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:Are solar panels only effective in places where there is an abundance of sunlight?
Solar panels are *more* effective in places with abundant sunlight, but can be used anywhere that there is light. The problem is an economic one. Solar panels are expensive and can only produce so many watts per square meter. If you have less sunlight, you'll need more panels to get the same amount of power. Germany has a relatively high latitude, and are reported to make extensive use of solar panels (funny, I spent 2 weeks there last month and saw very few panels). The reason for their use of the panels is that their government offsets the cost of installing them through subsidies. Other governments have similar programs.
Q:What factors effect the amount of electricity produced from solar panels?
It depends on what you mean by amount of electricity. Normally that would mean the total energy produced over a given period. In that case, the main factors are ) Efficiency of the solar cells 2) Total irradiation received: incident radiation density times the solar panel area, and the angle of the incident radiation. Item ) is determined by the materials and method of construction of the solar cells Item 2) depends on the location of the panel, both on earth's surface (latitude), time of year, and how the panel is oriented with respect to the horizontal. Altitude of the location can also be a factor. Prevailing weather conditions, number of cloudy days, etc. are important. Independent of these parameters, larger area means more electricity.
Q:how much money can I make a year for the electricy I sell from a solar panel?
Ultimately it depends on your utility and the country you're in. In countries like Germany, Spain and the UK, the utilities will pay a higher price for the power you produce then what they sell it to you at. Otherwise, in countries that don't have such arrangements, net metering is best where what you produce is discounted from the amount you buy per month therefore so long as you produce less than you use, you get the full retail rate, otherwise you may get only half the retail rate with some utilities. Obviously, the solar panels are rated and won't produce much more than the rated power, a 4 foot by 2 foot panel would usually be rated at 00 watts but in most situations will produce about 80 watts and would probably cost about $500 US installed. If you assume 8 hours of usable sunshine a day, 70% sunny days, a 25 year service life, monthly billing and 0 cents a kilo watt hour retail rate, you can expect at most a -.67% per annum return on your investment, that's a negative sign out front. Basically without any subsidies, you will lose money on the panel, sure you're get some money every month, about $.34 per month for that 00 watt panel but it won't make back it's money at at a rate of 0.0 per kwh. With subsidies it might be a good investment but it's still not a good deal without subsidies.
Q:Can I join 5 or more solar panels into line to the battery bank. I don,t have a regulator connected, just st?
You can do this, but it isn't the best way to go. There is no problem with joining the solar panels. There are two ways to do this, in series and in parallel. A series combination will add the voltages that each panel is producing together, but not the amperages. For example, if five panels are producing 6V at 300mA each, the end result will be 30V at 300mA for a series array. A parallel combination combines the amperages of all the panels, but not the voltages. So, in our earlier example, five panels at 6V and 300mA would provide 6V and 500mA (.5A) if wired in parallel. Series-parallel combinations are also possible, giving some of the benefits of each method. This would probably better understood by doing a quick search on Google Images for series, parallel, and series-parallel. You CAN connect the solar panels directly to your battery bank with no regulator. Unfortunately, without a regulator, the connection is two-way. When the sun is out and the solar panels are producing more voltage than the batteries, the batteries will charge. However, when the panels are producing less voltage than the batteries, the batteries will instead send power into the solar panels, which will be dissipated and wasted. The panels may charge your batteries during the day, but they will discharge them at night.
Q:Why don't we use solar panels?
It's expensive - solar power isn't competitive with power from the grid in most countries and it's a very expensive in terms of capital - you have to put most of the money up front. Meanwhile fossil fuel plants are cheaper to build and from then on you only spend money on fuel when you're selling power (and of course you don't have to pay for the damage you cause society with air pollution and greenhouse gases).
Q:How efficient are the solar panels....?
Commercial monocrystalline panels are typically 8% efficient but inverters can be 65% to 90% efficient and lead acid batteries are 50% efficient at charging and 92% efficient at discharging plus they self-discharge at 3% to 20% per month.
Q:Solar Panels in Abu Dhabi, UAE?
I know where in Dubai , just go to Naif road where they sell the satellite equipment , there are a couple of shops that sell all kind of solar panels and dish equipment stuff. Sorry can't remember the name, But it is right in front of the paid parking lot (the private not public one).
The sun produces energy. When that sunlight hits most surfaces, it causes that surface to heat up. When the sunlight hits some other surfaces, instead of heat, the result reaction is electricity charges. Some of those surfaces are certain types of silicon, which is what solar panels are made of. The electricity produced is DC electricity. It is then funneled to charge a battery, where it can be stored. If need be, it is passed through a inverter, which changes it to the AC power that we use for our appliances.
Q:How many wind turbines and solar panels does the world need to replace coal, oil and nuclear power?
Green technology at this stage is not viable for the long run...we don't have the technology as of yet to replace all other modes of energy...Windmill Farms are EXTREMELY ugly and kills thousands of birds and only work when the wind is actually is not ready for prime time, too expensive for the average joe...we should be pursuing other engines that would use less gasoline and some exist but nobody is promoting those because they are convinced electric cars are the way to go but those are a farce because we don't generate enough electricity now for homes to use, can you imagine how little we would have if all cars starting using that same energy? IT is a farce that during an economic crisis the current powers that be are wasting money on green technology garbage that won't work. We should be figuring out how to drill our own oil and get off foreign sources and build more plants to produce more electricity, not figure out how to use the little electricity we currently produce in all our vehicles...Liberals...what a concept.
Q:solar panel for computer?
Most decent laptops can use 50W of power or you'd actually need a large solar panel with good sunlight. I just looked up how big a 50W solar panel's about 64x64 centimeters...which is very big and expensive! So, solar power may not be the best solution to power, or charge a laptop battery. Maybe there are some solar powered chargers that charge the battery very slowly, but probably not.
