This is Mike and today I was consolidating my scrap electronics drawer and found this A broken calculator. I decided to take the screen and the solar cell out. I removed the back panel and noticed the lack of wires to the cell. I checked for broken solder connections and found none. The solar cell is fake! I just wanted to show you this ridiculous example of how cheap electronics can get. Christianne picked up a nearly identical one for me, so I could check its solar cell too. I disassembled the new one.
Solar Panel Calculator How to Calculate your Solar Panel Needs
Solar panel calculator you're looking for a solar power Kula now a whore solar panel calculator is is a world or not sign Austell we if a you know some uh those laws in the garden with solar things on stuff sation really a ollie ago very curious about solar power and and hell ok to use it in my home and no I went on I research camp einen and look all got lost the reason this I much information so many different hell so many different systems you can use.
That's almost overwhelming a a thats you know I which was it said I'm butts also Atleo to fund a system where with a gentleman is put it all together in one place and and we should say on the system for months before did occurs bicycle understood what he said and my pal bill turn from hundreds of dollars every month 20 and sometimes you get a little check back or sometimes repin few bucks but by sickly of water they'll and and it's just a relief to know is that.
You know when when that so many months comes around the electricity bill isn't gonna be one of them so a look how either just in the tutorial here or just in the description though basically solar panel calculator to a link to to another tutorial which will go to the system Lord the bicycling told me held see what they'll my electricity bill so I with every penny have a look it's only a few hawk's eye it's with the recent driver implemented I cuando se gives you bonus uva win civil switch you know on.
Solar Power Calculators Part 1 An Introduction to the Solar Calculators
Hi, this is Finn Peacock from SolarQuotes.au and in this tutorial we're going to go through how the hell do you work out what the pay back of your solar power system will be I'm assuming that you've got a quote for a solar power system and that should obviously have a price on it. And also it should have an estimated power output in kilowatthours. If it hasn't chuck it in the bin find another installer as that's fairly important! Once you've got that information this is how you work out whether it's financially viable.
To buy the thing. If we go to SolarQuotes.au then we just go down to learn about solar power and click on the solar pay back calculator. Okay there's 3 calculators I've created on the website and the reason there are three is that they're essentially three ways to pay for a solar system and and how you pay for the solar system will affect cash flows of owning the system and, you know, whether your solar system is cash flow positive or not is one of the major factors.
That you're going to take into account when you're weighing up whether this thing's financially viable or not. So the first calculator, I've called it the electricity savings calculator. That's assuming you're paying cash for the solar system. So that compares the economic of owning a solar system with the situation that you would be in if you didn't which would be collecting interest on the money that's in the bank The second option is to add it to your mortgage I'm actually surprised more people don't do this because well you can try for yourself when you put the numbers in generally.
A good solar system at a decent price will pay for itself from month 1. and but And what Imean by that is the amount you save on your electricity will be more than the extra repayments on your mortgage so you actually save money every month. Usually. I mean put the numbers in see if it works for you. But generally, it can be quite a good idea and the third option which is usually the least, the most difficult one to make work in terms of getting a positive cash flow anyway is if you finance it with the.
Loan and the the reason there is that it that these loans tend to be quite short term and have quite high interest rates so it can be quite hard to make the loan repayments be less than what you save in electricity. But again you know put the numbers in and see if it works for you. In the next tutorial I will walk you through all the fields in the first calculator because all the fields pretty similar and and I'll explain what they are if you want change them from the default what numbers you put in.
Okapi Fan Control Systems for Solar Collector Air Heaters
These are two 4' x 8' solar air heater panels They only took a few days of work and cost under CA$400 to make The sun shines on the panels on a cold December day But there's a problem. Due to convection, all the heating occurs at the ceiling Which this thermal image clearly confirms If you direct the hot air from the panels to the floor, furniture and other objects You will more efficiently heat the room We solved this problem by using our innovative fan control system After just a couple of hours of solar heating.
Art Inspired Solar Cells MichEpedia MconneX
The solar industry is very, very focused on improving efficiency and reducing the cost. Our attempt here with this research is to propose a new way of looking at these structures and saying, well, you can use existing materials and nothing really needs to change very much. You just shape them in different ways that gives you this benefit. Kirigami is a Japanese art that's related to origami where origami is really about folding of things and kirigami is about cutting things. A colleague of mine who is an artist, Matthew Shlian, he had some interesting.
