SolarCity poised for rapid growth as residential solar installations soar

Published

on

The recent merger of Tesla and SolarCity introduces a new era in residential solar energy generation. With the demand for solar energy in the U.S. rising each year, benefits to both our environment and the nation’s economy increase. The trend toward residential solar installations does require efficient planning and execution of public policies. It also calls for analysis of the status of residential solar in order to move toward an enhanced solar integration across the U.S.

What does residential solar look like today in the U.S.?

Residential solar today is primarily a coastal phenomenon, although more than half of the states have enough residential solar to power at least a few thousand homes. Yet, in the third quarter of 2016, the U.S. surpassed all previous quarterly solar photovoltaic (PV) installation records: 4,143 megawatts (MW), or a rate of one megawatt (MW) every 32 minutes. That pace is even faster today, as the fourth quarter will surpass this past quarter’s historic total, according to the Solar Energies Industry Association (SEIA).

“The solar market now enjoys an economically-winning hand that pays off both financially and environmentally, and American taxpayers have noticed,” Tom Kimbis, SEIA’s interim president, said of the recent rise in residential solar. “With a 90 percent favorability rating and 209,000 plus jobs, the U.S. solar industry has proven that when you combine smart policies with smart 21st century technology, consumers and businesses both benefit.”

Here are the top five U.S. states with residential solar rooftops in September, 2016:

  • California: 3,258 MW
  • Arizona: 539 MW
  • New York: 444 MW
  • New Jersey: 386 MW
  • Massachusetts: 361 MW

These levels are considered ample to power a significant number of homes in their regions.

What’s the potential for other states to increase residential solar in the near future?

In order to power more than a few thousand homes and to become a major energy source across America, solar saturation must become deeper across existing states and more widespread among states that currently provide limited residential solar. Rooftops provide a large expanse of untapped area for solar energy generation, according to the National Renewable Energy Laboratory (NREL). What’s needed to reduce costs and losses often associated with transmission and distribution of electricity? Onsite distributed generation, such as that which is available from SolarCity and others. Yet, to create a paradigm in which onsite distributed generation can become a reality, different and sometimes dissonant potentials must be addressed.

Technical potential considers multiple factors in a given region, such as resource availability and quality, technical system performance, and the physical availability of a suitable area for development. In other words, it measures how much of the total resource can actually be captured. It is often the only area of focus when residential solar is discussed.

However, in order for solar to reduce pollution, help homeowners to lower utility bills and gain more energy independence, technical aspects of the larger solar equation must work in sync with resource, economic and market potential.

  • Resource potential is the entire amount of energy in a particular form for the region;
  • Economic potential is possible generation quantity that results as a positive return on the
    investment of constructing the systems; and,
  • Market potential estimates the quantity of energy expected to be generated from the deployment of a technology into the market. It considers factors such as policies, competition with other technologies, and rate of adoption.

A study from the NREL indicates that, taking into account these four types of potential, there are broad regional trends in both the suitability and electric-generation possibilities of rooftops. Although only 26% of the total rooftop area on small buildings is suitable for PV deployment, the sheer number of buildings in this class gives small buildings the greatest technical potential.

What factors contribute to successful onsite distributed solar generation?

Small building rooftops could accommodate 731 GW of PV capacity and generate 926 TWh of PV energy annually, according to NREL, which represents approximately 65% of the total technical potential of rooftop PV. Think about how much energy could be generated by rooftop solar panels in each state if they were installed on all suitable roofs. Of course, the amount of suitable roof area, which takes into account factors such as shading, roof tilt, roof position, and roof size, must be included in any potential residential solar project planning.

The folks at SolarCity truly believe that, in every state, home rooftop solar could be a major energy resource. With research data backing their conclusions, they feel that U.S. total home solar capacity could increase 100 times over, and each state could meet 10-45% of its electricity needs from residential solar alone.

Add in roofs of medium and large buildings, and the solar integration number rises to 40 percent of all the electric demand in the continental U.S. By comparison, all rooftop solar today combined provides less than 0.5 percent of the nation’s electricity.

The potential for home rooftop solar to become a major energy source is enormous — in every state. And SolarCity argues that, the sooner that homes across the country become a part of that future, the more years they’ll have to enjoy its benefits.

Tesla FSD fleet is nearing 7 billion total miles, including 2.5 billion city miles

As can be seen on Tesla’s official FSD webpage, vehicles equipped with the system have now navigated over 6.99 billion miles.

Published

on

Tesla’s Full Self-Driving (Supervised) fleet is closing in on almost 7 billion total miles driven, as per data posted by the company on its official FSD webpage. 

These figures hint at the massive scale of data fueling Tesla’s rapid FSD improvements, which have been quite notable as of late.

FSD mileage milestones

As can be seen on Tesla’s official FSD webpage, vehicles equipped with the system have now navigated over 6.99 billion miles. Tesla owner and avid FSD tester Whole Mars Catalog also shared a screenshot indicating that from the nearly 7 billion miles traveled by the FSD fleet, more than 2.5 billion miles were driven inside cities. 

City miles are particularly valuable for complex urban scenarios like unprotected turns, pedestrian interactions, and traffic lights. This is also the difference-maker for FSD, as only complex solutions, such as Waymo’s self-driving taxis, operate similarly on inner-city streets. And even then, incidents such as the San Francisco blackouts have proven challenging for sensor-rich vehicles like Waymos. 

Tesla’s data edge

Tesla has a number of advantages in the autonomous vehicle sector, one of which is the size of its fleet and the number of vehicles training FSD on real-world roads. Tesla’s nearly 7 billion FSD miles then allow the company to roll out updates that make its vehicles behave like they are being driven by experienced drivers, even if they are operating on their own.

So notable are Tesla’s improvements to FSD that NVIDIA Director of Robotics Jim Fan, after experiencing FSD v14, noted that the system is the first AI that passes what he described as a “Physical Turing Test.” 

“Despite knowing exactly how robot learning works, I still find it magical watching the steering wheel turn by itself. First it feels surreal, next it becomes routine. Then, like the smartphone, taking it away actively hurts. This is how humanity gets rewired and glued to god-like technologies,” Fan wrote in a post on X.

Tesla has launched Europe’s first public shuttle service using Full Self-Driving (Supervised) in the rural Eifelkreis Bitburg-Prüm region of Germany, demonstrating how the technology can restore independence and mobility for people who struggle with limited transport options. 

Local officials tested the system on narrow country roads and were impressed by FSD’s smooth, human-like driving, with some calling the service a game-changer for everyday life in areas that are far from urban centers.

Officials see real impact on rural residents

Arzfeld Mayor Johannes Kuhl and District Administrator Andreas Kruppert personally tested the Tesla shuttle service. This allowed them to see just how well FSD navigated winding lanes and rural roads confidently. Kruppert said, “Autonomous driving sounds like science fiction to many, but we simply see here that it works totally well in rural regions too.” Kuhl, for his part, also noted that FSD “feels like a very experienced driver.”

The pilot complements the area’s “Citizen Bus” program, which provides on-demand rides for elderly residents who can no longer drive themselves. Tesla Europe shared a video of a demonstration of the service, highlighting how FSD gives people their freedom back, even in places where public transport is not as prevalent.

What the Ministry for Economic Affairs and Transport says

Rhineland-Palatinate’s Minister Daniela Schmitt supported the project, praising the collaboration that made this “first of its kind in Europe” possible. As per the ministry, the rural rollout for the service shows FSD’s potential beyond major cities, and it delivers tangible benefits like grocery runs, doctor visits, and social connections for isolated residents.
