interface (UI), which is extremely well done.
After Bloomberg reported that Tesla was working on Apple CarPlay integration, the reactions immediately started pouring in. From my perspective, having used both Apple CarPlay in two previous vehicles and going to Tesla’s in-house UI in my Model Y, both platforms definitely have their advantages.
However, Tesla’s UI just works with its vehicles, as it is intuitive and well-engineered for its cars specifically. Apple CarPlay was always good, but it was buggy at times, which could be attributed to the vehicle and not the software, and not as user-friendly, but that is subjective.
Nevertheless, upon the release of Bloomberg’s report, people immediately challenged the need for it:
Everyone thinks they need it. I would think that too if I didn’t know how good Tesla’s interface was. CarPlay is a crappy layer on top of crappy info-navs, and people think it’s an imperative because it provides a level of consistency from car to car. They have no clue how much…

How can it not be when the best engineers choose Tesla over Apple and Tesla’s core focus is auto vs Apple being mobile. It’s what Tesla does every day. It’s a side project for Apple. Still Apple is much better than any other auto OEM who attract lesser talent and make digital…

Some fans proposed an interesting point: What if Tesla is using CarPlay as a counter to losing the $7,500 EV tax credit? Perhaps it is an interesting way to attract customers who have not owned a Tesla before but are more interested in having a vehicle equipped with CarPlay?
“100%. It’s needed for sales because for many prospective buyers, CarPlay is a nonnegotiable must-have. If they knew how good the Tesla UI is, they wouldn’t think they need CarPlay,” one owner said.
Tesla has made a handful of moves to attract people to its cars after losing the tax credit. This could be a small but potentially mighty strategy that will pull some carbuyers to Tesla, especially now that the Apple CarPlay box is checked.
