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:solar panel design question?
Because we and the trees are trying to solve a different problem. We want electricity, a tree wants light (and some heat) for photosynthesis. In getting the electricity we use Silicon for solar panels. (Sometimes Gallium Arsenide). And we exploit the same thing in Silicon that allows them to be computer chips. The fact that they conduct differently when voltage is applied. But for a solar panel that is done essentially in reverse. We GET a voltage difference (electricity) from shoving energy through it. Look up junction bias on google or yahoo for explanation. But the DESIGN problem is: You have to couple these panels together the right way - according to their bias. You can't string them up willy nilly. There is a pattern. And when one breaks in this pattern. (I mean when the actual panel cracks, which they do easily as they are brittle). It can change the overall bias. This can make even be worse than if it was removed, it can actually fight against the working ones. The efficiency is there in arranging them like a tree, but the practicality of maintenance would be daunting.
Q:Solar Panel Wiring in SERIES?
If the panels are the same, there is no problem in putting them in series. If you examine the panels, they will be made up of about 36 identical cells in series. Ok, now you have 72 cells in series, fine if they are the same. You need (at a minimum) a diode in the line so that when it is dark, the panels do not draw current out the batteries (it wont be much but you might as well block it). You say the panels are rated 5 amps? Those are pretty good sized panels! Unless you have a charging regulator, I guarantee that they Will overcharge the batteries (unless the batteries are huge, like the size of a refrigerator). Did you maybe mean 5 watts? About a foot square? If so, the output is about 300mA (0.3 amps) which will not overcharge a battery as long as it is at least as large as a garden tractor battery. At a 300mA charge rate, it will take a longgg time to recharge.
Q:Solar Energy - What would these solar panels power?
A solar panel that is rated at 60 watts would produce that amount under the most favorable conditions of direct sunlight at noon in a good location. This would taper off to nothing at the beginning and ends of the daylight. A 60 watt Panel operating at full output for hour would produce 60 watt hours. If we assumed a straight line of output from zero to 60 watts and back to 0 again over 6 hours the average output would be 30 watts x 6 hours = 80 watt hours / day x 365 days = 65700 watt hours in a year / 2 = 5475 watt hours in a month. You lose about 0% converting from DC to AC. This reduces this to about 4927.5 watt hours. Your bill is measured in KW hr which are 000 times bigger. This is 4.9275 KW hr or .24% of your last month's bill. At a national average of about $.2 per KW hr the energy out put for one month would be equal to about 60 cents.
Q:have you ever installed solar panels for your home?
Yes I have. We have a little Labrador on the front steps(you know, a thing to hide keys under.) In his mouth is a little lantern that absorbs the solar energy from the panels and it turns on at night. Really saves you money, much more than regular electricity. The bill won't be so high this way, oh, and it's also good for the environment����
Q:How do you connect a solar panel to a motor from an RC car?
can increase your voltage from a single solar panel. In combination with a large capacitor, you could deliver short bursts of power to the motor which would allow intermittent operation.
Q:Why should I use a Charge Controller for my Battery and Solar Panel based on these provided details?
Should I really be concerned with a Charge Controller? Yes. The main purpose of the charge controller is to protect the battery from over charging. Over charging reduces battery life. And spending extra money for a MPPT type controller will get more more useable power out of your solar panel. Would another battery of the same magnitude be helpful in preventing an accident? How much storage capacity does your current battery have (measured in kWH)? A ~$20 Kill-a-Watt meter would take a lot of uncertainty out of how much power you actually use. Even deep cycle batteries suffer reduced battery life from deep discharges. The battery sounds too small for the loads you describe so I would think you would want more. ---------------------------------------... After reading the other answer In a nutshell, with your small 2 volt starting battery, 24 volt panel and a mix of unknown loads, (which is correct), I thought I would elaborate. I had not considered the possibility that you bought a 24 volt panel for your 2 volt battery. Hooking the panel you bought directly to the current battery is a horrible idea. I you were lucky it would just cook the battery in a short period of time. You basically bought the wrong type of panel for a 2 volt system. I assume that there are no controllers on the the market for this situation. If that's the case, I don't know of any good way match the 24v panel to the 2 volt battery.
Q:How much does it cost a factory to make a solar panel?
I think it will cost about %0 Million US for a 50 Mega Watt Factory
Q:Are DIY Solar panels legitimate for saving electricity?
The output of this system will be very small, but it is a staring point. You should consider solar water heating as a way to save on your energy bills. Heating your water accounts for about 25% of your energy use. If you can cut that by 75%, you will save a lot of money. Depending on where you are and how many are in your household, it may cost about $5000 for a do-it-yourself installation. There are tax incentives available that could potentially pay for as much as half of the system. These systems can pay for them selves in as little as 4 - 5 years.
Q:Life expectancy of LEDs and Solar panels...?
LEDs last approximately 50,000 hours of operation, continuous or non-continuous, it doesn't matter. 50,000 hours. Solar panels will, theoretically, last until the end of time. The support structures will fail long before the panels themselves. Inverters, battery banks, op-amps, transformers, control boards, etc. will all fail long before a solar panel stops making juice.
Q:Solar panels for home info?
Of the practical technologies, crystalline silicon is still king. There have been improvements in manufacturing efficiency and price, but the fundamental technology is unchanged. For the past couple decades, there have been startups claiming that they will have a breakthrough available in 2 years, but so far, nothing has beat crystalline silicon for general applications. The appeal of thin-film was its cost, at the penalty of efficiency, but when the prices of crystalline plummeted, the cost argument went away. That wasn't the only problem Solyndra had, but it contributed to the company's demise. Organic solar cells show promise, and might ultimately be very cheap to manufacture, as they don't involve the high-temperature processing that semiconductors do. The main problem today is that they're not stable at the temperature of a hot roof. But then again, a few years ago, organic LEDs were the same way, and now they're commonplace in big TV's. Only time will tell. From a homeowner's standpoint, the install is routine, but still best done by professionals. It's like putting a new roof on a house, or wiring in central air conditioning. For most, it's better to call a pro.
