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: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 anyone give me some info on how to figure how many panels needed for a 0 volt 2 amp pool motor. Thanks/ Run 5 hours a day
- You okorder /
- Q:i also need to know how does a solar panel work
- When sun light reaches solar panels, it releases electrrons to make an electric current. They are made od silicon or germanium which has this property. Photons in the sun light when hit on semiconductor like silicon, releases electrons o make the current flow.
- Q:If a solar panel has a power rate of 80 Watts and efficiency of lets say 30%. Does that mean the maximum power this solar panel can generate is (30/00)*80=54 Watts or its just 80 Watts?
- Solar panels are tested in a lab that has a light the produces 000 watt/hrs per square meter. In these conditions your panel will produce 80 watt/hrs. If you would like to know what it does in really world conditions you have to find the sun-hours in your given area. A sun-hour is basically how many watt/hrs hit a square meter in a day. This number changes based on time of year, orientation, and temperature. Here in Fairbanks Alaska if the panel was at 90 degrees facing true south in October (.9 sun-hours) It would produce 80 X .9 X .8 (20% efficiency loss due to wires and controllers) it would produce 273.6 watt/hrs on average each day.
- Q:i have to do a science fair project and thought it would be cool to make a solar powered vw bus. i have 2 6volt solar panels to power a dc motor that works off of 9v 2v or 8v. i also bought a 2nd motor because the first wasnt workin for us. this one is a 3v motor. ive had them in the sun but they wont work. please help, thanks
- You didn't say how much power your panels can produce, or how much power (current x volts) the motors require. The panels must meet or exceed what the motor requires. You might need to get a very small motor and a little gearbox out of some other motorized toy, or at least a small pinion gear for the motor and a larger ring gear that can be attached to an axle (similar to how RC cars accomplish their drive train). A worm gear drive set might be even better if the motor / solar panel combination isn't very powerful - it'll go slowly, but some movement is better than no movement. If you put the panels in series, a 2 V motor should be the best match (again, only if its power requirements are small enough). If you want to try running the 3 volt motor off the panels, you might try paralleling them (make sure you get the polarity right or they'll try to kill each other) - you'll still be mis-matched, but if the motor requires less power than the 9/2/8 volt motor(s), it might work. If you have or can acquire a multi-meter, you'll be able to measure the voltages and currents and that will not only help you see what's going on, but adding some details might help others help you get this working.
- Q:Can solar panels be used for powering outdoor events or festivals?
- Yes, solar panels can definitely be used to power outdoor events or festivals. They are a sustainable and reliable source of energy that can provide electricity to run lights, sound systems, food stalls, charging stations, and other equipment needed for such events. Additionally, solar panels can be easily set up in open areas, making them ideal for powering outdoor gatherings without the need for grid electricity or noisy generators.
- Q:Can solar panels be installed on a shopping mall or retail center?
- Yes, solar panels can be installed on a shopping mall or retail center. In fact, many commercial properties are embracing solar energy as a way to reduce electricity costs and decrease their carbon footprint. Installing solar panels on a shopping mall or retail center can provide a sustainable and renewable source of energy while also promoting environmental responsibility. Additionally, it can serve as a visible demonstration of the property owner's commitment to clean energy and attract environmentally conscious customers.
- Q:Hi,I am thinking about getting solar panels installed. # I like to cut my electric bill. #2 I like to eliminate my oil boiler and use some sort of electric boiler.I use about 5000-30000 KW per hour( winter-summer). My oil bill is around 600 month winter time. Over all i pay around 4000 a year. My electric bil now is around 2000-2500 year. Is this possible? I live in NY. I heard you can get up to $35000 rebate from LIPA( Electric company) and 2k from federal and 5k from State( is the state or federal every year?, how does that work). Any help is appreciated.

Lots More Information 0. See all Physical Science articles You've most likely visible calculators that experience sun cells -- calculators that certainly not want batteries, and in a few instances do not also have an off button. As lengthy as you have got sufficient mild, they look to paintings eternally. You could have visible better sun panels -- on emergency street indicators or name containers, on buoys, even in parking plenty to energy lighting fixtures. Although those better panels are not as ordinary as sun powered calculators, they are in the market, and no longer that rough to identify if you recognize in which to appear. There are sun mobile arrays on satellites, in which they're used to energy the electric strategies. You have most likely additionally been listening to approximately the sun revolution for the final twenty years -- the inspiration that sooner or later we can all use loose electrical power from the solar. This is a seductive promise: On a brilliant, sunny day, the solar shines roughly a million,000 watts of vigour in step with rectangular meter of the planet's floor, and if we might accumulate all of that vigour we might simply energy our houses and places of work free of charge.
- Q:How many kilowatts? Would it be enough to power my electric heat?Does one panel cost about $2000.?
- I doubt it'd supply your heat. Anything involving electric heating uses tons of energy. Also, keep in mind that you don't just need a panel but also a DC to AC converter.
- Q:Rooftop solar panel (not sure if rubber or plastic?) has leak arising from thin vertical crack in panel about long. Any ideas for repair?Thanks.
- Depending on the material and operating temperature of the panel, it MAY be possible to fix it very simply and easily by applying Hot Glue Gun adhesive over the cracked area. The high temperature glue gun adhesive melts at approximately 60 degrees Farenheit, and if the collector temperature does not quite reach, or exceed that operating temperature, then that repair method should work. Another possibility is an aerosol spray can product called LeakEnder. This is usually available at your local hardware store, or the major home improvement centers [like Lowe's, Sutherland's, Home Depot, McCoy's, etc.]. After preparing the area to be patched by cleaning, you just spray the LeakEnder patching material on the crack and an eighth of an inch or so around. IF the operating pressure or the collector is very low, it MAY even be possible to patch the leak with nothing more than a narrow strip of DUCT TAPE!!!!! Another possibility, but unless carefully accomplished is to weld the crack with a Soldering Gun and some scrap plastic from packaging material. The problem with this fix is that you must be very experienced in application of heat from the Soldering Gun, OR you will melt a larger hole in the collector tube than the crack was. Regardless of patching method, it is CRITICAL that the cracked area to be patched MUST be CLEAN and DRY BEFORE applying any patching material. Good luck!
