SolarCity Struggles: What Tesla? (Part 1)

SolarCity reference from TeslaMotors.com
Shortly after ordering my Tesla Model S I contacted SolarCity, as referred through TeslaMotors.com, with the premise that I would be getting solar panels installed on my property. I wrote about the positive sales process that I experienced and wanted to round out the rest of the story through a multi-part series.
Background
I live on a horse farm in Massachusetts. We have one address, but two electric meters for accounting purposes. So, when I signed up for SolarCity I actually signed up twice – once for each meter.
We receive two plans with separate systems sized for the needs of each meter. The initial house plan was for a system to generate 24,000 kWh/year while the system for the farm would generate 21,000 kWh/year.
That’s where we left off with the sales process before moving onto the design process. That’s when things started to go sideways.
“What Tesla?”
Despite the fact that I signed up through the Tesla Motors site and mentioned several times I was getting a Tesla Model S, the additional energy usage was not considered in any of the planning. I was naïve at the time and hadn’t thought about how much the Tesla would actually affect my energy usage, and if you thought the SolarCity folks would be well-versed in this, they weren’t.
SolarCity knew little about what the Tesla Model S would consume in power.
When you initially sign up with SolarCity they collect all sorts of data from you. They collect a years worth of prior electricity bills; they perform a thorough site survey; they take 360 degree pictures from your roof, and they do a home energy assessment. In my case this was done twice since I had two meters across the properties. The design process sounds impressive but it was flawed.
The home energy assessment is generic and not very tailored to your exact situation. They provide generic advice about getting more efficient appliances and energy efficient bulbs and electronic devices, which to me was pure common sense. SolarCity’s break-even analysis was based off of those generic recommendations which, to me, made no sense. They also missed the fact I was getting a Tesla in all of the planning. My electricity usage was already high to begin with, and now with a Tesla Model S that would be seeing at least 30k miles a year, the Tesla would be a significant factor in my future energy use. It turned out that I needed about 30% more solar capacity to cover the Tesla.
After pointing this out to them and going through another round of engineering design rework, we ended up with a plan for a 37,000 kWh/year system for the house.
Commitment
Before I dive into the struggles that were encountered throughout the process, it’s important to note that my proposed system costs upwards of $170,000 distributed over 20 years, but with no upfront costs. One of the sales folks said the proposed combined system would be the largest residential system in New England.
All of this should have tipped me off to the troubles that would follow. But I figured with Elon Musk backing SolarCity and the company’s perception as the fastest growing full-service solar company, I was in good hands since they knew what they were doing. I was wrong.
More on SolarCity’s execution challenges in the part 2 of this series.

Tesla Full Self-Driving’s newest behavior is the perfect answer to aggressive cars
According to a recent video, it now appears the suite will automatically pull over if there is a tailgater on your bumper, the most ideal solution for when a driver is riding your bumper.
Tesla Full Self-Driving appears to have a new behavior that is the perfect answer to aggressive drivers.
According to a recent video, it now appears the suite will automatically pull over if there is a tailgater on your bumper, the most ideal solution for when a driver is riding your bumper.
With FSD’s constantly-changing Speed Profiles, it seems as if this solution could help eliminate the need to tinker with driving modes from the person in the driver’s seat. This tends to be one of my biggest complaints from FSD at times.
A video posted on X shows a Tesla on Full Self-Driving pulling over to the shoulder on windy, wet roads after another car seemed to be following it quite aggressively. The car looks to have automatically sensed that the vehicle behind it was in a bit of a hurry, so FSD determined that pulling over and letting it by was the best idea:
Tesla appears to be implementing some sort of feature that will now pull over if someone is tailgating you to let the car by
Really cool feature, definitely get a lot of this from those who think they drive race cars

We can see from the clip that there was no human intervention to pull over to the side, as the driver’s hands are stationary and never interfere with the turn signal stalk.
This can be used to override some of the decisions FSD makes, and is a great way to get things back on track if the semi-autonomous functionality tries to do something that is either unneeded or not included in the routing on the in-car Nav.
FSD tends to move over for faster traffic on the interstate when there are multiple lanes. On two-lane highways, it will pass slower cars using the left lane. When faster traffic is behind a Tesla on FSD, the vehicle will move back over to the right lane, the correct behavior in a scenario like this.
Perhaps one of my biggest complaints at times with Full Self-Driving, especially from version to version, is how much tinkering Tesla does with Speed Profiles. One minute, they’re suitable for driving on local roads, the next, they’re either too fast or too slow.
When they are too slow, most of us just shift up into a faster setting, but at times, even that’s not enough, see below:
What has happened to Mad Max?
At one point it was going 32 in a 35. Traffic ahead had pulled away considerably https://t.co/bjKvaMVTNX pic.twitter.com/aaZSWmLu5v

