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:Why do solar panels produce zero energy?
Hey Cosmic, forget about Wayfare and Jenny here, but I have to say your question is a bit vague. When you say the panels produce near zero, how near? Are you using a watt meter, ammeter, or some other sort of metering device. Solar electric, or photovoltiac panels are made almost entirely of silicone wafers. Same as computer chips, when they get hot, the resist the flow of electrons. This is why most panel manufacturers advise installers to upgauge wiring if the temperature falls below 40 degrees F (5C) regularly. Below 0 C, you have to upgauge 2 wire sizes. A good quality panel will put out 50% of its rated power in very cold climates, so it stands to reason that they will put out substantially less in hot weather. Many people think places like the SW United States is great for solar because it's always sunny. In Las Vegas for example, they have 27 sunny days a month, and in August, the temperature frequently reaches 50 degrees C (20F) so people with photovoltiac panels are not even getting half their rated power on a good day. I'm not sure this is what you are asking about. Our home has been powered by the wind and sun for 2 years now. In the summer in the upper midwest, the days are warmer of course, but also much longer than in the winter. So our batteries will frequently fill up by 2:00pm, and the charge controller will taper off the solar charging the rest of the day to minimize overcharging. If you were to check the meters at 3pm, you might notice only 3 or 4 amps coming in when the array is rated at 42. This is normal for us in July and August. These are some reason why a solar array produces near zero in the summertime. Take care Cosmic, Rudydoo
Q:How do home solar panels integrate into a houses current electricity?
The utility is your battery. Doesn't make any difference which is used first. At least that's the case in Calif. However, you need an electrician to do the attachment, and probably an inspection by the utility.
Q:How effective are solar panels?
Well, the maximum amount of energy you can receive with 00 percent efficiency is kilowatt per square meter. This is the energy that hits the Earth's surface. The best commercially available panels are 20-30 percent efficient. Cutting edge technology has gotten this percentage up to 50 percent, but you can't buy these for your home. If you're curious about efficiency, check out a panel's dimensions, find the area in square meters, and use that along with its Watts (divide by 000 to get kilowatts) to get your answer.
Q:Sizing solar PV panels?

Q:How many solar panels do I need?
I am a current solar panel professional worker. I suggest you try to obtain a 34RTS TurbibineIVX solar panel as it will cover all your energy needs.
Q:help setting up a solar panel system?
That okorder.com/... , but expect to pay several thousand dollars for something that actually works. If you just want to use the place for intermittent getaways, a generator may be sufficient, and you can skip the solar panels. If you intend to live in the place, then consider getting a system that is at least 500-000 watts of panels, and a 000 amp-hour or more battery bank.
Q:Why do solar panels stop working?
They really don't stop working unless there is some sort of manufacturers deficiency, where a connecting tab(wire) is broken. Generally their output just decreases over the years. There are plenty of solar panels over 40 years old still producing electricity, which is 0 years past the typical 30 year manufacturers waranty.
Q:What to do with a solar panel?
Hey AJ, Tom is quite right, a panel that size is a great trickle charger at .2 amps. If you have a good sized 2 volt battery, like from a truck, or for a boat trolling motor (it should be at least 60 amp hours) you can hook it to the battery and it will charge it slowly anytime the sun shines. Don't worry about the voltage, most 2 volt nominal volt panels are wired for 8 - 9 volts, and if you hook them to a battery, the panel voltage comes right down to the batteries charging curve voltage anyway, they are designed for that. What you do need is a diode. A diode is an electrical check valve, allowing current to flow in one direction, but not the other. This will prevent the battery from discharging through the panel at night. Many panels today come with diodes inside the junction box on the back of the panel. If yours does not have any, go to Radio Shack, look for a 6 amp silicone diode, usually around75 cents. Put it in series between the panel and the battery, then, while you have a voltmeter hooked to the battery, connect the panel/diode to the battery and see if the voltage goes up slightly. If it does, you're all set. If not, turn the diode around and try it again. It has to be connected into the circuit the correct direction. Many people will state that you need a charge controller, but this is not necessary if your panels max current, ISC is less than 2% of your batterys amp hour capacity. In your case, if you have a 60 AH or larger battery, skip the controller. There is a great discussion about this in Richard Perez's book, I will list it below. If you want to learn more about these devices, there is a great magazine that gets into the nuts and bolts of renewable energy, it's called Home Power Magazine, the link is below. We started by hooking a slightly larger panel to some golf cart batteries 2 years ago, reading that magazine and going to some energy fairs. Today our home is completely powered by the wind and sun. Check it out sometime. Take care, Rudydoo
Q:Powering my house with solar panels?
Homes vary tremendously in their usage. It will be a factor of 0: between a conservative house, and a heavy use one. To get the answer for your own house, check the electric bills. Also, the answer for the size of solar electric system varies with the location of the house. A Minnesota residence may get only 2/3 or /2 of what an ideal California house gets, even though both are sunny. As a data point, our California house has no air conditioning, no electric heat, no pool, and no big screen TV. We use maybe 5 - 8 kWh a day on average (more in winter, less in summer). We have a 3 kW solar array on the roof, and it roughly keeps up with our usage.
Q:I would like some info on Solar panels and Wind Generators...please?
The best sort of solar panel for $ to energy is the hot water type that use a vacuum tube system to heat your water. This saves you money on heating water and is relatively cheap to install compared to other things like wind or PV solar. I'm not too sure about where you live (I'm in the westcountry of the UK where wind energy IS viable... but usually it isn't). The best sort of Photo voltaic solar panel (that makes electricity)is still expensive yet very reliable as they only need photons to fall on them not neccessarily full sunshine and they are improving all the time. It depends on the pitch of your roof as to whether snow settles on them. One can have a system that sells power back to the national grid and then you buy what you need with a discount for what you produce. Obviously if you can afford enough panels one could even make a profit. Or you can go self-sufficient, but then you need batteries and an inverter to convert your 2 volt battery output back to 20 volts or whatever you use (it's 240 volts in the UK). Then it's a matter of how efficient your batteries are in amp hours. Dry mainainence free deep cycle batteries are best for this job and quite expensive still. Wind generators are only really practical if you can mount them high enough from the ground to where there is more constant wind. As I said that depends where you live and the prevailing winds. The very small ones are basically useless except for emergency lighting or something, so one needs a fairly large turbine to produce enough power for a modern home so planning restrictions should be considered when going down this road. For now, solar power is definitely the way to go, even as far North on this planet as Canada and the UK. Good luck. Once you have the system it's basically FREE energy!
