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.

SpaceX’s Starlink, the satellite internet program launched by Elon Musk’s company, has gotten its latest airline adoptee, offering stable and reliable internet to passengers.

Southwest Airlines announced on Wednesday that it would enable Starlink on its aircraft, a new strategy that will expand to more than 300 planes by the end of the year.

The company said it plans to “rapidly integrate Starlink into its fleet,” and that the first Starlink-equipped aircraft will enter service this Summer.

Tony Roach, Executive Vice President, Chief Customer and Brand Officer for the airline, said:

“Free WiFi has been a huge hit with our Rapid Rewards Members, and we know our Customers expect seamless connectivity across all their devices when they travel. Starlink delivers that at-home experience in the air, giving Customers the ability to stream their favorite shows from any platform, watch live sports, download music, play games, work, and connect with loved ones from takeoff to landing.”

Southwest also said that this is just one of the latest upgrades it is making to provide a more well-rounded experience to its aircraft. In addition to Starlink, it is updating cabin designs, offering more legroom, and installing in-seat power to all passengers.

Southwest became one of several airlines to cross over to Starlink, as reviews for the internet provider have raved about reliability and speed. Over the past year, Hawaiian Airlines, United Airlines, Alaska Airlines, airBaltic, Air France, JSX, Emirates, British Airways, and others have all decided to install Starlink on their planes.

This has been a major move away from unpredictable and commonly unreliable WiFi offerings on planes. Starlink has been more reliable and has provided more stable connections for those using their travel time for leisure or business.

Tesla nears closure of Full Self-Driving purchasing option

The move to bring FSD to this type of purchasing program comes after CEO Elon Musk noted in January that Tesla would move away from the outright purchase option.

Tesla is nearing the closure of its Full Self-Driving outright purchasing option, which will be removed on February 14, meaning Saturday will be the last time it can be bought as a non-subscription.

Tesla is aiming to move its Full Self-Driving suite to a subscription-only platform, a move that will enable people to only pay monthly for the semi-autonomous driving functionality.

The move to bring FSD to this type of purchasing program comes after CEO Elon Musk noted in January that Tesla would move away from the outright purchase option.

It is currently priced at $8,000 for the outright option to use Full Self-Driving, a substantial decrease compared to the $15,000 it was priced at one time. For the monthly subscription, it is just $99 per month, but that price will change, likely increasing as things get more advanced.

Tesla is overhauling its Full Self-Driving subscription for easier access

We say it will likely increase because there is no indication of how Tesla will price FSD. There has been some speculation that Tesla could utilize a tiered system to price FSD, which would potentially allow owners to pick and choose a set of features that would be most ideal for them.

This would potentially introduce an even more affordable option for FSD use, but this is unconfirmed. The reason many say this could be an option for Tesla is the fact that if the price goes up further, the take rate, which is currently around 12 percent at its most recent estimate, could be lower.

Musk needs 10 million active Full Self-Driving subscriptions to unlock one of the tranches of his newest compensation package.

The move to a subscription-only platform has its positives and negatives, and owners have been more than vocal about these since Musk confirmed the move.

Positives

  • Lower barrier to entry and higher potential adoption
  • Financially better for many users
  • Easier transfers and brand loyalty
  • Predictable recurring revenue for Tesla
  • Access to the latest features

Negatives

  • Higher long-term cost for loyal/long-term owners
  • No true “ownership” or permanence
  • Risk of future price hikes or even deactivation
  • Perceived as of less value
  • Impact on resale and used market

Overall, there is a split among the Tesla community in terms of what they see as the “right” way to handle this. Tesla is likely to shed more details on what its plans for the subscription-only platform will be, including pricing, in the coming weeks.

Elon Musk’s The Boring Company has been selected for a proposed underground transit system connecting Universal Orlando Resort and the newly opened Universal Epic Universe. 

The underground transport tunnel is designed to address the persistent gridlock surrounding International Drive. 

As noted in a blooloop report, Universal’s Shingle Creek Transit and Utility Community Development District approved a resolution showing its intent to designate The Boring Company as the contractor for the project. 

The agreement covers the full scope of the project, from the tunnel’s design, construction, and maintenance. The project has also been described in public documents as a “point-to-point innovative transportation” initiative with a 25-year agreement.

The proposed Boring Company tunnels would directly link Universal’s existing parks with Epic Universe, which sits roughly three miles away from Universal Orlando Resort. Today, buses are the only direct connection between the two destinations.

Project requirements were quite stringent. Bidders were required to demonstrate at least $75 million in bonding capacity, have a minimum of seven years of operational experience, and show prior delivery of a comparable project valued at $25 million or more within the past 15 years. The Boring Company, thanks in no small part to the Vegas Loop, meets these requirements.

The Orlando selection adds to The Boring Company’s growing portfolio of Loop-style systems. In Las Vegas, the Las Vegas Convention Center Loop has transported more than two million passengers in Tesla vehicles through underground tunnels since 2021. The greater Vegas Loop system is also under construction.

For now, residents in the area seem enthusiastic about the upcoming project. In a comment to Fox35, residents noted that the tunnels could improve traffic in the area.

“We are very congested at certain times and certain hours and that would certainly help with people not having to budget their time,” Mary Walters-Clark, a resident, stated. Another resident, Scott Heinz, echoed similar sentiments. “I think it would be a new opportunity to lessen traffic load and good for visitors as well,” he said.

The tunneling startup has started bringing its Loop projects to international locations. It recently signed a memorandum of understanding with Dubai’s Roads and Transport Authority to explore the development of a 17-kilometer underground Loop network beneath Dubai.
