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?

Elon Musk reveals Tesla’s next Robotaxi expansion in more ways than one

Tesla Robotaxi is growing in more ways than one. Tesla wants to expand and hopes to reach half the U.S. population by the end of the year.

Tesla CEO Elon Musk revealed the company’s plans for its next expansion of the Robotaxi in terms of both the geofence in Austin and the platform overall, as it looks to move to new areas outside of Texas.

Tesla launched the Robotaxi platform last month on June 22, and has since expanded both the pool of users and the area that the driverless Model Y vehicles can travel within.

The first expansion of the geofence caught the attention of nearly everyone and became a huge headline as Tesla picked a very interesting shape for the new geofence, resembling male reproductive parts.

The next expansion will likely absolve this shape. Musk revealed last night that the new geofence will be “well in excess of what competitors are doing,” and it could happen “hopefully in a week or two.”

Musk’s full quote regarding the expansion of the geofence and the timing was:

“As some may have noted, we have already expanded our service area in Austin. It’s bigger and longer, and it’s going to get even bigger and longer. We are expecting to greatly increase the service area to well in excess of what competitors are doing, hopefully in a week or two.”

The expansion will not stop there, either. As Tesla has operated the Robotaxi platform in Austin for the past month, it has been working with regulators in other areas, like California, Arizona, Nevada, and Florida, to get the driverless ride-hailing system activated in more U.S. states.

Tesla confirmed that they are in talks with each of these states regarding the potential expansion of Robotaxi.

Musk added:

“As we get the approvals and prove out safety, we will be launching the autonomous ride-hailing across most of the country. I think we will probably have autonomous ride-hailing in probably half the population of the US by the end of the year.”

We know that Tesla and Musk have been prone to aggressive and sometimes outlandish timelines regarding self-driving technology specifically. Regulatory approvals could happen by the end of the year in several areas, and working on these large metros is the best way to reach half of the U.S. population.

Tesla said its expansion of the geofence in Austin is conservative and controlled due to its obsession with safety, even admitting at one point during the Earnings Call that they are being “paranoid.” Expanding the geofence is necessary, but Tesla realizes any significant mistake by Robotaxi could take it back to square one.

Tesla warns customers of incentive strategy on EVs as tax credit nears end

If you’re thinking of buying a Tesla, the time to order is now, the company claimed.

Tesla has warned customers about its incentive strategy for qualifying electric vehicles, as the days of both the $7,500 EV tax credit for new EVs and the $4,000 credit for used EVs are coming to a close.

Both tax credits, which impact some of the vehicles in the Tesla lineup, are set to be eliminated at the end of Q3. The phase out of these consumer credits was always in the plans of the Trump Administration, but now we’re in the final quarter of their existence.

As a result, EV companies are scrambling to see how they can reduce costs or make their vehicles more affordable for customers. The $7,500 will price many consumers out of many EVs on the market, and Tesla is not immune to that.

However, Tesla has made a significant push into Q3 deliveries, rolling out numerous incentives to customers, including 0% APR on select purchases, lease deals, free upgrades on certain inventory units, and more.

The extensive list of incentives on Tesla vehicles in the quarter will not get any longer, either. During last night’s Tesla Earnings Call for the second quarter of 2025, company executives stated that their intention for these incentives was to encourage customers to place orders early in the quarter.

Tesla will only be able to apply the $7,500 credit with deliveries that occur before the end of September. Even if an order is placed before then, delivery must be completed by September 31 to receive the tax credit.

CFO Vaibhav Taneja confirmed that the incentives for the quarter are already out and encouraged customers to place an order sooner rather than later:

“Given the abrupt change, we have a limited supply of vehicles in the US this quarter. As we are already within lead times to order parts for cars, we have rolled out all our planned incentives already and will start pairing them back as we start to sell. If you are in the US and looking to buy a car, let’s roll now as we may not be able to guarantee delivery for orders placed in the later part of August and beyond.”

The loss of the incentives will impact every EV maker in the United States. Tesla has a plan moving forward, and it said last night that its affordable models would be rolled out in Q4, as introducing these cars any earlier could have detrimental effects on Model 3 and Model Y sales.

Tesla Model Y awarded Top Safety Pick+ from IIHS

The new Model Y continues to impress with this new award.

Published

The 2025 Tesla Model Y was one of two midsize luxury SUVs to receive the Top Safety Pick+ award from the Insurance Institute for Highway Safety (IIHS).

To qualify for the IIHS’s Top Safety Pick+ or even the lower-tier Top Safety Pick label, vehicles need good ratings in the small overlap front and side crash tests, an acceptable or good rating in the pedestrian front crash prevention evaluation, and acceptable or good ratings for headlights across all trim levels.

The difference between the two labels is that an “Acceptable” rating in the moderate overlap front test will get a car the Top Safety Pick rating, but a “Good” rating in this category will win the elusive Top Safety Pick+ category.

The 2025 Model Y, codenamed “Juniper” internally by Tesla, was released in the United States earlier this year and received the top rating across each of the categories, automatically qualifying it for the Top Safety Pick+ label:

Other vehicles in Tesla’s lineup have extraordinary marks in crash testing according to other agencies, like the National Highway Traffic Safety Administration (NHTSA), but there are reasons those cars are not on the IIHS lists.

In 2024, we reported that the IIHS had evaluated some Tesla vehicles for the necessary tests to achieve these marks. Joe Young of the agency told us that the Model 3, for example, was not featured on either the Top Safety Pick or Top Safety Pick+ lists because the vehicle had several missing tests.

Here’s why the Tesla Model 3 wasn’t an IIHS Top Safety Pick+, and why it could be soon

This is not to say those other Tesla vehicles would not perform well. The Cybertruck performed better than any pickup has ever in NHTSA crash testing assessments.

The Model Y is Tesla’s most popular vehicle and was the best-selling car in the world over the past two years. Tesla’s intense focus on safety continues to show that this priority goes into every decision the company makes regarding design and engineering. This focus has continued to pay dividends as some real-world crashes save the lives of those inside the cars.
