My journey with a SolarCity System: Snow, Net Metering

Published

on

After 9 months of planning, waiting and negotiating, my SolarCity system installation was finally completed in December of 2014. Following the install, the only steps that remained were to implement updates required for net metering and to finalize the electrical and building inspections.

Net Meter

The electrical inspection went quickly, but the building inspection was a pain. The local building inspector wasn’t very responsive and scheduled inspections shortly after large snow storms, but then refused to do the inspection due to “snow covering the panels”.

While we waited for the inspections, which finally took place in March of 2015, National Grid installed a new Net Meter. Net meters are capable of monitoring the amount of power being sent back into the grid. The meter swap is quick work, but be forewarned that it requires power to be cut from your home during the swap.

Snow on panels

Weathering the Storm

We had a brutal Winter here in the Northeast and this was my first year with panels. So I had concerns about the impact of the heavy snow being on top of the panels, and also how one goes about cleaning off the snow. I asked SolarCity about proper handling and they told me not to worry about it:

We understand your concern with the snow and the load that it would cause. Please be advised that when your system was built, our engineers took into consideration, your roof structure as well as the amount of weight that it would be able to hold. We also have the system approved by the City for load bearings.The City and our engineers did take into consideration, the amount of largest amount of snow that your roof can withstand before we installed. I understand that there was a mass message out to all the people in the area advising them to make sure that they clear the roof. We advised that you allow the snow to melt/slide down on its own., If you are hiring someone to come out to clear the roof. Make sure that they be careful and they only sweep the panels.”

I patiently waited for the snow to slide off the panels and sure enough it did, and with no issues. The snow slides off the black, wet glass-like surface of the solar panels. You definitely don’t want to be anywhere below the roofline when the snow decides to let go!

Early Issues – Broken Gear

Solar InverterOnce National Grid completed the net metering install, I was finally approved to turn on the system. The first step involves turning a big dial (on each inverter) from off to on. I have three inverters which means three dials to flip on.

I turned each of them on. Two lit green almost immediately while the remaining inverted displayed a red fault light. There were no instructions on what to do in this scenario; no manuals and no guidance, so my only option was to call for help.

Getting help from SolarCity on the issue at had was a frustrating experience. SolarCity has a lot to learn when it comes to customer service. I spoke to several customer support managers as I continued to escalate my issue.

Finally, after five weeks of follow ups and many phone calls, I got the broken inverter fixed.

Tip:

SolarCity doesn’t bother to tell you this, but what I discovered was a little black button in the middle of the inverter. It’s hard to see but if you press the button you’ll be able to cycle through messages on the digital display, one of which is a fault code. Providing SolarCity with a fault code is much more useful than just letting them know that a red light is blinking.

Early Issues – Snow Fall

As mentioned earlier, snow doesn’t stick to the panels for long, but it does manage to build up before it lets go. Imagine 3 feet of heavy snow mixed with ice over your entire roof all letting go at the same time. It’s not a slow drip. It’s an avalanche.

The end result is dead flowers, dead bushes, and broken branches on vegetation immediately below the roof. As much as it’s common sense that snow will eventually melt from a roof and slide down, I wish SolarCity would have warned us that snow tends to slide from solar panels at a much quicker rate. I would have done something to fortify those flowers and bushes. After all, landscaping is not cheap.

There’s an accident waiting to happen so I think it’s in SolarCity’s best interest to pre-warn people of this, especially newbies to the world of solar panels.

Summary

Solar GenerationEleven months after starting the project, my SolarCity system finally went live (partially) on February 23, 2015.  And on April 1, 2015, the third inverter was fixed allowing the system to work in its full capacity.

The image to the right  is showing the day when the transformer on my street blew up and the entire street lost power for several hours. I added 33% more power from my large system going back into the network while using very little (Winter time) the same day the transformer blew. But then again, it was also April 1. Nobody made a fuss — National Grid replaced the transformer and all has been stable since. My best guess as to why that happened? Perhaps the transformer was already near its thresholds and my solar installation was the one to tip it over?

I’ll be writing about system monitoring, cost savings and billing errors in upcoming posts. The story isn’t over yet.

Tesla Cybercab improvements are already on the minds of company engineers

Published

on

Tesla Cybercab might have just rolled out to the public as it entered the company’s Robotaxi suite in Austin this past week. However, the vehicle might already be on its way to becoming even better, as the company is asking riders to describe what they’d like to see improved with the Cybercab.

Tesla sent a rider experience survey to Cybercab passengers only days after paid rides began in Austin. The questionnaire asks how satisfied riders were with the overall trip. Then it requests star ratings for availability and wait time, door functionality, vehicle touchscreen, mobile app experience, seat comfort, interior space, ride comfort, cleanliness, and cargo space.

A later section asks which features riders would most like to have and allows selection of up to three items from a list that includes heated seats, ventilated seats, fully reclining seats, a tray table, a wireless phone charger, a better sound system, and more storage. Respondents may also choose none of these or write in another idea. The survey closes with a recommendation score from zero to ten.

