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.

Q:Which is Better: DIY Solar Panel vs commercial grade solar panel?
They can be if you are well educated and skilled in their assembly and working functionality, provided you obtain the same high quality grade cells and do proper assembly. Chances are good however that your first several may be just a little below par until you really get the hang of it and become well practiced just as the professionals are. Does take a considerable amount of grunt work however so figure if this is best use of your time or if you'd do better to earn at your regular work and pay a professional to do that which they do best.
Q:How much electricity does a solar panel generate?
This question was answered a few days ago. The Watt is the unit of of power, not the unit of energy. Energy is measured in Watt-Hours or Joules but not in Watts per unit time --- see the difference --- [] a Watt per hour v. [2] a Watt for an hour? The term, Watt per hour does not make any sense --- it is a bit like saying my car has 00 Horse Power per mile. You are right to say that the round figure for the power input of a solar panel is ,000 Watts per square metre, in the middle of the day when the sky is clear. Were the sun to shine for 0 hours per day in the summer, you could get as much as 7kWatt-Hours per day --- if you were very lucky. The roof area of a small house is no less then 50 square metres and this is more than big enough to supply all of you household energy needs but taking account of rainy days and taking account of the need to store the energy for night-time is an expensive problem, to satisfactorily overcome.
Q:Solar Panel/Energy help?
The rating of a solar panel is a maximum continuous rating. A 200 Watt panel will give a maximum of 200 watts under ideal conditions. A computer and monitor use about 400 Watts. not per hour - watts is Volts * Amps and a measure of Power. In hour a computer and monitor uses 400 Watt hours (Wh). Wh is a measure of Energy. To power a lab of 0 computers you will need 0* 400 = 4000 Watts. To run this from solar panels through the day only you would need a 4000 Watt panel. Except - its cloudy, the sun is in the wrong place - many factors reduce the output. To be reasonably safe you would need about a 2000 Watt panel. Then you would need batteries to store power through dull periods AND a voltage converter to change from low voltage DC from the solar panels to the mains voltage for your computers.
Q:know about solar panels?
Solar panels, often connected to other panels to form an array will produce electricity when exposed to the sun. At this time solar panel is one of the fastest growing business in the world. Given the fact that most of our energy comes from fossil fuels (Oil, Natural Gas and Coal) and that those resources are getting used up and more expensive to get to, and given the fact that solar panels are getting cheaper and more efficient, eventually, the electricity produced by solar panels (or photovoltaic panels as they are sometime called, PV for short) will be cheaper than that of CO2 spewing electrical plants. Actually, it could be argued that if the coal, natural gas and oil industry was not subsidized so much by our governments, and if you demanded that the process of producing electricity from those sourced be as clean as PV, PV would be a cheaper source of electricity than fossil fuel already. Make sure to also look into the solar panels that produce hot water. SHW (Solar Hot Water) is very developed in country such as Israel, where the law demands that all new house be build with SHW systems. Those panels are very efficient at capturing the heat of the sun and produce hot water much cheaper over their life than using gas or electricity.
Q:Why did the voltage of a solar panel drop significantly after putting it through a step down voltage regulator?
you cannot treat the open circuit voltage of a solar panel like a voltage source (like a battery.) the load response of the panel doesn't behave that way. small panels and panels that are producing less than about .5A are very happy to have their output voltage pulled down to whatever they're connected to (typically zero.) I observed the same phenomenon when i connected a 2V 725mA panel to a 2V 325mA fan -- the open circuit voltage of 5V dropped to 3V when connected to the fan, and returned to 5V when disconnected. The easiest workaround is to use 2V of rechargable batteries in parallel with the panel so that the battery holds the 2V potential difference and the panel just supplies the current. any excess current charges the batteries, so you might consider whether or not you need some type of charge controller to prevent burning the batteries via overcharging. there are actually very few applications of solar panels connected directly to circuits that i have seen that have any kind of robust performance -- if they work at all, they eventually die/burn themselves out in a couple of months. the best robust designs always have a rechargable battery and charge controller somewhere in the power circuitry to buffer the load circuit from the panel. .
Q:what can i do with a calculator solar panel?
take a look at the back of the psp, most rechargeable things have technical specifications for what kind of charger to use, like the voltage, the amps, and the wiring
Q:How many watt solar panel do I need to charge a 2v battery that wont be using much electricity?
batteries are rated with the help of the CCA, chilly cranking Amps the better the CCa the longer it is going to very last, don,t imagine you want a charge Controller as your consistently drawing juice from it, the picture voltaic panel will keep the bat at its height , then even as the solar is down , the pump will draw off the bat,
Q:Should we subsidize solar panels?
Recent investments into solar panels have brought about a couple of interesting realizations and developments. One, as you state, is that traditional solar panels (silicon crystalline panels) are not currently cost effective, even will full-scale manufacturing production. It's possible that improved manufacturing techniques will bring the retail price down somewhat, but it needs to be brought down a lot to make economic sense without incentives. The other, though, is that a new method of producing solar panels - thin film technologies - has been developed. These are currently quite expensive, but because there are no crystals to grow, they are expected to drop significantly in price as production increases. I believe that this technological development has been made as a direct result of government support for solar energy. It is not taking money away from research - rather it is providing the incentive for research. I could be wrong. I've been wrong before. But I think that these new solar technologies, which are already hitting the market, will dramatically change the economics of solar energy.
