Why is it better to have solar panels face west rather than east?

Solar panels should never be pointed west or east. They should be set to absorb as much day time solar energy as possible from both east and west so that means SOUTH only! Be sure there is no shading from trees in your location or you woun't benefit from full energy output.  I recommend you pick up a issue of "HOME POWER" magazine and become familiar with how to do installations. In addition many solar supply houses have free information for the installation of solar power systems.

it seems to rise in the east and set in the west, but it is really the rotation of the earth, so the sun isnt really rising or setting at all

yeah, both have been done. Neither were very useful, but that may change if solar cells get more effeicient, and batteries get better.

The sun isn't moving.\nThe sun appears to move east to west because Earth is rotating on its axis (actually, the earth is rotating on its axis, as well as rotating around the sun)

We can do a lot better than nature.\n\nOur best solar cells can exceed 20% efficiency while photosynthesis is only about 1% efficient.\n\nWhile we might be able to mimic it the low efficiency would make it seem like a waste of time.

Yeah, what Eugene said.  Electrons going from one end to the other get pushed sideways a bit cause they are moving charges in a transverse magnetic field ;  so there are more on the left than the right but they don't like being close to other electrons much and will move back again if you give them the chance, big fat wires give them more of a chance to move back in the direction that you don't want them to go. \n\nNow you tell me why semiconductor hall effect sensors are so much more sensitive than sensors based on thin metal films.

Solar energy is available in a large quantity, in fact much larger than all other safe energy sources put together. Energy obtained from coal, petroleum, other carbon based products and that obtained from nuclear fusion/fission is not safe for the enviornment.\nSo Solar energy has two major advantages -\n1. Abundant, hence making it cheap.\n2. Environmental friendly.

not necessarily its used for avoiding DAMN BURN INS....for crt monitors...its more effiecient if you use POWER SAVING OPTIONS....

A mirror preserves absolute direction, both horizontally and vertically.  Say you're facing west; the reflection of your north hand is on the same side of the room as your real north hand -- namely the north side.  And the reflection of the top of your body is toward the ceiling, just like the real top of your body.  That's because north vs. south and up vs. down are the same for everybody.  But right and left are not absolute directions.  Your north hand is on the right because you're facing west.  If someone were facing east, their north hand would be on the left.  And your reflection in this example _is_ facing east because you are facing west, and the reflection is looking back at you.  So, your reflection's north hand, which is the same as your north (that is, right) hand, is its left hand.

Solar energy is a success story. It already supplies electricity to several hundred thousand people around the world, provides employment for over ten thousand and generates business worth more than $1 billion dollars. In the future, the pace of change and progress could be even more rapid as the solar industry unlocks its hidden promise.\n\nThe benefits of solar power are compelling: environmental protection, economic growth, job creation, diversity of fuel supply and rapid deployment, as well as the global potential for technology transfer and innovation.\n\nThe underlying advantage of solar energy is that the fuel is free, abundant and inexhaustible. The total amount of energy irradiated from the sun to the earth’s surface is enough to provide more than 10,000 times the annual global energy consumption. Yet these benefits remain largely untapped; most energy decisions taken today overlook solar power as a modular technology which can be rapidly deployed to generate electricity close to the point of consumption. Phasing in solar photovoltaics therefore requires a shift from centralised to decentralised power production, offering far greater control to individual consumers.

face the sun in the morning and south is on your right... so split the difference.

nope because the sun rises in the east and sets in the west :)

The earth rotates on an axis. In the summer, your hemisphere is tilted towards the sun. This results in longer days, and the sunlight hitting the earth more straight on.\n\nIn the winter, your hemisphere is tilted away from the sun. This results in shorter days, and the light hits the earth at a greater angle. More light is reflected off the atmosphere and off the earth itself, which contributes to less heat absorbed. Also, the same area of sunlight is spread over a greater area (like shining a torch sideways along the ground), this reduced density of sunlight on the earth also means less heat is absorbed.\n\nThe seasons are more distinct further from the equator where the tilt has more of an effect. On the equator, there are actually 2 longest and 2 shortest days each year and less distinct seasons, as when the earth is on either side of the sun (during autumn/spring seasons) the sun is directly above the equator, no matter which side of the sun the earth is on.

Because if you use bad insulators like metal the energy will escape as heat therefore increase the temperature during summer but if you use a good insulator that energy won't escape thus not increasing the temperature or anything not needed (energy that is ).

Good question!  However, 1-way mirrors are not really 1-way: they let as much light out as they do in!  They depend on the fact that the "invisible" side is less well illuminated than the "visible" side.

Z-shape or zigzag, because it is a nice shape or a nice design and unique. It's okay for houses to face the steets but it must face the sunlight coz' they say that it's bad luck if it will not be facing the sunlight and it's not really best if you will build your houses near the streets especially when you live in a big community or in an urban place because accidents always happens in that area but if you live in a peaceful place like in a rural or province area it's okay.\nYou could also choose a one-storey house or two or more than storey house.

no that is why our electricity is ran house to house in ac.  it is safer to operate ac and also more energy efficient.
