The Changing Landscape of Solar Power Facilities in the United States

Government rules and new technology have changed solar power in the United States. In the last ten years, solar power grew by 688%. Now, more than 4.7 million homes use solar panels.

More facilities are closing or getting canceled. This often happens because of rule changes. These changes do not mean solar power is going away. They show that the industry is changing and follow solar energy trends in the United States.


Key Takeaways

Solar power use has gone up by 688% in ten years. Now, more than 4.7 million homes use solar panels. The move from concentrated solar power to photovoltaic technology happened because it costs less and works better. This makes photovoltaic the top pick for new projects. Government rules and rewards help make solar energy cheaper for families and businesses. These things help the industry grow. There are problems like canceled projects and people in towns saying no. Still, the solar industry keeps getting bigger. Big solar projects are leading this growth. Knowing what is happening in solar energy helps people and businesses choose renewable energy.


United States Solar Facility Changes


Closures and Cancellations

Solar power facilities have changed a lot in the United States. Some big projects have stopped or did not start. The Ivanpah Solar plant in California cost $2.2 billion. It opened in 2014 but is now closing. This does not mean solar power is failing. It shows the industry is changing and getting bigger. The Esmeralda 7 solar project was going to be one of the largest. The Trump administration stopped this project before it started.

Many other projects have been delayed or canceled. About half of all siting applications for solar projects in the last five years have been delayed. Around one-third of these projects were canceled. There are a few main reasons for these problems:

  • Community opposition is a bigger problem now. In fact, 83% of solar developers say it is worse than five years ago.

  • Local ordinances can make building new facilities hard.

  • Interconnection difficulties can stop projects from happening.

Other countries also have closures and cancellations. But the United States has its own challenges. These include local rules and strong community opinions. Even with these problems, renewable energy is still growing.


Shift from CSP to PV

The types of solar technology have changed a lot in the last ten years. Developers used to build many concentrated solar power (CSP) plants. Now, most new projects use photovoltaic (PV) panels. This change happened because PV technology got cheaper and worked better.

The table below shows how PV costs went down and its share of energy went up:

Year

> 12%

Utility-scale solar has grown very fast. In 2023, solar power in the United States made 238,121 GWh. This is more than eight times what it made in 2014. Utility-scale solar now makes up about two-thirds of all solar capacity in the country. In 2023, utility-scale solar was about 8% of all electricity capacity. In 2014, it was only 1%. Small-scale solar also grew to 48 GW in 2023. This is a 20% increase from 2022 and more than six times what it was in 2014.

Note: The move from CSP to PV shows how technology and market needs change solar energy. Lower costs and better efficiency help PV become the top choice for new projects.


Current State of Solar Power in the United States


Utility-Scale Projects Overview

Utility-scale solar projects are very important for renewable energy. These big projects use new technology to make electricity. They give power to thousands of homes and businesses. There are now more than 8,100 major solar projects in the country. The total capacity is over 339 GWdc. More than 180 GWdc is working right now. This fast growth shows solar power is a big part of our energy.

Utility-scale solar projects use the newest technology. This helps lower costs and makes them work better. Developers pick places with lots of sunlight. They also choose spots close to the power grid. These projects help make electricity cheaper. They also help the country use more clean energy.

Market Share and Capacity

The solar market in the United States has three parts. These are residential, commercial, and utility-scale. Utility-scale solar has the most installed capacity. This shows it is very important for energy.

Solar capacity goes up every year. In March 2024, utility-scale solar reached 96.9 GW. Small-scale solar was at 49 GW. By March 2025, utility-scale solar will grow to 128.6 GW. Small-scale solar will reach 55.7 GW. The total solar capacity will be 184 GW. This is a 26% increase from last year.

Note: Utility-scale solar projects help solar power grow the most. Lower costs, better technology, and high demand make this part lead in renewable energy.


