- Q:hi, i got a pond and i am planning of putting some lights on it during night time. but i want to use solar panels and i have done a bit of research about solar panels and i know how they work, i know that the common voltage to use is 2v so you can use car batteries or deep cycle batteries, but my question is:. what wattage of bulb can you recommend2. how long it would take to drain my battery (can i have it overnight)3. and what wattage of solar panel should i get enough to recharge my battery the next day.hope anyone can help..thanks
- select 2V, and it will tell you how big of a battery bank and how big of a solar panel you need. For my example, I need a 7ah 2V battery and a 20watt panel.
- Q:The average solar panel produces 0% of the energy that is put into it. What is happening to the other 90%? Is it being reflected or is it being obsorbed by materials that are not a part of the solar cell? Is it possible to one day have near 00% efficient solar cell technology?
- Mainly due to reflection (micro-structuring of the surface helps here), incorrect wavelength of the light (the panel is only sensitive to a certain wavelength range) and heating of the panel (due to the incident light/thermal radiation). The remainder is either reflected or absorbed by the cell and re-emitted as heat. Absorption by e.g. the glass panel is slight (a few %), as is absorption/reflection by the necessary surface contacts (again, a few %). Higher efficiency is possible, but brings its own drawbacks (like higher cost). You could now go into two directions: - high efficiency cells/panels with (likely) higher cost and complexity for mounting (like lens or mirror based systems, aka concentrator systems, that increase the light level on the cells in order to increase efficiency) - low cost systems (cheap as dirt) that will allow you to cover every surface of a building, efficiency is less important if you can compensate by a much larger covered area As to the efficiency limit: there is a theoretical limit (from thermodynamics - don't ask me how or why) in the range of 30...40%, depending on which publication you want to believe in.
- Q:Simplfy it so i can understand pls and put it in stages such as . sun hits solar panel plsHow many different types of solar panels are there?
- Solar panels are made of a series of solar cells.solar cells are an electical device that convert sun energy directly into electicity by the photovoltaic effect,which is an physic and chemical phenomenon.solar cells are made of special materials called semiconductors such as silicon,which is currently used most commonly.Basically, when light strikes the cell, a certain portion of it is absorbed within the semiconductor material.This means that the energy of the absorbed light is transferred to the semiconductor. The energy knocks electrons loose, allowing them to flow freely.This flow of electrons is a current, this current, together with the cell's voltage (which is a result of its built-in electric field or fields), defines the power (or wattage) that the solar cell can produce.
- Q:I'm doing a science fair experiment with a tiny two-inch solar panel that only gives off like .5 volts of energy, but I need to know how many volts an average sized solar panel (like one you'd get to run your house) would produce. And how many panels do people usually get?
- You should read up on the different electrical units. You say .5 volts of energy, but this makes little sense. Energy is measured in Joules. Power in Watts. Solar panels will produce different voltages and currents, depending on the amount and angle of sunlight hitting them. Power = volts * amps. Before installing solar panels a home owner should do an energy audit to find out how much power they currently use - and how much that could be reduced with some easy changes. Solar panels are expensive, so it makes sense to reduce the amount that you need to install. In some places you can sell extra power back to your utility - so having extra panels might give you some small amount of money back - but this is rarely enough to justify the cost of the extra panels. I put 28 panels on my house (see picture in source URL). My utility has tiered pricing for electricity (first few kWh each month are cheap, but price for extra ones goes up in stages). My panels keep me from having to pay the higher rates.
- Q:How much per sq inch do they cost? Will i have to worry about them blowing off during hurricane season? If the sun isnt out for a week will my power go out? Will I have to check them every week and check which ones arent working and replace them? Is there anyway for them to be damaged by acid rain or any type of erosion like hail? When do I have to replace them? How do I dispose of old ones (like recycling)? What is smarter and more economical having few big panels or many small ones? I know I have alot of questions but I want a good detailed answer.
- The cost of solar is measured in dollars per watt. That means the cost of a cell that can make one watt continuously in full sunlight. A friend of mine is starting a new job to set up a new solar cell factory and he said the present cost is $3 per watt, but that they expect to get that down to $ per watt in a few years. They can be damaged by weather, just like any regular roof. My insurance agent asked if I had solar panels, so it is a factor in insurance cost. I never heard of recycling or disposing of old panels, maybe because they are so new and last so long that not many are ready to be disposed of yet.
- Q:Hi, I am very interested in solar panels and would like to know more.Can someone please give me a basic explanation of how solar panels work?Thank you
- A solar panel is a panel of a certain material that is very sensitive to light. Now, when you place if out in the sunlight, the photons enter that material, and gets converted to energy in the form of electrostatic electrons. These electrons gets carried away by the small silver wires you see running zig-zag over the panel, and is then used as electronic current. It is actually a lot more intricate and detailed than this, but this is more or less how it works. The reason is works better in sunlight, is simply because sunlight has a lot more energy behind it than lightbulbs and other sources, but they work as well!
- Q:Which kit did you use?How easy was it to build? How much did it cost to build the panels?How many kw or watts does it produce?Any other info on the kit or panels you built would be helpful.Thanks!
- I am starting to think about solar panels as an option for my home. I have d fef one some research on panels, to be honest its all very confusing. There are many.???Read more...
- Q:The intensity of sunlight at the distance of the Earth's orbit is 380 W/m2. An Earth-orbiting satellite has a solar panel that measures .35 m by 4.86 m, which converts solar energy to electrical energy with an efficiency of 26%. In one hour, how much electrical energy does the panel produce? Assume that the satellite's attitude control jets keep the panel oriented perpendicular to the incoming sunlight.
- 380 W/m2. An Earth-orbiting satellite has a solar panel that measures .35 m by 4.86 m, which converts solar energy to electrical energy with an efficiency of 26%. In one hour, how much electrical energy does the panel produce? 380 W/m? x .35 m x 4.86 m x 0.26 = 2354 watts energy is watts*time E = 2354 watts x 3600 sec = 847472 Joules or, E = 2354 watt-hours
- Q:HIToday i was using my BB gun and shot my dads solar panel. I want to fix it for him because he spent a lot of time trying to get the solar panels. All i broke was the glass on the front, what is the glass and where can i buy new glass for it?
- Even if you can buy solar glass, you CAN'T properly repair the panel for the cost of having a professional do the work.
- Q:For a computer technology project we are using solar panels and trying to see different methods that will increase the output of solar power from these panels. For now, we have got polymer stickers and mirrors. Are there any more methods, or information that increase the solar power? Please and thank you :)
- I am a senior in highschool and one of my classmates is basically a genius by all means that I can tell. He has already been accepted yo UNC Chapel Hill. His admissions statement was on exactly this subject. I proof read it for him. Anyways the basic problem with solar energy is that we can only harness about 20- 35 pecent of the energy and even less of that is converted into energy that can acutally be used. His argument is that if somehow we could harness chloraphyll which is the chemical which plants use to harness the suns energy and incorporate it somehow into our solar panels. We could harness up to 95% of the suns energy!!! Id deffinately look into this.
