Q:how do you make solar panel?
Solar panel is a sheet of highly expensive, purest Silicon manufactured in a factory of exceptional killingly stringent specifications. You can't do that as a cottage industry, at least the material.
Q:Solar Panels: How long will it be before solar panels are cheap & effecient enough so that everyone?
Solar panels are cost effective if they are used over their payback period. The problem is that the down payment is expensive, and the payback period is maybe 0-20 years, so very few people actually expect to own their homes for 0-20 years. It also only really makes sense in areas that buy back electricity generated during the day when you're not using it. In Germany and other european countries, power companies are required to buy back electricity at a higher price than they sell it for--this reduces the payback period and is a great incentive for solar panels. For this reason, they are much more popular over there. Given a little time for the price to fall and given some change in energy policy, solar panels will become more cost effective in the future. Depends on who gets elected, though. There is a solution to the payback period problem, though. Rather than homeowners taking on the long payback period in homes they may not own long enough, some companies are buying panels and leasing them to homeowners. In exchange, homeowners get reduced electric bills, that pay off the lease payments, plus a little extra. I think this is the way to go. check out the link below.
Q:Why are solar panels only 0% efficient?
Mainly due to reflection (micro-structuring of the surface helps here), incorrect wavelength of the light (the panel is only sensitive to a certain wavelength range) and heating of the panel (due to the incident light/thermal radiation). The remainder is either reflected or absorbed by the cell and re-emitted as heat. Absorption by e.g. the glass panel is slight (a few %), as is absorption/reflection by the necessary surface contacts (again, a few %). Higher efficiency is possible, but brings its own drawbacks (like higher cost). You could now go into two directions: - high efficiency cells/panels with (likely) higher cost and complexity for mounting (like lens or mirror based systems, aka concentrator systems, that increase the light level on the cells in order to increase efficiency) - low cost systems (cheap as dirt) that will allow you to cover every surface of a building, efficiency is less important if you can compensate by a much larger covered area As to the efficiency limit: there is a theoretical limit (from thermodynamics - don't ask me how or why) in the range of 30...40%, depending on which publication you want to believe in.
Q:Do solar panels keep a structure cooler?
it would depend on the type of paneling. And compared to what. Since it absorbs solar energy, that includes some heat. Compared to white paint, which may reflect more of the heat, it depends.
Q:Self build solar panel ?
You would need a pretty hefty panel, the standard power charger is like 0 watts. You would need more than that for the overhead of charging a battery and converter loss. You would need a regulated supply, like a car ipad adapter, I seen them for like 20 bucks. They have to say Ipad , the ipod/iphone chargers have less power and would charge much slower.
Q:Maintenance of Solar Panel?
New solar panels are clean and shiny and they look cool. Then they get dirty with dust and debris caught on the wind and residues left behind by rain and birds. Solar panels must be regularly cleaned and maintained in order to keep them operating efficiently and maximize the amount of sunlight they convert into electricity. Unlike windows your solar system needs to have a clean and clear surface to ensure they are working at their maximum efficiency. If they are not at their optimum performance it means they are not producing the amount of electricity that they could be. Solar panels will attract dirt, dust, soot, pollen, tree sap and salt crystals in coastal regions creating a fine layer of grime. This layer reduces the amount of light reaching the silicon cells under the glass surface and reduces the panel's effectiveness. A solar panel that has never been cleaned could be producing almost a third less power than it otherwise could be. Some have reported a ten to fifteen percent loss of solar output due to dirty panels. From the ground the panels may appear to be clean, just like your windows. Up close however you can see the grime that has built up from the dirt and pollution in the air. A more noticeable deposit that can be left on panels is bird droppings. These tend to completely block the light from areas of the photovoltaic panel and can considerable reduce its effectiveness. See much more about solar panels maintenance below link
Q:Improvising Solar Panel Made from Old CD or DVD? Possible or not?
A solar electric panel? No. Solar electric cells, or more properly photovoltiac (PV) cells, are made from specially prepared (doped) wafers of silicon, much like transistors and diodes. CDs and DVDs are made from plastic plated with aluminum. They don't have anything to do with each other. Of course you can make a reflector out of CDs or DVDs, and you could use a bunch of them to focus sunlight on a water tank or something - this is called solar thermal generation. (That's what that ehow page is talking about, not generating electricity.) But there are much better things to use for mirrors.
Q:how much do solar panel batteries cost?
Kirraina is right the only ingredient i'm able to upload is purchase the ideal, as quickly as. in case you purchase 2nd or 0.33 ideal it is not long till you need to purchase it lower back. something I study a protracted time in the past, and it nonetheless is sensible as we talk- do you comprehend why the wealthy are wealthy? they simply yet something as quickly as! EG. a stable refrigerator will final 30 years, slightly bit junk 5-6 years. a stable refrigerator isn't 5 X greater funds than the main inexpensive one. subsequently that's the ideal deal?there is another attention, new technologies, attempt and discover something that is unquestionably upgradeable. playstation overlook approximately automobile batteries they are no longer outfitted for image voltaic platforms. you need to use ideal deep charging batteries. Sorry, definite they are costly besides.
Q:How I can get 300- 500 Wh of energy using Solar Panel?
If okorder.com . If you must store this energy, that's another trick involving other equipment.
Q:Solar Panels Energy Theory?? ENERGY?
No. okorder.com/... Since then they have only improved. CdTe efficiencies have increased, partly by reducing material use (particularly the depth of the CdS layer)
