- 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:how much does it cost to operate a solar panel?
- to okorder.com/ you should really be able make report with this informatin. So for your school it would cost millions, you need to figure out how many kilowatts your school use, then use the information above to calculate how large of system would be required you will be very impressive and the most informed person in your school.
- Q:Why are solar panels placed on the roof of houses?
- The roof is the most popular location for panels, I'd imagine because: ) The space is not otherwise being used. Panels in the yard would take up play space, or shade the garden or lawn. 2) The roof is usually more free from shadows because it's high up. Something low to the ground could more easily be shaded by trees, fences, or nearby buildings. 3) The roof often has a built-in tilt that is more ideal for panels. Take a good look at your roof, especially if there is a south-facing side. The roof could be bigger than you think. Only 0% of our roof area is dedicated to solar panels, and that keeps up with our yearly electrical usage.
- Q:Question about using solar panels......?
- I don't think it is enough solar power. Your motor requires .5A x 9V = 3.5 watts. The solar cells are .450A x 4V x 2ea. = 3.6 watts, .2A x .5V = .3 watts, .A x 9V = .9 watts total solar = 4.8 watts. The problem with connecting the cells in series to get the right voltage, like the two 4V cells in series with the .5 volt cell (total 9.5 volts) is that the .5 volt cell limits the maximum current to only 0.2A. If you paralleled that with the 9V cell, you would get 9 volts at 0.2 + 0. = 0.3A, too low to operate the motor at its design current and voltage. The best you could do is put the two 4V cells in series, and in parallel with the 9V cell (a blocking diode might be a good idea, but probably not required for such a small array). That way you get 8 volts at 0.55 amps.
- Q:questions about solar panels for residential use?
- What's your Source (Optional)
- Q:What is so great about solar panels ?
- Solar panels are eco friendly, they produce with out disturbing the enviroment. Instead of having to build dams and kill of species that have water homes we can use the sun as our energy source. im all for solar panels i hope this helps :)
- Q:how long does it take for a solar panel to make one watt?
- Well, a 5 Watt solar panel running for an average of 2 hours per day, (there will be clouds), will put 5 * 2 = 80 Watt-hours into the battery. Assuming your inverter, (to convert 2 Volts D.C. to 20 Volts A.C.) runs at 00% efficiency, that will only supply power to run the grill for about 22 minutes a day. In the real world, neither the battery nor the inverter will work at 00%, to your actual heating time will be significantly less. If you get about 0 more of those 5 Watt solar panels, that would give you about 50 Watts * 2 hours or about 800 Watt-hours which would more than cover what you want to do. The next problem is getting an inverter which will handle a 700 Watt load. They can be found at auto supply houses and the larger truck stops. (They are popular with semi-drivers.) Note however, that a standard car battery will have to supply about 55 Amps, which means you will have to use some really heavy wire, like # 4 or # 6 welding cables to connect the inverter to the battery to minimize losses. P = 700 Watts E = 3 Volts I = 53.84 Amps R =
- Q:Solar Panel, what is the catch ?
- Read the terms and conditions! They will own the panel and receive payment for any power generated from it, as one example.

Anatomy of a Solar Cell 5. Energy Loss in a Solar Cell 6. Solar-powering a House 7. Solving Solar-power Issues 8. Solar-power Pros and Cons 9. Lots More Information 0. See all Physical Science articles You've probably seen calculators that have solar cells -- calculators that never need batteries, and in some cases don't even have an off button. As long as you have enough light, they seem to work forever. You may have seen larger solar panels -- on emergency road signs or call boxes, on buoys, even in parking lots to power lights. Although these larger panels aren't as common as solar powered calculators, they're out there, and not that hard to spot if you know where to look. There are solar cell arrays on satellites, where they are used to power the electrical systems. You have probably also been hearing about the solar revolution for the last 20 years -- the idea that one day we will all use free electricity from the sun. This is a seductive promise: On a bright, sunny day, the sun shines approximately ,000 watts of energy per square meter of the planet's surface, and if we could collect all of that energy we could easily power our homes and offices for free.
- Q:making your own and installing solar panels. Bull s*** or not?
- If you're in Hawaii, number one, be sure to get a solar water heater. Guaranteed fast payback. Now about those kits. Avoid the kind that says you can make your own panels for under $200. Those are scams. If you're in CC of Honolulu, you will not be allowed to connect that kind of panel to your house - it doesn't meet National Electrical Code because it doesn't have a safety rating like UL. There are kits for grid-tied solar that run from $6000 on up. That's the kind that can actually save you money. I don't know whether you are allowed to install it yourself, though. In California, you can, as long as you get the inspection, same as any other building project. In spite of being further south, Honolulu gets about the same amount of sun as we do in San Jose, California. That's because our area is dry, and you have more clouds and rain during an average year. If you're in one of the wet valleys like Manoa or Palolo, obviously the situation would only be worse. But your electric rates are high, so you have a good chance of making your money back. Very few sites are really good for wind turbines. You cannot just put it on your roof in the city - it needs to up high, where the wind is strong and steady. That's why you see turbine mounted on towers. Also, because it has moving parts, it's going to wear out. Finally, you know how cars rust out quickly there compared to the mainland? Same thing with a wind turbine.
