More About the Solar Powered Classroom: http://go.usa.gov/b77H
The students in Aaron Sebens’ fourth grade class are installing solar panels on their classroom roof for a project that goes above and beyond a normal day in school. From researching solar panel installation, to generating funds for the project via Kickstarter, these are students who put their plans into action. Their accomplishments go beyond the classroom and stress the importance of getting people of all ages involved in renewable energy.

Lorde – Solar Power (Lyrics)
I hate the winter
Can’t stand the cold
I tend to cancel all the plans (so sorry, I can’t make it)
But when the heat comes
Something takes a hold
Can I kick it? Yeah, I can
My cheeks in high colour, overripe peaches
No shirt, no shoes, only my features
My boy behind me, he’s taking pictures
Lead the boys and girls onto the beaches
Come one, come all, I’ll tell you my secrets
I’m kinda like a prettier Jesus
Forget all of the tears that you’ve cried, it’s over (over, over, over)
It’s a new state of mind — are you coming, my baby?
Acid green, aquamarine
The girls are dancing in the sand
And I throw my cellular device in the water
Can you reach me? No, you can’t
Turn it on in a new kind of bright, it’s solar (solar, solar, solar)
Come on and let the bliss begin
Blink three times when you feel it kickin’ in
That solar power

Perovskite solar cells might revolutionize how humans generate energy from sunlight.
https://brilliant.org/ElectricFuture
First 200 people get 20% off annual premium subscription.
In this video we’ll explore the world’s fastest improving new solar technology, and provide an exclusive peek inside the lab of a team working on this breakthrough material.
Imagine an inexpensive solution of perovskite crystals that can make a photovoltaic cell so thin, that just half a cup of liquid would be enough to power a house. A solar panel so lightweight, that it can be balanced atop a soap bubble. That is known as the holy grail of solar energy. So when will we see perovskite solar panels used for a solar power system for your home? Maybe sooner than you expect.
Currently, only 2% of global electricity comes from solar power. And 90% of that, comes from crystalline silicon-based solar panels, the dominant material technology.
While abundant, silicon has downsides related to efficiency, manufacturing complexity, and pollution that prevent it from being an absolute no brainer. Emerging thin films like perovskites present a bright future. Imagine solar cars like a solar tesla, solar yachts, or a solar plane.
Solar cell technologies can be classified into two categories, wafer-based or thin-film cells. Perovskites are the leading contender in emerging thin films. Topics covered in this video include applications, perovskite crystal structure, working principle of perovskite solar cells, efficiency limits, multi-junction solar cells, shockley-queisser limit, how solar works, solar simulator, band gap, manufacturing, vapor deposition, how solar panels are made, and the future of solar power.
More and more countries of the world are beginning to use alternative energy sources, including solar. Therefore, modest rooftop panels are being replaced by “solar farms” spread over vast areas. So, the fourth-largest solar power plant in the world, Benban Solar Park is located in Egypt, covers an area of 37 square kilometers, and generates a capacity of 1,650 MW. In third place is Shakti Sthala, located in the city of Pavagada in India. Its area is 50 square kilometers and has a capacity of about 2000 MW. The second is the Chinese Hainan Solar Park. It consists of 672 photovoltaic arrays and produces 2,200 MW. What is the largest solar power plant in the world and how is it arranged? Watch in our video!

Ask This Old House home technology expert Ross Trethewey sees a robotic, ground mounted solar array that mimics a sunflower.
SUBSCRIBE to This Old House: http://bit.ly/SubscribeThisOldHouse
Steps:
1. The solar panel array is installed by securing four massive earth screws into the ground to act as a base.
2. The solar panel array is then craned off of a truck into place on top of the earth screws.
3. A trench is dug from the array to the house. Conduits are placed in the trench containing a hot, ground, neutral, and a Cat5 cable. The Cat5 cable allows the system to take in weather and location data.
4. Once the array is secured to the base and wired up, the latitude and longitude of the area is programmed into the system and it can be powered up.

I described a new (3rd) class of solar power plants (in addition to solar panels and traditional CSP) and formulated the goals that we must achieve
Now we see solar energy which is reflected from this mirror, and focused in this way, and this receiver converts solar energy into water steam. It is a prototype of one of my solar heaters. My goals are described by this formula, which leads us to the cost of solar heat at the level of 0.5 cent / kWh, and it is approximately 10 times cheaper than the cost of heat from natural gas. In addition, this cheap thermal energy can be used to generate solar electricity which is cheaper than electricity from thermal and nuclear power plants. The 2nd half of this video will describe how we can turn this thermal energy into electricity 24 hours a day, both during the day and at night.
This is the prototype of my 2nd idea for the production of very cheap solar heat. I remind you that such experiments are described in detail in other videos of my YouTube channel, and this 2nd idea aims at these goals which lead us to this cost of our solar heat, 0.5 cent / kWh.
Here we can see that the total construction cost of my mirror should be about 10 $ / sq. m. This is realistically achievable because my mirror consists of this mesh of steel rods worth $ 3, and this reflective film at a price of 25 cent / sq. m.
The mirror of my 1st idea is more expensive, and it is a mirror version of cheap stainless steel. The wholesale prices of these mirror sheets are less than 10 $ / sq. m. I remind you that I am aiming for this cost of my stainless mirror, about 15 $ / sq. m.
This is just the beginning of my experiments, which will be described in my future videos. I will also research and describe other types of mirrors for cheap solar heaters, and for example, now I am showing the idea of this American company. It is a balloon, made of this transparent film and this reflective film which focuses solar radiation. This is also a balloon, but it is very large and was proposed by this Austrian company. Its reflective film focuses solar radiation in this receiver.
This German idea is the 2nd example, and the basis of this mirror is cheap and long-lasting concrete. I plan to start experimenting with the cheapest option of similar concrete mirror in 2 months. This is the 3rd example of cheap mirrors, and I have been testing these mirrors at this my solar station for almost 8 years.
Of course, we know about traditional solar heaters for large solar power plants, and this is the 1st type of the traditional heaters. This is the 2nd traditional type of solar heaters, and this is number 3. This is type number 4, and now I am showing the fifth traditional solar heater type which is used by this new solar power plant in China.
Unfortunately, these 5 traditional types use very expensive mirrors and systems to turn them according to the movement of the sun across the sky. Their cost is about several hundred dollars per square meter, and it is 30 or 50 times more expensive than those cheap mirrors which I will research and describe in my future videos.
So, I propose the 2nd road to cheap solar electricity, which is parallel to the 1st road of these 5 traditional types of solar heaters. The 2nd road goes through experimental and economic testing of various types of extremely cheap mirrors and through maximum simplicity of our solar heaters. The simplicity gives us the following advantages: Low cost, Reliability, Small investment.
Which of the two roads is better, we can understand by similar formulas, and the winner will be the road that will offer cheaper thermal energy at the temperature we need. So, it is only competition, and I am not an enemy of these traditional ways, and I believe in their prospects and ability to win against solar panels.
In addition, we understand that I must find cheap options for such turns according to the movement of the sun. That is why I am looking for different options which are several dozen times cheaper than traditional ones, and i will describe them in my future videos.