This rapid request for input illustrates Tesla’s habit of treating early users as collaborators rather than mere customers. The company has long refined vehicles through software updates and hardware changes informed by real-world use across its passenger cars.

Collecting structured opinions so soon after commercial service started shows the same mindset applied to a purpose-built autonomous taxi. The questions themselves reveal an openness to cabin changes even after the first vehicles reached public streets, which is no surprise.

Tesla has always hoped to cater a great experience to anyone in its vehicles, which is why so many fan-requested features have made it into its vehicles.

Replies already circulating online favor reclining seats, tray tables, wireless charging, improved audio, and extra room when seats fold back.

Those preferences point toward comfort upgrades that Tesla can implement in later production batches or through cabin revisions. Because the Cybercab is designed around software first principles, many requested amenities can arrive faster than in traditional automakers.

Tesla’s willingness to survey riders immediately after launch therefore makes near-term cabin and experience improvements likely as the team reviews responses and iterates toward a more refined robotaxi people will choose daily.

Tesla Cybertruck engineer reveals new changes in ‘constantly evolving’ pickup

Published

Tesla Cybertruck Lead Engineer Wes Morrill revealed the company has made several changes to the all-electric pickup, which he calls a “living thing, constantly evolving and improving.”

Cybertruck is manufactured at Tesla’s Gigafactory Texas just outside of Austin, and over the past few years, Tesla has continued to make small changes to the pickup to improve everything from cost, reliability, serviceablility, and manufacturability.

“The finish line isn’t getting to production. A product is a living thing, constantly evolving and improving,” Morrill added.

Some of those changes are yet to be revealed, but perhaps the most notable one was the change Tesla made to the aero shield that sits underneath the truck. In the past, it was aluminum, but now the Cybertruck is using a self-reinforcing polypropylene.

Morrill said that the polypropylene is “stretched into fibers and then laminated into the form,” and is much more durable, much lighter, and significantly cheaper than aluminum when it is manufactured this way.

It also enabled some improvements in the geometry of the Cybertruck, improving the manufacturing around the bolts and edges, in addition to minor form changes. These all benefitted the Cybertruck in more ways than one: specifically with durability and improved drag.

Typically, Teslas are not necessarily identified by model year because these changes are fluid and occur when the company sees fit to implement them. It is not like other automotive companies, which usually make sweeping manufacturing changes when building a new model year.

Instead, Teslas are recognized by their “generation” or “era.” For example, those with a newer Model Y might refer to their car as a “Juniper.” This is the same with Model 3, as many refer to the new body style as the “Highland.”

Tesla’s manufacturing changes are proof of the company’s constant need to improve its products and move things forward with its vehicles. There is no need to drag one’s feet and wait until next year if the product can be made better right now, and that’s precisely what Tesla did with the Cybertruck.

Tesla Cybercabs narrowly miss deadly Amazon cargo plane crash

An Amazon cargo plane crash near Miami’s airport stopped feet from dozens of Tesla Cybercabs.

An Amazon Prime Air Boeing 767 cargo jet overran the runway at Miami International Airport on Sunday afternoon, killing five people and injuring five more. The jet, operated by North Carolina based carrier 21 Air as Flight 7598, touched down around 2 p.m. after arriving from San Juan, Puerto Rico, then crossed the airport perimeter, plowed across NW 67th Avenue and struck multiple vehicles before catching fire, according to the Associated Press.

Photos and video from the scene show the aircraft’s nose stopped within meters of a fenced staging lot holding dozens of gold painted Tesla Cybercabs, the steering wheel free robotaxi Tesla began putting on public roads in Austin last week. Miami-Dade Fire Rescue has confirmed the plane struck “multiple vehicles” but has not said whether any Cybercabs were among them, and neither Tesla nor airport officials have addressed the fleet directly.

The Cybercabs had not yet entered commercial service in Miami. Tesla’s existing Robotaxi operation there runs on modified Model Y vehicles and has been unsupervised since Ashok Elluswamy confirmed the detail on X in July.


Elon Musk offered the briefest of reactions. Replying to a Zero Hedge post about the Cybercabs sitting so close to the wreckage, he wrote a single word: “Weird.” He has not commented further, and Tesla has not issued a statement.

The timing puts Tesla’s newest vehicle near an unrelated but highly visible tragedy just days after its Austin debut, a launch that had already drawn scrutiny from federal regulators. The National Highway Traffic Safety Administration opened an audit how Tesla certified the Cybercab as compliant with federal vehicle safety standards, a process Teslarati covered after the vehicle’s September 3 launch event. That inquiry concerns the car’s lack of a steering wheel and pedals, not the Miami crash.

Investigators from the FAA and NTSB are focused on the plane, not the parking lot beside it. Flight data reviewed by outlets including Simple Flying show the 767 touched down around 170 knots, well above the 135 to 140 knot range typical for the aircraft, though investigators have not determined a cause. Amazon said it is working with authorities and that its priority is the safety of everyone affected.

Whether any Cybercabs were damaged, and what Tesla plans for the fleet parked near one of the country’s busiest airports, remain open questions.
