Installing Solar Panels through SolarCity
Shortly after placing my order for my Tesla Model S I started looking into installing a solar panel system at home as a way to offset the soon-to-be increased electricity bill. My research turned me to a SolarCity system which I ended up signing up with in April of 2014.
After a number of scoping, design, and utility company challenges the day finally came for installation.
Sizing the Job
While I had originally hoped for a much larger system, the system that was installed was still large by most people’s standards. The final design called for 70 panels, each capable of generating 255W for a total of 17.8 kW and an annual expected output of 18,611 kWh.
To put that into perspective, my Model S uses an average of 775 kWh (as measured through a digital submeter) or approximately 2,400 miles. That usage will climb a bit for the winter months, but I still intend to use about 9,300 kWh per year for my Model S which equates to 50% of my expected solar generation capacity.
What this means is that I’ll be driving my Model S on 100% solar generated energy and still have solar energy to spare to offset my normal electric costs.
Many installations are half this size or smaller due to a number of constraints. Because of the size of this job, SolarCity booked 2 days for the install and sent a crew of about 8 to do the work.
Scheduling
It was a bit nerve wracking waiting for the project to begin 8 months after my April sign up date. This put us smack dab in the middle of winter for a December 8th install in New England. We’ve had snow and ice storms along the way which made me more skeptical that the install would ever take place.
I’m happy to report that the entire SolarCity team in charge of the project arrived on the scheduled date. They were late due to leftover work at a different site, but they turned up despite the wet weather, 30 degree temperature and got right to work. It was immediately evident that this crew knew what they were doing and it was just another day on the job despite the magnitude of the install.
Solar Panel Installation
The first order of business was to tape off and secure the area from foot traffic. Anchors are attached to the roof which the crew secured their safety harnesses to.
Once the precautionary safety measures were in place, the crew began setting up dozens of anchor points across the roof surfaces later to be used as mounting points for the solar panels. That part took most of the first day.
By the end of the first day they had managed to install solar panels on the smaller of the 2 roof lines and had most of the anchors ready on the larger roof line.
Weather Proof Guarantee
A Noreaster hit right in the middle of the week so installation was postponed. To make matter worse, all of the heavy rain and cold weather ended up icing over the roof. I crawled into both attics below each roof to ensure that all of the nails and anchors on the roof didn’t create a leak and was relieved to find that everything was totally dry.
SolarCity guarantees a leak-free installation so it was great to be able to validate that even after torrential rains.
The crew returned on the third day despite the rain and proceeded to work a full day in extremely cold weather and light rain.
Uh oh, Design Challenges
Two different design issues were uncovered during the solar panel installation. The first of which was related to a misjudgment on the number of solar panels that would fit. Designers back at corporate had mapped out 70 panels for the roof, but one of the panels would not fit behind the chimney. The crew offered to stick it somewhere else, but we declined as it would have been asymmetrical anywhere else and the aesthetics would not have been good. So we ended up with a total of 69 panels and a slight decrease in target generation capacity.
The second issue was identified on the third day. While the entire install was on the front of the house (thanks to National Grid), they had a pipe running in the middle of the roof on the rear of the house which looked stupid and unnecessary.
I spoke to them about it and they cheerfully redesigned and relocated the entire pipe. In the rain. In 30 degree weather. On top of the house. The install team took our concerns seriously and took care of the problem.
The Final Touches
After lugging the panels up all day (each panel weighs about 45 pounds) and mounting them, they took the time to level each of them so they were completely flat.
At one point a single panel in the middle of the lot was a bit out of place (not perfect) so one of the guys had to slide down the wet, cold, glass on his knees (getting soaked in the process), 30 feet above ground with just a line to keep him safe just to adjust the angle slightly. Those installers are hard core!
Electric Connection
I was surprised that SolarCity needed no access to the house (other than for bathroom breaks) to do the job. The entire connection for my house was on the outside. They needed to cut the power for about 45 minutes to connect into the mains but otherwise there was very little disruption.
The size of the installation required 3 inverters which they placed on the side of the house.
Next Steps
The process leading up to the install (3 part series) was frustrating and error-prone between the reluctant power company and the mistakes made by the out-of-touch engineers back at SolarCity corporate. But SolarCity’s installation team was nothing but first class, all the way. They knew their stuff, were very safety conscious and worked through some harsh conditions to get the job done, and done well. They restored my confidence in the decision I made and I’m confident again that things are going to work out well.
Now that the system is installed and ready to go we need to have the inspections done. SolarCity coordinates it all, but there’s a building inspection, an electrical inspection and then an inspection by the power company. Once all passes (in about 3-4 weeks) we’re given the green light to flip the switches and start putting that free energy from the sun to good use.

