1. What's brand of this solar panel?

Answer : Soular solar. We are the manufacturer of this panel, OEM service is available, wholesales is welcome.

2. We need your pricelist for all the models ?

Answer : we dont present "pricelist" for a new customers, Because different order quantity, different  quality grade has different pricelist; right now, we can produce  solar panel from 3w to 300w for both poly & mono panel.

Attn. : You can just inform us your "target price" and detailed requirement , we will evaluate if we can produce for you.

3 . Our common questions for the new customer's inquiry :

(1) How many pcs solar panel do you need ?

(2) Which type do you need, Poly or Mono ?

(3) What is your requirement on the power, Voc, Isc, Vm, Im ?

(4) Which transportation way will you select ? by air ? by Sea ?

Q:how does solar panels work?
Solar panels collect solar radiation from the sun and actively convert that energy to electricity. Solar panels are comprised of several individual solar cells. These solar cells function similarly to large semiconductors and utilize a large-area p-n junction diode. When the solar cells are exposed to sunlight, the p-n junction diodes convert the energy from sunlight into usable electrical energy. The energy generated from photons striking the surface of the solar panel allows electrons to be knocked out of their orbits and released, and electric fields in the solar cells pull these free electrons in a directional current, from which metal contacts in the solar cell can generate electricity. The more solar cells in a solar panel and the higher the quality of the solar cells, the more total electrical output the solar panel can produce. The conversion of sunlight to usable electrical energy has been dubbed the Photovoltaic Effect. The photovoltaic effect arises from the properties of the p-n junction diode, as such there are no moving parts in a solar panel.
Q:What Size Solar Panel Would I Need?
It sounds like saving money is your chief goal. If your house is not already super-insulated, that should be the first target. Super-insulation, radiant barriers, double-pane windows, white roof, weatherstripping, attic fan. Number two would be conservation. Can you turn the A/C up to 80? I visited a place in Wyoming when it was 0 outside, and 80 felt very pleasant. Third, efficiency. Have you considered a ground-sourced heat pump? Deep down below your house the water table may be colder than 40 degrees F, and can provide good cooling. After all that, you can look into solar electric, which may or may not be a good deal in your area. The type of solar electric that is most cost efficient is the kind that connects right to the house wiring and works alongside the normal electric company. You can talk with a local installer and get a free financial analysis. Then you can look at it and see if the installer is on the level, or trying to play accounting tricks with unreasonable assumptions. Solar makes sense in most parts of California, but Illinois is not known as a big solar area. The kits you have have seen were probably for standalone solar, generally an expensive proposition for the amount of power you get. Put another way, either it will be low power, or it will be very expensive.

Q:can i use 00 ohm /4 watt resister for 5v coming direct from solar panel?
Just connect the 5 volts out of the panel directly to the iphone via an USB connector. BUT, is the panel output always 5 volts, ±0.25 volts? Because that is the USB specification, and anything outside of those values could damage your iphone. And solar panels are known for their wide swings in voltage. Bottom line, resistor not needed, and you need to be positive you supply the correct voltage to the iphone. Best way to do that is to start with a solar panel that puts out at least 7 volts and use a LM7805 regulator. The only resistors needed are those to tie the data lines into a certain combination of resistance and voltage so that the iphone is fooled into thinking that a proper USB is connected. That would NOT involve a 00 ohm resistor. Search online for the proper values and connections. edit: are you repeating your same inane question with a different account? That is totally against the rules and could get you suspended.
Q:how much do solar panel batteries cost?
Kirraina is right the only ingredient i'm able to upload is purchase the ideal, as quickly as. in case you purchase 2nd or 0.33 ideal it is not long till you need to purchase it lower back. something I study a protracted time in the past, and it nonetheless is sensible as we talk- do you comprehend why the wealthy are wealthy? they simply yet something as quickly as! EG. a stable refrigerator will final 30 years, slightly bit junk 5-6 years. a stable refrigerator isn't 5 X greater funds than the main inexpensive one. subsequently that's the ideal deal?there is another attention, new technologies, attempt and discover something that is unquestionably upgradeable. playstation overlook approximately automobile batteries they are no longer outfitted for image voltaic platforms. you need to use ideal deep charging batteries. Sorry, definite they are costly besides.
Q:Solar panel question?
i agree with Liz but have a diffrent point i think u have not calculated for the roof mounted solar panels i am giving youy a bsic understanding hope that will help you Roof Mounted solar power systems consist of solar panels held in place by racks or frames which are attached to roof based mounting supports. Roof based mounting supports include: Pole mounts which are attached directly to the roof structure and may use additional rails for attaching the panel racking or frames. Ballasted footing mounts such as concrete or steel bases that use weight to secure the panel system in position and do not require through penetration. This mounting method allows for decommisison or relocation of solar panel systems with no impact on the roof structure.
Q:installing solar panels on roof?
Biggest problem is availability of sunshine in the UK. Do you get enough to warrant the fuss or financial layout? Another problem is the orientation of your roof. Facing directly south, with a slope (in degrees) equal to your longitude would be ideal. As far as electricity goes, you have to be tied into the grid to take care of the times you are not generating all the power you need. When you are generating more than you need, you sell it but get paid at the rate the utility normally pays, a lot less than you would pay to buy from them. Still, it's something.
Q:Does infrared radition occur in solar panels?
Solar panels do heat up. But that's because the radiant energy from the Sun that lies within the infrared (IR) band of energy causes the material in the panels to heat up. And that's the same for any body that has the Sun shine on it. Your face, for example, will heat up while you get a nice tan on the beach. That's due to the heat producing IR radiant energy. Now if those solar panels are supposed to heat buildings etc., that heat produced in the panels when the IR strikes them will be transferred, usually by some fluid, to floors of the rooms to be heated. And as the amount of heat generated by the Sun is proportional to the area of the solar panels, bigger areas of panel will generate more heat than smaller areas. Photoelectric solar panels are another kind. Here the interest is in the visible band of radiant energy from the Sun. Heat, from IR, is still there, but it is not the product sought by PE solar panels. The visible light photons knock off loosely bound electrons from the photoelectric material (typically silicon based) and those electrons are siphoned off as current. That's where the electrical power comes from for buildings using PE solar panels to provide their own electricity.
Q:Solar Panel Batteries?
Sorry, I can't really help you :[ Google some stuff, look for help from people who know what to use. If I were you, I'd go with the lead-acid battery.
Q:New Prius; Solar panles a good design?
The solar panels run the fan to remove hot air from the car. They do about the same amount of cooling that cracking the windows and using a heatshield over the windshield--that is they keep the interior of the car about the same as the exterior without draining the 2V battery. One problem I have with the solar panels is that they come with a moonroof. The other problem I have with them is that to get them you have to give up the additional safety features because Toyota won't put both the high tech safety features and the solar panels on the same car. So is it a good design? Well, nothing with a sun/moonroof is a good design IMHO, but that's the power of advertising for you. In that it runs a fan without draining the 2V battery, yes that part's good. Having to give up the high tech safety features to get it makes it a non-starter for me (and I live where it gets plenty hot so I could really use the fan).
