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.

Michael Dell points out practical advantage of Elon Musk’s proposed pay package
As pointed out by the Dell Technologies CEO, Musk will only be rewarded if he delivers extraordinary value to shareholders
Michael Dell has weighed in on Elon Musk’s controversial 2025 CEO Performance Award, offering a grounded perspective amidst the noise surrounding the pay package today.
As pointed out by the Dell Technologies CEO, Musk will only be rewarded if he delivers extraordinary value to shareholders. Musk would quite literally receive no compensation if he fails to achieve his targets.
Dell emphasizes results over rhetoric
Dell shared his thoughts about Musk’s 2025 CEO Performance Award in a post on X.“Vote FOR Elon Musk. The award is only achieved IF he hits exceptionally ambitious market-cap and operational milestones—if he falls short, he gets nothing,” Dell wrote in his post.
“If he succeeds, shareholders will win big through unprecedented value creation, and he will earn added voting rights to continue driving Tesla’s long-term vision.”
Musk replied with a short “Thanks Michael,” acknowledging Dell’s support. Dell’s framing cuts through the debate surrounding Musk’s compensation, as he simply focused on the incentive structure’s risk-reward balance.
Musk’s ambitious pay package
Elon Musk’s 2025 CEO Performance Award requires Tesla’s market capitalization to rise from roughly $1.1 trillion today to $8.5 trillion within a decade. This would make Tesla more valuable than any company in history.
Apart from this, Tesla’s operating profit must also grow from $17 billion to $400 billion annually. Musk must also lead the company to several product-related milestones, such as 20 million cumulative vehicle deliveries, 10 million Full Self-Driving subscriptions, 1 million Tesla Bots, and 1 million operating Robotaxis.
So far, proxy advisors Glass Lewis and ISS have urged shareholders to vote against the plan. Some prominent investors, including ARK Invest CEO Cathie Wood, however, have voiced strong support for the plan. Wood called Musk “the most productive human being on earth,” arguing that his vision and ability to attract talent are central to Tesla’s success.

Starlink V3 satellites could enable SpaceX’s orbital computing plans: Musk
Musk’s remarks come as companies explore how orbital infrastructure could solve the Earth-bound energy and cooling challenges that come with hyperscale AI computing.
As artificial intelligence fuels surging demand for computing power, Elon Musk has hinted that SpaceX may use its Starlink V3 satellites to develop space-based data centers.
Musk’s remarks come as companies explore how orbital infrastructure could solve the Earth-bound energy and cooling challenges that come with hyperscale AI computing.
SpaceX could lead the race to orbit-based computing
After Ars Technica published a report on autonomous space construction, Musk replied on X: “Simply scaling up Starlink V3 satellites, which have high speed laser links would work. SpaceX will be doing this.”
SpaceX’s Starlink V3 platform is capable of up to 1 terabit per second (Tbps) throughput, so it could potentially form the foundation for orbital computing clusters powered by solar energy.
Proponents have noted that such data centers could eliminate the massive land, water, and power footprints of traditional facilities on Earth. Critics, however, have question the economics and complexity of maintaining large-scale data systems in orbit.
Elon Musk, for his part, recently reiterated on X that this particular idea is a very big deal.
SpaceX’s track record is substantial
Despite the reservations for such a radical idea, SpaceX’s track record is pretty much bulletproof at this point. The company’s Starlink network, once deemed as unrealistic by critics, now delivers broadband to millions worldwide while turning a profit. Its Falcon 9 rockets, which are capable of landing on land or on a drone in the middle of the ocean, are also among the world’s most reliable.
With this track record in mind, it would seem that Elon Musk’s idea of using Starlink satellites as the building blocks for a space-based data center might not be too farfetched at all.
Interest in space-based data storage and processing has intensified in recent months, Ars noted. Former Google CEO Eric Schmidt reportedly acquired Relativity Space with an eye on orbital data infrastructure, while Jeff Bezos recently predicted gigawatt-scale data centers will operate in space within two decades.

Tesla Model Y L gains V2L capabilities with software update
The 2025.32.300 update, which is rolling out to Model Y L vehicles in China, introduces several notable additions.
Tesla has quietly added Vehicle-to-Load (V2L) functionality to the Model Y L through its latest over-the-air update in China, giving owners the ability to power external devices directly from their EVs.
The addition of the feature was highlighted by Tesla in its release notes for China’s 2025.32.300 update.
Model Y L gains V2L and other convenience upgrades
The 2025.32.300 update, which is rolling out to Model Y L vehicles in China, introduces several notable additions. First among them is an “external discharge function,” which enables V2L capability through an official adapter that Tesla plans to release later.
The feature should enable the Model Y L to power appliances, tools, or possibly even other EVs, making it extra useful for camping trips or the occasional power outages.
Other improvements include a lower temperature limit for Dog Mode, customizable low-battery settings to conserve energy while parked, and expanded personalization for the vehicle’s “Rave Cave” entertainment feature. Tesla noted that certain functions may vary depending on vehicle configuration, and rollout timing could differ by region.
Model Y L is surging in China’s SUV rankings
Despite being new in the market, the Model Y L is already making some waves in China’s top-selling mid-to-large SUVs lists. Data from Yiche showed that Tesla sold 8,221 units in September, securing fourth place in the segment behind the Leapmotor C16, Li Auto L6, and the Xiaomi YU7.
The Model Y L’s rapid ascent highlighted its strong market appeal despite a higher price point than most local competitors. Interestingly enough, the Xiaomi YU7, which is positioned closer to the standard Model Y with its five-seat configuration, topped the rankings with 22,244 units sold in September.
With Tesla’s continued free software upgrades, as well as its features like Full Self-Driving (Supervised), however, the Model Y L may have a chance at climbing China’s lists for the best-selling mid-to-large SUVs.
