- Q:Im a bit confused about what a solar panel is?
- Solar panels are arrays of individual solar cells connected in series and parallel, and.. A high quality, monocrystalline silicon solar cell, at 25 °C cell temperature, may produce 0.60 volts open-circuit (Voc). The cell temperature in full sunlight, even with 25 °C air temperature, will probably be close to 45 °C, reducing the open-circuit voltage to 0.55 volts per cell. The voltage drops modestly, with this type of cell, until the short-circuit current is approached (Isc).
- Q:Have a 40watt 20volt solar panel, how many watt of inverter do I need?
- It depends on what you want to run from the panel. A 20W inverter might last a long time, but would not run much. A 00W inverter might run down your batteries in a few hours. It might help if you posted how much capacity (Volts, Amp-Hours) the batteries have.
- Q:help setting up a solar panel system?
- ever looked at the light from a 45 watt bulb? it's true that in a cabin, if you're in the right place, you can read from it. however, assuming that you get 6 hours of sun, you can run your light for 4-5 hours. and nothing else. if you're hoping to run a stove, you're going to need several hundred watts. not sure what tools you're thinking of, but i don't know of many that run on 2v DC. (not sure that i know of a stove that runs on 2v DC either, but you can look that up.) for tools, you might want to consider a gas powered compressor and air tools. that'll give you the strength that you need. yes, i know that's not what you were thinking, but pretty obviously you're going to need to do a bit more thinking. even a minifrig is going to use considerably more than 45 watts. and that would be 24 hours a day. remember, a minifrig has considerably less insulation. you can't save much and per pound, it takes more juice.
- Q:How to tie small solar panel system into my house's electircal system?
- For one thing, you would be trying to supplement the entire electrical grid. Same reason you must have a cut out relay for an emergency generator. Cause without one, you generator would be trying to power the whole regions electrical system. You could set up a solar system to just power specific things, like a gate opener, etc. But thy would have to be wired separate from the house a.c. electrical system.
- Q:what colour can solar panels be ?
- Panels can come in a selection of colors, and trimmed in a variety of frames. Most are dark, black, blue or reddish in hue. Concentrators may appear white from a distance. Kinetic back up is possible in the form of a flywheel. Not very common but it is out there. Another form of kinetic backup that is used by some power companies is hydro. When the sun is out and the system is producing more than is used, the excess can be used to pump water uphill to a holding tank. Then when there is a demand, the water is allowed to flow back down turning a turbine to generate electricity.
- Q:what are bad things about solar panels?
- They're really expensive. If you want it for practical use like a house or car powering system. They're bigger than like a battery if you're comparing size to power. Like a car battery can produce more energy than a 6 x 4 panel (just an example)
- Q:Solar Panel Question...?
- The best way to find out is to determine the wattage of each piece of equipment you want to use and how many hours you want to use those pieces of equipment. Finally, calculate the total number of Watt-Hours you need at minimum. Then you need to research solar panels or mobile wind mills (they need to be pretty huge to get a decent amount of energy I think, so solar power is probably the way to go). You will need to figure out the efficiency of the solar panels, the size of the array, how you will turn it or if you will turn it at all (to face the sun to get the maximum energy input, or maybe to use mirrors so you don't have to turn it. Once you find a good configuration for your mobile kitchen, you need to calculate if the Watt-Hours you will generate on an average day (with average weather) is enough to power the equipment whose energy requirements you previously calculated. Then you have to keep in mind that some days will have no sun, and you may not be working on some days, but you can still capture sunlight. For each case, a large battery array will be required. If you had a guage on that array, you could also hook it up to the a small generator in case you need immediate power. It's an eco-friendly process, but the initial cost is high and it requires a lot of research and planning. This is why most people do not do it--not because they don't want free energy from the sun, but because it's not easy to start collecting that energy in an efficient way. Sorry I couldn't give you more specific numbers, but a solar panel sales agency should be able to estimate whether or not you could do it (they'd probably set it all up for you too). ^_^
- Q:Is it worth installing solar panels on a house that has no South-facing roof?
- The trouble is that it is so expensive to have installed and as you say it will take many years before you actually start saving above what the installation cost was, I personally would not go ahead and make that sort of investment, it would be more profitable to keep the money in a building society, get the interest from it and use that to pay for your electricity but the main thing that I have against solar Panels is that unless you stay in that house for at least twenty five years you will not reach the point where you are saving and to capitalise on it you would have to stay there for many years more, so you will not have the option of moving house without losing your investment and at the moment having solar panels does not increase the value of the property, it is just a good selling point, when you buy your new house, you would probably have to start all over again and then because of the years will never live long enough to reap any benefit from it.
- Q:Solar panel battery charging?
- I agree, you should get a charge controller and install appropriate fuses.
- Q:Designing 3d Solar Panels?
- I don't know anything about the 3D thing. You cannot get more energy out, than goes in. Energy will only hit the mirrors. With some loss of efficiency they would reflect a focused beam into the chamber, where with some more losses would reflect it to the solar panels. It would be more efficient just to expose all the panels to sunlight.
