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:Solar Panel questions...?
all of the people on this site only care about pv. how about solar thermal? do you realize one of the most revolutionary solar thermal companies in the world has its headquarters in dorchester, ontario?(just outside london). its a simple way to eliminate your domestic hot water. works well in ontario, thousands of installs for domestic hot water per year happen in toronto by this company.....Enerworks.
Q:Solar Panel Batteries?
Sorry, I can't really help you :[ Google some stuff, look for help from people who know what to use. If I were you, I'd go with the lead-acid battery.

Q:Where do I find solar panels?
How much it costs, and whether it is worth it, really depends on where you live, and how much power you use. A very conservative house like ours, in an ideal area, could get by with a system that costs $5000 to $7500 net after incentives like tax credits. A house that uses a lot of energy, like a massive one with air conditioning, could need an array costing ten times that much. The only way to even get close on an estimate is to call a local solar installer for a quote. If there are no local solar installers, that's a clue that your area may not be very good for solar. Consider solar hot water also. That's generally cheaper and pays back faster than solar electric.
Q:How to build a small SOLAR PANEL that will light a 60 watt light bulb?
I don't have any practical experience building solar panel arrays to power a given device, but allow me to make this observation. Solar cells, when exposed to sunlight, will each generate a given amount of power (watts), and by wiring these in series, you will increase the wattage. Now, a panel three feet square will give you a certain amount of power, provided all the cells are wired correctly in series, and it may not provide enough juice to light the bulb. You can work around this by adding a step-up transformer (which takes the incoming power and boosts it to the desired level for output, with no moving parts). Voila! You've illuminated your bulb. I will admit, though, you'll have to do some math to determine what you need. A search on the Web will help you find the formulae and other information you'll require. Good luck.
Q:How to select solar panel for this application?
First, you need to make sure that your battery can take a regular 34Ah discharge without damage. The usual wisdom when using deep cycle lead-acid batteries is to allow for no greater than 50% discharge. This is to prevent the battery from ageing prematurely. Note that automotive batteries are not usually considered suitable for deep-cycle applications. Best allow for at least 200Ah capacity. Your solar panel capacity needs to take into account that whatever the nameplate output of the panel, that will be what it will produce under ideal conditions, actual output will always be less, often quite a bit less. You also need to allow capacity to cope with dull, overcast days when the light level is very low. You can get solar maps that will give you the sunshine hours and irradiation levels at your location. The solar panel capacity ends up being a juggling act between available funds/space and how critical it is that the light always works as desired. Let's say you had a 400W panel, which sounds quite generous. In the middle of winter, it may produce only 75W for 5 hours on a dull day, not quite enough to run the light for 0 hours. Would you expect several such days in a row? How many days could a 00Ah of battery capacity cover under these conditions?
Q:The voltage and power problems of solar panels
Because the MPPT controller has a wider input voltage range, it can also convert multiple voltages into current charge and better protect the battery.
Q:will a 5v 52watt solar panel charge four 2c dv 55ah batteries?
OK your math on the solar panel looks correct, but you are missing some critical information. What is the load on your batteries and for how long is this load being applied. Calculate the amp-hour load to see if your solar panel can recharge your batteries with the amount of sun light available. A safe engineering standard is to have twice as much capability as required. If you have a 200 amp load for 7.5 minutes, this would be a 25 amp-hour discharge and will take your solar panel over 7 hours to recharge your batteries. Your solar panel can easily charge the batteries up to full capacity with out any load on the batteries, if the batteries are 50% discharged, this will take about 32 hours. CAUTION! I am assuming that you are hooking the batteries up in a parallel connection, that will give you over 200 amps of current. You should charge each battery up to full charge before you connect them together, if they are not at the same exact voltage when you connect them together, they will self adjust so that each battery is at the same voltage level, at 55 amps this could be a very large spark. Each cell, there are six (6) cells in a 2 volt battery, should be at 2.7 to 2.2 volts DC per cell at full charge. Make sure your battery has a voltage 3.02 to 3.26 volts open circuit or no load. This should be full charge if your batteries do not have this voltage level, say one battery is at 0 volts DC, it could have a dead or shorted cell. DO NOT use this battery until you can get it to hold a 3.02 to 3.26 volt DC level.
