Product Description:

 

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. 

 

GENERAL INFORMATION

The installation of PV modules requires a great degree of skill and should only be performed by a qualified licensed professional, including licensed contractors and licensed electricians. Please be aware that there is a serious risk of various types of injury occurring during the installation including the risk of electric shock. All CUSTOMER modules are equipped with a permanently attached junction terminal box that will accept variety of wiring applications or with a special cable assembly for ease of installation, and they do not require assembly.

Q:its about solar panels?
solar panels are device that convert sun energy into electric energy by physic and chemical effect.solar panels price is high,but you will save your late electricity bill,it is cost effictive.
Q:How do you use solar panels?
Custom solar-heating systems are unique. Does yours have a circulating pump? Does it have a storage tank? Is the fluid that goes to the panels separated from the household water and transfers heat through a heat-exchanger radiator, and the fluid has antifreeze in it? If it does, is the antifreeze of the variety that won't poison your family if there is a leak? Does your system have a thermostat-controlled pump that turns on when the water in the panels are hot? Does it have a limit-thermostat to turn off the pump when water in the storage tank is hot? There are many more variations to operation of solar-heating panels. Find out who designed it or who knows how to operate it and ask them.
Q:can you hand make a solar panel?
The idea is to hand assemble scrap solar cells that would otherwise be thrown out. At one point in time, very few people would want to do this so you could get the broken solar cells for free but now they sell them by the watt. It's still cheaper than a pre-fabricated solar panel but it's very labour intensive. Technically it's like wiring a bunch of batteries together, you measure the voltage and current a broken cell produces and decide whether or not to wire it in series or in parallel with other cells to get the performance characteristics that you want plus try to fit them onto some kind of structural panel in a fashion that uses the space efficiently. Since your handiwork is likely to be fragile, you'll probably have to put some plate glass on top to protect the cells from the elements, you can also improve performance by positioning fresnel lenses to increase the amount of light on active elements versus inactive areas of the panel.
Q:Can you make a solar panel shift sideways?
having solar panels move like that on a mobile platform is inadvisable -- especially if there is a dynamic wind load resulting from the motion of the mobile platform. Even having a tilt mechanism is dubious at best. think of what limited marginal gain would be gained by mounting a small solar panel on the moon roof of a car. (ultimately, the best answer is to turn the car so that it's angle to the sun is optimal -- but the road/travel direction constraints are what ultimately prohibit that.) while there are ways to build sliding panels, the weight constraints would interfere with your weight/thrust ratios to the point of futility. if you really need that panel somewhere else, don't slide it out of the way, just buy another panel and mount it there. it's more expensive, but it's actually the cheapest solution in terms of design on a mobile platform.
Q:What is the most efficient solar panel?
Of okorder.com/... , and shop the web for the best panels for yourself. p.s. I'd avoid amorphous silicon panels. They may be cheap, but they'll go bad or seriously degrade in just a few years. p.p.s. I'd also avoid internet guides that claim you can make your own panels very cheaply, if you'll just pay them $$ for the information. Those guides don't live up to their advertising.
Q:Solar Panel HELP?
The only way it pays off is if your energy supplier or state refunds half or more of the cost. Even then, could take 20 years or more to pay off depending on your electrical usage. Most people are either misguided or doing it to reduce their carbon footprint.
Q:is it worth it to install solar panels?
In the state of Pennsylvania in the USA, a very basic 5KW solar installation will cost you $35,000. Of that you will recover approximately $28,000 over the next five (5) years between the State and the Feds. Making your net-cost something between $7,000 and $9,000 depending on various factors. All other things being equal in a standard household with fuel-based heat and window units vs. central AC, this system will provide roughly 50% of power required with a payback of approximately eight (8) years (with electricity at $0.4/kwh). The system has an estimated forty (40) year service life. Without _all_ the subsidies, the payback is longer than the estimated system life, especially if you consider the time-value of money. The life-cycle cost of a photo-voltaic array is horrendous. By that, I mean the total cost of producing the panels, installing them, and then removing them and disposing of them in an environmentally correct manner. All that added in and there is a negative payback. So, it all depends on what one defines as worth it. Putting the cost onto taxpayers via governmental subsidy to make an otherwise wretchedly expensive process viable may give you all sorts of warm-and-fuzzy feelings about renewable resources and reducing dependence on foreign oil and so forth. But the reality is that the true cost of solar panels exceeds that of nuclear power per KW delivered. Even today when nuclear plants start in the Billions-with-a-B in any currency you would care to name.
Q:What do you know about solar panels?
Solar power is produced by collecting sunlight and converting it into electricity. This is done by using solar panels, which are large flat panels made up of many individual solar cells. Using solar panels is a great way to generate clean and renewable electricity to power equipment or even the average home
Q:Solar Panel Batteries?

Q:Do solar panels add to global warming?
Third Law of Thermodynamics (in normal speak): “Not only can you never get ahead, you can’t even break even.” This is a truism that applies to all activities involving energy exchange (and almost everything else as well). Energy in the form of solar radiation falls on the earth. That energy is absorbed by the planet (everything) and heat results. Some portion of that energy is lost in the absorption process and the net released as heat is less than that absorbed from the sun. This is true in all cases. Solar panels, both photovoltaic and heat collectors are subject to the Third Law and they all lose some of the radiant energy striking them in the process of converting that energy into either hot water (or whatever fluid) or electrical energy. Regardless of the process there is always a net loss of energy. The time delay you mention has no bearing on the total heat gain or loss for the planet. In fact the “solar panel effect” reduces the net energy put back into the ecosystem because it introduces another iteration of energy loss through conversion. The Holy Grail of energy conservation it the ability to use, store or recover the entire amount of energy produced regardless of the source of that energy, burning hydrocarbons, geothermal heat exchange, solar radiation, mice on treadmills …..all forms of energy suffer a net loss in any exchange! If we could avoid that loss we could dramatically reduce the heat lost into the atmosphere or ground water and our net energy gain would also be dramatic! Check out the super cooled circuits in use to reduce resistance in sophisticated electronic equipment for a good example of the energy savings. (Of course the savings do not account for energy lost in the cooling process. In any event NO….. solar panels do not contribute to global warming via their operation. (Their manufacture is another story altogether!)
