Characteristics of Polycrystalline Solar Panel

I Solar Cell : High efficiency crystalline solar cell. Even if under the weak light, the solar module can produce maximum power output.

II Tempered glass (toughened glass): Anti-reflecting coating and high transmission rate glass increase the power output and mechanical strength of solar module.

III EVA and TPT: Using high quality EVA and TPT to prevent destroying and water.

IV  AI frame: Without screw, corner connection. 6 holes on the frame can be installed easily.

V Junction box: Multi function junction box with water proof.

VI Long lifetime: ≥25 years; Less power decrease.

VII Good performance of preventing from atrocious weather such as wind and hails.

VIII Resisting moisture and etching effectively, not effected by geology. .

 

Standard Test Conditions of Polycrystalline Solar Panel

The opto-electrical specifications shown below are stabilized values being measured at Standard Test Conditions of multicrystalline silicon Solar Panel, Irradiance: 1000W/m2, Spectrum: AM1.5 at 25°C, The info below is subject to manufacturing tolerances. Where appropriate minutes of measurement are available and are used for the dimensioning of the installation.

Currently,We have 250w-300w solar panel stocks in Both West and East Coasts made in Vietnam,India,Korea,Malaysia and Japan.Meanwhile,we also arrange production line in Wisconsin,USA.If you're interested,please contact us soon.

Thanks for your time.

Q:Solar Panel experts...please help.?
Unfortunately, I can't give you a lot of specifics on what you should use. However, I can tell you that the very best system for you simply might not be available to you, in which case it really doesn't matter how good it is. Your best bet would be to talk to a supplier in your area and see what is available, THEN start looking at the differences between those. Unfortunately, solar panels aren't quite to the point of being a common-place product...yet. Another thing to consider would be how old your roof is. You might want to look into the possibility of building-integrated materials if you are in need of a new roof. Talking with somebody who sells the panels in your area will help you understand a lot more than just doing raw research. Get their take on it, then fact check and research what they tell you so you know you're not getting ripped off.
Q:can solar power panels installed at home provide enough electricity to power house hold appliances?
Yes, but people usually balk at the cost. Right now, the photoelectric materials are rather expensive. So, most people figure it is not worth spending thousands of dollars and will gladly pay hundreds of dollars a month to the electric company. Most estimates are that it takes at least a year and a half to two years to recover the cost of the panels by how much one can save on their electric bill. Most persons would rather pay out that money in little increments to the electric company instead of all at once when having their home built. Just a side note of trivia: The ability of certain materials to turn photons of light into electric current or the photoelectric effect is what Einstein was awarded his Nobel Prize for, not Relativity.
Q:how much is one solar panel?
no one has answered because you asked a question that cannot be answered. It is exactly the same question as how much is a car?. Do you want a passive solar heating panel, a solar electric panel, .5 Volts, ,000,000 BTUs, do you want just the panel or the panel installed and functioning, or what? the answer is between $5 and $5,000,000.
Q:A more efficient solar panel?
yes it is being done. i've seen adds for such a system. on the other hand, if you had a 5 sq in Lens focused on a small cell, and a 5 sq in cell, they'd be about the same. in fact, the cell might be a bit better because (A) there wouldn't be any loss in the Lens, and (B) it might be that the solar cell would use some frequencies to which the Lens was opaque. in addition, the cost of solar cells is dropping, making the cost of the mirrors or lenses uneconomical by comparison.
Q:is it feasible to create a solar panel that could harness more of the suns energy than what they can now?
we are near the edge of what is physically possible for solar power. You only get so many photons per area you know...and much of this is lost in entropy. Solar panels today are over 80% as efficient as what could ever be theoretically possible. No you will never get an easy solution to the land problem. lol what invisible talker suggests about using a black hole i suppose could be a way to increase the photons per area...but you would get much mroe power by using the tidal forces produced by a black hole than solar power heh...not to mention your panels will get sucked in...and whatever energy they produce wont be able to escape the black hole and power anything outside.
Q:Question about using solar panels......?
I don't think it is enough solar power. Your motor requires .5A x 9V = 3.5 watts. The solar cells are .450A x 4V x 2ea. = 3.6 watts, .2A x .5V = .3 watts, .A x 9V = .9 watts total solar = 4.8 watts. The problem with connecting the cells in series to get the right voltage, like the two 4V cells in series with the .5 volt cell (total 9.5 volts) is that the .5 volt cell limits the maximum current to only 0.2A. If you paralleled that with the 9V cell, you would get 9 volts at 0.2 + 0. = 0.3A, too low to operate the motor at its design current and voltage. The best you could do is put the two 4V cells in series, and in parallel with the 9V cell (a blocking diode might be a good idea, but probably not required for such a small array). That way you get 8 volts at 0.55 amps.
Q:Does infrared radition occur in solar panels?
- Radiation from the sun is mostly Ultra- Violet. - There are 2 types of solar panels, Solar thermal collectors and photovoltaic cells. - Put simply, photovoltaic cells take the UV rays and produce electricity. - Solar thermal collectors (which is probabl
Q:How much does it cost to put solar panels on a house? ?
There okorder.com/ Why pay thousands of dollars for solar energy ($27,000 average cost) when you can build your own solar panel system for just a fraction of the retail cost. You can build a single solar panel or you can build an entire array of panels to power your whole house. Some people are saving 50% on their power bill, some people are reducing their bill to nothing. But what’s most impressive is that just by following these instructions some are even making the power company pay them!
Q:Solar-Cell-panel help please?
I hope this will help you choose your charge controller / battery charger more effectively. Good luck!
Q:A good brand of solar panels for my house?
You don't say what you are doing. Are you trying to get electricity from them and need solar photovoltaic panels or are you trying to run a heating or hot water system and need solar thermal panels. It is unfortunate that both of these are known as solar panels as they are really two entirely different designs. Currently the solar thermal panels are more efficient and therefore have a quicker pay back period usually measured in lower single digit years while the photovoltaic panels have paybacks that are sometimes more than double that unless you figure in increased property values and state and federal subsidiaries and tax credits where available. Edit: Recent advances make any current investment in photovoltaic panels likely to be obsolete in 5 years. Still someone has to be on the cutting edge. Two currently available technologies are concentrating the sun's rays within the collector on a much small chip area.2 This improves the efficiency and lowers the cost as concentrators are cheaper than chips. The other option is newer chips that accept a wider spectrum of solar energy.3 This has the potential advantage of producing more energy on cloudy days. This may not be so important in your situation. Balanced against cutting edge technology will be the possibility of getting older panels at a less expensive cost. The bottem line will always be pay back period. More panels at a lower efficiency and cheaper price will be just as good as high efficiency at a higher price if the numbers work out. 4 Between two answers here you now have a criteria for selection and some recomendations. Good luck with your project.