Facility Closures


Ivanpah Case Study

The Ivanpah solar power plant in California was once seen as a big step forward for concentrated solar power. The project started with a lot of hope and money. Ivanpah had many problems that led to it closing. The plant cost a lot to run and made less electricity than people thought it would. Ivanpah also needed natural gas to work when it was cloudy. These problems made it hard for Ivanpah to keep up with new solar technology.

Pacific Gas and Electric (PG&E) planned to buy power from Ivanpah until 2039. But PG&E stopped the deal early because Ivanpah’s electricity was too expensive. Other sources were cheaper. Ivanpah closing shows how fast the solar industry changes. New technology can make old projects less able to compete.

Ivanpah’s story shows why cost and efficiency matter for solar power plants. New solar projects often use photovoltaic panels. These panels work better and cost less.

Economic and Technological Factors

Many solar facilities in the United States have closed because of money and technology changes. Higher interest rates made it more costly to borrow money for solar projects. This made people less likely to invest and lowered the need for solar systems. Rising working capital costs made it harder for solar contractors, especially small ones, to keep their businesses running. Changes in how solar loans work have slowed down payments to contractors. This made it tough for them to manage their money.

Solar technology keeps getting better, and prices keep going down. Photovoltaic panels now work better and cost less than concentrated solar power. These improvements push older solar plants out of business. Facilities often close when they cannot keep up with new technology or control their costs.

  • High operating costs

  • Lower-than-expected production

  • Reliance on natural gas

  • Increased borrowing costs

  • Escalating working capital costs

  • Delayed contractor payments

The solar industry is still growing, but cost and technology are very important for whether a solar power plant stays open or closes.


Project Cancellations


Esmeralda 7 Overview

The Esmeralda 7 solar project wanted to bring new energy to the Southwest. The project ran into many problems before it was canceled. The Trump administration made rules that stopped federal permits. Harder tax credit rules made investors less interested. People living nearby did not want the project. There were also worries about animals in the area. All these things together stopped the project and led to its cancellation.

Many other big solar projects have been canceled too. 

These canceled projects show how hard it is to finish solar plans. High costs, new rules, and local pushback often stop projects early.

Policy and Regulatory Barriers

Federal and state rules affect solar projects a lot. New federal rules block companies from getting tax credits if they use parts from certain countries. This change could hurt California’s solar industry the most.

Sean Gallagher, a leader in the Solar Energy Industries Association, said these changes could put thousands of solar jobs and many factories in California at risk.

The Trump administration canceled the Esmeralda 7 project and added new federal rules. This made things harder for renewable energy. Some rewards were taken away, and tax credits now end sooner. Most credits will expire at the end of 2027.

Solar projects face more problems:

  • Hard permit steps can slow projects for years.

  • Wildlife rules mean long animal studies.

  • Local pushback has caused bans in some counties.

  • Connection problems make projects cost more and take longer.

These problems raise the cost of building solar projects and make cancellations more likely. The solar industry needs to find ways to lower costs and get faster approval to keep growing.


Technological Advancements


CSP vs PV Comparison

Solar power facilities in the United States use two main technologies. These are concentrated solar power (CSP) and photovoltaics. CSP systems, like those from BrightSource Energy, use mirrors to focus sunlight. The mirrors make heat, and the heat turns into electricity. CSP can store energy with Thermal Energy Storage. This means it can give power even when the sun is not out. CSP is good for big projects that need steady energy.

Photovoltaics work in a different way. Companies like First Solar and SunPower make these panels. The panels use solar cells to change sunlight right into electricity. Photovoltaics are now more popular. They are easier to put in and cost less money. Investors like photovoltaics more, even though CSP can sometimes store energy better. The low price and easy setup make photovoltaics the top pick for new solar projects.

Key reasons for the move from CSP to photovoltaics are:

  • Photovoltaics cost less and are easier to get.

  • CSP needs a lot of space, but photovoltaics fit almost anywhere.

