FAQ:

1Have you ever sold your products to companies in my country?

Of course, we have customers in all general PV markets, but I think we should expand our market share along with the market growth.

2When did your company set up?  You are a new company, how can I believe your quality?

We entered into Solar PV industry in 2005, now we have several plants in manufacturing of a-Si and c-Si panels, and our capacity is 220MW per year. Till now we have already passed all the tests by authorized laboratories, e.g. TUV, VDE, UL.

Q:solar panel design question?
Because we and the trees are trying to solve a different problem. We want electricity, a tree wants light (and some heat) for photosynthesis. In getting the electricity we use Silicon for solar panels. (Sometimes Gallium Arsenide). And we exploit the same thing in Silicon that allows them to be computer chips. The fact that they conduct differently when voltage is applied. But for a solar panel that is done essentially in reverse. We GET a voltage difference (electricity) from shoving energy through it. Look up junction bias on google or yahoo for explanation. But the DESIGN problem is: You have to couple these panels together the right way - according to their bias. You can't string them up willy nilly. There is a pattern. And when one breaks in this pattern. (I mean when the actual panel cracks, which they do easily as they are brittle). It can change the overall bias. This can make even be worse than if it was removed, it can actually fight against the working ones. The efficiency is there in arranging them like a tree, but the practicality of maintenance would be daunting.
Q:_How many solar panels needed to light up a whole house?
It's not really the solar panels that power the house, they charge a battery bank and there's an inverter that jumps the battery power up to household current level. If you start getting into more expensive systems, they can sense when the batteries are full and start diverting power into the local electric grid. Some places the electric company is required to pay you for generating current, other places tell you tough luck. I suggest looking on OKorder or something at some of the home solar kits on sale there and look at how large a house they are rated for to get an idea of how big a system you're going to need. I don't know if you have access to the power bill history of the house you're getting in Dubai, but the power company there might be able to provide you with a history of average kW hours the house consumes. A 2400 sqft house with a gas stove and a gas water heater and wood heat is going to consume far less electricity than a house with all electric appliances and the consumption history of an individual house should reflect that so you can buy appropriately.
Q:What solar panels are the most efficient?
There are a lot of solar panels available today's. The problem of the efficiency is the proccess of converting, these cells use the photons of the sun to react with the ( Si compound inside the cell) due to the little thing that cell's are only a fraction of these energy is converted, remember that solar cells are paper thin and the really problem of these cells are the voltage not the amps. A single 3x6 inches solar cells can produce 3.6 amps but only 0.5 volts.
Q:how do solar photovoltaic panels work?
Hey E Girl, photovoltiac panels are pretty simple. They start with a solid block of silicone, and shave thin layers off of them, called wafers. Once you have about 72 of them, you take half of them and dope them with boron, then the other half are doped with phosphorous. Once that's done, they take one each phosphorous and boron wafer, and glue them together with a special conductive epoxy glue, and attach a wire to each wafer. When the two glued wafers are exposed to the sun, a reaction occurs that forces free electrons from the silicone particles from one wafer onto the other, and a voltage is generated between them, about /2 volt to be exact. Once all 36 pairs are glued together, they are wired in series, connecting the phosphourous wafer from one to the boron wafer on the next, and so on. If you start with 72 wafers, you'll have 36 pairs glued together when you are done. At /2 volt each, that makes a 8 volt panel, which is used to charge a 2 volt battery. The charging source always has to have a few more volts than the battery. These 36 pairs of cells are then arranged on some kind of back board, glued down, covered with acrylic glass and mounted in a frame. There are some great websites you can go to for more info, I will list some below. Did you know that there are over 00,000 homes and businesses in the US alone that use some level of solar power to operate their electrical systems? That's good news. We actually live in one of those homes, it is powered by both the wind and sun and heated with solar and wood. I hope this answers your question, good luck, and take care, Rudydoo

Q:Solar Panel Installation?
Wires from panels go to controller input terminals. Controller DC battery terminals to battery so that the controller will protect batteries and split power as required by demand to the inverter. Output DC on controller to inverter. Output AC or outlets on the inverter to AC appliances. One thousand watts is not very much capacity. It will keep your computer running and a lamp to read by. It won't run major appliances. A hair dryer is typically 500 watts and could not be run by this system.
Q:How does a solar panel work?
The term solar panel is best applied to a flat solar thermal collector, such as a solar hot water or air panel used to heat water, air, or otherwise collect solar thermal energy. But 'solar panel' may also refer to a photovoltaic module which is an assembly of solar cells used to generate electricity. In all cases, the panels are typically flat, and are available in various heights and widths.
Q:Can I power up 2Watt bulb using 2Watt solar panel power?
. Practically no. You have to account for startup current, and losses in the system. Ideally you would size your solar planel to provide the power you need to charge batteries in the day, for your needs at night. 2. Watts=Volts times Amps Really you just need to match the load and supply for volts, and make sure the supply has enough capacity to run your load. Current will take care of itself., in that the load will take what it needs to do its work. 3. It will bring the voltage down, causing the light to be dimmer.
