Production description

A solar panel is a collection of solar cells. Lots of small solar cells spread over a large area can work together to provide enough power to be useful. The more light that hits a cell, the more electricity it produces, so spacecraft are usually designed with solar panels that can always be pointed at the Sun even as the rest of the body of the spacecraft moves around, much as a tank turret can be aimed independently of where the tank is going.

A photovoltaic (in short PV) module is a packaged, connected assembly of typically 6×10 solar cells. Solar Photovoltaic panels constitute the solar array of a photovoltaic system that generates and supplies solar electricityin commercial and residential applications. Each module is rated by its DC output power under standard test conditions, and typically ranges from 100 to 365 watts. The efficiency of a module determines the area of a module given the same rated output – an 8% efficient 230 watt module will have twice the area of a 16% efficient 230 watt module. 

solar modules use light energy (photons) from the sun to generate electricity through the photovoltaic effect. The majority of modules use wafer-based crystalline silicon cells or thin-film cells based on cadmium telluride or silicon. The structural (load carrying) member of a module can either be the top layer or the back layer. Cells must also be protected from mechanical damage and moisture. Most solar modules are rigid, but semi-flexible ones are available, based on thin-film cells. These early solar modules were first used in space in 1958.

Depending on construction, photovoltaic modules can produce electricity from a range of frequencies of light, but usually cannot cover the entire solar range (specifically, ultraviolet, infrared and low or diffused light). Hence, much of the incident sunlight energy is wasted by solar modules, and they can give far higher efficiencies if illuminated with monochromatic light. Therefore, another design concept is to split the light into different wavelength ranges and direct the beams onto different cells tuned to those ranges.[citation needed] This has been projected to be capable of raising efficiency by 50%. Scientists from Spectrolab, a subsidiary of Boeing, have reported development of multijunction solar cells with an efficiency of more than 40%, a new world record for solar photovoltaic cells.[2] The Spectrolab scientists also predict that concentrator solar cells could achieve efficiencies of more than 45% or even 50% in the future, with theoretical efficiencies being about 58% in cells with more than three junctions.

Q:How to setup my home on Solar Panel?
good okorder.com lots of good ideas there
Q:How to build a small SOLAR PANEL that will light a 60 watt light bulb?
Making your own photovoltaic (solar electric) panel is a nontrivial matter if you want to get 60 watts out of it. If this is a science fair project, there are some possible paths that I'd suggest: ) Make your own cupric oxide panel. With just one square foot, you can harvest perhaps 0.5 mW in bright sun - enough to power a solar calculator; -or- 2) Buy a panel to light your 60 watt bulb. You could probably get away with a panel that is 6 square feet, but would use a car headlight as the lamp. If you wanted to light a regular household bulb, you would need electronics to step up the voltage, and you would lose a sizeable fraction of the energy just in the conversion. -or- 3) Buy broken solar cell pieces, or individual solar cells, and solder them together into your own panel. This is a LOT of trouble, and is a finicky process to get working and keep working. And it may not end up being cheaper than buying a ready-made panel. But you can claim that you made it! By the way, crystalline silicon panels are in the ballpark of 5% efficient, and a 3' x 3' one would produce in the neighborhood of 20 watts.
Q:cheapest solar panels sold on line?
If okorder.com/... , cost $75 each. I haven't personally tried that product, but the company has been around for a long time, and is not a fly-by-night. If it has to last, there are dozens of places online that will sell conventional sealed panels. Expect to pay $2.00 a watt on up nowadays.
Q:Which stores can you buy solar panels at?
This one.
Q:where will i find solar panel info for free?
there's a e book called hand-crafted potential that covers making photo voltaic cells and panels. some extra progressive libraries have it. in the different case its a visit to the OKorder save (which style of kills the finished loose deal). in case you meant warmth air panels or warm water panels then there are extremely some books interior the library that cover that subject. mom Earth information mag also has had many articles on both photo voltaic/electric powered and photo voltaic warmth panels. in the journey that your library consists of adult males mag and keeps decrease back subject matters of their stacks.
Q:anybody owns a house solar panel system does it really save you money on electricity?
There is this really cool book that i just bought and im actually starting to make a couple of things you go on this website and follow the link you wont regret it, i promise i'm saving literally hundreds
Q:How much does it cost a factory to make a solar panel?
First Solar recently announced that their costs to produce panels dropped below $ per watt. I don't know how much of that is accounting tricks. Of course, that doesn't mean that they would sell panels for that price - any capitalistic company is expected to drive the price up to what the market will bear. Crystalline silicon panel producers are coming in at about $2.50/watt right now for the best of them. But again, the selling price is what the market will bear.
Q:Solar panels and your opinion?
The payback is usually between about 5 and 5 years depending on how expensive electricity is in your area, the rebates available, and where you live (is it sunny most of the time?) Most people that get them don't do it for the investment - they do it to be energy responsible - but it's not a bad way to do both if you have the money to put into it. I personally just pay for the green energy option from my electricity provider. So I am buying power from solar and wind farms, and it cost about 0% more per month. I don't get the benefit of free power, but it comes with a smaller price tag initially, and I think when we all invest in these technologies, the price will improve over time, so energy costs will be lower in the future.
Q:Opinions on Solar Panels?
I have a boat in a sunny place and four 80 watt panels. These will run my fridge Tv and a few LED's. I still have to run my engine for hot water and washing machine. My Batteries only last a few years and are a real pain. I go on the mains when I can to get the batteries topped up. The panels are ok if there is nothing else, they are not the answer to the future of energy supply. There is also the moral aspect of the feed in tariff. For the rich to load their electricity bill onto the less well off is not acceptable and those panels on the roof tell all your neighbors that you are doing it. That will show a greedy selfish attitude. If they are any good why don't the power companies buy them and save buying coal?
Q:can you hand make a solar panel?
The idea is to hand assemble scrap solar cells that would otherwise be thrown out. At one point in time, very few people would want to do this so you could get the broken solar cells for free but now they sell them by the watt. It's still cheaper than a pre-fabricated solar panel but it's very labour intensive. Technically it's like wiring a bunch of batteries together, you measure the voltage and current a broken cell produces and decide whether or not to wire it in series or in parallel with other cells to get the performance characteristics that you want plus try to fit them onto some kind of structural panel in a fashion that uses the space efficiently. Since your handiwork is likely to be fragile, you'll probably have to put some plate glass on top to protect the cells from the elements, you can also improve performance by positioning fresnel lenses to increase the amount of light on active elements versus inactive areas of the panel.
