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. .

Q:Solar Panel Current=Battery Current+Load Current?
complex task. browse in google and yahoo. that could help!
Q:do solar panels have to be in direct sunlight?
PV panels do not have to be in direct sunlight. If they are behind glass they need to be well ventilated to remove excess heat. If PV cells connected in series are not uniformly illuminated the series will produce an amount of power that is based on the light on the least illuminated cell. Thus moving a panel back from a window will mean that for large parts of the day it will produce almost no power as parts of the panel are shaded. This applies only when the cells are connected in series. In parallel they suffer no special degradation of production, but just the sum of illuminated cells. This makes a difference when you decide to use a higher voltage panel... high voltage panels are more susceptible to partial shading. But connecting low voltage panels in series gives that same degradation. Stay away from placing a panel back away from the window, or close to the edges of the window, under roof overhangs, trees and surrounding building shade, where possible.
Q:kilowatt solar panel help?
Also you can look for INSOLATION TABLES on the Internet. Keep in mind, though, that the useful output of a solar system that produces AC will be somewhat less than the theoretical value. Local conditions, orientation of the modules, dust on modules, wire resistance losses and efficiency of inverters will drag down the true output. My 6 kW system produces just over 4 kW at optimum sun height.
Q:what is solar panel? full description needed?
Solar panels are devices that convert light into electricity. They are called solar panels because most of the time, the most powerful source of light available is the Sun, called Sol by astronomers. Some scientists call them photovoltaics which means, basically, light-electricity. A solar panel is a collection of solar cells. Lots of small solar cells spread over a large area can work together to provide enough power to be useful. The more light that hits a cell, the more electricity it produces, so spacecraft are usually designed with solar panels that can always be pointed at the Sun even as the rest of the body of the spacecraft moves around, much as a tank turret can be aimed independently of where the tank is going. DS's solar cells are even more efficient than regular solar panels made for satellites because they use solar concentrators.
Q:How to wire solar panels?
i'm involved approximately do-it yourselfers, i'm one, yet... Sorry to inform you, yet connecting image voltaic panels to grid capacity will require an electrician. there are a number of standards for specific disconnects to circumvent harm to the utillity corporation workers that would desire to be seen. you will additionally might desire to have an inverter sized to verify your panels. the straight forward answer is to connect your panels to something specific, without connecting it into your place wiring. An occasion is to connect your water properly pump to image voltaic capacity and disconnect it from the grid. yet you will nonetheless want an inverter and could might desire to calculate the capacity demands of the pump and the quantity of capacity available out of your panels, which varies via your longitude and variety. It sound like an straight forward element to do, yet without specific training and adventure you would be sorry in case you attempt this your self.
Q:Solar panel power question?
The specifications you give say the solar panel produces 5 watts at 2 volts (DC) so that isn't enough voltage to power an ordinary (20-volt) light bulb. You could get 0 of these panels and connect them in series so they put out a total of 20 volts and the total power available would be 50 watts. The panels would light the bulb that way, provided the bulb isn't over 50 watts and you can afford the panels. A panel does provide enough power for a 2-volt car light bulb less than 5 watts. However, the maximum current you can get from these panels is .25 amperes (5 watts divided by 2 volts = .25 A.) This isn't enough power to run your pump which takes 6.5 amperes - at 20 volts, that would be 780 watts. Another thing to check is the pump motor; many electric motors are designed to run on AC only and will be damaged if you try to run DC through them. Remember solar panels produce DC so the raw output from a panel will not work on an AC motor.
Q:Could you have a solar panel in space?
Absolutely. Many satellites and other spacecraft that have been launched throughout history carry solar panels to power themselves. The International Space Station alone has hundreds of square meters of solar panels. Transmitting the power from one place to another wirelessly is a bit more difficult, but not fundamentally impossible. So far we don't have any good technology to do it over long distances. But we're getting there. One proposed future source of power is 'solar power satellites', orbiting devices that would collect sunlight and turn it into a microwave laser that would be fired down to the Earth and collected in a giant dish kind of like a radio telescope. The idea is that this would be non-polluting, environmentally friendly, reliable, would help to boost investment in space technologies, and wouldn't take up the large amounts of land area required for traditional solar power. However, some people have argued that it is a bad idea on the basis that if the laser accidentally missed the dish, and came down in an inhabited area, it might cause human fatalities or damage to the environment or human artifacts.
Q:im trying to power up a cell phone and laptop with a solar panel.?
Oh, i could hate that!! i'm continually having to locate a marvelous sufficient spot to apply my photograph voltaic calculator, very stressful. Dimly lit would not keep it going. i could somewhat have a reliable, rechargeable battery. Now, photograph voltaic backup may be high quality. you will desire to touch Nokia and tell them approximately it. possibly they're going to call the telephone once you!
Q:What do i need to use a 2v solar panel to charge a 6v lead acid battery as i cant find a 2v to 6v regulator?
Yes, certainly. So long as the solar panel's voltage exceeds the voltage of the battery (which is probably going, certainly if it can be a discharged battery, which is lower than 2 volts), then it will recharge the battery. Additionally, a 2 V solar panel can produce bigger than 2 volts. Nevertheless, the rate of charging is more likely to be depdendent on the availabilty of daylight. And of course, the better the capcity of the battery, the longer it takes to cost.
Q:I have 700watts ups and 2V,65amp battary..i want to add solar panel to just only charge my 2v,65amp batt.?
What you are stating is that the battery you have will operate the UPS for about 2 hours before it is drained past the point of no return (technically 2.82 hours, but that would be a dead battery - most well-designed UPS systems cut off when the battery gets below about a 30% charge so that battery is not damaged. Lead-Acid batteries have about a 0%/month self-discharge rate if there is no load connected. The very best systems are as low as 3%, the worst are over 20% - and all at a 'normal' temperature. So, you will need a maintenance charger of about ten (0) watts or so - amp will be more than enough. And about any solar panel will handle that much with the proper charging connection.
