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:Do you need to pay for electricity if you have solar panels?
I think that rustoria67 bumped his head on some thing. There are thousands of homes using only solar panels to power their homes, and it no way near an acre of them. With the right setup Kw of panels will work. Remember one can't bring a boat to an airplane race and hope to win. Look at this link.
Q:time till a solar panel pays itself off?
lots of info about solar panels, perhaps you'll find answer to your question renewableenergyarticles.blogspot....
Q:List of new solar panel manufactures?
Leading vertically-integrated PV company. Manufactures top-quality Poly-Si/Mono-Si modules in India. The company distributes/provides solar-power systems services worldwide. USAManufacturer and developer of high-performance silicon solar cells. Their proprietary Bright Point technology utilizes impurity-enriched silicon to efficiently convert the sun’s power into electricity. Suniva develops, manufactures and markets high-efficiency silicon photovoltaic (PV) cells. Suniva's focus is solely on silicon PV cell technology and manufacturing and does not engage in any of the downstream integration or manufacturing of modules or products which use its cells.
Q:how to hook up solar panels to meter?
Contact your power company. They will advise you of the proper configuration. If you try to attempt this without notifying the power company and something goes wrong, they can and most likely will hold you responsible for all damages.
Q:What kind of Solar Power panel setup do I need for this?
Unfortunately solar panels are low output,generally only 2 volt and very low amperage,so you would need to build a multi panel array with a DC-AC converter all together costing several hundred dollars which would only work during sunlight.Just roughly figuring,about $800. Plan2-Solar charger,battery bank,and DC-AC inverter so it would work 24hrs a day,also several hundred $$. Solar power does just not seem feasible(to me)in this application.By far the cheapest set up here would be an extension cord fromhouse to the bucket.260 watts per hr is a fairly lightweight draw,even not figuring the thermostat's cycling it on and off as needed.Electricity is sold in kilowatt hours(000W/hr).This bucket would use(not allowing for thermostats control lowering it)appx 6000watts or 6KW per day.Depending on your electrical cost per Kwh it would cost very little to run.(In my location appx 50cents a day) or appx the same amount as my computer(325watts total)) Note that that would be a maximum rate,and would actually be less due to thermostat cycling off and on as needed.
Q:Want to power this with solar panels?
You won't get very far with THAT lash-up. First of all.. WHY would you want to use diodes to drop the voltage.. they DRAW CURRENT and that is something you don't have to spare. That draw of 4.5v@0.66A (660 ma) comes out to just under 3 watts. You DO KNOW that you can get that 4.5 Volts by driving a NAIL into the THIRD CELL in a 6 Volt wet cell battery... right? and for what you are doing, you have more current available with a 6 volt battery than a 2 volt battery. Anyway, you could use two 6 Volt batteries and tap them at the 4.5 volt point then tie them in parallel, but you could still use the 6 volt solar panel to charge them. Trying to use an inverter is just an exercise in futility.. With TWO of the LARGEST DEEP CYCLE BATTERIES you can buy at AutoZone running in Parallel and being charged by solar panels.. if you hook a 75 watt inverter to them, they will go flat in about 4 hours of use during the night. This is not rocket science. Back when cars were changing over from 6 volts to 2 volts, I powered up more than one 6 volt car radio off a 2 volt battery... when you grow up as poor as I did.. you get inventive. I later used the same trick on the 24 volt electrical systems the Jeeps were using, to power up clandestine repeaters in places where no repeaters should have been. About 25 years ago I was living in the Denver area and built up a 0 watt 2 meter repeater on a split channel and took it up to Mt. Evans during the summer and hid it in a pile of rocks. I used tone control, so we were the only ones using it and, as I said, It was a split channel.. so it wasn't on a regular repeater channel. That thing was still running when I moved from the Denver area about 3 years later and for all I know, It's still up there on Mt. Evans (find the Brittlecone Pines and look towards that small peak about a mile to the west)
Q:Questions about solar panels?
There are several web sites you can search for and they will provide the answer on how big of a PV Solar Array you would need for your house. Several things need to be known, such as square footage of the home, how well the home is insulated, etc. The panels come in all sizes and wattage's depending upon application, so yes they should all fit on the roof. If you have a small roof get PV panels with higher wattage's. Yes, they will work in the northern latitudes but not as efficiently as near the equator. You might need more PV panels to make up the loss in power from the sun hitting at a lower angle. Generally, all you will need to do is periodically clean the glass covering of the PV Panels to get maximum sun light on the PV cells. In my region, near the 45 th parallel, a 600 square foot home with six inch insulated walls and R40 attic insulation can purchase a PV panel system for around $40,000. That includes the equipment to tie it into the power grid and the meter to measure how much you supply the grid during the day and how much you draw from the grid at night when the sun isn't shining. There are tax credits for retrofitting an existing home, but mostly it is new homes being built that are having the PV panel systems installed so the cost is added to the mortgage and the return on the investment is paid off over the life of the System (about 5 to 20 yrs.)
Q:Why should people use solar panels more for houses?
Right now, the U.S. government and some state governments (like California) are offering subsidies on solar panels for businesses and houses. With these subsidies, anyone infesting in solar power today will have their investment returned in less than 0 years. This means that with these subsidies, solar panels are basically paying for themselves; they're free. In addition, excess power generated on solar panels can be added to the local power grid and, if you're lucky and can set it up with your local power distributor, the power company will pay you for the power you generate. This are just financial reasons. Their is also the reduction of power generated by fossil fuels when using solar power which mitigates climate change.
Q:in a solar panel, where do the protons go?
silicon based photovoltaic cells used some boron as dopant. i dont understand if that helps supress proton pastime, the way they be conscious boron on supressing run away nuclear reaction.... im clueless as you
