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.

Rolls-Royce makes shocking move on its EV future

When Rolls-Royce unveiled its first all-electric model, the Spectre, in 2022, former CEO Torsten Müller-Ötvös declared the brand would cease production of internal combustion engine vehicles by the end of the decade.

Rolls-Royce made a shocking move on its EV future after planning to go all-electric by the end of the decade. Now, the company is tempering its expectations for electric vehicles, and its CEO is aiming to lean on its legacy of high-powered combustion engines to lead it into the future.

In a significant reversal, Rolls-Royce Motor Cars has scrapped its ambitious plan to become an all-electric manufacturer by 2030. The luxury British marque announced the decision amid sustained customer demand for traditional combustion engines and shifting regulatory landscapes.

When Rolls-Royce unveiled its first all-electric model, the Spectre, in 2022, former CEO Torsten Müller-Ötvös declared the brand would cease production of internal combustion engine vehicles by the end of the decade.

The move aligned with the industry’s broader push toward electrification, promising silent, effortless power befitting the “Rolls-Royce of cars.”

However, new CEO Chris Brownridge, who assumed the role in late 2023, has reversed course. “We can respond to our client demand … we build what is ordered,” Brownridge stated.

The company will continue offering its iconic V12 engines, which remain a cornerstone of its heritage and appeal to discerning buyers who appreciate the distinctive sound and character. He noted the original pledge was “right at the time,” but “the legislation has changed.”

While not abandoning electric vehicles entirely, the Spectre remains in production, with an electric Cullinan option forthcoming; the decision marks the end of a strict all-EV timeline. Relaxed emissions regulations and slowing EV demand, evidenced by a 47 percent drop in Spectre sales to 1,002 units in 2025, forced the reconsideration.

It was a sign that perhaps Rolls-Royce owners were not inclined to believe that the company’s all-EV future was the right move.

Rolls Royce customers want more EVs, says company CEO

Rolls-Royce joins a growing roster of automakers reevaluating aggressive electrification targets.

Fellow luxury brand Bentley has pushed its full electrification from 2030 to 2035, while continuing to offer hybrids and ICE models. Mercedes-Benz walked back its 2030 all-EV goal, now aiming for about 50% electrified sales while keeping combustion engines into the 2030s. Porsche has abandoned its 80% EV sales target by 2030, delaying models and extending hybrids.

Mainstream giants are following suit. Honda canceled its U.S. EV plans, including the 0-Series and Acura RSX, facing a $15.7 billion hit as it doubles down on hybrids. Ford and General Motors have incurred tens of billions in writedowns, canceling models and pivoting to hybrids amid an industry total exceeding $70 billion in charges.

This trend reflects a pragmatic shift driven by infrastructure gaps, consumer preferences, and policy changes. In the ultra-luxury segment, where emotional connection reigns, automakers are prioritizing flexibility over rigid deadlines, ensuring brands like Rolls-Royce evolve without alienating their core clientele.

Tesla CEO Elon Musk is outlining expectations for the AI6 self-driving chip, which is still two generations away. Despite this, it is already in the plans of the company and its serial entrepreneur CEO, who has high expectations for it.

Musk provided fresh details on the company’s aggressive AI hardware roadmap, spotlighting the upcoming AI6 chip designed to supercharge Tesla’s self-driving tech, humanoid robots, and data center operations.

In a post on X dated March 19, Musk stated, “With some luck and acceleration using AI, we might be able to tape out AI6 in December.”

This optimistic timeline for tape-out—the stage where chip design is finalized before manufacturing—signals Tesla’s push to rapidly advance its silicon capabilities.

The announcement builds on progress with the predecessor AI5. Earlier in January, Musk announced that the AI5 design was “in good shape” and “almost done,” describing it as an “existential” project for the company that demanded his personal attention on weekends.

He characterized AI5 as roughly equivalent to Nvidia’s Hopper class performance in a single system-on-chip (SoC) and Blackwell-level as a dual configuration, but at significantly lower cost and power usage.

