Q:I'm about to buy one but I don't really know which one is best for my home.
Talk okorder has good info. What state are you in?
Q:Can solar panels be connected directly to motor?
The sun is irradiated on the semiconductor p-n junction to form a new hole-electron pair. Under the action of the p-n junction electric field, the holes flow from the n region to the p region. The electrons flow from the p region to the n region, and the current is formed after the circuit is turned on.
Q:I have a 20 watt solar panel that I want to set up. I need to connect it to the solar controller but do not know what cable to use. I plan on adding more solar panels down the line. What would be the best cable to use?
How long is the run? 2 gauge is a good choice for runs up to 25 feet at 20 watts, if you are much further in your run, move to 0 gauge to reduce resistance of the wire itself in the circuit. Otherwise refer to the prevailing electrical code of your local unit government. This is a must if you plan to maintain insurance. At lower voltage, a little resistance means a lot. 4 gauge might be okay for 20 VAC, but the voltage drop on a low voltage system from resistance of the wire itself is measurable at 20 feet. It is the difference between a light fixture working or not. If you are planning on adding additional panels in the future, you can get terminal buss with screw hold downs at various vendors like Mouser or Digi key. Each panel can be on it's own screw, while the buss is common on the other side of the connection. one for the positive and one for the negative.
Q:I am wondering how to store energy from a solar panel
I have no idea what you are doing or what you think you are accomplishing. A 235 watt panel isn't much energy. You can certainly store it with a plain old lead acid battery.
Q:Hi.How efficienent are solar panels? I mean, suppose we install a kw panel.. Wil it produce 5kw in 5 hours of good sun light?Or like if its 80 percent efficient, wil it produce 4kw and so on.Also, do the chinese solar panels give the same results as compared with panels from other countries?I live in india, so we get plenty of sunlight during the day.Thanks
The panels themselves efficiency are 5 to 8 percent at converting sun energy to electicity currently.But as what you said above,the conversion efficienc is about 70%,so a KW solar panel can produce 3.5KW in 5 hours,The solar panels of China are compared comparably to other contries.The highest efficiency of 24% is rare,they are not widely avaliable.
Q:What is the proper diode to use on an 5v 500ma solar panel?
At least a 2 amp diode. rated above the 2 volts that are commonly found on the market. A blocking diode must be able to stop a higher current and voltage than the panel maximum. A diode will work on any voltage and current lower than it rating.
Q:How much candle lights is required to operate a 205 watt solar panel?
That's hard to tell. A solar panel produces somewhere between 7 and 0W per square foot under sunlight exposure. You should calculate the light intensity of sunlight, and then calculate the light intensity of a candle (You'll have to look that up in some physics book or the internet) and then just multiply the number of candles until you match the intensity of sunlight. Realistically, you would need so many candles that you wouldn't be able to fit them in front of the solar panels, assuming you don't end up with a huge fireball.
Q:Can anyone tell me how to connect a solar panel from a calculator 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:how many solar panels in a grid tied system would it take to take see a difference in your power bill?
Typical solar panels used on household systems generate between 00 and 50 watts each. You might get the equivalent of five hours of sunshine per day on the average. 500 to 750 watt hours per day would be the average output. Where I live that would save only about six to nine cents per day. Learn more about photovoltaic solar systems by searching for solar panels on the Internet, and in the green search box above on this page.
Q:Are you a Solar Panel Specialist/Genius/Enthusiast?
No, just an amateur. I guess that could be called an Enthusiast. I think most people find the topic somewhat interesting, some more than others. Why do you ask?
