Solar Module Introduction

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.

Electrical connections are made in series to achieve a desired output voltage and/or in parallel to provide a desired current capability. The conducting wires that take the current off the modules may contain silver, copper or other non-magnetic conductive transition metals. The cells must be connected electrically to one another and to the rest of the system. Externally, popular terrestrial usage photovoltaic modules use MC3 (older) or MC4 connectors to facilitate easy weatherproof connections to the rest of the system.

Q:How do solar panels work?
light from the sun hits the atoms and excites the electrons. This knocks the electrons out of the atom and then the electrons travel in a certain direction. This is the basics of electricity... flowing electrons. And so there's your direct current. I'm sure you could find out more by googling how do solar panels work
Q:A question about central a/c and roof solar panels?
Don't do it! It takes years to get your money back. Your better to put the money into insulation and or buying geo thermal unit. I knew someone who install solar panels on his roof to generate hydro and he didn't notice much of a change on his hydro bill and then he had roof problems . Central air units in last 2 years have become very efficient . Almost half the hydro of ones 0 years ago. If you can afford buy a geo thermal unit. It uses the heat of the ground in the winter 2 heat your house during the winter and the coolness of the ground to cool your house. They aren't cheap though. If you plan on living in your house for more than 0 years and have the room in the yard to install then go for it. No how you slice it though AC units use way more hydro than solar panels can produce. You would need about half a football field with a huge battery storage system to run a AC unit. When a company states you might on hydro I would stay away. Also remember they do not tell you about the costs of the upkeep on the solar panels and converter and batteries
Q:Any recommendation for best solar panels?
I have 3 ARCO solar panels and a wind generator on the Boat and it's all I need to live comfortably on 2 volts.
Q:Need help with Solar Panels (FAQ's and opinions)?
Also crystalline silicon, but almost triple the power. I would suggest that you have a lot more research to do before just buying a panel. A single panel like that isn't immediately useful unless you have a device that takes exactly that voltage, and is not critical. A solar water pump might fall into that category. For anything else, you would need additional equipment, such as a battery, charger, and inverter. Even at these prices, a single panel is unlikely to save you money over the electric company in the long run, unless your electricity is very expensive. There is economy of scale, so larger systems can and do save money, at least for people located in the right place. If you have a remote cabin where there is no electric company, then this could be worth it.
Q:how the power output of solar panels fitted to a house can charge?
Solar panels do NOT get charged, so the question is junk, or you misstated it. Solar panels are used to charge a battery bank, which stores energy for times when there is no sun. Then energy from the batteries is used, via an inverter, to power appliances in the house. OR do you mean how the power output of solar panels can CHANGE? In that case, they change when the sun moves, such as behind a cloud, or just changes angle in the sky, or goes out.
Q:You place four identical solar panels in 4 places.?
Well, as always, context is important. Sunlight is composed of a lot of different types and wavelengths of energy, and our atmosphere and magnetoshpere filter out a certain amount. If the question is actually which solar panel would produce the most energy (which I assume it is), we would have to look at how solar panels work. There are three different classes of solar panel function. Photovoltaic cells convert sunlight directly into electrical energy, but most systems are pretty low on efficiency. Solar cells can be used for generating heat, through boiling water or some other liquid frequently. And solar panels can be used to produce chemical reactions, breaking down solutions into ions, for example, and the breaking of the molecular bonds releases a certain amount of energy. So theoretically, the two sides of the moon get the same amount of solar energy, just at different times -- about 6 months of the year or so. If the solar panels were thermal energy panels, the ones on the Earth would do much better, because the moon is so much colder. The weather is the most convincing argument for comparing the Sahara and New England. New England is likely to be more cloudy and polluted than the Sahara. Since the Earth probably eclipses the moon a bit more often than the reverse, there may be a little more visible sunlight that gets to earthly solar panels, but the ones on the moon would get a greater proportion of the sunlight (more wavelengths, for example), so it would be close. The Earth eclipses only the near face of the moon, so that would give the far side of the moon a slight edge perhaps. I'd guess it would be the far-side lunar one, but too many variables to be sure.
Q:selling solar panels online - a good idea?
It's that offering installation that is the problem. Do you have the ability to arrange contractors to install where ever the customer may be? The online store model works best on a drop ship model where once you've shipped the parcel, you're done. Online selling of solar panels would be basically to the DIY crowd and as you've said, most people don't have the skills nor the enthusiasm to install them. The current price per watt installed is about $0 a watt. $ per watt are the organic dye and film solar panels which are horrendously inefficient and require much more square footage and that $ per watt price is before installation. Currently solar depends a lot on government subsidies to be worthwhile. The various green energy technologies (both solar and wind) lack the economics to be anything other than greenwashing and often if you consider the total impact to the environment, they are often worse than fossil fuels and even if the environmental impact of their manufacture is neglected, it's hard to compete with fossil fuels where nature has done all the work of storing solar energy in a convenient hydrocarbon form. Of course, there's still money to be made off people's ignorance. You've already asked this question several times, apparently you're not satisfied with any answers that are counter to your hopes. Why don't you try it and see how far you'll get.
Q:solar panel question?
Depending on the type of solar panel, any where from 6% to 42.8%.
Q:solar panel help needed ?
One square meter of solar panels can produce up to 50 watts of maintenance-free power for up to thirty years. The most common solar panels are for 2 V applications. For sq meter: I = P/V = 50/2 = 2.5 A A single solar cell always produces a voltage of approximately 0.5 volts, regardless of its size. For higher voltages, you have to connect individual cells in series to add their voltages. The larger the solar cell, the greater the current will be. You can also connect cells in parallel to increase current. Hope this helps!
Q:explanation of solar panels?
It depends upon your product. If it is a solar panel, I want to know if it is a photovoltaic panel or a thermal panel. If you don't know enough to know the difference for your question it might be somewhat difficult to suggest others should buy them. Products have to be marketed to a need either already felt or not so apparent. Photovoltaic panels supply an electric need and will offset electrical usage or may supply the grid if there is excess power. A discussion of payback periods including property values will be needed in any event. Thermal panels supply heat and hot water. They are more efficient than photovoltaic panels and will give faster payback times. (are cheaper) If you are a bit more specific more information may be possible.
