Fact #18: Leonardo da Vinci was the first to predict large scale solar power.6
Fact #19: Photovoltaic solar panels are made of silicon, which is the second most abundant element on Earth after oxygen.7
Fact #20: Solar energy is generated as DC (direct current) power. Typically, solar panels are installed with an inverter to convert DC power to usable AC (alternating current) power.
Fact #21: “Space-based solar power” is the idea of harnessing solar power in space, where there is no night time or atmosphere, to capture more energy than solar panels on Earth.3
Fact #22: In the United States, southern facing solar panels perform best.6
Fact #23: Solar panels have no moving parts and require virtually no maintenance.1
Fact #24: China built a 250-acre solar farm in the shape of a panda.13
Fact #25: In 2015, solar accounted for only 1% of the world’s electricity generation.3
Fact #26: In 2019, 40% of all new electric capacity added to the grid came from solar.12
Fact #27: Solar panels can last for over 40 years.5
Fact #28: Contrary to popular belief, solar panels still work on cloudy days.6
Fact #29: Conventional solar panels can produce a range of 100 to 320 watts of electricity each. However, high performing solar panels can produce up to 400 watts per panel.
Fact #30: Many states and towns are mandating solar panels on all new buildings.
Fact #31: Solar energy produces no water pollution after installation.1
Fact #32: Solar can power your home at night if you add a battery.
Fact #33: In many parts of the world, solar is now cheaper than coal.3
Fact #34: The price of solar panels have reduced by 80% since 2008.4
Fact #35: Las Vegas, Nevada is the largest city to operate on 100% renewable energy, which is largely solar power.7
Fact #36: Burlington, Vermont was the first city in America to achieve 100% clean energy generation for its residents.7
Fact #37: Solar power does not create any noise while producing energy.1
Fact #38: Solar energy is the quickest solution to energy in times of crisis.1
Fact #39: Solar panels actually perform more efficiently in cooler temperatures.
Fact #40: Thermal solar panels heat water with the sun’s warmth, while photovoltaic (PV) solar panels produce electricity with the sun’s light.
Fact #41: Monocrystalline solar panels are darker in color and more efficient than polycrystalline panels, which are generally more blue in appearance.
Fact #42: Most solar panels are rigid, although flexible solar panels are often used for recreational vehicles or small-scale energy production.19
Fact #43: Solar technology can even be applied to paint.3
Fact #44: Solar energy is the fastest growing energy sector in the world. Solar demand is currently at an all-time high.8
Fact #45: Old coal mines are now being converted into solar power plants.17
Fact #46: Increased demand for solar is leading to a greater demand for electric vehicles (EVs).
Fact #47: The solar industry is creating jobs five times faster than the job market.10
Fact #48: In 2017, renewable energy jobs, including solar, overtook the number of jobs related to fossil fuels.10
Fact #49: A home with solar panels reduces its 30-year carbon footprint by 100 tons.7
Fact #50: Over 2 million solar systems have been installed in the United States.
Fact #51: Sheep are being used for vegetation maintenance on solar farms to reduce operations costs.15
Fact #52: Solar panels are exempt from property taxes in many states including Massachusetts and increase the value of a home more than a complete kitchen remodel.7
Fact #53: Homes with solar panels sell for approximately 4.1% more than homes without.14
Fact #54: Solar energy is free, but solar panels cost money. However, most people still save money every month paying for panels rather than electricity from the grid.
Fact #55: Most customers rent or finance their solar panels.
Fact #56: Popular music festivals around the world are embracing solar, geothermal, and other natural sources of power.16
Fact #57: Many US states allow solar owners to sell back excess power to the grid, which is called net metering.
Fact #58: Adding solar panels to your home or business lowers your electricity bills significantly. In most cases, you’ll even receive incentives for the energy your system produces.
Fact #59: China is currently the global leader in installed solar energy capacity.5

Fact #61: Walmart is one of the largest commercial adopters of solar power.5
Fact #62: One of the most common reasons people go solar is because someone in close proximity to them did.
Fact #63: Investing in solar power pays for itself over time. Our customers often break even and are cash-flow positive within five years.
Fact #64: Even oil and gas companies like Exxon Mobile use solar panels on oil rigs.7
Fact #65: Breweries are utilizing solar to cut operation costs. Heineken powers its brewing in the Netherlands with over 16,000 solar panels.18
