What percent of the US has solar panels?
Solar energy is one of the fastest growing clean energy sources in the US, according to the Department of Energy. Of the more than 3 million solar energy installations in the US, about 1 million were built in the last two years. That growth is especially true for residential-based solar power.
- In 2005, Congress passed a tax credit for residential solar generation.
- Since then, the number of US homes with installed solar panels increased by an average of 32% a year, according to the National Renewable Energy Laboratory,
- At the end of 2020, there were about 2.7 million residential solar systems in the US.
Solar energy production overall has increased six-fold since 2014. Residential solar generated enough power to sustain an average of about 633,000 homes in 2014 to about 1.9 million homes in 2019, according to the US Energy Information Administration (EIA).
Despite the growth, a small percentage of all homes have solar panels installed. About 3.2% of single-family detached homes have installed solar panels. Residential solar also generates a smaller percentage of total US energy production, making up less than 1% of all energy production in 2021. Solar farms and other utility-scale facilities produced enough electricity to power over 10 million homes in 2021, a total of about 111 million megawatthours.
Solar farms generated seven times more power in 2021 than in 2014. Solar energy produced through homes, businesses and other small-scale facilities generated 49 million megawatthours, which is enough electricity to power nearly 4.4 million homes in 2021.
How many solar panels would it take to power the US with Elon Musk?
One Square Mile – Speaking on Saturday at the National Governors Association Summer Meeting in Rhode Island, Elon Musk told his audience — including 30 United States governors — that it’s possible to power the nation with solar energy. “If you wanted to power the entire U.S.
- With solar panels, it would take a fairly small corner of Nevada or Texas or Utah; you only need about 100 miles by 100 miles of solar panels to power the entire United States,” Musk said.
- The batteries you need to store the energy, to make sure you have 24/7 power, is 1 mile by 1 mile.
- One square-mile.
That’s it.” Why solar? Well, as Musk explained, as far as energy sources go, we can count on solar to come through for us: “People talk about fusion and all that, but the sun is a giant fusion reactor in the sky. It’s really reliable. It comes up every day.

How many miles of solar panels would it take to power the US?
Have you ever wondered how many square miles of solar installations it would take to power the entire United States? The answer may be smaller than you think. An intriguing video by Solar City shared on the GOOD website in April 2016 takes viewers for a quick tour of what it would take to electrify the entire United States on solar energy alone.
- The map-based visual is surprising, depicting just three relatively modest-sized plots of land.
- We’re a long way from that level of deployment, but we’ve come far in a short time.
- In 2015, 0.6% of utility generation in the U.S.
- Came from solar.
- To increase that number to 100%, we would need to produce 4 million gigawatt-hours (GWh) of solar energy annually.
To produce 1 GWh of solar power, you need approximately 2.8 acres of land—or roughly 11.2 million acres (17,500 square miles) to generate 4 million GWh of clean energy. By these calculations, it would only take 0.6% of the total surface area of the continental United States to power the entire country with renewable solar power.
- That’s right, less than 1%.U.S.
- Solar energy production continues to increase steadily.
- In 2016, the amount of power contributed by solar rose to 0.9% of U.S.
- Electricity generation at utility-scale facilities, according to the U.S.
- Energy Information Administration (EIA),
- In June, the EIA said that for the first time in March, wind and solar accounted for more than 10% of utility electricity generation in the U.S.
during a single month. But even that milestone represents a very conservative number. Keep in mind that it does not include the many thousands of gigawatt-hours generated by the distributed solar assets deployed across more than a million rooftops and ground-mount solar installations.
Echoing the information shown in the SolarCity video, Tesla CEO Elon Musk believes that not only is it theoretically possible to power the entire country but that this vision is achievable with less land than then we think. In July, he reminded more than 30 state governors at the National Governors Association meeting how much real-estate is needed to make sure America can run completely on solar energy.
“If you wanted to power the entire United States with solar panels, it would take a fairly small corner of Nevada or Texas or Utah,” he explained. “You only need about 100 miles by 100 miles of solar panels to power the entire United States. The batteries you need to store the energy, so you have 24/7 power, is 1 mile by 1 mile.
- One square-mile.” That’s just 101 square miles, or as Elon says, “a little square on the U.S.
