Q: What are solar panels?
Solar panels are a collection of photovoltaic cells, that are used to generate electricity, from light. Here is the simple explanation from wikipedia, concerning photovoltaic cells . Photons in sunlight hit the solar panel and are absorbed by semiconducting materials, such as silicon. 2. Electrons (negatively charged) are knocked loose from their atoms, allowing them to flow through the material to produce electricity. The complementary positive charges that are also created (like bubbles) are called holes and flow in the direction opposite of the electrons in a silicon solar panel. 3. An array of solar panels converts solar energy into a usable amount of direct current (DC) electricity. Solar panels are used extensively for power generation in many places, but most space applications (like satellites and spacecraft) use solar panels. If you look at a picture of the current configuration of the International Space Station, the giant wing things are the solar panels.
Q: Can solar panels be used on boats or RVs?
Yes, solar panels can be used on boats or RVs. In fact, they are a popular choice for these applications as they provide a reliable and environmentally-friendly source of power. Solar panels can help to generate electricity for various onboard systems, such as lighting, appliances, and charging batteries, making them an excellent option for those seeking off-grid power solutions while on the move.
Q: my solar panel is 5v 50 mA, and im making iphone USB charger so i need to connect + with 00 ohm resister and to data - and + so what resister will be okay..?
Just connect the 5 volts out of the panel directly to the iphone via an USB connector. BUT, is the panel output always 5 volts, ±0.25 volts? Because that is the USB specification, and anything outside of those values could damage your iphone. And solar panels are known for their wide swings in voltage. Bottom line, resistor not needed, and you need to be positive you supply the correct voltage to the iphone. Best way to do that is to start with a solar panel that puts out at least 7 volts and use a LM7805 regulator. The only resistors needed are those to tie the data lines into a certain combination of resistance and voltage so that the iphone is fooled into thinking that a proper USB is connected. That would NOT involve a 00 ohm resistor. Search online for the proper values and connections. edit: are you repeating your same inane question with a different account? That is totally against the rules and could get you suspended.
Q: Can solar panels be used in areas with high levels of pollution from industrial activities?
Yes, solar panels can be used in areas with high levels of pollution from industrial activities. While pollution may have some impact on the efficiency and performance of solar panels, they can still generate electricity even in polluted areas. It's important to regularly clean the panels to maintain their optimal efficiency and ensure maximum energy production. Additionally, investing in advanced technologies and air pollution control measures can help mitigate the effects of pollution and improve the overall effectiveness of solar panels in such areas.
Q: Composition and function of solar panels
Among them, for the electronic grade polysilicon accounted for about 55%, solar grade polysilicon accounted for 45%, with the rapid development of photovoltaic industry, solar cell demand for polysilicon growth rate higher than the development of semiconductor polysilicon, is expected to 2008 solar polysilicon
Q: I have tried researching on the internet and just cant find any real answer. I know that the amount of electricity produced when taking in the suns rays depends on the placement of the solar panels but I am just looking for ball park figures. Thanks
call your power company and ask them how much they pay for each kWh you feed back into the grid (the price may vary for different times of the day). then multiply that by however much electricity you are producing.
Q: Any recommendations for companies? Any things to look out for?
It depends upon the way you look at things. If you are searching for a good return on financial investment, or maybe a company conclusion, it is probably extremely unwise. In most cases individuals might see a better return in upgrading insulation in ceilings, walls, and windows to a lot better insulation than they presently have, followed by proper resizing heating and additionally air conditioning to small unit size to suit their lower need as an outcome of the insulation. The warmth a particular air conditioning models ought to be the greatest efficiency available. The return in the above can make a favorable and also financial financial investment quite often. If you have done the above mentioned very first, and also have cash to spend and also do not proper care about the return in it, then chances are you can play with solar or perhaps wind. Unfortunately, typical cost of age bracket of solar powered and also wind energy is about $0.22 / KWH and you may order from utility at about $0.0/ KWH including generation and also distribution so this is simply not every one of the that prudent.
Q: can you buy single solar panels say to power a washing machine fridge etc.if so where can i buy them from
Yeah, just find out how much electricity your fridge or washing machine uses, (look on the internet), and buy solar panels for just that amount of energy. Solar panels can power from watt to 224 watts! ~MaDiSoN
Q: How much would it cost (approximately) to convert my home (3 bed. 2 bath) to a green home that is run entirely upon solar panels on my roof? From the panels through installation does anyone know a price break down?
Check your electric bill, and see how many kilo watt hours you have been using for the last year. That will give you a clue as to how many panels you will need in the array,and how many batteries you will need, what size inverter is needed plus would you want a true sine wave or modified.And that's just for starters. But of course you might get a break from your electric Co.(Rebate) also from your state,and possibly something from the Feds. I have installed on the travel trailer a 25 watt panel($850) a 22amp.charge controller ($45) a pair of Trojan 425 watt 6 volt batteries ($300 each) and a 2000 watt inverter modified sine wave ($2000).The only thing I can not run with this set up is the A/C which requires 3000 watts of power. So as you can see your project could get very expensive. I hope this sheds enough light on the subject for you.
Q: i need someone to advice me which solar panels to buy.i have looked into few companies and i need some more info before decidingthe companies i checked were Sun tech trina solar Canadian solar and LDK solar.whice company should i pick?? please help.
I did that 25 years in the past and happy I did. they're nonetheless operating high quality with little upkeep. we stay in necessary large apple so we've about an same type of cloud cover you do, and at the same time as that is no longer suitable, you could make it artwork. the nice and comfy button isn't spending plenty so that you've a life like payback time. I designed and outfitted my own, yet i did not layout for top performance; and at the same time as it would not generate all our warm water each and each of the time, it takes the edge off our gas bill. locate someone who has them and note if it paid off for them. don't be the first to get them until eventually you opt for to do slightly engineering. image voltaic voltaic panels could no longer be used to warmth water electrically, that is truly inefficient and could no longer payback. DHW heating is low-tech and all and dissimilar needs warm water. Voltaics receives extra valuable in years yet to go back, and expenditures are dropping so it would not make experience to purchase now.
