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.

Q:kilowatt solar panel help?
You would be amazed how often I have answered this question. The answer is that it depends on your latitude and local weather . Let's see if I can give you enough information so that you can determine the answer for yourself. A kW solar panel is rated at kW when it is exposed to a solar flux of kW/m^2 (called a peak sun hour). There are readily available tables of effective peak sun hours per day by city (see Reference ). Let's use Fairbanks, AK as an example (it is the first line of the table). Fairbanks get an average of 3.99 of peak sun hours per day on average. So your panel would produce 3.99 kW*hr per day on average.
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:are flexible solar panels possible?
Of Coarse! In fact flexible solar panels have already been invented. Ever hear of a solar panel shirt? Instead of the standard crystalline silicon cell these new solar panels use a flexible polymorphous silicon cell to pull in power from the sun's rays. They can be placed on clothing, cell phones, and virtually anything else.
Q:How will i construct solar panel?
The key is like a spiral stair case with landings at each floor, but the momentum of having to turn is enough to climb from floor to floor. I guess the energetics use the handrail quite utterly and only, pressing against it like bearings in a wheel. With metals and metalloids a 3' x 3' solar panel would power your house and car and make your energy bill negative, but costs several million dollars since the chain of rare elements is only affordable to obtain by strip-mining top soil of many square miles of fertile land just for a single panel and thus destroys good farmland for hundreds if not thousands of years. Clearly solar panels will not solve any problems ever...unless their yours only.
Q:Question about Solar Power and Wind Power?
A 000 sq. foot abode isn't very great whilst it includes the standard length abode. at present the main inexpensive and best variety of eco-friendly potential for powering a house is wind potential. an outstanding wind turbine can get you on the brink of seventy 5% to a hundred% or much extra performance. extra beneficial potential produced via wind will reason the electrical powered meter to run backwards. At that factor, you're promoting the surplus electrical energy decrease back to the electrical powered company, providing you with extra money in the direction of a destiny electric bill. in spite of if image voltaic potential can help, image voltaic potential, in itself, might fee 2 to 5 cases extra beneficial than wind potential.

Q:how much do solar panels cost?
The silicon ones(last 5 to 25 years) run about $4-$5 a watt the amorphous (thin film) a little less (may last 5-0 years). If you use megawatt hour (000 kilowatt hr) a month you will need at least 3000 watts minimum. Therefore if your electric is .0 per kilowatt hr( $00 per month) the payback is around 25 years once you add the batteries plus inverters(batteries $50-$00 each)(synchronous inverter $3000 to$20000)(ie $5.00/.0=50 months at optimum output).Figure (depending where you live) probably only 50% so break even is usualy about 20 yrs.Ie you pay 20 years electric bill and hope nothing breaks(insurance not included) then you can start saveing money.
Q:Can you connect a solar panel to a regular plug, using copper wire?
NO NO you will cause a fire and lots of damage. Do not play with the power from a wall outlet. Outlets supply 20 or 240 volts AC Your solar panel supplies low voltage (perhaps 2 volts) DC. The two are totally incompatible. Speakers require no power, just the audio signal from a power (audio) amplifier. .
Q:Can I plug a solar panel into a wall socket to lower my electric bill?
You can use a solar panel to heat water, and you can generate electricity, but you can't plug it into a wall socket. The most effective way to save on your energy bill is by heating water. Solar panels that produce electricity, don't store it. They produce it for that particular time, and if you're not there to use it, it's gone. Furthermore, the electricity isn't always regular, it may have peaks and shortages. The best way to tap into that, would be to sell the electricity you produce to the grid, and then buy it back when you use it.
Q:How much do solar panels cost?
I have a coworker that did her home with a 5 kw system with batteries and whole house inverter. It cost $55k before the Florida $20k rebate. She sells back to the grid, but the system will not pay for itself for at least 20 years. It will not run the air conditioning, either. The batteries will give 3 days power for everything else without sun. There are companies trying to lease solar equipment, but none seem ready for prime time, yet. I've been to Sun-Electric (Venetian Causeway across from the Herald building) in Miami to buy surplus panels. They have a whole roof of panels and sell back to the grid, but they also have a room with batteries and an inverter and close shop at night.
