INTERESTING FACTS ON SOLAR ENERGY :
1. 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. To learn more about how to compare solar and fossil fuels apples to apples, check out our full explanation.
2. 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.
3. 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 2018, 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 SunPowerand Panasonic. To learn more about how solar panel efficiency has changed over time, checkout our entire writeup.
4. 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 2018, 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.
5. 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 2018, 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 2018 is $3.16 per watton EnergySage, meaning that an average sized system (5,000 watts) will cost $11,060 after the solar ITC subsidy.
6. 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.
7. Homeowners don’t have to install their own solar panels to go solar

Bro super

[@indian4525]

Anna but accelerated charge produce alternating current in solar cells why random electrons can't produce alternating current?

[@VKARTHIKEAYAN]

Nice

[@englishwithkalai8690]

Gd explanation bro

[@vmuthukumar12tha25]

Wow super bro good explanation wow wow semma

[@VijayaKrishnaVK]

நன்றி நண்பா!....

👍👍

[@indian4525]

Anna how AC current converted into dc current pls anwer me

[@bennia3591]

What is eva sheet

[@parthi9821]

How to work battery in Tamil animation,

[@vsrinivasanrvenkatasubrama9550]

I want to talk to you regarding solar system my phone is

[@parthi9821]

What is DC current and current direction in aimation

[@indian4525]

DC is direct current it means it has straight direction

[@indian4525]

AC is alternating current it has sinusoidal direction

[@indian4525]

Sinusoidal means up and down direction

[@indian4525]

Can u understand?