New shapes and when you pulled on the sheet of paper the cuts would sort of begin to buckle and deform in a very controlled way and so I realized at that point that we could look at that structure as a hyperminiaturized version of solar trackers. Conventional solar tracking has been used for many, many years. The mechanism itself cost quite a bit of extra money. What people end up doing as they say, well, since the mechanisms gonna cost all this extra money. we might as well put a really big panel and then eventually you end up with.
Something that's really big and really heavy. When you think about putting this type of thing on a rooftop it's very very difficult and in most cases is just purely impossible. It was a fairly lengthy process because the things that you do in paper don't automatically translate to other materials and so I started talking to my colleague, Stephen Forrest, about using some of their very high efficiency gallium arsenide solar cells. They're pretty thin, less than 2 microns thick that's ten to fifty times thinner than the thickness of a human hair. What the new design allows us.
To do in contrast to conventional tracking is it basically allows us to work with the same form factor. It doesn't catch the wind, it doesn't weigh any more than a conventional solar panel might and the thing that it buys you is that you can use less semiconductor to gather the same amount of energy. A third less material to generate the same total amount of energy that you would otherwise. Which means that in turn that I could decrease the cost of installation because there are fewer panels to install but you do require little bit of extra area. When you.
Multiply it by the total number of solar installations it's kind of like a billion dollar value proposition potentially. I guess it looks simple enough, kind of like something that you could do on your kitchen table, things don't have to be complicated for them to work. If this can be shown to be quite reliable, then the net benefit could be quite big. V.O. These candies which are already pretty soft should be about 10 to 100 times stiffer than the silicone. So the material that we're working with in the lab is really really soft.
Energy 101 Concentrating Solar Power
Bjbj Take the natural heat from the sun, reflect it against a mirror, focus all of that heat on one area, send it through a power system, and you've got a renewable way of making electricity. It's called concentrating solar power, or CSP. Now, there are many types of CSP technologies. Towers, dishes, linear mirrors, and troughs. Have a look at this parabolic trough system. Parabolic troughs are large mirrors shaped like a giant U. These troughs are connected together in long lines and will track the sun throughout the day. When the sun's heat.
Is reflected off the mirror, the curved shape sends most of that reflected heat onto a receiver. The receiver tube is filled a fluid. It could be oil, molten salt something that holds the heat well. Basically, this super hot liquid heats water in this thing called a heat exchanger and the water turns to steam. The steam is sent off to a turbine, and from there, it's business as usual inside a power plant. A steam turbine spins a generator and the generator makes electricity. Once the fluid transfers it heat, it's recycled and used over and over.
And the steam is also cooled, condensed and recycled again and again. One big advantage of these trough systems is that the heated fluid can be stored and used later to keep making electricity when the sun isn't shining. Sunny skies and hot temperatures make the southwest U.S. an ideal place for these kinds of power plants. Many concentrated solar power plants could be built within the next several years. And a single plant can generate 250 megawatts or more, which is enough to power about 90,000 homes. That's a lot of electricity.
How to do Fluorescence with Sunlight
Hi Folks! Here's a neat way I came up with to demonstrate fluroescence, and as you can see, it can make some nice effects. For those who don't know, fluorescence is what happens when you shine a light of a certain wavelength on a fluorescent material, ordinary tonic water in this case. Normally tonic water is transparent but when you shine ultraviolet light through it, it gives off this blue light, it fluoresces blue. Well, while making a tutorial about fluorescence and TEA lasers I needed some chlorophyll. Chlorophyll is the molecule that makes plants.
Green. So to get some I chopped up some fresh spinach. Then I put it in a container, along with some rubbing alcohol. And after leaving it for twenty minutes, I strained out a green liquid. But was it chlorophyll When chlorophyll fluoresces it gives off red light. But I didn't have have a suitable light source, until I realized I did, the sun. And sure enough, in direct sunlight it looks reddish. And by concentrating the sunlight with a magnifying glass, making brighter light, it really gives off red light.
And here's the tonic water again, in an open cup. And here's the tonic water in the blackened jar. Another one to try is fluorescein, which is found in highlighter markers. Simply open it up, and swish the tube that you find inside in tap water, giving it a squeeze to get the fluorscein out. Here's the fluoroscein in an open cup. And here it is in the blackened jar. Well, thanks for watching! See my channel, rimstarorg for more neat tutorials like this. That includes the one I mentioned where I talk more about fluorescence.
