product description



Strings of series cells are usually handled independently and not connected in parallel, though as of 2014)individual power boxes are often supplied for each module, and are connected in parallel. Although modules can be interconnected to create an array with the desired peak DC voltage and loading current capacity, using independent MPPTs (maximum power point trackers) is preferable. Otherwise, shunt diodes can reduce shadowing power loss in arrays with series/parallel connected cells.[citation needed]Multiple solar cells in an integrated group, all oriented in one plane, constitute a solar photovoltaic panel or solar photovoltaic module. Photovoltaic modules often have a sheet of glass on the sun-facing side, allowing light to pass while protecting the semiconductor wafers. Solar cells are usually connected in series and parallel circuits or series in modules, creating an additive voltage. Connecting cells in parallel yields a higher current; however, problems such as shadow effects can shut down the weaker (less illuminated) parallel string (a number of series 

The photovoltaic effect was experimentally demonstrated first by French physicist Edmond Becquerel. In 1839, at age 19, he built the world's first photovoltaic cell in his father's laboratory. Willoughby Smith first described the "Effect of Light on Selenium during the passage of an Electric Current" in a 20 February 1873 issue of Nature. In 1883 Charles Fritts built the first solid statephotovoltaic cell by coating the semiconductor selenium with a thin layer of gold to form the junctions; the device was only around 1% efficient.

Q:How are solar panels developed and distributed in America?
The first link below is one of the best sites for recent news about solar panels. You should be able to find stories about solar panels under development today. A little bit of the history: Solar panels have been around for about 50 years now. They were first used to power spacecraft. Solar power for domestic use started to develop rapidly in the 970's during the first oil crisis, but as energy prices fell in the 980's solar development slowed. Most of the large solar panel makers were purchased by large oil companies who seemed not to be too interested in solar. In the late 990's as concerns about both Peak Oil and Global Warming grew there was renewed interest in solar power and a number of new companies were started to develop new kinds of solar panels. Many of these new companies have grown larger than the older solar companies still owned by big oil companies. Over the last 7 years or so growth in the solar market has been explosive with a compound growth rate of almost 40% per year. In 2005 the solar industry for the first time started to consume more silicon than all other electronic industries combined resulting in a world wide silicon shortage that is still with use. New silicon refineries are coming on line and the shortage is expected to diminish by 2008 or 2009. Check out the two links below. They will help you a lot.
Q:Solar panel connectionI
You should probably ask this in the electronics section.
Q:are biological solar panels possible?
No, there are organisms like that for instance coral, but in order for them to give us energy we would need to fuse are DNA with theirs
Q:Do you know that China is the largest producer of solar panels in the world?
Solar voltaic panels are not 30,000 dollars each, a good panel, 24.4Vmp, times 95 watts, is about 900 dollars. Solar electric generation, makes sense, not because of the myth that the energy transmission companies 'buy' the energy you produce in excess (energy companies, zero out the balance at the end of the year, so that it only makes sense to design a system that equals your needs, not exceeds them). Solar electrical generation, is the future of energy freedom, but the powers that be, do not have yours' and my economic freedom in their portfolio. They are actively pursuing the globalization, to push down the working class, to the 'post industrial age', where the working classes, can once again, be relegated to serfdom, while the super rich, drink DOM, and watch us toil in the sun.
Q:Are our scientists making solar panels all wrong??
There are two basic types of solar panels. ) Thermal absorbers 2) Photovoltaics Thermal absorbers are black in order to convert sunlight to thermal (heat) energy. The whole idea is to capture all of the light with a dark surface, convert it to thermal energy and transfer the energy into your home for water heating or space heating. If you make the surface white or reflective, then the surface will absorb only a small fraction of the available light, hence the efficiency will be very low. In other words, the panel will not produce any heat. Photovoltaic panels produce electricity instead of heat energy. Photovoltaic panels are made from thin slices (“waffers”) of silicon with special coatings on the front and back surface. One of these coatings on the front is an antireflection coating to capture the light and channel it toward the silicon. Underneath the antireflection coating the silicon waffer is coated with other chemicals that convert the sunlight to electricity. The combination of these coatings gives the panel a dark color, usually blue or black. Here's the bottom line. If you want thermal heat or electricity from solar panels, the panels have to capture the light. When that light is captured, the surface appears dark because no light (or very little) light is reflected back to our eyes. It is not possible for a surface to be an efficient absorber, capturing all available light, and at the same time appear white or bright color or reflective to our eyes.
Q:How many Solar panels?
If you have 480 volts, it might be 3-phase, and not a simple matter of multiplying volts and amps. However, that's in the ballpark of 25 kW, very doable for solar. That's on the high end of a residential installation, but very small for an institutional installation. What will influence the size of the array more is where you are geographically (that is, how much sun you get), and how often the motor runs (that is, how much energy in kWh does it use per day)? 480 volts is nothing to be trifled with. You should really get a power engineer to architect your system.
Q:Solar panel experiment ?
Acciona of Spain is actively conducting research in all sorts of alternative energy. I understand they have an experimental solar farm someplace in the desert southwest of the U.S. that is made up of 283,000 panels. I don't know the size of the panels or anything else about the project other than that. 50 years ago it would have been the U.S. conducting leading research in solar energy-especially in the U.S. Southwest.
Q:Are solar panels actually efficient?
They're more efficient than nothing, or fusion for that matter since fusion hasn't gone anywhere in the last 30 years. Since most energy is used during the day time when its light out solar panels will do pretty well. In most habbital places on the planet its light out for a good part of the day while wind doesn't blow steadily in most places.
Q:Does making solar panels cause more pollution than they take away when used?
The amount of energy needed to extract the raw materials from the Earth exceeds the amount the finished PV panels produce.Processing the materals takes additional energy.After manufacturing they have to be transported.Photovoltaic panels only generate </2 volt per square inch in bright sunlight.They become less efficient when they get dirty.
Q:Making solar panels bad for the environment?
Sure your proper, sunlight panels (photovoltics) could be used to make electricity for small electronics. Proper now sun cells are on many calculators, and even flashlight. However the trouble is the lenght of time the cells take to charge the gadget, verses the vigour demand. I don;t consider the scale of the panels, and the period of time needed to charge the device are sensible. One think i've been thinking is that all should have a photovoltaic panel to charge a battery. Then, use the battery to cost phone telephones, MP3 palyers. The panel and the battery would be in regards to the 8 x eleven inches, and could sit down in window, or on a dash board to get charged, then utilized in doorways over night to charge contraptions.