  • Photovoltaics need less money to start a project.

PV Cost and Efficiency

Solar photovoltaics have changed a lot in ten years. The price to install solar pv has gone down. This makes it easier for families and businesses to use solar energy.

A 6 kW solar pv system cost $52,200 in 2010. Now, the same system costs only $18,000. This big price drop helps more people pick solar photovoltaics for their homes and businesses.

Many companies, like Tesla and Canadian Solar, have made solar technology better. Their products now work better and last longer. A recent survey said 43% of experts think supply chain problems are better now. This makes it easier to get new solar panels.

Solar photovoltaics are now the most used because they cost less, work better, and are easy to put in. These changes help the United States use more renewable energy.


Government Policy Impact


Incentives and Funding

Government policy helps solar power grow in the United States. Incentives and funding make solar cheaper for families and businesses. Many states give strong help for renewable energy. For example:

  • California homeowners can save 40% on installation with incentives. This help means they get their money back in six years.

  • In Texas, a small business used rebates and tax credits to cut costs by half. These savings are worth thousands of dollars each year.

  • New York’s community solar project uses state grants. People without good roofs can still use solar power. This shows how policy helps more people get clean energy.

Some policy incentives help the most:

  1. Federal tax credits lower the first cost of solar.

  2. State and local incentives, like rebates and tax breaks, add more help.

  3. Grants and loans help nonprofits and low-income families pay for solar.

Recent energy policy changes have affected solar power. If the Investment Tax Credit drops to 10%, solar projects could cost twice as much. The House budget bill may end home tax credits after 2026. These policy changes make investing in renewable energy harder.

Tariffs and Permitting

Policy also changes solar with tariffs and permitting rules. Tariffs on imported solar parts have raised costs and caused delays. The United States needs many imported solar parts. Tariffs, like the 30% charge on Chinese goods, make prices go up. Some projects are now too expensive. Permitting problems slow down new solar projects. Long waits and hard steps can delay solar for years.

Policy changes decide what happens next for solar and clean energy. Good incentives, clear rules, and faster permits can help the United States lead in renewable energy.


Solar Energy Trends in the United States


PV Market Dominance

Solar energy trends in the United States show PV technology is leading. PV panels now power the biggest solar projects in many places. In 2019, solar PV made up almost 40% of new electricity capacity. Utility-scale solar projects grew by 37% that year. These projects include some of the largest solar sites in the country. Power Purchase Agreement prices for solar are between $16 and $35 per megawatt-hour. This makes solar one of the most competitive power sources.

The solar market keeps getting bigger. In the first half of this year, developers added about 12 gigawatts of new solar capacity. By the end of the year, they expect to finish another 21 gigawatts. Solar power will give more than half of all new power capacity this year. Many states are now building their biggest solar projects ever. These projects help the environment and support renewable energy goals.

Future Outlook

Solar energy trends in the United States show strong growth ahead. The table below shows how solar capacity could change over the next ten years:

Solar generation grew almost eight times from 2015 to 2024. In 2024, the country made over 756,000 gigawatt-hours from solar and wind. This is more than three times what it was ten years ago. Experts say solar energy trends in the United States depend on policy changes. The Inflation Reduction Act and other laws will shape future growth. If these policies stay strong, the biggest solar sites will keep growing. Solar will stay important for renewable energy and help protect the environment.

Solar energy trends in the United States show PV technology, market growth, and environmental benefits will shape the next ten years.

Solar facility closures and canceled projects show big changes.

  • Solar power is becoming the main energy source.

  • Data shows solar is reaching a turning point.

  • Solar and storage costs are now close to other options, so growth will likely keep going.

New technology and strong government support help this change. In 2024, the U.S. put in almost 50 gigawatts of solar. Manufacturing grew by 190%. The Inflation Reduction Act helped start over 160 new clean energy sites.

Knowing these trends helps people see what is coming for solar energy in the United States.
