4). Bulk supply: With the production capacity of 500MW, we can produce large quantity every month. This can satisfy most customer requirement.

 

3.Usage and Applications of Poly Cells

Solar cells are often electrically connected and encapsulated as a module.

Photovoltaic modules often have a sheet of glass on the front (sun up) side, allowing light to pass while protecting the semiconductor wafers from abrasion and impact due to wind-driven debris, rain, hail, etc. Solar cells are also usually connected in series in modules, creating an additive voltage.

Connecting cells in parallel will yield a higher current;our solar cells have passed IEC Certification.

With high quality and stable quality. Our Cells can greatly improve the performance of Solar Modules.

Q:H2 as an Alternative Fuel Source using Solar Panels?
It's a great idea, but there are problems. The first is that hydrogen is very difficult to control; it is a small molecule, and very slippery. It is difficult to handle from that perspective; Teflon tape and other common plumbing techniques just don't cut it. Secondly, once you have the hydrogen, you'd have to compress it in order to put it into a cylinder of some sort. This takes electrical power, and in turn is wasteful. Compressed hydrogen storage has is own risks, including hydrogen embrittlement, and the peculiar nature of hydrogen (including having an invisible flame, and a remarkably wide flammable range) makes it quite dangerous. After all, relatively safe products such as propane gas and butane lighters- well-established and very common- are surprisingly dangerous, causing injuries and fatalities each year. In order for something that is more dangerous (hydrogen) to come to market as being a hydrolysis product, either the products will have to be home-made (and therefore more dangerous), or very expensive.
Q:kilowatt solar panel help?
Also you can look for INSOLATION TABLES on the Internet. Keep in mind, though, that the useful output of a solar system that produces AC will be somewhat less than the theoretical value. Local conditions, orientation of the modules, dust on modules, wire resistance losses and efficiency of inverters will drag down the true output. My 6 kW system produces just over 4 kW at optimum sun height.
Q:Are solar panels a viable option in IL?
Absolutely you can have solar panels in IL, there Anna. I am from Rochester, NY so I am a little familiar with frequent snowfalls! Plus my In Laws have solar panels and they live just outside of Chicago. (Oak Park sounds familiar, but I cant for the life of me remember the name of their community) Check with your local building department as to what you may have to do to your existing roof, as the panels and its necessary roof bracing can be quite heavy. Add a good Lake Michigan snowfall to an already heavy roof and you could have yourself a big problem! In better news many utilities and states around the country provide financial subsidies and incentives that along with the subsidies from those from the Federal Government greatly reduce the initial cost and speed up the amount of time it takes for you to recoup your initial investment. Solar panels by their very nature are warm, as they absorb the light from the sun. The latitude for IL is such that the solar panels on your roof will be tilted so much that the only way snow can build up is if there such a snowfall on your roof that its accumulation rises above the solar panels. There is no such thing as heated solar panels and you can very easily have solar panels in climates ranging from the Carribean to Northern Canada/Alaska. If you get serious about solar energy give a company called Sun Electronics a call. I know it may sound lame but my in-laws used them for their house and have been quite happy with the outcome. My In laws (at times) are cheap and are not an easy crowd to please.....but again are very happy with their outcome! Good Luck.
Q:2V Solar panel directly to 2V inverter...and restult.?
An 300W inverter will draw 25 amps from a car battery but the solar panel will only produce about 4 amps. By drawing too much power with the inverter you lowered the voltage so much in the panels wiring that the amp rating on the internal wiring was exceeded and they melted. Next, time run the panel to a voltage regulator, then the regulator to a car battery, then the battery to the inverter.
Q:Should I buy solar panels?
Without doing any calculations, I would assume that paying down debt would be a better use of your money. Solar panels are only going to get less expensive and more efficient with time so waiting before you invest in solar panels is a good idea. Of course, to properly evaluate the prospects of going solar, you should consider the tax credits available in your state and the promotional value to your business.
Q:2 Questions on Solar Panels?
Solar panels come in many kinds, using a variety of technologies and sizes, but the most common is still the crystalline silicon type. The power produced is variable, but the better ones you can buy approach 20% efficiency, and the peak energy from the sun is 200W/m^2 (Watts per square meter). This only occurs when the panel is lined up with the sun on a clear day with the sun high in the sky. The efficiency is also affected by how the electrical energy is taken from the panel, and the temperature of the panel. In the full sun the temperature approaches 60C, so the voltage drops. The links below provide a lot of information about such matters. A BP panel 50mm x 674mm gives a peak power of 20W. This is .07 square meters. As you can see this is very close to 20%. (The third link). However this is less in practice because the sun may not be full sun and may not be perpendicular to the panel. The output drops as the cosine of the angle to the sun, more or less. Even with peak sun this would produce only about 00W charging a 2V battery directly, unless an electronic Maximum Power Point Tracking (MPPT) charge control is used.
Q:Do solar panels make electricity from light intensity or watts?
DIY okorder.com
Q:would the planet cool if covered in solar panels?
The opposite - they heat the Earth up. The ground underneath might be brown or green or sand. The solar panels are Black. They absorb more radiant energy. Solar electricity is energy and somewhere down the wire will produce heat. Solar's saving grace is that it has the same heating effect year after year. But greenhouse gasses have a cumulative effect. The excess gasses produced in year one are added to the gasses in year two, etc. For instance say the heating of soalr cells is 5 times (5s) that of greenhouse gasses (g). Year - Total Heating - 5s + g 2 - 5s + 2g 3 - 5s + 3g 4 - 5s + 4g 5 - 5s + 5g 6 - 5s + 6g 7 - 5s + 7g 8 - 5s + 8g 9 - 5s + 9g 0 - 5s + 0g etc... In 50 years you have 50 - 5s + 50g
Q:Is heat a factor in how much energy is gained when using solar panels?
no only the sunlight is used in generating electricity