- Map.” To put this into perspective, that’s about 10% of the 1045 square-mile area of Rhode Island, the smallest U.S.
- State—although admittedly the desert Southwest has better insolation than New England.
- While these calculations are admittedly of the back-of-the-envelope variety, Elon’s figures do take into account the element of battery storage, the game-changing option that has seen rapid market growth and opened many minds about the long-term potential for pairing solar and storage in the industry.
What his grand vision may not be considering is the net battery capacity necessary to provide power 24/7 for a few days should the need arise as well as the operations and maintenance necessary to keep the system running smoothly. Let’s not forget the additional land needed to incorporate things like service roads, operational facilities and transmission lines either.
- Elon isn’t really suggesting that we build a multi-terawatt-scale solar array in one place.
- For cost, weather, logistical, infrastructure and other reasons, such a project would not be feasible.
- But his thought experiment shows just how much power generation we can get from the mightiest energy source of all, using relatively small amounts of land and many billions of PV panels.
While we love to see solar installations of all sizes come online, we wish the road to building a brilliant tomorrow were faster and less expensive. But no one ever said kissing fossil fuels goodbye would be easy. The burgeoning interest and investment in renewables speak for themselves.
With more big companies, utilities, small businesses, universities, government entities, communities, and, of course, homeowners getting on board, a wide variety of people understand the compelling economic and environmental benefits of solar. If every person who is now benefiting directly from solar power stood side by side, I wonder how long the line would be? Then again, that line just keeps growing every day.

What would happen if everyone has solar panels?
Widespread installation of solar panels would have cascading effects on the climate One of these days, we are all going to have to make the switch to renewable energy – if not out of concern about climate change then simply because fossil fuels will eventually run out.
But even sustainable energy technologies may have an effect on global climate, according to a study published yesterday in Nature Climate Change, In the study, researchers used computerized climate models to investigate what would happen if the world’s entire energy supply were converted to solar. They assumed that solar panels would be installed in the major desert regions of the world, where the supply of sunlight is greatest, and in urban areas, where the demand for power is greatest.
In areas covered by solar panels, less solar radiation gets absorbed by the Earth, because it gets absorbed by the solar panels (and converted to electricity) instead. Widespread installation of solar panels would decrease absorption of solar radiation by up to 19% in desert areas, the researchers found.
- In turn, this has cascading effects on the climate.
- At a global scale, the changes from solar panel installation are small compared to those predicted to occur due to greenhouse gases.
- But at a regional level, some of these climatic shifts could be significant, the researchers say.
- Average temperature in desert regions would decrease by about 2 degrees Celsius.
Desert precipitation could also decrease by over 20%, largely because the presence of solar panels also reduces cloud cover. According to the researchers’ model, this desert cooling would lead to changes in in wind patterns, a shift in the location of the jet stream, and altered precipitation levels for many regions.
- Much of Asia, parts of the Middle East, Australia, and the tropical Pacific would lose up to 25 centimeters of average annual precipitation.
- Instead, that precipitation would shift to Europe, the North Pacific, western North America, tropical Africa, and the southeast Indian Ocean.
- These patterns are opposite to those predicted to arise from greenhouse gas-induced warming.) Regions to the East, or downwind, of desert areas covered by solar panels would also cool off by about 1 degree Celsius.
(Exceptions are India and the West Coast of North America, which, due to lower precipitation and altered wind patterns respectively, warm by about 1 degree Celsius instead.) The study presents an extreme scenario: the researchers assumed that 100 percent of land area in cities and deserts would be covered with solar panels, which isn’t realistic.
And those solar panels would generate almost 800 terawatts of power, much more than the world is likely to need. But the researchers say this sort of exercise can reveal mechanisms underlying the climate system and help interpret the results of more realistic modeling exercises. So they also constructed a version of their model that more accurately reflects likely future demands for power.
In this scenario, solar panels would be installed across urban areas worldwide and in a portion of the Egyptian desert, covering about 10% of the total land area devoted to solar panels in the first version of the model. Here the patterns of surface temperature change are similar in broad strokes to those seen in the extreme version of the model, but much more modest.
For example, global temperature would decline by about 0.04 degrees Celsius, the researchers found. This smaller global solar grid would produce about 59 terawatts of power per year. That’s still plenty sufficient to cover global demand for electricity, which the Intergovernmental Panel on Climate Change has estimated to be, at most, 45 terawatts per year by 2100.