Tesla VP explains latest updates in trade secret theft case
Tesla reportedly caught Matthews copying the tech into machines that were sold to competitors, claiming they lied about doing so for three years, and continued to ship it. That is when Tesla chose to sue Matthews in July 2024 in Federal court, demanding over $1 billion in damages due to trade secret theft.
Tesla Vice President Bonne Eggleston explained the latest updates in a trade secret theft case the company has against a former manufacturing equipment supplier, Matthews International.
Back in 2024, Tesla had filed a lawsuit against Matthews International, alleging that the firm stole trade secrets about battery manufacturing and shared those details with some of Tesla’s competitors.
Early last year, a U.S. District Court Judge denied Tesla’s request to block Matthews International from selling its dry battery electrode (DBE) technology across the world. The judge, Edward Davila, said that the patent for the tech was due to Matthews’ “extensive research and development.”
The two companies’ relationship began back in 2019, as Tesla hired Matthews to help build the equipment for its 4680 battery cell. Tesla shared confidential software, designs, and know-how under strict secrecy rules.
Fast forward a few years, and Tesla reportedly caught Matthews copying the tech into machines that were sold to competitors, claiming they lied about doing so for three years, and continued to ship it. That is when Tesla chose to sue Matthews in July 2024 in Federal court, demanding over $1 billion in damages due to trade secret theft.
Now, the latest twist, as this month, a Judge issued a permanent injunction—a court order banning Matthews from using certain stolen Tesla parts or designs in their machines. Matthews is also officially “liable” for damages. The exact amount would still to be calculated later.
Bonne Eggleston, a VP for Tesla, said on X today that Matthews is a supplier who “exploited customer IP through theft or deception,” and has no place in Tesla’s ecosystem:
Buyer beware: Matthews International stole Tesla’s DBE technology and is now subject to an injunction and liable for damages.
During our work with Matthews, we caught them red-handed copying our technology—including proprietary software and sensitive mechanical designs—into… https://t.co/Toc8ilakeM

Tesla calls this a big win and warns other companies: “Buyer beware—don’t buy from thieves.”
Matthews hit back with a press release claiming victory. They say an arbitrator ruled they can keep selling their own DBE equipment to anyone and rejected Tesla’s request for a total sales ban. They call Tesla’s claims “nonsense” and insist their 20-year-old tech is independent. Both sides are spinning the same narrow ruling: Matthews can sell their version, but they’re blocked from using Tesla’s specific secrets.
What are Tesla’s Current Legal Options
The case isn’t over—it’s moving to the damages phase. Tesla can:
- Push forward in court or arbitration to calculate and collect huge financial penalties (potentially $1 billion+ if willful theft is proven).
- Enforce the permanent injunction with contempt charges, fines, or even jail time if Matthews violates it.
- Challenge Matthews’ new patents that allegedly copy Tesla’s work, asking courts to invalidate them or add Tesla as co-inventor.
- Seek extra damages, lawyer fees, and possibly punitive awards under the federal Defend Trade Secrets Act and California law.
Tesla could also refer evidence to federal prosecutors for possible criminal trade-secret charges (rare but serious). Settlement is always possible, but Tesla’s fiery public response suggests they want full accountability.
This isn’t just corporate drama. It shows why trade secrets matter even when Tesla open-sources some patents, confidential know-how shared in trust must stay protected. For the EV industry, it’s a reminder: steal from your biggest customer, and you risk losing everything.

Tesla Cybercab includes this small but significant feature
The Cybercab is Tesla’s big plan to introduce fully autonomous ride-sharing in a seamless fashion. In fact, the Full Self-Driving suite was geared toward alleviating the need to manually drive vehicles.
Tesla Cybercab manufacturing is strikingly close, as the company is still aiming for an April start date. But small and significant features are still being identified for the first time as production units appear all over the country for testing and for regulatory events, like one yesterday in Washington, D.C.
The Cybercab is Tesla’s big plan to introduce fully autonomous ride-sharing in a seamless fashion. In fact, the Full Self-Driving suite was geared toward alleviating the need to manually drive vehicles.
This was for everyone, including the disabled, who are widely reliant on ride-sharing platforms, family members, and medical shuttles for transportation of any kind. Cybercab aims to change that, and Tesla evidently put a focus on those riders while developing the vehicle, evident in a small but significant feature revealed during its appearance in the Nation’s Capital.

Tesla has implemented Braille within the Cybercab to make it easier for blind passengers to utilize the vehicle. On both the ‘Stop/Hazard Lights’ button and the Door Releases, Tesla has placed Braille so that blind passengers can navigate their way through the vehicle:

We have braille on the interior door releases as well

This is a great addition to the Cybercab, especially as Full Self-Driving has been partially pointed at as a solution for those with disabilities that would keep them from driving themselves from place to place.
It truly is a great addition and just another way that Tesla is showing they are making this massive product inclusive for everyone out there, including those who have not been able to drive due to not having vision.
The Cybercab is set to enter mass production sometime in April, and it will be responsible for launching Tesla’s massive plans for an autonomous ride-sharing program.

It is the latest move by a Musk company to automate, streamline, and reduce the manual, monotonous, and tedious work currently performed by humans through AI and robotics development. Digital Optimus will be capable of processing and actioning the past five seconds of a real-time computer screen video and keyboard and mouse actions.
Essentially, it will be an AI version of a desk worker in many capacities, including accounting, HR tasks, and others.
Musk said:
“Grok is the master conductor/navigator with deep understanding of the world to direct digital Optimus, which is processing and actioning the past 5 secs of real-time computer screen video and keyboard/mouse actions. Grok is like a much more advanced and sophisticated version of turn-by-turn navigation software. You can think of it as Digital Optimus AI being System 1 (instinctive part of the mind) and Grok being System 2. (thinking part of the mind).”
Its key applications would be used for enterprise automation, simulating entire companies, high-volume repetitive tasks, and potentially, future hybrid use with the Optimus robot, which would handle physical tasks, while Digital Optimus would handle the clerical work.
The creation of a digital AI suite like Digital Optimus would help companies save time and money, as well as become more efficient in their operations through massive scalability. However, there will undoubtedly be concerns from people who are skeptical of a fully-integrated AI workhorse like this one.
From an energy consumption perspective and just a general concern for the human workforce, these types of AI projects are polarizing in nature.
However, Digital Optimus would be a great digital counterpart to Tesla’s physical Optimus robot, as it would be a hyper-efficient addition to any company that is looking for more production for less cost.
Musk maintains that there is no other company on Earth that will be able to do this.
