Installing Solar Panels through SolarCity

Published

on

Installing Solar Panels through SolarCityShortly 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

SolarCity Panel StagingIt 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

Solar Mounting PointsThe 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

Pipe out of placeTwo 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

Installing Solar Panels through SolarCityAfter 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

Solar InvertersI 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 Full Self-Driving expands to another European country

Published

on

Credit: Tesla

Tesla’s Full Self-Driving (Supervised) is heading to Czechia after the Czech Ministry of Transport recognised the Dutch RDW’s provisional type approval, making the country the seventh EU member state to clear the system for public roads. Tesla Europe announced on 21 September 2026 that “FSD Supervised is now approved in Czechia” and that rollout “will begin soon.”

The decision marks a notable reversal. Earlier in 2026, Prague had declined to automatically recognise the Netherlands’ April approval, citing concerns over speed-limit compliance, traffic-sign recognition and driver-attention monitoring, and arguing that a coordinated EU approach was preferable. Officials said months of expert review, talks with Tesla and other member states, and real-world data from countries already using the system resolved those issues.

“Safety remains the top priority,” the ministry stated.

FSD Supervised remains a Level 2 driver-assistance system: the driver must stay engaged and is legally responsible. Eligible vehicles need AI4, the company’s most up-to-date hardware version. Tesla is expected to push the feature over the air in the coming days, following the pattern seen after earlier national approvals.

Europe’s rollout began when Dutch regulator RDW issued a provisional EU type approval on 10 April 2026 after extensive testing. Mutual recognition then produced a rapid cascade: Lithuania (20 May), Estonia (29 May), Denmark (9 June), Belgium (10 June) and Slovenia (7 September). Czechia now completes that list of seven.

The approvals cover only a modest share of the EU population, but they add political weight ahead of a 6 October vote by the Technical Committee on Motor Vehicles. A qualified majority, at least 15 of 27 member states representing 65 percent of the EU population, could open the remaining markets, including large ones such as Germany, France, Italy and Spain that have so far preferred to wait for a bloc-wide decision.

For Czech Tesla owners, the immediate prize is access to the same supervised highway and city driving already available in the other six countries. For Tesla, each new market generates additional European driving data and strengthens the case that FSD Supervised can operate safely under the continent’s varied road rules. The Czech approval is therefore both a local milestone and another incremental step toward a wider European launch.

Tesla Roadster event requires restricted airspace, and the FAA obliges

Published

The Federal Aviation Administration (FAA) has established a Temporary Flight Restriction over SpaceX’s McGregor, Texas, rocket development and test facility, a move widely viewed as preparation for Tesla’s October 1 Roadster reveal. The restriction took effect September 18 and runs through October 2.

NOTAM FDC 6/3825 covers a 1.5-nautical-mile radius around the site near Waco and extends from the surface to 10,000 feet above ground level. The FAA cited hazards under 14 CFR 91.137(a)(3) and barred aircraft and drones from the zone. Tesla’s invitation to reservation holders already placed the event in Waco, about 20 minutes from McGregor, making the timing and location more than coincidental.

What stands out is the altitude. Typical recent TFRs at McGregor for engine static fires and component tests have used far lower ceilings, often around 2,000 feet. Raising the limit to 10,000 feet is unusually high even compared with some Starbase restrictions and signals operations that go beyond a standard ground-level engine test.

That extra airspace has fueled speculation about the long-promised SpaceX Package for the Roadster. Elon Musk has described cold-gas thrusters that could deliver sub-one-second 0-60 times and, more dramatically, brief lift-off. Reports earlier this year indicated Tesla planned a remote-controlled demonstration at McGregor in which the car would leave the ground with no one inside; spectators kept hundreds of yards away because of the noise.

The 10,000-foot envelope would give operators a large safety buffer even if the vehicle only hovers a short distance.

Tesla has not confirmed a flight demo. The company has only used the phrase “Go for launch” and posted a teaser image of the car on what looks like a launch pad. The TFR itself mentions only hazards. Still, closing airspace this high and this close to the reveal date strongly suggests the event will include more than a static display.

Whether the Roadster actually hovers on October 1 remains to be seen. What is certain is that the FAA has cleared a large vertical slice of Texas sky for whatever Tesla and SpaceX intend to show. Reservation holders heading to Waco will be among the first to find out if the car can do more than drive.

Elon Musk drops a surprise update on Boring Company’s next big dig

Musk says Boring Company could shrink the Austin to San Antonio drive to just minutes.

Published

By

Elon Musk says The Boring Company is working on what he called “a simple, precursor Hyperloop” tunnel connecting Austin and San Antonio, targeting speeds above 200 mph and cutting a drive that can take up to two and a half hours down to a consistent under 30 minutes. Musk posted the idea on X Sunday, in a reply to a repost of an AI generated video imagining a science fiction future with human colonies on other worlds, which he shared with the line “This is the future we shall bring into being.”


The Boring Company’s own account picked up the idea in the same thread, adding a detail about how the trip would actually work: “Because Loop/Hyperloop is express (i.e. no intermediate stops), one could travel from an Austin parking lot to a favorite San Antonio restaurant in about 30 minutes. As long as they both have Loop stations.” That framing ties the proposed intercity link to the same station model the company already runs in Las Vegas, where riders enter the tunnel network through small, garage style stops rather than one central terminal.

This is not the company’s first run at the Austin to San Antonio corridor. Boring Company floated tunnels between the two cities as far back as 2021, and later competed for a separate San Antonio Loop project tied to the airport before that specific bid stalled. Pitches for tunnels in Chicago, Los Angeles, and a New York to Washington corridor have followed a similar pattern of big announcement without a shovel in the ground.

What is different this time is the balance sheet, especially since The Boring Company closed a 3 billion dollar funding round led by investors in the United Arab Emirates earlier this month at a valuation near 23 billion dollars, giving the tunneling company more capital to chase speculative projects than it had during its earlier Texas pitches. The company is also mid-build on two other intercity systems it has actually broken ground on, inc;luding a Nashville tunnel linking downtown to the airport, where a second boring machine finished commissioning in June, and its Las Vegas network, where the station count keeps climbing on paper faster than tunnels get dug.

That gap between announcement and execution is the reason to treat Sunday’s post as an opening bid rather than a project. A tunnel spanning roughly 80 miles between two metro areas, running at speeds Boring Company has not demonstrated over any real distance, would dwarf anything the company has built. For now, the Austin to San Antonio Hyperloop exists as a caption under an AI generated space video.
