The U.S. solar industry has witnessed remarkable growth in the past decade while the cost of solar has declined by nearly 70 percent. Now that solar has entered the mainstream, everyday homeowners are starting to wonder how much solar could save them and how simple making the switch really could be. If you’re starting to think about installing solar panels, it’s helpful to understand the big picture for solar power. In this article, we’ll break down eight facts about solar energy that may surprise you.
Solar is now the cheapest and most abundant energy source in the world
In December 2016, the cost of building and installing new solar electricity generation dropped to $1.65 per watt, narrowly beating out its renewable counterpart wind ($1.66/Watt) and its fossil fuel competitors.
A major turning point in terms of the economics of solar vs. fossil fuels occurred in 2016 when a commercial solar provider in Dubai offered solar electricity for sale at $0.029 cents per kilowatt hour, setting a world record for solar as well as all energy sources. Today, there are 89 Petawatts (PW) of potential solar energy production available on earth, making solar the world’s most abundant available source of power.

Over a million solar systems have been installed in the U.S. alone
In early 2016, the millionth solar system was installed in the U.S., notching a milestone that took 40 years for the photovoltaic industry to reach. However, the more notable story that came with this achievement is the forecasted timeline for the next million installations, which is expected to happen in the next two years. This comparison is a meaningful illustration of solar’s rapid pace as the fastest growing energy resource in the world.
Multiple manufacturers offer a solar panel today above 20 percent efficiency
Solar panel efficiency levels have been increasing as quickly as solar costs are declining, thanks to the scientific community’s focus on the need for innovation in solar technology. To help offer perspective, just five years ago the most efficient solar panel that money could buy was 17.8 percent. In 2017, homeowners can get affordable quotes for solar panels in the 20 to 23 percent efficiency range anywhere in the U.S. In terms of solar cell efficiency, the two leading brands are SunPower and Panasonic.

Homeowners in the U.S. have achieved breakeven point with solar in as short as 3 years
The cost of solar has plummeted while the cost of grid electricity has continued to gradually rise, and the concept of the solar “break-even point” with solar has become more and more attractive. In 2017, most homeowners are seeing payback periods between five and eight years and 20-year savings estimates upwards of $20,000. Some homeowners are seeing break-even points as low as three to four years in states where utility prices are high like Massachusetts and New York.
The cost of a solar installation is now at or below $3 per watt in certain U.S. states
Not even a decade ago the cost of an installed solar system was upwards of $8 a watt, and many theorized about the day when solar could break the $4/watt threshold. Now in 2017, we’re seeing the $3.00/Watt mark take effect – quotes with pricing below $3.00 are coming in on the EnergySage Marketplace every day. The average cost per watt in 2017 is $3.16 per watt on EnergySage, meaning that an average sized system (5,000 watts) will cost $11,060 after the solar ITC subsidy.
Airplanes can fly around the world while running entirely on solar energy
Though many may be aware that solar energy can power trains, cars and even space stations, many were skeptical when Bertrand Piccard decided to fly a solar-powered plane around the world with no additional power source than the sun. In early 2016, the Swiss pilot and professional explorer departed from Abu Dhabi in the famous aircraft known as Solar Impulse II, making his much anticipated worldwide return in July. The global flight offered numerous photo opportunities and made a statement around the world about the boundless potential of solar energy.
Homeowners don’t have to install their own solar panels to go solar
People are often surprised to learn that going solar does not necessarily involve installing solar panels on your property. In 2017, the concept of shared solar or community solar – the idea of installing a massive solar farm from which hundreds or even thousands of people can source their electricity – is really taking off.
Community solar is now offered by many large utilities that have an incentive to source a certain percentage of their supplied power from renewable sources. Currently, community solar is most popular in 4 states: California, Coloardo, Minnesota and Massachusetts. However, with the many pragmatic and affordable aspects of community solar, the concept is quickly gaining popularity across the country.

Solar energy can provide power 24 hours a day, 7 days a week
One of the common concerns voiced by homeowners when considering going solar is, “What would I do at night?” This is the resource’s most evident barrier towards reaching mainstream status, and solar energy storage providers are answering the call. A number of well-regarded brands have entered the solar storage space (including Tesla, LG, and Mercedes) and new competition and innovation is causing the cost of solar storage to plummet. In 2017, homeowners can purchase solar-plus-storage systems and be completely energy independent. To learn more about storage, check out the best solar batteries available in 2017.
Overall, these eight facts offer multiple angles on solar’s growth in the recent decade and the way it has become a legitimate competitor of fossil fuel resources in 2017. If you’re considering a solar panel system in the near future, check out some tips for how solar shoppers can guarantee they’ll get the lowest price and best equipment with their installation:
Three tips for solar shoppers
Homeowners who get multiple solar quotes save 10% or more
As with any big ticket purchase, shopping for a solar panel installation takes a lot of research and consideration, including a thorough review of the companies in your area. A recent report by the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) recommended that consumers compare as many solar options as possible to avoid paying inflated prices offered by the large installers in the solar industry.
To find the smaller contractors that typically offer lower prices, you’ll need to use an installer network like EnergySage. You can receive free quotes from vetted installers local to you when you register your property on our Solar Marketplace – homeowners who get 3 or more quotes can save thousands on their solar panel installation.
The biggest installers typically don’t offer the best price
The bigger isn’t always better mantra is one of the main reasons we strongly encourage homeowners to consider all of their solar options, not just the brands large enough to pay for the most advertising. A recent report by the U.S. government found that large installers are $2,000 to $5,000 more expensive than small solar companies. If you have offers from some of the big installers in solar, make sure you compare those bids with quotes from local installers to ensure you don’t overpay for solar.
Comparing all your equipment options is just as important
National-scale installers don’t just offer higher prices – they also tend to have fewer solar equipment options, which can have a significant impact on your system’s electricity production. By collecting a diverse array of solar bids, you can compare costs and savings based on the different equipment packages available to you.
There are multiple variables to consider when seeking out the best solar panels on the market. While certain panels will have higher efficiency ratings than others, investing in top-of-the-line solar equipment doesn’t always result in higher savings. The only way to find the “sweet spot” for your property is to evaluate quotes with varying equipment and financing offers.
