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 Roadster unveiling gets pushed again, but new event details emerge
Tesla has reportedly pushed the unveiling of the Roadster once again, but there are also evidently new details about the event that the company plans to show off.
The Information reported this morning that Tesla will now unveil, for the second time, the next-generation Roadster in August, a further delay from the multiple timeline that the company had previously stated.
The report has not been confirmed or denied by Tesla at any capacity.
It also states the unveiling event will take place in Texas, the same place that Tesla executives revealed in May would be the place of manufacture for the company’s highly-anticipated supercar, which boasts a top speed of over 250 MPH and 650 miles of range, according to its website.
Tesla is also expected to showcase the SpaceX package, which will be used for faster acceleration and potentially hovering capabilities, at the unveiling event, the report states. Musk has always planned for this to happen, but now it seems it is more realistic than ever

The Roadster has had its unveiling date and manufacturing date pushed back on many occasions. It was set to start production in 2020, but the COVID-19 pandemic crippled supply chain operations, forcing Tesla to push its timeline back considerably.
However, COVID has been over for some time, and Tesla has still not managed to successfully schedule and execute an unveiling event, which is something fans and enthusiasts, as well as those who have put down a $50,000 deposit, have been waiting for.
The vehicle was close to completion last year, but Musk truly wanted Lars Moravy and Franz von Holzhausen to push the limits of the Roadster. In July of last year, Moravy said:
“Roadster is definitely in development. We did talk about it last Sunday night. We are gearing up for a super cool demo. It’s going to be mind-blowing; We showed Elon some cool demos last week of the tech we’ve been working on, and he got a little excited.”
It is important to note two things: Tesla has not confirmed these details, and the company has regularly pushed these dates back. Until Tesla sends out formal invitations with a concrete date, taking any unveiling event reports with a grain of salt is a good idea.

Tesla Model 3 has a tasty Supercharging incentive, but it’s ending soon
Tesla is offering a tasty Supercharging incentive on certain Model 3 trims, but the company has officially put a concrete end date on it, so those interested should act fast.
Tesla is offering Free Supercharging for One Year on the Model 3 Premium and Performance trims, the top two offerings of the all-electric sedan. There are three trims of the Model 3 that will have the Free Supercharging offer attached:
- Premium Rear-Wheel-Drive – $42,490
- Premium All-Wheel-Drive – $47,490
- Performance – $54,990
Tesla has now announced that this offer will expire on June 15, giving potential buyers about ten days to take advantage of the incentive.
This could be an additional incentive for car buyers to transition to electric vehicles. Many states are showing gas prices well over $4 per gallon, with the national average currently sitting at $4.22, according to AAA.
A free year of Supercharging miles would allow people to charge and travel for free, other than routine maintenance, which is already incredibly cheap compared to a gas car.

At Tesla Superchargers, peak rates, meaning prices between 8 a.m. and 10 p.m., average between $0.45 and $0.60. One year of driving at an average of 12,000 miles would cost between $1,000 and $1,500 at $0.50 per kWh. It’s a pretty good deal.
Supercharging prices have also increased recently:
Many of the Superchargers in my area just had their peak rates increased from $0.44 per kWh to $0.49, $0.52, and $0.54 per kWh
If you’re looking to save on your commute/travel for the next year, this Model 3 Free Supercharging incentive might not be a bad idea https://t.co/YDwwl4xxHk pic.twitter.com/DleURW7eqa

Tesla has used Free Supercharging to move units in the past, and it’s a great strategy for those who plan to use the car for longer commutes, cross-country drives, or do not have reliable access to home charging.
It should be noted that Tesla recommends that Supercharging be used at a minimum to preserve the life of the battery, as fast-charging is more stressful on the cells.
However, some people might not have an option, so the Free Supercharging incentive could truly be a great reason for many people to charge their cars.
The Supercharging incentive is short-term, and it is pretty rare that Tesla utilizes it, so once this offer is gone, we probably will not see it on the Model 3 for some time.

Ferrari CEO’s self-driving stance echoes Elon Musk’s — sort of
Ferrari CEO Benedetto Vigna revealed that the Italian automaker’s future will not involve self-driving, a point that echoes that of Tesla CEO Elon Musk’s — sort of.
You might be thinking, “Are you insane? Musk has been so incredibly hellbent on delivering self-driving vehicles to the public, so much so that he has even hinted that Tesla won’t need the ever-popular and widely-requested Model Y L in the U.S.”
However, when it comes to electric supercars with high-performance specs and lofty price tags, Vigna’s stance is exactly what Musk wants for Tesla’s own hypercar project, the Tesla Roadster.
🚨 Tesla Roadster vs. Ferrari Luce
Price – $250,000 vs. $640,000
Horsepower – 1,000+ vs. 1,035
0-60 MPH – 1.1s OR 1.9s vs. 2.4s
Top Speed – 250+ MPH vs. 194 MPH
Range – 620 miles vs. 280 miles https://t.co/uEgswwVLeD pic.twitter.com/XcP58ZRO6Z— TESLARATI (@Teslarati) June 5, 2026
In a new interview with Australian media outlet Drive, Vigna made it clear that Ferrari’s ambitions for the future do not involve autonomy, simply because the company’s cars are not designed for anything but manual, spirited driving.
He said:
“We will not make fully autonomous cars — loud and clear. We want the people to have fun, not the [computer] chips. We want to have a steering wheel and a man or a woman behind the steering wheel. Otherwise, why do you buy a Ferrari?”
This seems to be a reasonable assertion. Ferraris are not made for daily commutes, cross-country road trips, or bumper-to-bumper traffic. They’re made for fast, spirited driving, and many of their buyers will only put a few thousand miles on them throughout their lifetime. True, exciting, fun driving is meant to be done manually.
That is not to say Full Self-Driving or other semi-autonomous suites are not “fun,” but they are meant to take the stress out of driving. They are made for the daily commutes, the rush hour traffic, and the parking lots and garages. It’s made to take the stress out of driving.
Tesla Full Self-Driving attempts 150-mile stress test: the good and the bad
Musk had stated in an interview in early 2026 that the Roadster would also be geared toward fun, manually-controlled driving. On the Moonshots podcast with Peter Diamandis, Musk said about the Roadster:
“This is not a…safety is not the main goal. If you buy a Ferrari, safety is not the number one goal. I say, if safety is your number one goal, do not buy the Roadster…We’ll aspire not to kill anyone in this car. It’ll be the best of the last of the human-driven cars. The best of the last.”
There are cars out there that simply are meant to be driven by humans, and Ferraris and Roadsters are a few of them. Ferrari has no true advantage in developing self-driving; their cars sell at low volumes with high price tags, and their performance specs and engineering are all geared toward spirited driving.
