Q:Is there a free solar panel program for veterans?

Q:highest known watt output for solar panels?
in case you raise a dumb-bell a undeniable style of feet, you have expended a undeniable volume of potential, does this variation if the gymnasium exchange into on yet another floor of the construction? Grounding is needed for defense and to dodge floor loops from happening, the quantity of potential produced would not exchange and any adjustments in potential will bring about a risky floor loop attempting to equalize it.
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:Single crystal solar panels and polycrystalline solar panels
Monocrystalline silicon cells in the laboratory to achieve the conversion efficiency of 24.7%. Ordinary commercial conversion efficiency of 10% -18%. Monocrystalline silicon solar cells because of the production process problems, generally its semi-silicon ingots for the cylindrical into, and then through the slice -> cleaning -> diffusion knot -> remove the dice -> the production of electrodes -> corrosion around -> Reflective film and other workers made of finished products. General monocrystalline silicon solar cells four corners for the fillet. Monocrystalline silicon solar cell thickness is generally 200uM-350uM thick, and now the production trend is to ultra-thin and efficient direction
Q:how does solar panels save energy?
Solar panels doesnot work on electricity.They absorb solar energy emitted by sun and thus work without the usage of electricity.If we use them then there will be automatically reduce the elctricity bills as we dont need to switch on.They use natural source to switch on for which we don't need to pay.
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:SOLAR PANELS (sun enerjy)?
Grid-tied solar systems in the U.S. run at least $8/watt installed. To completely run a 2,000 sq ft home, you'd need about 50 amps service from solar -- both 20 volts and 240 volts. Not very practical. Panels are expensive, but the BOS (balance of system) is as well. You need mounts to bolt the panels to the roof (same thing if ground mounted). Cable, wire, and connectors will run several hundred dollars. A couple of grid-tie inverters in the range of 4,000 watts each will cost you several $6,000 to $8,000, plus sub panels, combiner boxes, breakers, disconnects, charge controls, and batteries, among other things. You'd likely need 5 to 24 panels, depending on too many factors to mention here. You'd need at least 8 batteries, likely 2 volt ones, probably more if you want to run the entire home from solar. Solar (or wind) systems have to be installed in the U.S. by state licensed installers, and there are not many of those yet. And if you grid-tie the system, you'll need to put an interconnection agreement in place with your local utility, plus the utility will have requirements on the net-metering and installation of a switch they can use to turn your solar system off from the grid. And this would not produce hot water in the way you are thinking. If you have an electric hot water heater now, the solar system could help run that, just like the rest of your home. Hot water from solar and electricity from solar are two completely different technologies.
Q:What are solar cells made of?
Solar cells are mainly made of a semiconductor called silicon,when sunshine on it,solar energy is converted into electrical energy by photovoltaic.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:Solar Panel Efficiency?
When it exposed to light, it starts generate electricity. Now the 200W written on panel is not its all time power. Its Watt Peak (200Wp) , it means when sun is at peak. it is around PM - 3.30PM daily in India(plane area). And panel never give 200w for more than 5 years, the efficiency reduced up to 0% at completion of 5 years of panel and 20% up to 25 years of life of panel.
Q:Who made solar panels?
Google would like to be your friend - Try - who invented solar panels and see what turns up.
