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:How do Solar Panels Work?
Solar panels are made of many solar cells.solar cell is an electicial device that comverts sun energy directly into electricity by the photovoltaic effect,which is an physic and chemical phenomenon.solar cells are usually connected in series in moodules,creating an additive voltage.
Q:its about solar panels?
It depends on what you want to do with the solar panels, Heat your water , heat a pool or spa, or to make electricity to use instead of that supplied by the power company. The first three are fairly easy and straight forward. Depending on the amount of water that needs to be heated, the location you live at in relation to the equator and the location of the solar panels and piping . The panels for this applicatin are 00s of feet of piping that absorbs heat from the sun and circlate it. The panels them selves are sort of inert and can be very heavy when filled with water.. Makeing usable power to replace the power company is a real problem because among other things solar cells create DC voltage. A house runs on AC voltage. So all of the items to heat water still apply, location, placement, etc. But now we have to figure hrs of sunlight the output of the cells running the power to a transformer to transform the voltage from 2 volts DC to 20 volts DC and then running the power thru a converter to change it from DC to AC at each point ( transformer converter ) there is a loss of power do to a change in current. After all of the above if a cloud comes by your power will stop, and at night you will have no power. The fix for that is storage cells AKA batteries which store the power until you need it, like night time. The glamor of a all solar powered home is great,, but it isn't practical. So What to do, You eliminate the battery storage, and also hooking up the power to your home. You feed it right into the power companys wiring and guess what? The electric meter on you house runs back wards your send more power to them during off peak times that your using. For every dollar the meter runs backward you get a free dollars worth when you need it. This is a way of storing the power as credit with the power company instead of batteries Its a lot to understand and I hope I helped
Q:What are the limits of solar panels?
I believe solar panels gather enough energy from the sun in the daytime.I don't own one therefore I AM not a 00% sure unless it runs on batteries,generator or alternator.Who knows it just may plug up at night.
Q:How many Solar Panels for my Pool?
I don't think heating a 70,000 gallon pool with solar panels is practical. My husband has designed and built our solar hot water system. It works quite well. We live in Arizona. There's no way we could heat that much water using sun energy. You have to heat the water and compete with the outside air.
Q:can I connect my pool pump to a solar panel?
What does the advertisement have to do with your question? Yes; BUT, depending on the pump, you may need several panels and possibly an inverter if it is an AC pump. You will ALSO need at least battery in the circuit to provide a load to the panel.
Q:Hey. I need some help with solar panels and batteries :) Please see the detailed version beneeth :)?
One lithium cell requires 4.2V to obtain its full charge, Never exceed 4.2V ! Output from solar panel if below 3.7V , nothing charge to lithium. Total charging time until the cell is full depending on the AH rate of cell and the charging current that solar panel can be provided. Suppose cell is rate 5AH, and the charging current from solar panel under full sun shine can maintain 0.5A ( use solar panel short circuit current rate from its specification as a reference ) , hence, 0 hours is enough. And be sure the solar panel can maintain 4.2V output at 0.5A . Remember, over charge lithium cell one time might reduce its life into half . Therefore, let the solar panel output passing through a precision regulator to maintain output is 4.2V is the best way, because, as cell reaches 4.2V , no more charging current is forced into cell ( automatic stop charging ). If you do not have the knowledge to make this simple variable voltage regulator with LM37K ( if you choose this way, buy solar panel output has at least 2V) , you may choose to do it manually by install a current meter and a variable resistor in series between the panel output to cell. By adjust the value of resistor, charging current can be controlled ( if you choose this way, buy solar panel output has as less as 6V ). Count the charging time with a clock and adjust the charging current from time to time to maintain 0.5A .
Q:Do solar panels effect birds and/or other animals?
mynameismud, you are hilarious. I cried i laughed so hard. Holy crap, how old are you?
Q:how do I become a solar panel contractor?
Contact some solar panel manufacturers or distributors. I recently started working for a solar panel dealer and they can't find enough qualified workers to install here in the US. Desperately seeking electricians but don't pay well.
Q:would the planet cool if covered in solar panels?
No, the top argument is that extra CO2 is inflicting the ambience to keep greater warmth from the sunlight. Having image voltaic panels might scale returned the quantity of CO2 interior the ambience we are putting in it real now via giving us an means source that doesn't emit CO2, and that's approximately it.
Q:Improvising Solar Panel Made from Old CD or DVD? Possible or not?
A solar electric panel? No. Solar electric cells, or more properly photovoltiac (PV) cells, are made from specially prepared (doped) wafers of silicon, much like transistors and diodes. CDs and DVDs are made from plastic plated with aluminum. They don't have anything to do with each other. Of course you can make a reflector out of CDs or DVDs, and you could use a bunch of them to focus sunlight on a water tank or something - this is called solar thermal generation. (That's what that ehow page is talking about, not generating electricity.) But there are much better things to use for mirrors.
