SolarCity poised for rapid growth as residential solar installations soar
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 takes owner on a 20,000+ mile joy ride
Tesla owner David Moss just pushed his intervention free FSD streak past 20,000 miles total.
Tesla Model 3 owner David Moss has spent the better part of eight months turning his vehicle into a rolling stress test for Full Self-Driving, and this week he pushed his single, continuous FSD streak past 20,000 miles without a human intervening.
Moss, a Tacoma, Washington resident who sells LiDAR scanning equipment for a living, first drew wide attention in December 2025 when he logged 10,000 consecutive miles on FSD v14.2. Days later he drove from the Tesla Diner in Los Angeles to Myrtle Beach, South Carolina, covering 2,732 miles in two days and 20 hours with zero disengagements, the first verified coast to coast autonomous drive in Tesla’s history. Tesla even featured the trip as an official customer story in March. That original streak eventually reached 12,961 miles across 30 states before ending in rural Wisconsin in January, when snow and single digit temperatures forced Moss to take over.
Tesla FSD successfully completes full coast-to-coast drive with zero interventions
He started over, and this run has gone further. In late May, Moss drove 3,760 miles across Canada with two companions, from Horseshoe Bay in Vancouver to a Tesla showroom in Halifax, again without a single intervention, a trip Tesla AI software VP Ashok Elluswamy publicly congratulated him for on X. In June, he pushed the same unbroken streak south, aiming to link the Canadian border to the Mexican border, and crossed 10,000 miles on Tesla’s newly added in car streak counter along the way, the first driver to do so since Tesla began showing confetti animations for the feature.
20,000 Mile Tesla FSD Screen Streak!
Special thank you to @DevinOlsenn, @scotsrule08, & @OwenSparks for helping co drive during all these fun adventures these last couple of months
Also thank you to @wholemars for always tracking me along the journey verifying it all with his… pic.twitter.com/CZ2yO6Ev0X

It’s worth noting that every mile is logged through the FSD Database, a community run tracker built by Tesla influencer Omar Qazi, well known as @WholeMars on X, that pulls telemetry straight from the car and records disengagements down to a tenth of a mile. That verification is what separates Moss’s numbers from casual claims on social media.
The streak itself is a fairly recent addition to Tesla’s software. FSD v14.2 introduced a Self Driving Stats panel tracking the ratio of autonomous to manual miles, and v14.3.4 added the live streak counter in June, which resets the moment a driver brakes, wrenches the wheel or cancels navigation. Reaching 20,000 miles on that counter means a single Tesla drove itself through countless highways, city grids, construction zones and Supercharger stalls without a single reset.
Moss has said the goal was never to set a record for its own sake, but to show, mile by verified mile, what the software can already do.
Elon Musk told The Economist that artificial intelligence will likely surpass the combined intelligence of every human on Earth within about five years, and that humans may not remain in charge once that happens. In a wide-ranging interview with editor-in-chief Zanny Minton Beddoes, recorded at Giga Texas for the outlet’s Insider series, Musk compared the widening gap between AI and human intelligence to the gap between humans and chimpanzees.
“It’s hard to imagine that the chimpanzee would be in charge,” he said, addressing what happens to human authority once AI moves far beyond us.
Elon Musk reiterates his most optimistic prediction yet with “UHI” forecast
Musk’s timeline stretches out from there. Five years for AI to out-think humanity combined, ten years before humans lose meaningful control, and by 2036, he says, money itself may stop mattering.
Musk notes that if robots and AI produce more goods and services than people could ever consume, currency loses its purpose. He told Beddoes that governments could respond with direct payments, what he called “universal high income,” a term he first used in an X post last August describing a future where “everyone will have the best medical care, food, home, transport and everything else.”
There will be universal high income (not merely basic income).
Everyone will have the best medical care, food, home, transport and everything else.
Sustainable abundance.

He also floated a more surprising prediction that deflation, and not inflation, would become the bigger economic problem, since expanding the supply of goods and services faster than the money supply grows would push prices down rather than up.
None of this is new territory for Musk, who has spent years describing an “age of abundance” built on Optimus and autonomous vehicles. What’s notable is the timing. The interview landed the same week Tesla shares dropped roughly 19 percent following a second quarter earnings report that beat on revenue but missed badly on profit, and as SpaceX stock continues to slide from its post-IPO peak.
Musk’s own net worth has fallen close to $700 billion since mid-June, according to the Bloomberg Billionaires Index, even as he describes a future where personal wealth stops being the point.
Musk did not dodge the risk side of the equation either. He put the odds of AI contributing to human extinction somewhere in the 10 to 20 percent range, then arrived at what he called his “philosophical conclusion” since the technology cannot realistically be stopped and the arguably better response is to keep building it and hope the outcome leans toward abundance rather than catastrophe. “I’ve gone from exhilaration to terror regarding AI,” he told Beddoes, “even intraday.”
Tesla is adding a new “Traction Control Modes” feature to its cars for better handling in any conditions. These features will roll out to the Model 3 and Model Y, the two vehicles in Tesla’s lineup that typically do not have drive modes for various conditions.
Tesla did include this in the Model S and Model X, as well as the Cybertruck.
The new feature will roll out with the 2026 Summer Update, which Tesla announced last week and subsequently started rolling out to some owners today. The Summer Update is the latest iteration of the usual four seasonal releases the company rolls out throughout the year. These releases typically feature some owner-requested features, as well as improvements to things like the Full Self-Driving suite.
Tesla reveals 2026 Summer Update with crazy fixes to Nav and more
This release is no different. Among the changes are improvements to Navigation, new customization options with wraps and how they can be shared and stored, more functionality with the Tesla smartphone app, and new gamification with self-driving.
However, Tesla announced today that it was adding another feature to the Summer Update. Traction Control Modes will now be available with the release
Tesla describes them:
-
“Choose from three updated Traction Control Modes: Auto for normal driving conditions, Slippery Surface for icy or wet roads, Stuck Assist when stuck in snow, mud, or sand. The mode resets to Auto at the start of each drive. To select, go to Controls > Dynamics > Traction Control Mode.”
Tesla’s 2026 Summer Update also includes new Traction Control Modes

The use of these modes will help improve a Tesla’s overall performance in less-than-ideal conditions. Typically, these traction control modes monitor wheel speed through sensors and track engine power to adjust responsiveness in various conditions.
These drive modes are not an ultimate solution to all driving conditions; just because there is a “Stuck Assist,” doesn’t mean your Tesla will dig itself out of a foot-and-a-half trench during a blizzard. It is important to remember that some of these scenarios also require some assistance from the driver. For example, driving in sand requires tires to be aired down significantly to increase traction and control.
However, this will be a welcome addition for those who use the Full Self-Driving suite and might not be convinced of its performance in adverse conditions. Some of us prefer to be in control in rain, snow, or ice, which is totally understandable. However, adjusting the Traction Control Mode while utilizing FSD in snow, rain, or ice could increase confidence and overall experience.

Tesla’s Summer Update is already rolling out to some owners, so it should be making its way to most of the fleet over the next several weeks. The Spring Update rolled out at a very conservative pace, so if you don’t have it by the end of August, don’t be too upset. It might just be Tesla’s method.
