Solar cell module production process

Line called packaging line components, packaging is the production of solar cells a key step in the packaging process without a good, multi-well battery is also not a good component of production boards. Battery package not only the battery life is guaranteed, but also to enhance the combat strength of the battery. Product quality and high service life is to win can be the key to customer satisfaction, so the quality of components of the package board is very important.

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 does solar panels give power to the batteries?
solar panels work in an interesting way. light is absorbed by each solar cell, and light 'photons' bump into electrons to produce 'voltage'/power. the process is naturally called the 'photo-voltaic effect'. the loose electrons are captured by an electrical conductor in the solar cell (usually made of silicon) and a circuit is completed ... solar panels may generate more power than is actually needed. this extra power is simply stored in lead-acid batteries (they store upto 000 watts). read more about it here...
Q:What is a good type of solar panel to get for my house?
solar panels are VERY heavy and can be very complicated, youll need a professional. your roof may need to be reinforced to handle the weight added. some states like Arizona will pay for the system for you.you could use solar power to heat the water in the house and everything else off the power company. if you do, get one with a glycol heat transfer solution. they heat more efficiently.
Q:What is the main material for making solar panels?
If you make your own, in addition to buying silicon also need to buy for the packaging of silicon photovoltaic glass and EVA film.
Q:how efficient are flexible solar panels?
Up to now, it has very poor efficiency, about 5% to 23%.
Q:How to find amp for solar panel project?
It is possible your meter does not have the capacity to safely measure more than 300 milliamps which is too small to measure current output from solar panels. Assuming no losses in the system or components, if your meter does not have the capacity to measure 0 Amps, you will need to get one that does. Analogs are better than digitial for this. Most often the 0 Amp circuit of the meter has a discrete positive plug location for the positive test lead. Most have a common ground connection with the rest of the meter functions. If you are measuring current at the battery in the charge mode- Negative lead of meter goes to positive terminal of battery and positive lead of meter goes to the cable that was connected to the positive terminal of the battery. Since the Wattage is a nominal measurement, if you measure between the panel and controller, take measurement on one leg of the panel, as you want to measure the current with the loaded active circuit. Meter is oriented the same way as the measurement at the battery would be made above only this time the meter is between the panel and controller. At peak solar conditions, expect current to be measured at 2.5 to3 Amps or more per panel. Under optimal conditions your panel will have higher output than their ratings indicate. Open circuit can be close to 20 volts. Never short circuit the output of the solar panels. It is volts multiplied by amps that gives you Watts.
Q:solar panels on housing developments?
Solar Panels in housing developments is not being used because it would add $25,000 to $40,000 to the price of the home. Most people in the USA don't understand that after a few years the solar electric panels will start paying them back. It is not just the upfront cost. People would rather spend that 40K on somthing smart like a new corvette. Which has no pay back at all then something stupid like solar electric and helping themselfs or the rest of the world. So if the builders were to add them to the house people would just buy from another builder and the one adding the solar roof tops would just go broke. The State would have to find a way to credit the buyer or buider enough to make it worth it. Is it not more fun to spend millions on finding out where Anna Smith is going to be barried? Or maybe billions on top of billions on War? If we had spend the money on solar that we have spend on Iraq alone we could have put solar on every roof top in the whole USA and had few billion left over. Think about it.. 200 million people in the USA with three to a home would be 66 million homes. It would have only cost 528 billions dollars to put a kWh Solar Electric system on each house in America. But that would be stupid. War makes more money. We don't want Exxon to go broke do we?
Q:question about Solar Panels?
Assuming that you have / will upgrade wiring sizes to carry the extra wattage, that the new total wattage resulting from the addition doesn't overload any existing charge controller, diodes and / or inverter you have installed, then paralleling it straight into one of the other 2 volt groups should do nothing but add current to the system. True, it will be somewhat imbalanced, but it will work. Your other options would be to reconfigure everything down to it's native 2 V configuration which will raise current and lower voltage, with the additional panel creating the additional current to raise the wattage or to put it in series with the other 4 panel clusters so that you would get 36 V and additional current to account for the raised wattage. One last approach might be to set it up on another battery bank of it's own (small and at 2 V) to then connect to the same inverter. You'd be getting more power and storage capability that way, sort of a partial backup system, really, that will take some of the load off the other components to help extend their useful lives and get a bit more flexibility into it as well. The choice is yours here. That is all the ways that the system can be connected in, assuming everything in the first sentence checks out;-) It's difficult to make a recommendation without knowing what other components are in use and what the maximum ratings they carry are. Just remember that parallel connections add current and voltage stays the same, series connections add voltage and the current remains the same and you can figure out what to do with this thing to help you if you stay within maximum ratings for the charge controller, diodes and / or inverter involved. Good luck and stay safe!
Q:How to tie small solar panel system into my house's electircal system?
Not that simple. The N E C covers electrical systems and your state utility regulators cover what and how you can do it. As a practical consideration the inverter produces power and would have an outlet to tap it. Possibly a standard convenience outlet that is the same as your house devices. The problem is to provide a cord that does NOT have exposed hot conductors when it is plugged in and how do you isolate the system from the power grid. To do this you need both a reverse service device and transfer switch that will isolate the house from the grid while the inverter is operating.
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.
