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.

IM Motors co-CEO apologizes to Tesla China over FUD comments

Liu said later investigations showed the accident was not caused by a brake failure on the Tesla’s part, contrary to his initial comments.

Liu Tao, co-CEO of IM Motors, has publicly apologized to Tesla China for comments he made in 2022 suggesting a Tesla vehicle was defective following a fatal traffic accident in Chaozhou, China. 

Liu said later investigations showed the accident was not caused by a brake failure on the Tesla’s part, contrary to his initial comments.

IM Motors co-CEO issues apology

Liu Tao posted a statement addressing remarks he made following a serious traffic accident in Chaozhou, Guangdong province, in November 2022, as noted in a Sina News report. Liu stated that based on limited public information at the time, he published a Weibo post suggesting a safety issue with the Tesla involved in the crash. The executive clarified that his initial comments were incorrect.

“On November 17, 2022, based on limited publicly available information, I posted a Weibo post regarding a major traffic accident that occurred in Chaozhou, suggesting that the Tesla product involved in the accident posed a safety hazard. Four hours later, I deleted the post. In May 2023, according to the traffic police’s accident liability determination and relevant forensic opinions, the Chaozhou accident was not caused by Tesla brake failure.

“The aforementioned findings and opinions regarding the investigation conclusions of the Chaozhou accident corrected the erroneous statements I made in my previous Weibo post, and I hereby clarify and correct them. I apologize for the negative impact my inappropriate remarks made before the facts were ascertained, which caused Tesla,” Liu said. 

Investigation and court findings

The Chaozhou accident occurred in Raoping County in November 2022 and resulted in two deaths and three injuries. Video footage circulated online at the time showed a Tesla vehicle accelerating at high speed and colliding with multiple motorcycles and bicycles. Reports indicated the vehicle reached a speed of 198 kilometers per hour.

The incident drew widespread attention as the parties involved provided conflicting accounts and investigation details were released gradually. Media reports in early 2023 said investigation results had been completed, though the vehicle owner requested a re-investigation, delaying the issuance of a final liability determination.

The case resurfaced later in 2023 following a defamation lawsuit filed by Tesla China against a media outlet. According to a court judgment cited by Shanghai Securities News, forensic analysis determined that the fatal accident was unrelated to any malfunction on the Tesla’s braking or steering systems. The court also ruled that the media outlet must publish an apology, address the negative impact on Tesla China’s reputation, and pay a penalty of 30,000 yuan.

SpaceX is reportedly exploring new products tied to Starlink, including a potential Starlink-branded phone. 

The update was reportedly shared to Reuters by people familiar with the matter. 

A possible Starlink Phone

As per Reuters’ sources, SpaceX has reportedly discussed building a mobile device designed to connect directly to the Starlink satellite constellation. Details about the potential device and its possible release are still unclear, however.

SpaceX has dabbled with mobile solutions in the past. The company has partnered with T-Mobile to provide Starlink connectivity to existing smartphones. And last year, SpaceX initiated a $19.6 billion purchase of satellite spectrum from EchoStar.

Elon Musk did acknowledge the idea of a potential mobile device recently on X, writing that a Starlink phone is “not out of the question at some point.” Unlike conventional smartphones, however, Musk described a device that is “optimized purely for running max performance/watt neural nets.” 

Starlink and SpaceX’s revenue

Starlink has become SpaceX’s dominant commercial business. Reuters’ sources claimed that the private space company generated roughly $15–$16 billion in revenue last year, with about $8 billion in profit. Starlink is estimated to have accounted for 50% to 80% of SpaceX’s total revenue last year.

SpaceX now operates more than 9,500 Starlink satellites and serves over 9 million users worldwide. About 650 satellites are already dedicated to SpaceX’s direct-to-device initiative, which aims to eventually provide full cellular coverage globally.

Future expansion of Starlink’s mobile capabilities depends heavily on Starship, which is designed to launch larger batches of upgraded Starlink satellites. Musk has stated that each Starship launch carrying Starlink satellites could increase network capacity by “more than 20 times.”

The Federal Communications Commission (FCC) has accepted SpaceX’s filing for a new non-geostationary orbit (NGSO) satellite system of up to one million spacecraft and has opened the proposal for public comment. 

The move formally places SpaceX’s “Orbital Data Center” concept into the FCC’s review process, marking the first regulatory step for the ambitious space-based computing network.

FCC opens SpaceX’s proposal for comment

In a public notice, the FCC’s Space Bureau stated that it is accepting SpaceX’s application to deploy a new non-geostationary satellite system known as the “SpaceX Orbital Data Center system.” As per the filing, the system would consist of “up to one million satellites” operating at altitudes between 500 and 2,000 kilometers, using optical inter-satellite links for data transmission.

The FCC notice described the proposal as a long-term effort. SpaceX wrote that the system would represent the “first step towards becoming a Kardashev II-level civilization – one that can harness the Sun’s full power.” The satellites would rely heavily on high-bandwidth optical links and conduct telemetry, tracking, and command operations, with traffic routed through space-based laser networks before being sent to authorized ground stations.

FCC Chairman Brendan Carr highlighted the filing in a post on X, noting that the Commission is now seeking public comment on SpaceX’s proposal. Interested parties have until early March to submit comments.

What SpaceX is proposing to build

As per the FCC’s release, SpaceX’s orbital data center system would operate alongside its existing and planned Starlink constellations. The FCC notice noted that the proposed satellites may connect not only with others in the new system, but also with satellites in SpaceX’s first- and second-generation Starlink networks.

The filing also outlined several waiver requests, including exemptions from certain NGSO milestone and surety bond requirements, as well as flexibility in how orbital planes and communication beams are disclosed, as noted in a Benzinga report. SpaceX noted that these waivers are necessary to support the scale and architecture of the proposed system.

As noted in coverage of the filing, the proposal does not represent an immediate deployment plan, but rather a framework for future space-based computing infrastructure. SpaceX has discussed the idea of moving energy-intensive computing, such as AI workloads, into orbit, where continuous solar power and large physical scale could reduce constraints faced on Earth.