So the good news is that the sun provides more than enough energy to meet the demands of humanity for the forseeable future. But the disconcerting news is that those demands are so great that even at our most sustainable, we humans are likely to leave a marked environmental footprint.
How many solar panels could power the world?
How Many Solar Panels Would It Take to Power The US? – Using the same calculations above, but replacing the world consumption (23,696 TWh) with US consumption (4,479 TWh), we learn that the US would require 3.5 TW of solar power (assuming 3.5 hours of sun on average).
- That means that we’d need 10 billion 350W solar panels to electrify America.
- That’s 19.5% of the entire world’s electricity consumption! (America’s population is about 4.25% of the entire world.) In terms of surface area, using the roughly 4 acres for 1 MW of solar farm, it would take 21,913 square miles of solar to power America.
That’s a little smaller than West Virginia, but still bigger than 9 other states.
What is the largest solar farm in the United States?
Solar Star, Kern, and Los Angeles Counties – Solar Star is the largest solar farm in the US. When the farm was set up on June 2015, it was the biggest solar farm in the world. Solar Start has 1.7 million solar panels spread out in more than 13 square kilometres in Kern and Los Angeles Counties, California.
- That is nearly the size of 142 football fields or 4 times the size of Central Park! The project is divided based on two separate installations — Solar Star 1 and Solar Star 2.
- The first one has a capacity of 314MW and the second one has 265MW.
- Overall, Solar Star generates 579 MW of energy, which is enough to provide electricity to almost 255,000 households.
Building this solar farm created nearly 650 jobs over three years. Also, as reported by “CleanTechnica,” Solar Star had created 40 maintenance jobs, including 15 full-time site positions, during its lifetime. Here are a few more facts about the Solar Star project, collected from the California Energy Commission:
Solar Star was established on an altered land. It means that the land had already been altered or used by people.The solar panels on the farm get cleaned up automatically by using minimal water.The solar panels use a single-axis tracker to follow the sun’s movement throughout the day. This feature makes the panels nearly 25% more efficient than motionless panels.The net environmental impact of this project is significant. The solar output of this farm is taking 108,000 cars off the road annually.
The Solar Star project was started in 2013 and completed in 2015. After it was completed, the farm has more than 1.7 million solar panels, was already producing more than 170 MW to the California grid. Solar Star has completed its fourth year in June 2019, and it is still the largest solar farm in the country in terms of power generated.

How many solar panels would it take to power New York?
Powering New York Imagine that overnight all power infrastructure in New York were to disappear. Then, starting from scratch, we could build anything we wanted: a giant solar array that stretches to the horizon, the world’s biggest windfarm, or a mega nuclear facility.
- What would it take to power the Big Apple for a year with each individual energy source? We’ve crunched the numbers for oil, natural gas, liquefied natural gas, solar, wind, and hydro.
- Then, we visualized what is needed for each to be hypothetically feasible as the city’s only source of energy.
- Note: we’ve included some notes on our calculations at the bottom of this page.) The results are quite mind boggling.
For example, to facilitate New York City’s average power needs, you would need 12.8 km² of solar panels, enough to cover a good chunk of New Jersey. The average distance one can see into the horizon is 5km, which means that one would be able to see solar panels as far as the eye can see.
- Another interesting example: powering New York City with hydroelectric based on average power needs would mean 14 Hoover Dams, each which produce about 4.2 billion kWh per year in energy.
- Using wind power, about half of Long Island would need to be converted into the world’s biggest wind farm to power New York City.
That’s exponentially bigger than the current biggest wind farm in the United States, which is in the Tehachapi-Mojave region in California and has a nameplate capacity of 1,320 MW. Quick notes on calculations This presentation is for visualization purposes, and isn’t fully realistic on a technical basis because in reality, the supply and demand of energy is not constant.
- The city’s power needs fluctuate during base and peak load times.
- In terms of supply, the wind is not always blowing and the sun isn’t always shining.
- We based our numbers off of average electricity consumption, assuming that energy can be banked in times of surplus and used during times of deficiency.
We used some assumptions for the efficiency as well. For example, that a power plant burning oil has an efficiency of, or that our wind farm uses, Use and share this presentation Feel free to use or share this presentation by either:
