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.

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?

Ukraine’s largest mobile operator, Kyivstar, has completed its first test of Starlink’s Direct to Cell satellite technology, enabling text messages to be sent directly from 4G smartphones without extra hardware. 

The trial was announced by the Ministry of Digital Transformation and Kyivstar’s parent company Veon in a press release.

First Eastern Europe field test

The Zhytomyr region hosted the pilot, where Deputy Prime Minister Mykhailo Fedorov and Kyivstar CEO Oleksandr Komarov exchanged texts and even made a brief video call via Starlink’s satellite link in northern Ukraine’s Zhytomyr region. 

Veon stated that the test marked Eastern Europe’s first field trial of the technology, which will allow Kyivstar’s 23 million subscribers to stay connected in areas without cellular coverage. The service will debut in fall 2025 with free text messaging during its testing phase.

“Our partnership with Starlink integrates terrestrial networks with satellite platforms, ensuring that nothing stands between our customers and connectivity – not power outages, deserts, mountains, floods, earthquakes, or even landmines,” Veon CEO Kaan Terzioglu stated.

Strategic push ahead of Nasdaq listing

Kyivstar signed its Direct to Cell agreement with Starlink in December 2024, about a year after a major cyberattack disrupted service and caused nearly $100 million in damages, as noted in a report from the Kyiv Independent. Starlink technology has been a pivotal part of Ukraine’s defense against Russia in the ongoing conflict.

“Despite all the challenges of wartime, we continue to develop innovative solutions, because reliable communication under any circumstances and in any location is one of our key priorities. Therefore, this Kyivstar project is an example of effective partnership between the state, business, and technology companies, which opens the way to the future of communication without borders,” Mykhailo Fedorov, First Deputy Prime Minister of Ukraine, said.

Tesla Model Y L spotted seemingly en route to showroom in China

It appears that Tesla has started shipping out some initial Model Y L units to select stores across China.

Tesla China definitely seems to be following an accelerated schedule in the well-speculated rollout of the Model Y L, the extended wheelbase, six-seat variant of the electric vehicle maker’s best-selling crossover.

Based on images that have been recently shared online, it appears that Tesla China has started shipping out some initial Model Y L units to select stores across the country.

Recent sighting

Last week, reports emerged suggesting that Giga Shanghai has started the production of the Model Y L. While the progress of the Model Y L’s rollout seems extremely quick, there have been notable signs that the electric car maker is indeed preparing for the rollout of the upcoming vehicle. The Model Y L, for example, was listed in the China Ministry of Industry and Information Technology’s (MIIT) latest batch of new energy vehicle models that are eligible for vehicle purchase tax exemptions.

Less than a week after these reports, Tesla watchers from China have shared photos of a mysterious vehicle being transported to a Tesla showroom in Jiangsu. The vehicle in the images was wrapped from bumper to bumper, though one could see that it is quite a bit longer than the other Model Y being transported in the same truck. Interestingly enough, the covered Model Y unit also seemed to be equipped with different front seats than standard Model Ys.

What to expect from the Model Y L

The MIIT’s listing for the Model Y have provided a pretty good teaser on what to expect from the extended wheelbase version of Tesla’s best-selling crossover. As per the MIIT’s list, the Model Y L will feature a 82.0-kWh lithium-ion battery from LG Energy Solution, which should give the vehicle a CLTC range of 751 km. The Model Y L is also expected to add roughly 178 mm (7 inches) to the overall length of the standard Model Y, with 152 mm (6 inches) being dedicated to stretching the wheelbase.

Initial images from the MIIT’s list also suggest that the Model Y L will feature a dedicated badge with an afterimage effect on the “Y.” The vehicle’s wheels also seemed to be equipped with a new set of 19” wheels that feature a star-esque pattern.

Elon Musk issues dire warning to Tesla (TSLA) shorts

This time around, Tesla shorts should probably heed his words.

Elon Musk has issued a dire warning to Tesla (NASDAQ:TSLA) short sellers. If they do not exit their position by the time Tesla attains autonomy, pain will follow. 

Musk has shared similar statements in the past, but this time around, Tesla shorts should probably heed his words.

Musk’s short warning

The Tesla CEO’s recent statement came as a response to Tesla retail shareholder and advocate Alexandra Merz, who shared a list of the electric vehicle maker’s short-sellers. These include MUFG Securities EMEA, Jane Street Group, Clean Energy Transition LLP, and Citadel Advisors, among others. As per the retail investor, some of Tesla’s short-sellers, such as Banque Pictet, have been decreasing their short position as of late.

In his reply, Elon Musk stated that Tesla shorts are on borrowed time. As per the CEO, TSLA shorts would be wise to exit their short position before autonomy is reached. If they do not, they will be wiped out. “If they don’t exit their short position before Tesla reaches autonomy at scale, they will be obliterated,” Musk wrote in his post.

Tesla’s autonomous program

Tesla short sellers typically disregard the progress that the company is making on its FSD program, which is currently being used in pilot ride-hailing programs in Austin and the Bay Area. While Tesla has taken longer than expected to attain autonomy, and while Musk himself admits to becoming the boy who cried FSD for years, autonomy does seem to be at hand this year. Tesla’s Unsupervised FSD is being used in Robotaxi services, and FSD V14 is poised to be released soon as well.

Elon Musk highlighted this in a response to X user Ian N, who noted that numerous automakers such as Audi, BMW, Fiat-Chrysler, Ford, GM, Honda, Mercedes-Benz, Volkswagen, and Toyota have all promised and failed in delivering autonomous systems for their vehicles. Thus, Tesla might be very late in the release of its autonomous features, but the company is by far the only automaker that is delivering on its promises today. Musk agreed with this notion, posting that “I might be late, but I always deliver in the end.”
