Q:how does solar panels work?
Solar panels collect solar radiation from the sun and actively convert that energy to electricity. Solar panels are comprised of several individual solar cells. These solar cells function similarly to large semiconductors and utilize a large-area p-n junction diode. When the solar cells are exposed to sunlight, the p-n junction diodes convert the energy from sunlight into usable electrical energy. The energy generated from photons striking the surface of the solar panel allows electrons to be knocked out of their orbits and released, and electric fields in the solar cells pull these free electrons in a directional current, from which metal contacts in the solar cell can generate electricity. The more solar cells in a solar panel and the higher the quality of the solar cells, the more total electrical output the solar panel can produce. The conversion of sunlight to usable electrical energy has been dubbed the Photovoltaic Effect. The photovoltaic effect arises from the properties of the p-n junction diode, as such there are no moving parts in a solar panel.
Q:Are solar panels efficiency already calculated in their power rate?
Solar panels are tested in a lab that has a light the produces 000 watt/hrs per square meter. In these conditions your panel will produce 80 watt/hrs. If you would like to know what it does in really world conditions you have to find the sun-hours in your given area. A sun-hour is basically how many watt/hrs hit a square meter in a day. This number changes based on time of year, orientation, and temperature. Here in Fairbanks Alaska if the panel was at 90 degrees facing true south in October (.9 sun-hours) It would produce 80 X .9 X .8 (20% efficiency loss due to wires and controllers) it would produce 273.6 watt/hrs on average each day.
Q:What Size Solar Panel Would I Need?
I know that in Texas we wouldn't even try to run an air-conditioner on a generator without at least a 6,000 watt generator and we would prefer a 0,000 watt generator. The calculator on the Kohler website says it'll be 7,500 watts. At $5 per watt to install a solar photovoltaic system and assuming you also need to run it through the night and taking into account that an inverter can be as bad as 60% efficient, you're talking about $87,500 just to run your AC for 25 years. The first step in going solar is to significantly reduce your energy use. You're not going to maintain your current energy use on solar, at least not cost effectively. If you did want to run an AC on solar power, you may want to look at absorption air conditioning and use evacuated tube solar thermal collectors instead but don't expect it to be cheap and it usually only augments the use of natural gas in the absorption chiller.
Q:can you hand make a solar panel?
If you want long term working ones then no. I have not seen the web instructions ones, but solar panels that are manufactured are a lot more complex then simple solar panels that you make in your backyard. Also, you need to have some type of turbine or other thing to change heat energy into electrical energy. For a non science person to try and do this and have it work the first time maybe hard to accomplish.
Q:I need some ideas for a going green program involving solar paneling.?
Solar Energy Is School! It's School To Go Solar!
Q:Why are solar panels not that efficient?
The latter link has a decent explanation, if not a bit technical: One of the most fundamental limitations on solar cell efficiency is the band gap of the semiconductor from which the cell is made. In a photovoltaic cell, negatively doped (n-type) material, with extra electrons in its otherwise empty conduction band, makes a junction with positively doped (p-type) material, with extra holes in the band otherwise filled with valence electrons.
Q:Anyone have or know someone who has solar panels installed in their home? Is it worth getting?
and, if given the tax credits, you'll see a faster return on investment in CA than I would have in Western PA (I was given a 0 year return number without factoring any tax credits). Plus you'll be doing something good for the environment. My brother put his house for sale which had solar panels for hot water, and was offered good money for the solar panels independent of selling the house. If anyone has a any no answer that doesn't involve the initial expense, I'm looking forward to reading it.
Q:What to do with a solar panel?
Solar cells convert the energy of the sun into electricity. By using items commonly found in the home or your local hardware store, you can make a solar panel to demonstrate this photoelectric effect. You can also save energy by converting some of your traditional electrical supply over to solar power. Use sheet metal shears to cut the copper flashing in a square or rectangle to fit the size of the electric burner. Be sure to use a piece of copper flashing that is thoroughly cleaned. You may use sandpaper to thoroughly remove any sign of corrosion before proceeding. Place the copper flashing on the electric burner and turn the burner on. You will need to cook the flashing for as long as 30 minutes or more to develop a thick layer of black cupric oxide.
Q:Question about home solar panel systems?
As Ed said, that .2 kW is an instantaneous rating in bright sun. The way to do this right is to consult the maps here rredc.nrel.gov/solar/old_data/nsr... to find the number of equivalent sun-hours your location gets per day. Select, Average, Annual, Flat plate tilted south at latitude. A map will come up. For northern California, it shows 5 equivalent sun hours per day, for example. If the system is .2 kW, then .2 x 5 = 6.0 kWh of energy the system will generate per day, on average. That takes into account cloudy days, short winter days, long summer days, everything. The 2.4 kW system would give double that, obviously. But that's an example, based on a specific location. Phoenix would do better, Seattle would do worse.
Q:Solar panel wiring, materials?
It does not matter if you father is a electrician he must be a fully qualified solar installer or you will not receive any money from the government. You need more than just solar panels you need regulators, grid interaction devices and array controller. 5KW installation is large and will cost around $5000 for the panels then around 5000 for controllers and equipment needed and then there are the basic materials such as rails, junctions, cables etc Total cost is approx $5,000
