Product Description:

About us
We are a high-tech group wich specializes in solar products design,research, manufacture, sales,solar projects design

and installation.

Our national sales service covers seven parts, including northeast, north, east, middle, south, northwest and

southwest, international sales covers five continents and over forty countries, including Germany, Italy, Spain,

France, America and Brazil etc.

Our present annual capacity is 6 million for wafer, 60MWp for solar cells,200MWp for solar modules and one hundred

thousand for solar applications. It is expected that the annual capacity of 2012 will be up to 30 million for wafer,

300MWp for solar cells, 1000MW for solar modules and 2 million for solar applications.

 

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.  

 

Process is as follows:  

1, the battery test

2, positive Welding - Inspection –

3, on the back of cascading - Inspection –

4, laying (glass cleaning, material cutting, glass pre-processing, laying) –

5, laminating –

6, to flash ( to the side, cleaning) –

7, fitted border (glue, loading angle keys, punching, install box, scrub I glue) –

8, the welding junction box –

9, high-pressure test –

10, component testing -- -

11 appearance inspection, packaging and storage;

Q:Anybody install solar panels themselves?
i have always been interested in it but the storage (batteries) and power grid tie in (to get paid for excess) technicalities made me shy away. since your getting it installed im sure labor is a huge part of that -OKorder has tons of the equipment. I think wind may be a good home renewable source depending on where you live (cheaper than solar if you got the wind and space) I would doubly check any goverment offerings - I know they used to and maybe still do offer sizable credits if you are within the bureacratic standards so make sure the installers work with you on that. good luck -its new - and going to be a hassle to get right but the world needs more like you. willing to pay more now for a better tommorow (and not just $ wise) you should come out ahead as interest rates and market provides little value on that cash and saving any equipment falure you sound good. does the price include the batteries for all your produce kwh's? panels and labor aside batteries are the next big one
Q:Questions about Solar Panels and Battery back ups.?
Q:Why do solar panels burn out?
could be temperature, poor design and U-V damage If they are outdoor lamps like mine it is more likely the rechargeable batterys are bad.
Q:H2 as an Alternative Fuel Source using Solar Panels?
Currently solar panels are rated at about 5 percent efficiency. That means that about 85 percent of the solar energy that is falling on it, is wasted. Electrolysis is also about 67 percent efficient. So the TOTAL amount of solar energy you would have converted into hydrogen is 67 percent of 5 percent. Using my calculator that comes out to: about 0 percent total efficiency. About 90 percent of your solar energy gets wasted in the process. A better alternative to solar panels would be solar powered sterling generators. Sterling engines are EXTERNAL COMBUSTION engines, like the old fashioned steam engine, and can be run off any heat source - including the sun. Heat from the sun is focused using parabolic mirrors, and the efficiency of a sterling engine / generator combination is rated at about 30 percent. Your TOTAL efficiency - both solar sterling and electrolysis combined - would be around 20 percent. If you are dead set on using hydrogen? Even though there are better alternatives? Such as alcohol? Then I would suggest storing it in titanium dioxide pellets. This way you can store the hydrogen, without it being in danger of exploding. You can ALSO ram a hydrogen container like this into a solid brick wall. Once again? Without fear of an explosion. Numerous studies have been conducted on this. As for controlling the exact measurements? Nothing in the air-fuel ratio of a car - - or the timing - which you are also going to have to change - needs to be exact. A good enough approximation will do. As for how you get your measurements? You need to compare the density of gasoline vapor with hydrogen gas. A comparison of the molecular weight of gasoline - - as compared to the molecular weight of hydrogen - should get you started in the right direction for this.
Q:Will a 3w Solar Panel Charge A 55ah Car Battery?
Quite a while. I am assuming you are using 2 volts as your buss power. The small panels were intended as a float charge for batteries to keep them from discharging over a period of time. 3 Watts means only /4 Amp. Normally when I do slow charging of batteries, I am using right around amp, and that takes about a week to bring up a battery that was discharged past 80 percent capacity. When you factor in losses from corrosion, battery self discharge, and loose connections, you will likely want to add more panels. using your 55Amp/hour battery, a amp charger running constant in a perfect world would take 55 hours. Real world, probably closer to 64 to 72 hours. That for simplicity is 5 Watts constant charge power. Now you are using /5 of that with your current setup. so 5 times longer, whichh puts you in the 300 hour range of real world, or 220 hours of perfect world. This time of year, you may have about 8 hours worth of charging light, which puts you at close to a month. Don't fret. If you are using it for lighting in a shed, Power LEDs and tethering some of the inexpensive LED lights to the 2 volt source will give you plenty of light for a very long time, the panels will help some, but you will likely need to put the batteries on a charger, or you can build a gas powered 2 volt generator easily enough. Charge it up only when needed.
Q:What are the main components of a solar panel?
The basic components in home solar heating systems include: Collectors to take the heat from the sun and pass it to a fluid The heat transfer fluid which takes the heat from the collector for use or storage Heat exchangers to transfer the heat from the fluid to a home’s domestic water. Pumps to move the fluid through the collector and/or the exchanger, and sometimes to move the domestic water through the other side of the exchanger. Controllers to run the pumps when there is collector heat available.
Q:where to face solar panels?
Not compass south, but solar south. It's easy to find. Google Find Solar south and you can get directions. Even better are trackers, that will let your panels track the sun all day.
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:how would you build a solar panel?
i'd go to the solar panel store and buy one. It would be /0 the cost of trying to build one in my HOME shop.
Q:Advantages and Disadvantages of using solar panels?
Solar energy is a renewable energy resource and there are no fuel costs. No harmful polluting gases are produced. Disadvantages Solar cells are expensive and inefficient, so the cost of their electricity is high. Solar panels may only produce very hot water in very sunny climates, and in cooler areas may need to be supplemented with a conventional boiler. Although warm water can be produced even on cloudy days, neither solar cells nor solar panels work at night.
