25 Amazing Facts About Solar

Are you skeptical of solar energy? Our solar expert has 20 incredible facts that show how far the industry has come in just a few years and how big this opportunity is both in the U.S. and abroad.

Apr 20, 2014 at 1:25PM

In the past few years alone, the solar industry has gone from a clean energy source that required subsidies just to stay afloat to a full-fledged economic force. Solar energy is now passing grid parity in Europe, the southwestern U.S., South America, South Africa, and many other parts of the world. As costs fall, even more locations will find solar power to be economical, opening up a global electricity market worth over $1 trillion annually.

Here are just a few amazing statistics that show just how far solar energy has come and how big an opportunity it is for investors.

A global look at solar
To start, let's put the global solar industry in some perspective.

  • 37 GW: The number that global solar installations hit in 2013, according to the most recent data from Solarbuzz. That's enough to power over 6 million homes. 
  • 50 GW: How big the solar market is projected to be in 2014, 35% higher than last year.  
  • 12 GW: The amount of solar installed in China last year, followed by 9.5 GW in Japan, 4.4 GW in the U.S., and 3.3 GW in Germany.
  • 13.28 Euro cents/kW-hr: Germany's feed-in tariff rate for small rooftop systems, which is one-third of the average electricity cost for households of 29.2 Euro cents/kW-hr.
  • 9.19 Euro cents/kW-hr: Germany's feed-in tariff rate for large solar systems. 
  • 70 MW: The size of the largest merchant solar power plant (meaning the power will be sold to the grid at market prices) in the world, which SunPower (NASDAQ:SPWR) is building in Chile. The project will be 20% owned by the oil giant Total (NYSE:TOT), which also owns 66% of SunPower. 
  • 4 GW: The size of the solar project being planned in India, which would easily be the world's largest. Its estimated cost is $4.4 billion. 
  • $109 billion: The amount of money Saudi Arabia -- yes, the oil exporter -- plans to spend to meet its goal of a 100% renewable-energy future. The plan is beginning to take shape, starting with an expected 1 GW tender later this year. If that doesn't make oil companies nervous, I don't know what will.

A look at U.S. solar
The U.S. solar market has gone through many changes over the past decade and has been a political punching bag for years. But the industry now is at a sustainable cost structure, and even the pending reduction of the investment tax credit can't stop solar growth. Here's how far it's come in just a few years. (Note: Most of the following data is from the GTM Research/SEIA U.S. Solar Market Insights Report.)

  • 29%: The percentage of new electric capacity that installed solar accounted for in the U.S. in 2013, up from 10% a year before.
  • 41%: The growth in U.S. solar installations in 2013 to 4.75 GW.
  • 800,000: The number of homes that can be powered with the solar power installed in 2013 alone. 
  • $2.59: The per-watt weighted average cost to install solar power in the U.S. in Q4 2013, down 15% from a year earlier.
  • 34%: The amount residential solar installations have fallen in cost from Q1 2010 to Q4 2013 in the U.S., to $4.59 per watt.
  • 59%: The amount utility-scale solar projects have fallen in cost in the same timeframe, to $1.96 per watt. 
  • 55%: The percentage of of all U.S. residential solar installed in California in Q4, up from 43% in Q1 of 2010. No doubt, California dominates solar. 
  • 142,698: The number of people employed in the solar industry as of last November, up 19.9% from a year earlier, or 10 times the national average growth rate.  
  • 99%-plus: The amount the cost of solar panels has fallen since 1978, when RGS Energy sold the first retail solar panel for $100 per watt. Today, a standard solar panel costs around $0.65 per watt.  
  • 3 minutes: How quickly SolarCity (NASDAQ:SCTY) recently said it's signing a new solar customer -- every three minutes in the 14 states it operates in.

Solar is already big business
The solar industry has gotten a bad rap after the failure of high-profile companies like Solyndra, but it's a huge business that very successful investors are betting big on. 
  • 579 MW: The size of the largest solar power plant in the world, currently being built by SunPower. When completed, this single project will provide enough power for 400,000 homes.
  • $2.5 billion: The amount Warren Buffett's Berkshire Hathaway subsidiary MidAmerican Energy paid for SunPower's 579 MW Solar Star project. 
  • 377 MW: The size of the Ivanpah concentrated solar system, which NRG Energy (NYSE:NRG), Google, BrightSource Energy, and Bechtel recently completed. It is the largest solar concentrator in the world and will provide enough power for 140,000 homes.
  • 4.8% and 4.59%: The yields on SolarCity's first two securitization deals. Solar power is becoming big business in the financial industry, and in the past six months, SolarCity has completed the industry's first two securitization deals for $54.4 million and $70.2 million, with interest rates of 4.80% and 4.59%, respectively. 
  • $5.7 billion: Solar financing is just getting started, and GTM Research predicts that the residential market will see financing grow from $1.3 billion in 2012 to $5.7 billion by 2016. This is big business, folks. 

Putting the potential power of solar in perspective
Still skeptical of solar energy? Think it'll only be a bit player in our energy future? Take a look at these numbers.