Elon Musk is setting high expectations for Tesla AI5 and AI6 chips

Musk highlighted that AI5 “will punch far above its weight” thanks to Tesla’s co-designed AI software and hardware stack, making maximal use of every circuit. While capable of data center training tasks, it is primarily optimized for edge computing in Optimus robots and Robotaxi vehicles.

For AI6, Musk envisions substantial gains. “In the same half reticle and same process node, we think a single AI6 chip has the potential to match a dual SoC AI5,” he explained.

The company is targeting ambitious nine-month development cycles for future chips, allowing rapid iteration to AI7, AI8, and beyond. AI5/AI6 engineering remains Musk’s top time allocation at Tesla, with the CEO calling AI5 “good” and AI6 “great.”

Samsung is expected to manufacture the AI6 chips, following deals worth billions, while AI5 will leverage TSMC and Samsung production. These chips will form the backbone of Tesla’s Full Self-Driving system, enabling safer and more capable autonomy, alongside powering dexterous movements in Optimus bots and efficient inference in expanding data centers.

Tesla to discuss expansion of Samsung AI6 production plans: report

Musk has also restarted work on the Dojo 3 supercomputer project now that AI5 is progressing. Long-term plans include in-house manufacturing via the Terafab facility.

By accelerating chip development with AI tools, Tesla aims to reduce dependence on third-party GPUs and deliver high-performance, energy-efficient solutions tailored to its ecosystem. Success with AI6 could mark a major milestone in Tesla’s journey toward full autonomy and robotics leadership, though timelines remain subject to manufacturing realities.

SpaceX is quietly becoming the U.S. Military’s only reliable rocket

Space Force drops ULA for SpaceX on GPS launch after Vulcan rocket anomaly investigation halts flights.

Published

By

The U.S. Space Force announced today it is switching an upcoming GPS III satellite launch from United Launch Alliance’s Vulcan rocket to a SpaceX Falcon 9, a move that is as much a reflection of Vulcan’s mounting problems as it is a validation of SpaceX’s growing dominance in national security space launch. The GPS III Space Vehicle 09, originally contracted to fly on Vulcan this month, will now target a late April liftoff on Falcon 9, marking the fourth consecutive GPS III satellite the Space Force has moved to SpaceX after contracts were originally awarded to ULA.

The immediate trigger is a solid rocket motor anomaly that occurred on February 12 during Vulcan’s USSF-87 mission. Although the payloads reached orbit and ULA declared the mission successful, the company characterized the malfunction as a “significant performance anomaly” and has since paused all military launches on Vulcan pending a root cause investigation.

“With this change, we are answering the call for rapid delivery of advanced GPS capability while the Vulcan anomaly investigation continues,” said Systems Delta 81 Commander Col. Ryan Hiserote. “We are once again demonstrating our team’s flexibility and are fully committed to leverage all options available for responsive and reliable launch for the Nation.”

The broader reality is that SpaceX’s reliability record and launch cadence have made it the path of least resistance for the Pentagon, and bodes well with Elon Musk’s plans to IPO SpaceX sometime this year. Its Falcon 9 is the most flight-proven rocket in history, and the Space Force’s Rapid Response Trailblazer program was specifically designed to enable exactly this kind of provider swap for GPS missions, and effectively building SpaceX’s flexibility into the national security launch architecture by design.

SpaceX IPO is coming, CEO Elon Musk confirms

For ULA, the stakes are existential. The company entered 2026 with aspirations of finally turning a corner after years of Vulcan delays, with interim CEO John Elbon pointing to a backlog of over 80 missions as reason for optimism. Meanwhile, SpaceX’s contracts with the Space Force have given it a formal pathway to take on even more national security launches going forward.

The significance of today’s announcement extends beyond one satellite swap. It reinforces that America’s most critical space infrastructure, including GPS, missile warning, and beyond, is increasingly dependent on a single commercial provider.