There are times when it feels like it would be suitable for the car to just pull over and let the vehicle that is traveling behind pass. This, at least up until this point, it appears, was something that required human intervention.
Now, it looks like Tesla is trying to get FSD to a point where it just knows that it should probably get out of the way.

Tesla Megapack powers $1.1B AI data center project in Brazil
By integrating Tesla’s Megapack systems, the facility will function not only as a major power consumer but also as a grid-supporting asset.
Tesla’s Megapack battery systems will be deployed as part of a 400MW AI data center campus in Uberlândia, Brazil. The initiative is described as one of Latin America’s largest AI infrastructure projects.
The project is being led by RT-One, which confirmed that the facility will integrate Tesla Megapack battery energy storage systems (BESS) as part of a broader industrial alliance that includes Hitachi Energy, Siemens, ABB, HIMOINSA, and Schneider Electric. The project is backed by more than R$6 billion (approximately $1.1 billion) in private capital.
According to RT-One, the data center is designed to operate on 100% renewable energy while also reinforcing regional grid stability.
“Brazil generates abundant energy, particularly from renewable sources such as solar and wind. However, high renewable penetration can create grid stability challenges,” RT-One President Fernando Palamone noted in a post on LinkedIn. “Managing this imbalance is one of the country’s growing infrastructure priorities.”
By integrating Tesla’s Megapack systems, the facility will function not only as a major power consumer but also as a grid-supporting asset.
“The facility will be capable of absorbing excess electricity when supply is high and providing stabilization services when the grid requires additional support. This approach enhances resilience, improves reliability, and contributes to a more efficient use of renewable generation,” Palamone added.
The model mirrors approaches used in energy-intensive regions such as California and Texas, where large battery systems help manage fluctuations tied to renewable energy generation.
The RT-One President recently visited Tesla’s Megafactory in Lathrop, California, where Megapacks are produced, as part of establishing the partnership. He thanked the Tesla team, including Marcel Dall Pai, Nicholas Reale, and Sean Jones, for supporting the collaboration in his LinkedIn post.

Starlink powers Europe’s first satellite-to-phone service with O2 partnership
The service initially supports text messaging along with apps such as WhatsApp, Facebook Messenger, Google Maps and weather tools.
Starlink is now powering Europe’s first commercial satellite-to-smartphone service, as Virgin Media O2 launches a space-based mobile data offering across the UK.
The new O2 Satellite service uses Starlink’s low-Earth orbit network to connect regular smartphones in areas without terrestrial coverage, expanding O2’s reach from 89% to 95% of Britain’s landmass.
Under the rollout, compatible Samsung devices automatically connect to Starlink satellites when users move beyond traditional mobile coverage, according to Reuters.
The service initially supports text messaging along with apps such as WhatsApp, Facebook Messenger, Google Maps and weather tools. O2 is pricing the add-on at £3 per month.
By leveraging Starlink’s satellite infrastructure, O2 can deliver connectivity in remote and rural regions without building additional ground towers. The move represents another step in Starlink’s push beyond fixed broadband and into direct-to-device mobile services.
Virgin Media O2 chief executive Lutz Schuler shared his thoughts about the Starlink partnership. “By launching O2 Satellite, we’ve become the first operator in Europe to launch a space-based mobile data service that, overnight, has brought new mobile coverage to an area around two-thirds the size of Wales for the first time,” he said.
Satellite-based mobile connectivity is gaining traction globally. In the U.S., T-Mobile has launched a similar satellite-to-cell offering. Meanwhile, Vodafone has conducted satellite video call tests through its partnership with AST SpaceMobile last year.
For Starlink, the O2 agreement highlights how its network is increasingly being integrated into national telecom systems, enabling standard smartphones to connect directly to satellites without specialized hardware.