  • 600%: The percentage of the United States' electricity demand you could generate if you filled the Mojave Desert -- which is 25,000 square miles and covers about 0.66% of the United States' land mass -- with SunPower's most efficient production solar panels. Put another way, this one desert could generate more than enough energy to power the world.
  • 59.1%: The amount of Germany's energy that came from renewable energy on a sunny day late last August. Of that amount, 11.2% came from solar, and as GTM Research cheekily pointed out, the grid did not explode.

Investing in solar isn't as scary as it used to be
In 2012, solar manufacturers took it on the chin as oversupply hit the market and module prices dropped like a rock. But some manufacturers and installers are now separating themselves and provide incredible opportunities for investors.

Investors can get solar exposure through manufacturers like SunPower or First Solar, which also build projects, or through downstream installers like SolarCity. There are also ways to play the owners of these projects, which are collecting cash for 20 years or more from them -- companies like NRG Energy or its new offshoot, NRG Yield, which is one of the first yieldcos, which are companies that own solar projects and pay a dividend with the cash flow. 

Solar is a growing business, and I hope these statistics put both the progress and potential for this industry in perspective. The growth cycle for solar has just begun, and investors who get in early can ride the wave for the next few decades. 

Everywhere you look, the U.S. energy industry is growing
What's amazing about the progress in solar, wind, oil, and gas is that it was only a decade ago that the U.S. was worried about energy imports. Today, the situation has been turned on its head and all of these energy sources are bringing the country close to energy independence.

1 Key Step to Get Rich

Our mission at The Motley Fool is to help the world invest better. Whether that’s helping people overcome their fear of stocks all the way to offering clear and successful guidance on complicated-sounding options trades, we can help.

Feb 1, 2016 at 4:54PM

To be perfectly clear, this is not a get-rich action that my Foolish colleagues and I came up with. But we wouldn't argue with the approach.

A 2015 Business Insider article titled, "11 websites to bookmark if you want to get rich" rated The Motley Fool as the #1 place online to get smarter about investing.

"The Motley Fool aims to build a strong investment community, which it does by providing a variety of resources: the website, books, a newspaper column, a radio [show], and [newsletters]," wrote (the clearly insightful and talented) money reporter Kathleen Elkins. "This site has something for every type of investor, from basic lessons for beginners to investing commentary on mutual funds, stock sectors, and value for the more advanced."

Our mission at The Motley Fool is to help the world invest better, so it's nice to receive that kind of recognition. It lets us know we're doing our job.

Whether that's helping the entirely uninitiated overcome their fear of stocks all the way to offering clear and successful guidance on complicated-sounding options trades, we want to provide our readers with a boost to the next step on their journey to financial independence.

Articles and beyond

As Business Insider wrote, there are a number of resources available from the Fool for investors of all levels and styles.

In addition to the dozens of free articles we publish every day on our website, I want to highlight two must-see spots in your tour of fool.com.

For the beginning investor

Investing can seem like a Big Deal to those who have yet to buy their first stock. Many investment professionals try to infuse the conversation with jargon in order to deter individual investors from tackling it on their own (and to justify their often sky-high fees).

But the individual investor can beat the market. The real secret to investing is that it doesn't take tons of money, endless hours, or super-secret formulas that only experts possess.

That's why we created a best-selling guide that walks investors-to-be through everything they need to know to get started. And because we're so dedicated to our mission, we've made that available for free.

If you're just starting out (or want to help out someone who is), go to www.fool.com/beginners, drop in your email address, and you'll be able to instantly access the quick-read guide ... for free.

For the listener

Whether it's on the stationary exercise bike or during my daily commute, I spend a lot of time going nowhere. But I've found a way to make that time benefit me.

The Motley Fool offers five podcasts that I refer to as "binge-worthy financial information."

Motley Fool Money features a team of our analysts discussing the week's top business and investing stories, interviews, and an inside look at the stocks on our radar. It's also featured on several dozen radio stations across the country.

The hosts of Motley Fool Answers challenge the conventional wisdom on life's biggest financial issues to reveal what you really need to know to make smart money moves.

David Gardner, co-founder of The Motley Fool, is among the most respected and trusted sources on investing. And he's the host of Rule Breaker Investing, in which he shares his insights into today's most innovative and disruptive companies ... and how to profit from them.

Market Foolery is our daily look at stocks in the news, as well as the top business and investing stories.

And Industry Focus offers a deeper dive into a specific industry and the stories making headlines. Healthcare, technology, energy, consumer goods, and other industries take turns in the spotlight.

They're all informative, entertaining, and eminently listenable ... and I don't say that simply because the hosts all sit within a Nerf-gun shot of my desk. Rule Breaker Investing and Answers contain timeless advice, so you might want to go back to the beginning with those. The other three take their cues from the market, so you'll want to listen to the most recent first. All are available at www.fool.com/podcasts.

But wait, there's more

The book and the podcasts – both free ... both awesome – also come with an ongoing benefit. If you download the book, or if you enter your email address in the magical box at the podcasts page, you'll get ongoing market coverage sent straight to your inbox.

Investor Insights is valuable and enjoyable coverage of everything from macroeconomic events to investing strategies to our analyst's travels around the world to find the next big thing. Also free.

Get the book. Listen to a podcast. Sign up for Investor Insights. I'm not saying that any of those things will make you rich ... but Business Insider seems to think so.
